Important notice for California retail buyers of Mercedes-Benz automobiles

after a reasonable number of repair attempts during the period of one year or 12 000 miles from original delivery of
the vehicle. A reasonable number of repair attempts is presumed for a retail buyer (1) if the vehicle is out of service by
reason of repair of substantial nonconformities for a cumulative total of more than 30 calendar days or (2) the same
substantial non-conformity has been subject to repair four or more times and you have at least once directly

changes in design and equipment. Therefore, information, illustrations and descriptions in this Operator’s Manual

Warning!
This Sport Utility Vehicle is designed for both on-road and off-road use. It can go places and perform tasks for
which conventional 2-wheel drive passenger cars were not intended. This vehicle will handle and maneuver
differently from conventional passenger cars in driving conditions which may occur on streets, highways and
off-road use.
This vehicle has a higher ground clearance and a higher center of gravity than many passenger cars. As with
other vehicles of this type, if you make sharp turns at excessive speeds or abrupt maneuvers, the vehicle may
roll over or may go out of control and crash. Utility vehicles have a significantly higher rollover rate than
other types of vehicles. Failure to operate this vehicle safely may result in an accident, rollover of the vehicle,
and severe or fatal injury.
Before you start to drive this vehicle, read the Operator’s Manual. Take time to become familiar with the
driving characteristics of this vehicle. Be sure you are familiar with all vehicle controls. Learn how your
vehicle handles on different road surfaces. Do not attempt sharp turns at excessive speeds or abrupt
maneuvers or other unsafe driving actions that can cause loss of vehicle control. When driving off-road or
working the vehicle, do not overload it. And, always wear your seat belts at all times. In a rollover crash, an
unbelted person is significantly more likely to die than a person wearing a seat belt.

Seats, front
Warning!
Warning!
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause the
driver to lose control of the vehicle.
When leaving the vehicle always remove the key
from the steering lock, and lock your vehicle.
Do not leave children unattended in the vehicle or
with access to an unlocked vehicle. Unsupervised
use of vehicle equipment may cause serious
personal injury.
Never ride in a moving vehicle with the backrest
reclined. Sitting in an excessively reclined position
can be dangerous. You could slide under the seat
belt in a collision. If you slide under it, the belt
would apply force at the abdomen or neck. That
could cause serious or even fatal injuries. The
backrest and seat belt provide the best restraint
when the wearer is in an upright position and the
belt is properly positioned on the body.
Caution!
Do not remove head restraints except when mounting
seat covers. For removal see page 43. Whenever head
restraints have been removed be sure to reinstall them
before driving.
Never place hands under seat or near any moving
parts while a seat is being adjusted.

Important!
Prior to operating the vehicle, the driver should adjust
the seat height for proper vision as well as fore/aft
placement and backrest angle to insure adequate
control, reach, operation, and comfort. The head
restraint should also be adjusted for proper height. See
also airbag section on page 56 for proper seat
positioning.
Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmartTM compatible child seat,
which operates with the BabySmartTM system
installed in the vehicle to deactivate the passenger
side front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury can result.
In addition, also adjust the steering wheel to ensure
adequate control, reach, operation, and comfort.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in the back
seats and be seated in an appropriate infant or
child restraint system, which is properly secured
with the vehicle’s seat belt, fully in accordance
with the child seat manufacturer’s instructions.
Both the inside and outside rear view mirrors should be
adjusted for adequate rearward vision.
Fasten seat belts. Infants and small children should be
seated in a properly secured restraint system that
complies with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Vehicle Safety
Standard 213.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints are
not properly secured in the vehicle and the child is
not properly secured in the child restraint.
All seat, head restraint, steering wheel, and rear view
mirror adjustments as well as fastening of seat belts
should be done before the vehicle is put into motion.

Seat belts and integrated restraint system
Your vehicle is equipped with seat belts for all seats,
emergency tensioning retractors for front and second
row outboard seat belts, dual front airbags and door
mounted side impact airbags. Their protective functions
are designed to complement one another.
Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmartTM compatible child seat,
which operates with the BabySmartTM system
installed in the vehicle to deactivate the passenger
side front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury will result.
Seat belts
Important!
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in back seats
and be seated in an appropriate infant or child
restraint system, which is properly secured with
the vehicle’s seat belt, fully in accordance with the
child seat manufacturer’s instructions.
Laws in most states and all Canadian provinces require
seat belt use.
All states and provinces require use of child restraints
that comply with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Vehicle Safety
Standard 213.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints are
not properly secured in the vehicle and the child is
not properly secured in the child restraint.
All child restraint systems are designed to be secured in
vehicle seats by lap belts or the lap belt portion of a lap-
shoulder belt.
For your safety and that of your passengers we strongly
recommend their use.

Warning!
Warning!
Never ride in a moving vehicle with the backrest
reclined. Sitting in an excessively reclined position
can be dangerous. You could slide under the seat
belt in a collision. If you slide under it, the belt
would apply force at the abdomen or neck. That
could cause serious or even fatal injuries. The
backrest and seat belt provide the best restraint
when the wearer is in an upright position and the
belt is properly positioned on the body.
Failure to wear and properly fasten and position
your seat belt greatly increases your risk of
injuries and their likely severity in an accident.
You and your passengers should always wear seat
belts.
If you are ever in an accident, your injuries can be
considerably more severe without your seat belt
properly buckled. Without your seat belt buckled,
you are much more likely to hit the interior of the
vehicle or be ejected from it. You can be seriously
injured or killed.
Note:
For cleaning and care of the seat belts, see page 282.
In the same crash, the possibility for injury or
death is lessened if you are wearing your seat belt.
Seat belt nonusage warning system
Warning!
After starting the engine, a warning sounds and the seat
belt warning lamp < remains illuminated for a short
time if the driver’s seat belt is not fastened.
Never let more people ride in the vehicle than there
are seat belts available. Be sure everyone riding in
the vehicle is correctly restrained with a separate
seat belt.

USE SEAT BELTS PROPERLY.
• Seat belts can only work when used properly.
Never wear seat belts in any other way than as
described in this section, as that could result
in serious injuries in case of an accident.
• Each occupant should wear their seat belt at all
times, because seat belts help reduce the
likelihood of and potential severity of injuries
in accidents, including rollovers. The
integrated restraint system includes “SRS”
(driver airbag, front passenger airbag, front
and rear door mounted side impact airbags),
“ETR” (seat belt emergency tensioning
retractors for the outboard passenger seats
[except in the optional 3rd row seats]), and
front seat knee bolsters. The system is
designed to enhance the protection offered to
properly belted occupants in certain frontal
(front airbags) and side (side impact airbags)
impacts which exceed preset deployment
thresholds.
Operation
The inertia reel stops the belt from unwinding during
sudden vehicle stops or when quickly pulling on the
belt. The locking function of the reel may be checked by
quickly pulling out the belt.
Unfastening of seat belts
Push the release button (3) in the belt buckle (2).
Allow the retractor to completely rewind the seat belt by
guiding the latch plate (1).

• Never wear the shoulder belt under your arm,
against your neck or off your shoulder. In a
crash, your body would move too far forward.
That would increase the chance of head and
neck injuries. The belt would also apply too
much force to the ribs or abdomen, which
could severely injure internal organs such as
your liver or spleen.
• Each seat belt should never be used for more
than one person at a time. Do not fasten a seat
belt around a person and another person or
other objects.
• Belts should not be worn twisted. In a crash,
you wouldn’t have the full width of the belt to
manage impact forces. The twisted belt against
your body could cause injuries.
• Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, keys etc., as these might
cause injuries.
• Pregnant women should also use a lap-
shoulder belt. The lap belt portion should be
positioned as low as possible on the hips to
avoid any possible pressure on the abdomen.
• Position the lap belt as low as possible on your
hips and not across the abdomen. If the belt is
positioned across your abdomen, it could cause
serious injuries in a crash.
• Never place your feet on the instrument panel
or on the seat. Always keep both feet on the
floor in front of the seat.

Warning!
USE CHILD RESTRAINTS PROPERLY.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints are
not properly secured in the vehicle and the child is
not properly secured in the child restraint.
Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmartTM compatible child seat,
which operates with the BabySmartTM system
installed in the vehicle to deactivate the passenger
front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury will result.
Children too big for child restraint systems must
ride in back seats using regular seat belts. Position
shoulder belt across chest and shoulder, not face or
neck. A booster seat may be necessary to achieve
proper belt positioning.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in back seats
and be seated in an appropriate infant or child
restraint system, which is properly secured with
the vehicle’s seat belt, fully in accordance with the
child seat manufacturer’s instructions.

BabySmartTM airbag deactivation system
The passenger side front airbag will not deploy
only if the 7 indicator lamp remains
illuminated.
Special BabySmartTM compatible child seats, designed
for use with the Mercedes-Benz system and available at
any authorized Mercedes-Benz Center are required for
use with the BabySmartTM airbag deactivation system.
Please be sure to check the indicator every time
you use the special system child seat.
Should the light go out while the restraint is
installed, please check installation. If the light
remains out, do not use the BabySmartTM restraint
to transport children on the front passenger seat
until the system has been repaired.
With the special child seat properly installed, the
passenger front airbag will not deploy. The 7
indicator lamp located in the instrument cluster will be
illuminated, except with key removed or in steering lock
position 0. The system does not deactivate the door
mounted side impact airbag.
Self-test BabySmartTM
Warning!
without special child seat installed
The BabySmartTM Airbag Deactivation System will
ONLY work with a special child seat designed to
operate with it. It will not work with child seats
which are not BabySmartTM compatible.
After turning key in steering lock to position 1 or 2, the
7 indicator lamp located in the instrument cluster
comes on for approximately 6 seconds, extinguishes,
then blinks once.
Never place anything between seat cushion and
child seat (e.g. pillow), since it reduces the
effectiveness of the deactivation system.
If the indicator lamp should not come on or is
continuously lit, the system is not functioning. You must
see an authorized Mercedes-Benz Center before seating
any child on the front passenger seat.
Follow the manufacturer’s instructions for
installation of special child seats.

Supplemental restraint system (SRS)
Seat belt fastened
Airbags are intended as a supplement to seat belts.
Airbags alone cannot protect as well as airbags plus
seat belts in impacts for which the airbags were
designed to operate, and do not afford any protection
whatsoever in crashes for which the airbags are not
designed to deploy.
• first threshold exceeded: ETR activates
• second threshold exceeded: airbag also activates
Seat belt not fastened
Front seats:
The SRS uses two crash severity levels (thresholds) to
activate either the Emergency Tensioning Retractor
(ETR) or front airbag or both. Activation depends on the
direction and severity of the impact exceeding the
preset thresholds and whether the seat belt is fastened.
• first threshold exceeded:
airbag activates, but not ETR
Rear outer seats:
• first threshold exceeded:
ETR activates
Driver, front passenger and rear outer seat systems
operate independently of each other.

Emergency tensioning retractor (ETR)
In cases of other frontal impacts, angled impacts, roll-
overs, certain side impacts, or other accidents without
sufficient frontal or rear impact forces, the emergency
tensioning retractors will not be activated. The driver
and passengers will then be protected by the fastened
seat belts and inertia reel in the usual manner.
The seat belts for the outboard passenger seats (except
in the optional 3rd row seats) are equipped with
emergency tensioning retractors. These tensioning
retractors are located in each belt’s inertia reel and
become operationally ready with the key in steering
lock position 1 or 2.
For seat belt and emergency tensioning retractor see
page 63.
The emergency tensioning retractors are designed to
activate only when the seat belts are fastened during
frontal impacts exceeding the first threshold of the SRS
and in rear impacts exceeding a preset severity level.
They remove slack from the belts in such a way that the
seat belts fit more snugly against the body restricting its
forward movement as much as possible.

Airbags
1 Driver airbag
2 Front passenger airbag
The most effective occupant restraint system yet
developed for use in production vehicles is the seat belt.
In some cases, however, the protective effect of a seat
belt can be further enhanced by an airbag.
The passenger front airbag is located in the dashboard
ahead of the front passenger.
The driver airbag is located in the steering wheel hub.

The side impact airbags are located in the front and rear
doors.
Door mounted side impact airbags can provide
increased protection to belted outboard occupants on
the impacted side of the vehicle in side impacts
exceeding its preset threshold.
In conjunction with wearing the seat belts, the driver
and front passenger airbags can provide increased
protection for the driver and front passenger in certain
frontal impacts exceeding preset thresholds.
Important!
The operational readiness of the airbag system is
verified by the indicator lamp “SRS” in the instrument
cluster when turning the key in steering lock to
position 1 or 2. If no fault is detected, the lamp will go

out after approximately 5 seconds; after the lamp goes
out, the system continues to monitor the components
and circuitry of the airbag system and will indicate a
malfunction by coming on again. If the lamp does not
come on at all or if it fails to extinguish after
approximately 5 seconds or if it comes on thereafter,
a malfunction in the system has been detected.

Warning!
The following system components are monitored or
undergo a self-check: crash-sensor(s), airbag ignition
circuits, front seat belt buckles, emergency tensioning
retractors, seat sensor.

Front airbags
Note:
Heavy objects on front passenger seat can cause the
side impact airbag to deploy in a crash.
The driver and front passenger front airbags are
designed to activate only in certain frontal impacts
exceeding a preset threshold.
Important!
The front passenger airbag deploys only if the front
passenger seat is occupied and the ü indicator lamp
in the instrument cluster is not illuminated.
Airbags are designed to activate only in certain
frontal (front airbags) impacts, or side (side impact
airbags) impacts which exceed preset thresholds.
Note:
Only during these types of impacts, if of sufficient
severity to meet the deployment thresholds, will
they provide their supplemental protection.
Heavy objects on the front passenger seat can appear to
the “SRS” to indicate the presence of an occupant in
that seat which causes the passenger front airbag to
deploy in a crash exceeding the appropriate threshold.
The driver and passenger should always wear their
seat belts, otherwise it is not possible for the airbags
to provide their intended supplemental protection.
Side impact airbags
In cases of other frontal impacts, angled impacts,
roll-overs, other side impacts, rear collisions, or
other accidents in which the airbags are not
designed to deploy, the airbags will not be activated.
The driver and passenger will then be protected by
the fastened seat belts.
The side impact airbags are designed to activate only in
certain side impacts exceeding a preset threshold. Only
the side impact airbags on the impacted side of the
vehicle deploy.
The side impact airbag for the front passenger deploys
only if the front passenger seat is occupied.
We caution you not to rely on the presence of the
airbags in order to avoid wearing your seat belt.
Side impact airbags operate best in conjunction with a
properly positioned and fastened seat belt.

Your vehicle was originally equipped with airbags
which are designed to activate in certain impacts
exceeding a preset threshold to reduce the potential
and severity of injury. It is important to your safety
and that of your passenger that you replace deployed
airbags and repair any malfunctioning airbags to
ensure the vehicle will continue to provide crash
protection for occupants.
Warning!
Airbags are designed to reduce the potential of
injury in certain frontal (front airbags) impacts,
and side (side impact airbags) impacts which may
cause significant injuries, however, no system
available today can totally eliminate injuries and
fatalities.
The activation of the “SRS” temporarily releases a
small amount of dust from the airbags. This dust,
however, is neither injurious to your health, nor
does it indicate a fire in the vehicle. The dust might
cause some temporary breathing difficulty for
people with asthma or other breathing trouble. To
avoid this, you may wish to get out of the vehicle as
soon as it is safe to do so. If you have any breathing
difficulty but cannot get out of the vehicle after the
airbag inflates, then get fresh air by opening a
window or door.
Warning!
To reduce the risk of injury when the front airbags
inflate, it is very important for the driver and front
passenger to always be in a properly seated
position and to wear their seat belts.
For maximum protection in the event of a collision
always be in normal seated position with your back
against the backrest. Fasten your seat belt and
ensure that it is properly positioned on your body.
Since the airbag inflates with considerable speed
and force, a proper seating and hands on steering
wheel position will help to keep you at a safe
distance from the airbag. Occupants who are
unbelted, out of position or too close to the airbag
can be seriously injured by an airbag as it inflates
with great force in the blink of an eye:
Download from Www.Somanuals.com. All Manuals Search And Download.
• Sit properly belted in an upright position with
your back against the backrest.
• Occupants, especially children, should never
lean their heads in the area of the door where
the side airbag inflates. This could result in
serious injuries or death should the airbag be
triggered. Always sit upright, properly use the
seatbelts and appropriate size infant or child
restraint system.
• Adjust the driver’s seat as far as possible
rearward, still permitting proper operation of
vehicle controls. The distance from the center
of the driver’s breastbone to the center of the
airbag cover on the steering wheel must be at
least ten inches (25 cm) or more. You should be
able to accomplish this by a combination of
adjustments to the seat and steering wheel. If
you have any problems, please see your
• Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized BabySmartTM
compatible child seat, which operates with the

will be struck by the airbag when it inflates in
a crash. If this happens, serious or fatal injury
can result.
authorized Mercedes-Benz Light Truck Center.
• Do not lean with your head or chest close to the
steering wheel or dashboard.
• Keep hands on the outside of steering wheel
rim. Placing hands and arms inside the rim
can increase the risk and potential severity of
hand/arm injury when the driver front airbag
inflates.
Failure to follow these instructions can result in
severe or fatal injuries to you or other occupants.
• Adjust the front passenger seat as far as
possible rearward from the dashboard when
the seat is occupied.

Warning!
To help avoid the possibility of injury, please follow
these guidelines: (1) occupants, especially
children, should never place their bodies or lean
their heads in the area of the door where the side
airbag inflates. This could result in serious
injuries or death should the side airbag be
activated; (2) always sit upright, properly use the
seat belts and use an appropriately sized infant or
child restraint system for all children 12 years old
or under; and (3) always wear seat belts properly.
Accident research shows that the safest place for
children in an automobile is in the rear seat.
Should you choose to place a child 12 years old or
under in the front passenger seat of your vehicle,
you must properly use a BabySmartTM child
restraint which will turn off the passenger side
front airbag. BabySmartTM will not, however, turn
off the vehicle’s side impact airbag.
It should be noted that with respect to both front
and rear side impact airbags there is a possibility
for a side airbag related injury if occupants,
especially children, are not properly seated or
restrained when next to a side airbag which needs
to deploy rapidly in a side impact in order to do its
job.
If you believe that, even with the use of these
guidelines, it would be safer for your rear seat
occupants to have both rear door mounted side
airbags deactivated, then deactivation can be
accomplished upon your written election to do so at
your authorized Mercedes-Benz Center at an
additional cost. Please contact your local
authorized Mercedes-Benz Center or call our Client
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.

Safety guidelines for the seat belt,
emergency tensioning retractor and airbag
• An airbag system component within the
steering wheel gets hot after the airbag has
inflated. Do not touch.
Warning!
• Improper work on the system, including
incorrect installation and removal, can lead to
possible injury through an unintended
activation of the “SRS”.
• Damaged seat belts or belts that were highly
stressed in an accident must be replaced and
their anchoring points must also be checked.
Use only belts installed or supplied by an
authorized Mercedes-Benz Light Truck Center.
• No modifications of any kind may be made to
any components or wiring of the “SRS”. This
includes changing or removing any component
or part of the “SRS”, the installation of
additional trim material, badges etc. over the
steering wheel hub, front passenger airbag
cover, or front door trim panels, and
• Do not pass belts over sharp edges.
• Do not make any modification that could
change the effectiveness of the belts.
• Airbags and ETR’s are designed to function on
a one-time-only basis. An airbag or emergency
tensioning retractor (ETR) that was activated
must be replaced.
installation of additional electrical/electronic
equipment on or near “SRS” components and
wiring. Keep area between airbags and
occupants free of objects (e.g. packages,
purses, umbrellas, etc.).

• In addition, through improper work there is
the risk of rendering the “SRS” inoperative or
causing unintended airbag deployment. Work
on the “SRS” must therefore only be performed
by an authorized Mercedes-Benz Light Truck
Center.
• Given the considerable deployment speed and
the textile structure of the airbags, there is the
possibility of abrasions or other injuries
resulting from airbag deployment.
When you sell the vehicle we strongly urge you to give
notice to the subsequent owner that it is equipped with
an “SRS” by alerting him to the applicable section in the
Operator’s Manual.
• For your protection and the protection of
others, when scrapping the airbag unit or
emergency tensioning retractor, our safety
instructions must be followed. These
instructions are available at your authorized
Mercedes-Benz Light Truck Center.

Infant and child restraint systems
Warning!
We recommend that all infants and children be properly
restrained at all times while the vehicle is in motion. All
lap-shoulder belts except the driver’s seat belt have
special seat belt retractors for secure fastening of child
restraints.
Never release the seat belt buckle while vehicle is
in motion, since the special seat belt retractor will
be deactivated.
Important!
To fasten a child restraint follow child restraint
instructions for routing. Then pull shoulder belt out
completely and let it retract. During the seat belt
retraction a ratcheting sound can be heard to indicate
that the special seat belt retractor is activated. The belt
is now locked. Push down on child restraint to take up
any slack.
The use of infant or child restraints is required by law in
all 50 states and all Canadian provinces.
Infants and small children should be seated in an
appropriate infant or child restraint system properly
secured by a lap-shoulder belt, and that complies with
U.S. Federal Motor Vehicle Safety Standard 213 and
Canadian Motor Vehicle Safety Standard 213.
A statement by the child restraint manufacturer of
compliance with this standard can be found on the
instruction label on the restraint and in the instruction
manual provided with the restraint.
To deactivate, release seat belt buckle and let seat belt
retract completely. The seat belt can again be used in
the usual manner.
Note:
When using any infant or child restraint system, be sure
to carefully read and follow all manufacturer’s
instructions for installation and use.
For child seats with mounting fittings for tether
anchorages refer to page 67 (installation of infant and
child restraint systems).
Please read and observe warning labels affixed to inside
of vehicle and to infant or child restraints.

Warning!
Infants and small children should never share a
seat belt with another occupant. During an
accident, they could be crushed between the
occupant and seat belt.
Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmartTM compatible child seat,
which operates with the BabySmartTM System
installed in the vehicle to deactivate the passenger
front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury can result.
Children too big for child restraint systems must
ride in back seats using regular seat belts. Position
shoulder belt across chest and shoulder, not face or
neck. A booster seat may be necessary to achieve
proper belt positioning for children from 41 lbs. to
the point where a lap/shoulder belt fits properly
without one.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in back seats
and be seated in an infant or child restraint system,
which is properly secured with the vehicle’s seat
belt, fully in accordance with the child seat
manufacturer’s instructions.
When the child restraint is not in use, remove it
from the vehicle or secure it with the seat belt to
prevent the child restraint from becoming a
projectile in the event of an accident.

Vehicles with automatic antiglare function:
With the key in steering lock position 2, the driver’s
side mirror reflection brightness responds to changes in
light sensitivity.
Electrolyte drops coming into contact with the vehicle
paint finish can only be completely removed while in
their liquid state, by applying plenty of water.
With gear selector lever in position “R”, or with the
interior lamps (except cargo compartment lamp)
switched on, the driver’s side mirror brightness does
not respond to changes in light sensitivity.
Notes:
The exterior mirrors have electrically heated glass. The
heater switches on automatically, depending on outside
temperature.
Warning!
If an exterior mirror housing is forcibly pivoted from its
normal position, it must be repositioned by applying
firm pressure until it snaps into place.
In the case of an accident liquid electrolyte may
escape the mirror housing when the mirror glass
breaks.
Electrolyte has an irritating effect. Do not allow the
liquid come into contact with eyes, skin, clothing,
or respiratory system. In cases it does, immediately
flush affected area with water, and seek medical
help if necessary.

Coolant temperature gauge
Warning!
During severe operating conditions and stop-and-go city
traffic, the coolant temperature may rise close to the red
marking.
• Driving when your engine is badly overheated
can cause some fluids which may have leaked
into the engine compartment to catch fire. You
could be seriously burned.
The engine should not be operated with the coolant
temperature in the red zone. Doing so may cause
serious engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
• Steam from an overheated engine can cause
serious burns and can occur just by opening
the engine hood. Stay away from the engine if
you see or hear steam coming from it.
Turn off the engine, get out of the vehicle and do
not stand near the vehicle until it cools down.

Outside temperature indicator
82
The temperature sensor is located in the front bumper
area. Due to its location, the sensor can be affected by
road or engine heat during idling or slow driving. This
means that the accuracy of the displayed temperature
can only be verified by comparison to a thermometer
placed next to the sensor, not by comparison to external
displays (e.g. bank signs etc.).
The tachometer displays the present engine speed in
revolutions per minute (RPM).
To help protect the engine, the fuel supply is interrupted
if the engine is operated above its specified limit.
Adaptation to ambient temperature takes place in steps
and depends on the prevailing driving conditions (stop-
and-go or moderate, constant driving) and amount of
temperature change.
Warning!
The outside temperature indicator is not designed
to serve as an Ice-Warning Device and is therefore
unsuitable for that purpose. Indicated
temperatures just above the freezing point do not
guarantee that the road surface is free of ice.

days not counted by the FSS can be added by your
Mercedes-Benz Light Truck Center.
After approximately 10 seconds a signal sounds, and
the display shows 10 000 miles (Canada: 15 000 km)
for approximately 10 seconds.
The interval between services is determined by the type
of driving for which the vehicle is used. For example,
driving at extreme speeds, and cold starts combined
with short distance driving in which the engine does not
reach normal operating temperature, reduce the interval
between services.
5. Release button (1).
If the FSS counter was inadvertently reset, have it
corrected at a Mercedes-Benz Light Truck Center.
Notes:
Following a completed A or B service the Mercedes-
Benz Light Truck Center sets the counter mileage to
10 000 miles (Canada: 15 000 km) and 365 days.
The FSS allows for distances between 10 000 miles
(Canada: 15 000 km) and 20 000 miles (Canada:
30 000 km), or from 365 to 730 days between services.
The counter can also be set by any individual. To do so:
1. Turn the key in steering lock to position 2.
However you choose to set your reference numbers, the
scheduled services as posted in the Service Booklet
must be followed to properly care for your vehicle.
2. Immediately press button (1) twice within one
second.

simultaneously, or the battery is only partially charged,
it is possible that the rear window defroster will
automatically turn itself off. When this happens, the
indicator lamp inside the switch starts blinking for
approximately 30 seconds. If within this time the
battery has sufficient voltage, the rear window defroster
automatically turns itself back on.
The switch is located on the center console.
With the engine running, press upper half of the switch.
Indicator lamp in switch comes on.
To cancel, press upper half of the switch again. Indicator

Loading instructions
The total load weight including vehicle occupants and
luggage/cargo should not exceed the vehicle capacity
weight indicated on the certification label which can be
found on the left door pillar.
Always place items being carried against front or rear
seat backrests, and fasten them as securely as possible.
The heaviest portion of the cargo should always be kept
as low as possible against front or rear seat backrest
since it influences the handling characteristics of the
vehicle.
The handling characteristics of a fully loaded vehicle
depend greatly on the load distribution. It is therefore
recommended to load the vehicle according to the
illustrations shown, with the heaviest items being
placed towards the front of the vehicle.
For additional safety when transporting cargo while the
rear seats are unoccupied, fasten the outer seat belts
crosswise into the opposite side buckles.

Notes:
Cargo area cover blind
The trunk is the preferred place to carry objects. The
enlarged cargo area should only be used for items which
do not fit in the trunk alone.
Warning!
Always fasten items being carried as securely as
possible using cargo tie-down rings and fastening
materials appropriate for the weight and size of the
load.
In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around
inside the vehicle, and can cause injury to vehicle
occupants unless the items are securely fastened in
the vehicle.
Closing blind:
To help avoid personal injury during a collision or
sudden maneuver, always use partition net when
transporting cargo.
Pull blind (visual protection) across luggage/cargo area,
and guide into holders (1) next to liftgate.
Never drive vehicle with the liftgate open. Deadly
carbon monoxide (CO) gases may enter vehicle
interior resulting in unconsciousness and death.
Opening blind:
To roll up blind, disengage blind and guide retraction by
its handle.

The first 1 000 miles (1 500 km)
Maintenance
The more cautiously you treat your vehicle during the
break-in period, the more satisfied you will be with its
performance later on. Therefore, drive your vehicle
during the first 1 000 miles (1 500 km) at moderate
vehicle and engine speeds.
Approximately 30 days or 2 000 miles
(Canada: 2000 km) prior to the next recommended
service, the remaining distance or days are displayed in
the multifunction indicator. See Flexible Service System
(FSS) on page 87.
During this period, avoid heavy loads (full throttle
driving) and excessive engine speeds.
We strongly recommend that you have your vehicle
serviced by your authorized Mercedes-Benz Light Truck
Center, in accordance with the Service Booklet at the
times called for by the FSS.
Avoid accelerating by kickdown. It is not recommended
to brake the vehicle by manually shifting to a lower gear.
We recommend that you select positions “3”, “2” or “1”
only at moderate speeds (for hill driving).
Failure to have the vehicle maintained in accordance
with the Service Booklet at the designated times/
mileage may result in vehicle damage not covered by
the Mercedes-Benz Limited Warranty.
After 1 000 miles (1 500 km) speeds may be gradually
increased to the permissible maximum.
Check regularly and before a long trip, see page 215.

Tele Aid
Important!
The Tele Aid system is operational providing that the
vehicle’s battery is charged, properly connected, not
damaged and cellular and GPS coverage is available.
The speaker volume of a Tele Aid call can be adjusted
using the volume control on the MCS unit. To activate,
press the “SOS” button, the Roadside Assistance
button • or the Information button ¡, depending
on the type of response required.
The initial activation of the Tele Aid system may only be
performed by completing the subscriber agreement and
placing an acquaintance call using the “SOS” button.
Failure to complete either of these steps will result in a
system that is not activated. If the system is not
activated the indicator lamp in the “SOS” button stays
on after turning electronic key in starter switch to
position 2 and the message “TELE AID – NOT
ACTIVATED” will be shown in the MCS display for
approx. 10 seconds.
Shortly after the completion of your Acquaintance Call,
you will receive a user ID and password via first call
mail. By visiting www.mbusa.com and selecting
“Tele Aid” (USA only), you will have access to account
information, remote door unlock, Info Services* profile
and more.
If you have any questions regarding activation, please
call the Response Center at 1-800-756-9018 (in the USA)
or 1-888-923-8367 (in Canada).
* Optional
System self-check
(Telematic Alarm Identification on Demand)
Initially, after turning the key in steering lock to
position 2, malfunctions are detected and indicated (the
indicator lamps in the “SOS” button, the Roadside
Assistance button • and Information button ¡
stay on longer than 10 seconds or do not come on). The
message “TELE AID – PLEASE VISIT WORKSHOP”
appears in the MCS display.
The Tele Aid system consists of three types of response;
automatic and manual emergency, roadside assistance
and information.

Important!
Once the emergency call is in progress, the indicator
lamp in the “SOS” button will begin to flash. The
message “EMERGENCY CALL – CONNECTING CALL”
appears in the MCS display. When the connection is
established, the message “EMERGENCY CALL – CALL
CONNECTED” appears in the MCS display. All
information relevant to the emergency, such as the
location of the vehicle (determined by the GPS satellite
location system), vehicle model, identification number
and color are generated.
Always make sure that the indicator lamps in the
“SOS” button, the Roadside Assistance button • and
the Information button ¡ do not remain illuminated
constantly in red and the message “TELE AID – VISIT
WORKSHOP” is not displayed in the MCS display after
the system self check.
If a malfunction is indicated as outlined above, have the
system checked at the nearest Mercedes-Benz Light
Truck Center as soon as possible.
A voice connection between the Response Center and
the occupants of the vehicle will be established
automatically soon after the emergency call has been
initiated. When a voice connection is established the
audio system mutes and the message “TELE AID –
EMERGENCY CALL ACTIVE” appears in the MCS
display. The Response Center will attempt to determine
more precisely the nature of the accident provided they
can speak to an occupant of the vehicle.
Emergency calls
An emergency call is initiated automatically:
• following an accident in which the Emergency
Tensioning Retractors (ETR’s) or airbags deploy,

automatically, dependent upon
• Selector lever position
• Accelerator position
• Vehicle speed
The gear shifting process is continuously adapted,
dependent on the driving style, the driving situation
and the road characteristics.
Important!

Important!
The selector lever is automatically locked while in
position “P”. To move the selector lever out of
position “P”, the service brake pedal must be firmly
depressed before the shift lock will release.
After selecting any driving position from “N” or “P”,
wait a moment to allow the gear to fully engage before
accelerating, especially when the engine is cold.
Shift selector lever to the desired position only when the
engine is idling normally and the service brake is
applied. Do not release the brake until ready to drive.
The vehicle may otherwise start creeping when the
selector lever is in drive or reverse position.
Accelerator position
Partial throttle = early upshifting = normal acceleration
Full throttle = later upshifting = rapid acceleration
Kickdown (depressing the accelerator beyond full
throttle) = downshifting to a lower gear = maximum
acceleration. Once the desired speed is attained, ease up
on the accelerator – the transmission shifts up again.
Warning!
It is dangerous to shift the selector lever out of “P”
or “N” if the engine speed is higher than idle speed.
If your foot is not firmly on the brake pedal, the
vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle and
hit someone or something. Only shift into gear
when the engine is idling normally and when your
right foot is firmly on the brake pedal.
Stopping
For brief stops, e.g. at traffic lights, leave the
transmission in gear and hold vehicle with the service
brake.
For longer stops with the engine idling, shift into “N”
or “P” and hold the vehicle with the service brake.
When stopping the vehicle on an uphill gradient, do not
hold it with the accelerator, use the brake. This avoids
unnecessary transmission heat build up.
Download from Www.Somanuals.com. All Manuals Search And Download.
Maneuvering
Warning!
To maneuver in tight areas, e.g. when pulling into a
parking space, control the vehicle speed by gradually
releasing the brakes. Accelerate gently and never
abruptly step on the accelerator.
When leaving the vehicle always remove the key
from the steering lock, and lock the vehicle. Do not
leave children unattended in the vehicle, or with
access to an unlocked vehicle. Children could move
the gear selector lever from position “P”, which
could result in an accident or serious injury.
To rock a vehicle out of soft ground (mud or snow),
alternately shift from forward to reverse, while applying
slight partial throttle.
Towing a trailer
Rocking a vehicle free in this manner may cause the
ABS or traction system malfunction indicator lamp to
come on. Turn off and restart the engine to clear the
malfunction indication.
If the transmission hunts between gears on inclines,
manually shift to a lower gear (select “4”, “3”, “2”
or “1”). A lower gear and reduction of speed reduces the
chance of engine overloading and/or overheating.
Warning!
At very steep inclines, not manageable with selector
lever in position “1”, switch transfer case to LOW
RANGE, see page 209 for instructions on how to engage
LOW RANGE.
Getting out of your vehicle with the selector lever
not fully engaged in position “P” is dangerous.
Also, when parked on an incline, position “P” alone
may not prevent your vehicle from moving,
possibly hitting people or objects.
For instructions on trailer towing refer to page 190.
Always set the parking brake in addition to shifting
to position “P”, see page 173 for parking brake.
When parked on an incline, also turn front wheel
against curb.

Park position
The park position is to be used when parking the
vehicle. Engage only with the vehicle stopped.
The park position is not intended to serve as a
brake when the vehicle is parked. Rather, the
driver should always use the parking brake in
addition to placing the selector lever in park to
secure the vehicle.
Notes:
The key can only be removed from the steering
lock with the selector lever in position “P”. With
the key removed, the selector lever is locked in
position “P”.
With a malfunction in the vehicle’s electrical
system the selector lever could remain locked in
position “P”. To unlock the selector lever
manually, see page 259.
The current selector lever position is indicated in the
gear range indicator display. The automatic gear
shifting process can be adapted to specific operating
conditions using the selector lever.
Reverse gear
Shift to reverse gear only with the vehicle
stopped.

Gear selection for special circumstances
No power is transmitted from the engine to the
drive axle. When the brakes are released, the
vehicle can be moved freely (pushed or towed). Do
not engage “N” while driving except to coast
when the vehicle is in danger of skidding (e.g. on
icy roads, see winter driving instructions on
page 180).
The transmission gear ranges for special circumstances
can be selected by pressing the selector lever to the
right or the left with the selector lever in position “D”.
The gear range currently selected is indicated in the
instrument cluster display.
Briefly press selector lever in the ç direction:
The transmission downshifts, one gear at a time, in the
order “4”, “3”, “2”, “1”.
Important!
Coasting the vehicle, or driving for any other
reason with selector lever in “N” can result in
transmission damage that is not covered by the
Mercedes-Benz Limited Warranty.
Press and hold selector lever in the ç direction:
The selector lever position display will switch to the
gear range currently selected by the automatic
transmission.
The transmission automatically upshifts through
5th gear. Position “D” provides optimum driving
characteristics under all normal operating
conditions.
The transmission will only shift down one gear if the
gear range currently selected has already shifted to its
highest possible gear.
Briefly press selector lever in the æ direction:
The transmission will shift from the current gear range
to the next higher gear range. If the transmission is
already in gear range “D”, an additional upshift of one
gear is possible.

Press and hold selector lever in the æ direction:
The transmission will shift from the current gear
directly to gear range “D”.
During the brief warm-up period this delayed upshift
and increased engine noise might be perceived as a
malfunction. However, neither the engine nor
transmission are negatively affected by this mode of
operation.
Warning!
The delayed upshift is effective with vehicle speeds
below 31 mph (50 km/h) at partial throttle and engine
temperatures below 95°F (35°C).
On slippery road surfaces, never downshift in order
to obtain braking action. This could result in drive
wheel slip and reduced vehicle control. Your
vehicle’s ABS will not prevent this type of loss of
control.
To avoid overrevving the engine when the selector lever
is moved to a lower gear range, the transmission will not
shift to a lower gear, if the engine’s revolutions per
minute limit would be exceeded. In this case there will
be no downshift, even when the vehicle speed reaches
the engine’s RPM limit of that gear, e.g. by applying the
service brakes. Continue driving in the usual manner.
The transmission will then shift down automatically.
Important!
With transmission in gear range “D”, “4” or “3”,
upshifting from 1st to 2nd to 3rd gear is delayed
depending on vehicle speed and engine temperature.
This allows the catalytic converter to heat up more
quickly to operating temperatures.
To prevent the engine from laboring at low RPM when
driving uphill gradients or with your vehicle heavily
loaded, the automatic transmission will downshift when
necessary to maintain engine RPM within the best
torque range.

Drinking and driving
Warning!
Drive sensibly – save fuel
Drinking or taking drugs and driving can be a very
dangerous combination. Even a small amount of
alcohol or drugs can affect your reflexes,
perceptions and judgement.
Fuel consumption, to a great extent, depends on driving
habits and operating conditions.
To save fuel you should:
The possibility of a serious or even fatal accident is
sharply increased when you drink or take drugs
and drive.
• keep tires at the recommended inflation pressures,
• remove unnecessary loads,
• remove roof rack when not in use,
• allow engine to warm up under low load use,
• avoid frequent acceleration and deceleration,
Please don’t drink or take drugs and drive or allow
anyone to drive after drinking or taking drugs.
Pedals
• have all maintenance work performed at regular
intervals by an authorized Mercedes-Benz Light
Truck Center.
Warning!
Keep driver’s foot area clear at all times. Objects
stored in this area may impair pedal movement.
Fuel consumption is also increased by driving in cold
weather, in stop-and-go traffic, on short trips and in hilly
country.
Download from Www.Somanuals.com. All Manuals Search And Download.
Power assistance
Warning!
The condition of the parking brake system is checked
each time the vehicle is in the shop for the required
maintenance service.
If the parking brake is released and the brake warning
lamp in the instrument cluster stays on and there is no
audible warning (EBP), the brake fluid level in the
reservoir is too low.
When the engine is not running, the brake and
steering systems are without power assistance.
Under these circumstances, a much greater effort is
necessary to stop or steer the vehicle.
Brake pad wear or a leak in the system may be the
reason for low brake fluid in the reservoir.
Brakes
Have the brake system inspected at an authorized
Mercedes-Benz Light Truck Center immediately.
Warning!
After driving in heavy rain for some time without
applying the brakes or through water deep enough
to wet brake components, the first braking action
may be somewhat reduced and increased pedal
pressure may be necessary to obtain expected
braking effect. Be sure to maintain a safe distance
from vehicles in front.
All checks and service work on the brake system should
be carried out by an authorized Mercedes-Benz Light
Truck Center.
Install only brake pads and brake fluid recommended by
Mercedes-Benz.
Warning!
Resting your foot on the brake pedal will cause
excessive and premature wear of the brake pads.
If other than recommended brake pads are
installed, or other than recommended brake fluid
is used, the braking properties of the vehicle can be
degraded to an extent that safe braking is
substantially impaired. This could result in an
accident.
It can also result in the brakes overheating thereby
significantly reducing their effectiveness. It may
not be possible to stop the vehicle in sufficient time
to avoid an accident.

Parking
When driving down long and steep grades, relieve the
load on the brakes by shifting into a lower gear to use
the engine’s braking power. This helps prevent
Warning!
To reduce the risk of personal injury as a result of
vehicle movement, before turning off the engine
and leaving the vehicle, always:
overheating of the brakes and reduces brake pad wear.
After hard braking, it is advisable to drive on for some
time, rather than immediately parking, so the air stream
will cool down the brakes faster.
1. Keep right foot on the service brake pedal.
2. Firmly depress parking brake pedal.
3. Move the selector lever to position “P”.
4. Slowly release the service brake pedal.
5. Turn front wheels towards the road curb.
Driving off
Apply the service brakes to test them briefly after
driving off. Perform this procedure only when the road
is clear of other traffic.
6. Turn the key to steering lock position 0 and
remove.
Warm up the engine smoothly. Do not place full load on
the engine until the operating temperature has been
reached.
7. Take the key and lock vehicle when leaving.
When starting off on a slippery surface, do not allow one
drive wheel to spin for an extended period with the ESP
switched off. Doing so may cause serious damage to the
drive train which is not covered by the Mercedes-Benz
Limited Warranty.
Important!
It is advisable to set the parking brake whenever
parking or leaving the vehicle. In addition, move
selector lever to position “P”.
When parking on hills, always set the parking brake.

Tires
Warning!
If you feel a sudden significant vibration or ride
disturbance, or you suspect that possible damage to
your vehicle has occurred, you should turn on the
hazard warning flashers, carefully slow down, and
drive with caution to an area which is a safe
distance from the roadway.
Inspect the tires and under the vehicle for possible
damage. If the vehicle or tires appear unsafe, have
it towed to the nearest Mercedes-Benz Light Truck
Center or tire dealer for repairs.
Warning!
Tread wear indicators (TWI) are required by law. These
indicators are located in six places on the tread
circumference and become visible at a tread depth of
approximately 1/16 in (1.5 mm), at which point the tire is
considered worn and should be replaced.
Do not allow your tires to wear down too far. As
tread depth approaches 1/16 in (1.5 mm), the
adhesion properties on a wet road are sharply
reduced.
Depending upon the weather and/or road surface
(conditions), the tire traction varies widely.
The tread wear indicator appears as a solid band across
the tread.

Specified tire pressures must be maintained. This
applies particularly if the tires are subjected to high
loads (e.g. high speeds, heavy loads, high ambient
temperatures).
Tire traction
The safe speed on a wet, snow covered or icy road is
always lower than on a dry road.
You should pay particular attention to the condition of
the road whenever the outside temperatures are close to
the freezing point.
Warning!
Do not drive with a flat tire. A flat tire affects the
ability to steer or brake the vehicle. You may lose
control of the vehicle. Continued driving with a flat
tire or driving at high speed with a flat tire will
cause excessive heat build-up and possibly a fire.
Warning!
If ice has formed on the road, tire traction will be
substantially reduced. Under such weather
conditions, drive, steer and brake with extreme
caution.
Aquaplaning
Depending on the depth of the water layer on the road,
aquaplaning may occur, even at low speeds and with
new tires. Reduce vehicle speed, avoid track grooves in
the road and apply brakes cautiously in the rain.
We recommend M+S rated radial-ply tires with a
minimum tread depth of approximately 1/8 in (4 mm)
for the winter season for all four wheels to insure
normal balanced handling characteristics. On packed
snow, they can reduce your stopping distance as
compared with summer tires. Stopping distance,
however, is still considerably greater than when the
road is not snow or ice covered.
Download from Www.Somanuals.com. All Manuals Search And Download.
Tire speed rating
Snow chains
ML 320 and ML 430:
Use only snow chains that are tested and recommended
by Mercedes-Benz. Your authorized Mercedes-Benz
Light Truck Center will be glad to advise you on this
subject.
Your vehicle is factory equipped with “H”-rated tires,
which have a speed rating of 130 mph (210 km/h).
An electronic speed limiter prevents your vehicle from
exceeding the tire speed rating.
Snow chains should be used on all four wheels. With
only two chains available, they should be mounted on
the rear wheels. Follow the manufacturer’s mounting
instructions.
ML 55 AMG:
Your vehicle is factory equipped with “W”-rated tires,
which have a speed rating of 168 mph (270 km/h).
Snow chains should only be driven on snow covered
roads at speeds not to exceed 30 mph (50 km/h).
Remove chains as soon as possible when driving on
roads without snow.
Despite the tire rating, local speed limits should be
obeyed. Use prudent driving speeds appropriate to
prevailing conditions.
When driving with snow chains, press the ESP control

Warning!
Even when permitted by law, never operate a
vehicle at speeds greater than the maximum speed
rating of the tires.
Model ML 55 AMG
Use of snow chains is not permissible with tire size
285/50 R 18.
Exceeding the maximum speed for which tires are

Winter driving instructions
180
If the vehicle is parked after being driven on salt treated
roads, the braking efficiency should be tested as soon as
possible after driving is resumed while observing the
safety rules in the previous paragraph.
The most important rule for slippery or icy roads is to
drive sensibly and to avoid abrupt acceleration, braking
and steering maneuvers. Do not use the cruise control
system under such conditions.
Warning!
When the vehicle is in danger of skidding, move
selector lever to position “N”. Try to keep the vehicle
under control by corrective steering action.
If the vehicle becomes stuck in snow, make sure
that snow is kept clear of the exhaust pipe and
from around the vehicle with engine running.
Otherwise, deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in unconsciousness
and death.
Caution!
Do not use LOW RANGE mode when driving on ice or
packed snow. At speeds below 18 mph (30 km/h)
vehicle steering is adversely affected by the LOW
RANGE ABS.
To assure sufficient fresh air ventilation, open a
window slightly on the side of the vehicle not
facing the wind.
Road salts and chemicals can adversely affect braking
efficiency. Increased pedal force may become necessary
to produce the normal brake effect. We therefore
recommend depressing the brake pedal periodically
when traveling at length on salt-strewn roads. This can
bring road salt impaired braking efficiency back to
normal. A prerequisite is, however, that this be done
without endangering other drivers on the road.

Winter driving
In winter operation, the maximum effectiveness of the
antilock brake system (ABS), the four wheel electronic
traction system (4-ETS+), the electronic stability
program (ESP), and electronic brake proportioning
(EBP) can only be achieved with M+S rated radial-ply
tires and/or snow chains recommended by
Have your vehicle winterized at your authorized
Mercedes-Benz Light Truck Center before the onset of
winter.
• Change the engine oil if the engine contains an oil
which is not approved for winter operation. For
viscosity (SAE/CCMC class) and filling quantity,
see page 292.
Mercedes-Benz. Snow chains maximize performance.
For driving instructions using snow chains see
page 179.
• Check engine coolant anticorrosion/antifreeze
concentration.
Deep water
Caution!
• Additive for the windshield washer and headlamp
cleaning system: Add MB Concentrate “S” to a
premixed windshield washer solvent/antifreeze
which is formulated for below freezing temperatures
see page 237.
Do not drive through flooded areas or water of unknown
depth. Before driving through water, determine its
depth. It should not be deeper than approximately
20 inches (50 cm).
• Test battery: Battery capacity drops with decreasing
ambient temperature. A well charged battery helps
to ensure that the engine can be started, even at low
ambient temperatures.
If you must drive through deep water, drive slowly to
prevent water from entering the engine compartment or
passenger compartment, being ingested by the air
intake, possibly causing damage to electrical
components or wiring, to engine or transmission that is
not covered by the Mercedes-Benz Limited Warranty.
• Tires: We recommend M+S rated radial-ply tires on
all four wheels for the winter season. Observe
permissible maximum speed for M+S rated
radial-ply tires and the legal speed limit.

Off-Road driving
Important!
Familiarize yourself with the vehicle characteristics and
gear changing before you attempt any difficult terrain
off-road driving. We recommend that you start out with
easy off-road travel.
Adjust vehicle speed to condition of terrain. The more
uneven, rutty and steeper the terrain, the lower the
speed should be.
Watch out for obstacles, such as rocks, holes,
tree-stumps, ruts.
Please read this chapter carefully before you begin
off-road travel.
Be especially careful when driving in unknown
territory. Eventually get out of the vehicle and scout the
path you intend to take.
Special driving features are available for specific kinds
of operation:
• LOW RANGE mode, see page 209
• LOW RANGE - ABS, see page 202
• LOW RANGE - 4-ETS+, see page 204
• LOW RANGE - ESP, see page 208
Continuous and speedy driving in sandy soil overcomes
the vehicle rolling resistance, and helps to prevent the
vehicle from sinking into the ground.
Do not initiate jumps with the vehicle. It interrupts the
forward momentum of the vehicle.
Sand, dirt, mud and other material having friction
property, can cause exceptional wear and tear as well as
failure of the brakes.
Engage the LOW RANGE mode before driving under
off-road conditions. For switching LOW RANGE mode on
and off see page 209.
In this case the brakes may be less effective or even fail
when you most need them. Always clean and check the
brakes following each off-road trip.
Fasten items being carried as securely as possible, see
page 136.
We recommend to keep doors, liftgate, windows, and
roof closed whenever driving in off-road mode.

Checklist before off-road driving
184
Driving in steep terrain
• Tires: Check the tread depth and maintain specified
tire pressure (see tire pressure label inside the fuel
filler flap). Check tires for possible damage and
remove foreign objects. The valve caps must be
mounted.
• Rims: Dented or bent rims can cause tire pressure
loss and damage the tire beads. For this reason
change rims before driving off-road.
1
2
• Vehicle tool kit: Check if the vehicle jack is
functional. In all cases take the vehicle tool kit, a
strong tow rope, a shovel and a small plank (to put
under the vehicle jack on sandy soil) with you.
Slope angle:
1 26° (ML 320 and ML 430)
23° (ML 55 AMG)
2 26° (ML 320 and ML 430)
21° (ML 55 AMG)
Switch to LOW RANGE mode before starting to drive up
or down steep inclines, see page 209.
Maximum vehicle climbing ability is a 60% grade.
Download from Www.Somanuals.com. All Manuals Search And Download.
Driving on embankments, slopes and other steep
inclines should only be done straight up or downhill, i.e.
in the line of gravity.
Traction in steep terrain:
Be easy on the accelerator and watch for continuous
wheel traction when driving in steep terrain.
Do not drive along the side of a slope (danger of vehicle
rollover). If in doing so, the vehicle begins to show a
tendency to roll, immediately steer into a line of gravity
(straight up or downhill).
The 4-ETS+ helps greatly when starting out on a steep
incline. The front wheels have then the tendency to slip
due to the weight reduction over the front axle. The ETS
recognizes the situation and limits the torque for the
front wheels by braking them. Simultaneously the
torque for the rear wheels is increased.
To help avoid the vehicle rolling over, never turn it
around on steep inclines. If the vehicle cannot complete
the attempted climb, back it down in reverse gear.
See page 203 for four wheel electronic traction system
(4-ETS+).
Utilize the engine’s braking power when descending a
slope, observe the engine speed (do not overrev the
engine). Apply the service brake as needed.
Driving across a hilltop:
Check the brakes after a lengthy downgrade drive.
To prevent the vehicle from speeding up too much after
climbing a hill, decelerate just ahead of a hilltop (do not
select gear range “N”). Use the momentum of the
vehicle to drive across the hilltop. Driving in this
manner prevents the vehicle from jumping across the
hilltop and thus loosing its forward momentum.
Notes:
Avoid excessive engine speeds – drive with moderate
engine speeds (max. 3000 RPM).
Select gear range “2” or “1” on the automatic
transmission, see page 165.

186
Utilize the engine’s braking power when descending a
slope, observe the engine speed (do not overrev the
engine). Apply the service brake as needed.
Select gear range “1” on the automatic transmission,
see page 165.
The special low range ABS setting allows for precise and
brief (cyclical) blocking of the front wheels, permitting
them to dig into loose ground. Remember that the front
wheels when stopped, slide across a surface, thus loose
their ability to steer the vehicle.
Drive downhill observing the same rules as driving
uphill.
Driving on embankments, slopes and other steep
inclines should only be done straight up or downhill, i.e.
in the line of gravity.
Check the brakes after a lengthy downgrade drive.
Do not drive along the side of a slope (danger of vehicle
rollover). If in doing so, the vehicle begins to show a
tendency to roll, immediately steer into a line of gravity
(straight up or downhill).
Important!
Only apply the service brake if the vehicle travels
straight downhill, i.e. in the line of gravity.

Driving through water
Switch to LOW RANGE mode before driving through
water.
Switch off the exterior lamps as well as the climate
control.
Enter the water only at a shallow spot. Never take a
running start. Drive slowly, avoiding a bow wave.
Do not stop vehicle immersed in water, and do not shut
off the engine.
To dry the brakes, apply pressure to the brake pedal
several times after leaving the water.
1 20 in (50 cm)
Before driving through water, determine its depth. It
should not be deeper than approximately
20 inches (50 cm).

Notes:
Check the vehicle clearance before crossing obstacles
that possibly could damage the undercarriage.
If possible use the assistance of a second person.
Special attention is needed when crossing obstacles on
a steep incline. The vehicle could slide sideways as a
result of its possible slanted position.
Ruts:
Select gear range “1” on the automatic transmission,
see page 165.
A number of off-road tracks or other byways have deep
ruts which can cause the undercarriage to come in
contact with the ground.
Crossing obstacles:
Select gear range “1” on the automatic transmission,
see page 165.
Drive next to the ruts rather than through them if at all
possible.
Cross obstacles (e.g. tree stumps or big rocks) very
slowly by aiming one of the front wheels at the center of
the obstacle, and repeat same with the rear wheel.
Notes:
Check the vehicle clearance.
Important!
Damage on the vehicle definitely increases the chance
for a subsequent accident.
Damage on the vehicle definitely increases the chance
for a subsequent accident.

Returning from off-road driving
• Check for brush or branches caught in the
undercarriage. They could increase the possibility of
a fire, as well as cut fuel and/or brake lines,
puncture rubber bellows of the axles or drive shafts.
Off-road driving increases strain on the vehicle.
We recommend that you inspect the vehicle for possible
damage after each off-road trip. Recognizing any
damage and a subsequent timely repair reduces the
chance of a possible breakdown or accident later on.
Warning!
If you feel a sudden significant vibration or ride
disturbance, or you suspect that possible damage to
your vehicle has occurred, you should turn on the
hazard warning flashers, carefully slow down, and
drive with caution to an area which is a safe
distance from the roadway.
Proceed as follows:
• Switch off the LOW RANGE mode, see page 209.
• Remove excessive dirt from tires, wheels, wheel
housings, and underbody. For instance, after driving
in mud, clean the radiator, chassis, engine, brakes,
and wheels from extreme dirt, using a strong jet of
water.
Inspect the tires and under the vehicle for possible
damage. If the vehicle or tires appear unsafe, have
it towed to the nearest Mercedes-Benz Light Truck
Center or tire dealer for repairs.
• Inspect frame, oil pan, brake hoses, etc., as well as
vehicle underbody for possible damage.
• Check tires for possible damage, clean all exterior
lamps, and conduct a brake test.

Trailer Hitches
Only install a trailer hitch receiver approved for your
vehicle. For information on availability and installation,
please see your authorized Mercedes-Benz Light Truck
Center.
Warning!
Failure to use proper equipment and driving
technique can result in a loss of vehicle control
when towing a trailer.
The bumpers on your vehicle are not designed for use
with clamp-type hitches. Do not attach rental hitches or
other bumper-type hitches to them.
Improper towing or failure to follow the
instructions contained in this guide can result in
serious injury. Follow the guidelines below
carefully to assure safe trailer operation.
To reduce the possibility of damage, remove the hitch
ball adaptor from the receiver when not in use.
Ask your authorized Mercedes-Benz Light Truck
Center should you require an explanation of
information contained in this guide.

Electrical connections
Vehicle and trailer weights and ratings
The vehicle is prewired to accept the seven-wire harness
included in the Mercedes-Benz approved trailer hitch
receiver kit. An additional four-pole conversion plug is
included in the Mercedes-Benz supplied trailer hitch
receiver kit. For further information, please see your
authorized Mercedes-Benz Light Truck Center.
Gross Vehicle Weight Rating (GVWR) is the maximum
permissible vehicle weight: 6005 lbs. (2724 kg)
Gross Vehicle Weight (GVW): comprises weight of
vehicle including fuel, tools, spare wheel, installed
accessories, passengers, cargo and trailer tongue. It
must never exceed the GVWR.

Loading a trailer
192
Checking weights of vehicle and trailer
When loading a trailer, you should observe that neither
the permissible GTW, nor the GVWR are exceeded.
To assure that the tow vehicle and trailer are in
compliance with the maximum permissible weight
limits, and to know the actual weights, have the loaded
rig (tow vehicle including driver, passengers and cargo,
trailer fully loaded) weighed on a commercial scale.
Maximum permissible values are listed on the safety
compliance certification labels for the vehicle and for
the trailer to be towed. The lowest value listed must be
selected when determining how the vehicle and trailer
are loaded.
Check the vehicle’s front and rear Gross Axle Weight
(GAW), the GTW and TW. The values as measured must
not be exceeded, according to the weight listed under
“Vehicle and trailer weight and ratings”.
We recommend loading the trailer in such a manner
that it has a tongue weight (TW) between 10% and 15%
of the GTW.
The tongue weight at the hitch ball must be added to the
GVW to prevent exceeding your Mercedes-Benz tow
vehicle’s rear GAWR.

Attaching a trailer
Caution!
Please observe maximum permitted trailer dimensions
(width and length).
Do not connect a trailer brake system (if trailer is so
equipped) directly to the vehicle’s hydraulic brake
system, as your vehicle is equipped with antilock
brakes. If you do, neither the vehicle’s brakes nor the
trailer’s brakes will function properly.
Most states and all Canadian provinces require safety
chains between your tow vehicle and the trailer. The
chains should be crisscrossed under the trailer tongue.
They must be attached to the hitch receiver, and not to
the vehicle’s bumper or axle. Be sure to leave enough
slack in the chains to permit turning corners.
The provided vehicle electrical wiring harness for trailer
towing has a brake signal wire (color orange) for
hook-up to a brake controller.
Most states and all Canadian provinces require a
separate brake system at various trailer weights.
Most states and all Canadian provinces require a
break-away switch on trailers with a separate brake
system. The switch activates the trailer brakes in the
possible event that the trailer might separate from the
tow vehicle.
You should consider using a trailer sway control system.
For further information see your authorized
Mercedes-Benz Light Truck Center.

Towing a trailer
194
The vehicle and trailer combination is heavier, and
therefore is limited in acceleration and climbing ability,
and requires longer stopping distances. It is more prone
to reacting to side wind gusts, and requires more
sensitive steering input.
There are many different laws, including speed limit
restrictions, having to do with trailer towing. Make sure
that your rig will be legal, not only for where you reside,
but also for where you will be driving. A good source for
this information can be the police or local authorities.
In order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free from
traffic.
Before you start driving with the trailer, check the
trailer hitch, break-away switch, safety chains, electrical
connections, lighting and tires. Also adjust the mirrors
to permit unobstructed view beyond rear of trailer.
If possible, do not brake abruptly, but rather engage the
brake slightly at first to permit the trailer to activate its
brake. Then increase the braking force.
If the trailer has electric brakes, start your vehicle and
trailer moving slowly, and then apply only the trailer
brake controller by hand to be sure the brakes are
working properly.
Caution!
If the trailer should begin to sway, reduce the vehicle’s
speed and use the brake controller by hand to straighten
out the vehicle and trailer. In no case should you
attempt to straighten out the tow vehicle and trailer by
increasing the speed or oversteering and stepping on
the brakes.
When towing a trailer, check occasionally to be sure that
the load is secure, and that lighting and trailer brakes
(if so equipped) are functioning properly.
Always secure items in the trailer to prevent load shifts
while driving.
Take into consideration that when towing a trailer, the
handling characteristics are different and less stable
from those when operating the vehicle without a trailer.
It is important to avoid sudden maneuvers.
If the transmission hunts between gears on inclines,
manually shift to a lower gear (select “4”, “3”, “2”
or “1”). A lower gear and reduction of speed reduces the
chance of engine overloading and/or overheating.
Download from Www.Somanuals.com. All Manuals Search And Download.
At very steep inclines, not manageable with selector
lever in position “1”, switch transfer case to LOW
RANGE, see page 209 for instructions on how to engage
LOW RANGE.
Parking
Warning!
To reduce the risk of personal injury, or damage to
the vehicle powertrain, as a result of vehicle/trailer
movement, always:
When going down a long hill, shift into a lower gear and
use the engine’s braking effect. Avoid riding the brakes,
thus overheating the vehicle and trailer brakes.
1. Keep right foot on brake pedal.
If the engine coolant rises to an extremely high
temperature (coolant temperature needle approaching
the red zone) when the air conditioner is on, turn off the
air conditioner. Engine coolant heat can be additionally
vented by opening the windows, switching the climate
control fan speed to high and setting the temperature
control to the maximum hot position.
2. Shift gear selector lever to position “N”.
3. Have a second person place wheel chocks on
downhill side of left and right trailer wheels.
4. Slowly release brake pedal and let vehicle and
trailer roll into chocks until stopped.
5. Firmly depress parking brake pedal.
6. Move gear selector lever to position “P”.
Extreme care must be exercised since your vehicle with
a trailer will require additional passing distance ahead
than when driving without a trailer. Because your
vehicle and trailer is longer than your vehicle alone, you
will also need to go much farther ahead of the passed
vehicle before you can return to your lane.
7. On inclines turn front wheels towards the road
curb.

Cruise control
1 Accelerate and set:
Lift lever briefly to set speed.
Hold lever up to accelerate.
1
2 Decelerate and set:
Depress lever briefly to set speed.
Hold lever down to decelerate.
3
Normally the vehicle is accelerated to the desired
speed with the accelerator.
Speed is set by briefly pushing the lever to
position 1 or 2. The accelerator can then be
released.
4
The speed can be increased (e.g. for passing) by
using the accelerator. After the accelerator is
released, the previously set speed will be resumed
automatically.
2
The cruise control allows you to drive in a more relaxed
manner, for example over long distances, as it
automatically maintains the set speed by actively
regulating the throttle setting.
If a set speed is to be increased or decreased
slightly, e.g. to adapt to the traffic flow, hold lever in
position 1 or 2 until the desired speed is reached, or
briefly tip the lever in the appropriate direction for
increases or decreases in 0.6 mph (1 km/h)
increments. When the lever is released, the newly
set speed remains.
Any given speed above approximately 25 mph
(40 km/h) can be maintained with the cruise control by
operating the lever.
Download from Www.Somanuals.com. All Manuals Search And Download.
3 Canceling
Important!
To cancel the cruise control, briefly push lever to
position 3.
Moving gear selector lever to position “N” switches the
cruise control off.
When you step on the brake pedal or the vehicle
speed drops below approximately 25 mph
(40 km/h), for example when driving upgrade, the
cruise control will be canceled.
Warning!
Only use the cruise control if the traffic and
weather conditions make it advisable to travel at a
steady speed.
If the cruise control cancels by itself and remains
inoperative until the engine is restarted, have the
system checked at your authorized Mercedes-Benz
Light Truck Center as soon as possible.
• The use of cruise control can be dangerous on
winding roads or in heavy traffic because
conditions do not allow safe driving at a steady
speed.
4 Resume
• The use of cruise control can be dangerous on
slippery roads. Rapid changes in tire adhesion
can result in wheel spin and loss of control.
If the lever is briefly pushed to position 4 when
driving at a speed exceeding approximately 25 mph
(40 km/h), the vehicle resumes the speed which
was set prior to the cancellation of the cruise
control. The last memorized speed is canceled when
the key in the steering lock is turned to position 1
or 0.
The “Resume” function should only be operated if
the driver is fully aware of the previously set speed
and wishes to resume this particular preset speed.

Notes:
Transmission in LOW RANGE mode
If the engine does not brake the vehicle sufficiently
while driving on a downgrade, the speed you set on the
cruise control may be exceeded. In this case the
automatic transmission shifts down (max. to 3rd gear)
to maintain the set cruise control speed by using the
engine’s braking power.
The cruise control should not be activated during off-
road driving in the LOW RANGE mode. Doing so could
reduce driving comfort.
Trailer operation
When towing a trailer, do not allow engine speed to drop
too low on inclines. Select a lower range (“3”, “2” or “1”)
in time, depending on the degree of the incline. This is
also valid with cruise control activated.
As soon as the grade eases, the automatic transmission
shifts up again dependent on the selector lever position.
Nevertheless, in some cases you may have to step on the
brake pedal to slow down. In this case the cruise control
is switched off.
At extreme inclines switch to LOW RANGE mode, see
page 209.
Use the lever to resume the previously set speed.
Note:
For detailed information see trailer towing on page 190.

Brake assist system (BAS)
Warning!
The BAS is designed to maximize the vehicle’s braking
capability during emergency braking maneuvers by
having maximum power boost applied to the brakes
more quickly in emergency braking conditions than
might otherwise be afforded solely by the driver’s
braking style. This can help reduce braking distances
over what ordinary driving and braking style might do.
The BAS complements the antilock brake system (ABS).
BAS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the
traction afforded. The BAS cannot prevent
accidents, including those resulting from excessive
speed in turns, following another vehicle too
closely, or aquaplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of a BAS equipped vehicle must never
be exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the
safety of others.
Applying the brakes very quickly results in maximum
BAS assistance.
To receive the benefit of the system you must apply
continuous full braking power during the stopping
sequence. Do not reduce brake pedal pressure.
Once the brake pedal is released, the BAS is deactivated.
The malfunction indicator lamp for the electronic
stability program (ESP) is combined with the BAS
malfunction indicator lamp.

The BAS/ESP malfunction indicator lamp in the
instrument cluster comes on with the key in steering
lock position 2 and should go out with the engine
running.
If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the BAS and
the ESP are switched off. When the voltage is above this
value again, the malfunction indicator lamp should go
out and the BAS is operational.
If the BAS/ESP malfunction indicator lamp comes on
permanently while the engine is running, a malfunction
has been detected in either system. As a result, it is
possible that now only partial engine output will be
available. If the BAS malfunctions, the brake system
functions in the usual manner, but without BAS.
With the ABS malfunctioning, the BAS is also switched
off. Both malfunction indicator lamps come on with the
engine running.
If the BAS/ESP malfunction indicator lamp stays
illuminated, have the BAS or ESP checked at your
authorized Mercedes-Benz Light Truck Center as soon
as possible.

Antilock brake system (ABS)
Warning!
In the case of an emergency brake maneuver keep
continuous full pressure on the brake pedal. In this
manner only can the ABS be most effective.
On slippery road surfaces, the ABS will respond even
with light brake pedal pressure because of the
increased likelihood of locking wheels. The pulsating
brake pedal can be an indication of hazardous road
conditions and functions as a reminder to take extra
care while driving.
Do not pump the brake pedal, rather use firm,
steady brake pedal pressure. Pumping the brake
pedal defeats the purpose for ABS and significantly
reduces braking effectiveness.
Important!
The ABS improves steering control of the vehicle during
hard braking maneuvers.
ABS control
The ABS malfunction indicator lamp - in the
instrument cluster comes on with the key in steering
lock position 2 and should go out with the engine
running.
The ABS prevents the wheels from locking up above a
vehicle speed of approximately 5 mph (8 km/h)
independent of road surface conditions.
At the instant one of the wheels is about to lock up, a
slight pulsation can be felt in the brake pedal,
indicating that the ABS is in the regulating mode. Keep
firm and steady pressure on the brake pedal while
experiencing the pulsation.
When the ABS malfunction indicator lamp - in the
instrument cluster comes on while the engine is
running, it indicates that the ABS has detected a
malfunction and has switched off. In this case, the brake
system functions in the usual manner, but without
antilock assistance.
Continuous steady brake pedal pressure results in
applying the advantages of the ABS, namely braking
power and ability to steer the vehicle.
With the ABS malfunctioning, the BAS, EBP, ESP and
4-ETS+ are also switched off. The malfunction indicator
lamps come on with the engine running.

If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the ABS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.
Notes:
To alert following vehicles to slippery road conditions
you discover, operate your hazard warning flashers as
appropriate.
Operating the vehicle on a single axle dynamometer
should only be done for briefly testing the brakes. To do
so, move selector lever to position “N”. The engine must
be shut off (key in steering lock position 0 or 1).
If the ABS malfunction indicator lamp stays illuminated,
have the system checked at your authorized
Mercedes-Benz Light Truck Center as soon as possible.
Warning!
LOW RANGE – ABS
ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or
the traction afforded. The ABS cannot prevent
accidents, including those resulting from excessive
speed in turns, following another vehicle too
closely, or aquaplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of an ABS equipped vehicle must never
be exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the
safety of others.
During off-road driving a special low range system for
the antilock brake system (ABS) is operational with
transmission in LOW RANGE mode, see page 211.
When applying the service brakes at speeds below
approximately 18 mph (30 km/h), the front wheels are
locked cyclically to shorten the braking distance (dig in
effect). This affects steering the vehicle.

Four-wheel electronic traction system (4-ETS+)
4-ETS+ Control
With the key in steering lock position 2, the yellow
4-ETS+ malfunction indicator lamp { and the 4-ETS+
warning lamp v come on and should go out when
the engine is running.
If the yellow 4-ETS+ malfunction indicator lamp {
comes on while the 4-ETS+ warning lamp v flashes,
the electronic traction system is being switched off
temporarily to prevent overheating of the drive wheel
brakes.
The 4-ETS+ improves vehicle’s ability to utilize available
traction, especially under slippery road conditions. The
brakes are applied to the spinning wheel and power is
transferred to the wheel(s) with traction.
If the 4-ETS+ malfunction indicator lamp { comes on
with the engine running, a malfunction has been
detected.
The 4-ETS+ warning lamp v, located in the
speedometer dial, starts to flash at any vehicle speed, as
soon as the tires lose traction and the wheels begin to
spin.
Have the 4-ETS+ checked at your authorized
Mercedes-Benz Light Truck Center as soon as possible.
With the ABS malfunctioning, the 4-ETS+ is also
switched off.
Important!
Caution!
If the 4-ETS+ warning lamp v flashes:
• during take-off, apply as little throttle as possible,
• while driving, ease up on the accelerator.
If the vehicle is towed with the front axle raised (see
towing the vehicle on page 255), or when testing the
parking brake on a brake test dynamometer, the engine
must be shut off (key in steering lock position 0 or 1).
Otherwise, the electronic traction system will
immediately be engaged and will apply the rear wheel
brakes.
Adapt your speed and driving to the prevailing road
conditions.

Note:
Electronic brake proportioning (EBP)
In winter operation, the maximum effectiveness of the
electronic traction system is only achieved with
Mercedes-Benz recommended M+S rated radial-ply tires
and/or snow chains.
The EBP enhances braking effectiveness by allowing the
rear brakes to supply a greater proportion of the braking
effort without a loss of vehicle stability.
If a warning tone sounds for five seconds and the
symbols É and - are displayed in the instrument
cluster, the system has detected a malfunction and is
switched off. Have the system checked immediately at
an authorized Mercedes-Benz Light Truck Center.
Failure to do so could result in an accident, since the
enhanced braking effect is not available when the
system is switched off.
LOW RANGE – 4-ETS+
During off-road driving a special low range system for
the four wheel electronic traction system (4-ETS+) is
operational with transmission in LOW RANGE mode,
see page 211.
If one or more tires lose traction while driving downhill
(accelerator released), the 4-ETS+ engages and the
warning lamp v, located in the speedometer dial,
starts to flash.
Note:
When the EBP is switched off, every time the engine is
started, a warning tone will sound for five seconds and
the symbols É and - will light up. In addition,
whenever the brakes are applied at speeds exceeding
25 mph (40 km/h), the warning tone sounds for five
seconds.

Electronic stability program (ESP)
Warning!
Important!
If the ESP warning lamp v flashes:
• During take-off apply as little throttle as possible.
• While driving ease up on the accelerator.
ESP cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded. The ESP cannot prevent
accidents, including those resulting from excessive
speed in turns, or aquaplaning. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities of an ESP equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety or
the safety of others.
• Adapt your speed and driving to the prevailing road
conditions.
• Do not switch off the ESP.
Caution!
If the vehicle is towed with the front axle raised (see
towing the vehicle on page 255), the engine must be
shut off (key in steering lock position 0 or 1). Otherwise,
the ESP will immediately be engaged and will apply the
rear wheel brakes.
The ESP enhances directional control and reduces
driving wheel spin of the vehicle under various driving
conditions.
Over-/understeering of the vehicle is counteracted by
applying brakes to the appropriate wheel to create a
countervailing vehicle movement. Engine torque is also
limited. The ESP warning lamp, located in the
speedometer dial, starts to flash when ESP is in
operation.
Notes:
The malfunction indicator lamp for the ESP is combined
with that of the BAS.
The yellow BAS/ESP malfunction indicator lamp ¿
in the instrument cluster and the yellow ESP warning
lamp v in the speedometer dial come on with the
key in steering lock position 2. They should go out with
the engine running.

If the BAS/ESP malfunction indicator lamp ¿ comes
on continuously with the engine running, a malfunction
has been detected in either system. Only partial engine
output will be available.
When testing the parking brake on a brake test
dynamometer, the engine must be shut off. Otherwise,
the ESP will immediately be engaged and will apply the
rear wheel brakes.
If the BAS malfunctions, the brake system functions in
the usual manner, but without BAS.
In winter operation, the maximum effectiveness of the
ESP is only achieved with Mercedes-Benz recommended
M+S rated radial-ply tires and/or snow chains.
If the BAS/ESP malfunction indicator lamp stays
illuminated, have the BAS or ESP checked at your
authorized Mercedes-Benz Light Truck Center as soon
as possible.
Synchronizing ESP
If the power supply was interrupted (battery
disconnected or empty), the BAS/ESP malfunction
indicator lamp may be illuminated with the engine
running.
With the ABS malfunctioning, the ESP is also switched
off.
Driving the vehicle with varied size tires will cause the
wheels to rotate at different speeds, therefore the ESP
may activate (yellow ESP warning lamp v in
speedometer dial comes on). For this reason, all wheels,
including the spare wheel, must have the same tire
outside diameter.
After driving off the BAS/ESP malfunction indicator
lamp should go out after approximately 110 - 220 yd
(100 - 200 m).

If one drive wheel loses traction and begins to spin, the
brake is applied until the wheel regains sufficient
traction.
LOW RANGE – ESP
During off-road driving a special low range system for
the electronic stability program (ESP) is operational
with transmission in LOW RANGE mode, see page 211.
Note:
In the LOW RANGE mode the electronic stability
program (ESP) operates in a traction improving fashion
specifically adapted for off-road driving. At speeds
below 27 mph (45 km/h) the ESP assists in over-/
understeering, thus improving vehicle tracking.
Avoid spinning of one drive wheel. This may cause
serious damage to the drive train which is not covered
by the Mercedes-Benz Limited Warranty.
The ESP warning lamp, located in the speedometer dial,
starts to flash at any vehicle speed as soon as the tires
lose traction and the wheels begin to spin.
To return to the enhanced vehicle stability offered by
ESP: press lower half of the switch (the ESP warning
lamp in the speedometer dial goes out).
Important!
If the ESP warning lamp flashes:
• during take-off, apply as little throttle as possible,
• while driving, ease up on the accelerator.

When the ABS malfunction indicator lamp in the
instrument cluster comes on while the engine is
running, it indicates that the ABS has detected a
malfunction and has switched off. In this case, the brake
system functions in the usual manner, but without
antilock assistance.
If the indicator lamp does not go out after starting the
engine, the adjustable steering column is not properly
locked.
For locking the adjustable telescoping steering column,
see page 70.
With the ABS malfunctioning, the BAS, ESP and 4-ETS+
are also switched off. Both malfunction indicator lamps
come on with the engine running.
AIRBAG OFF indicator lamp
The indicator lamp will light up for
approximately 6 seconds, extinguish, then
blink once, when you turn the key in
steering lock to position 1 or 2.
If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the ABS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.
The 7 indicator lamp stays lit as long as a
BabySmartTM compatible child seat is properly installed
on the front passenger seat. It indicates that the front
passenger airbag is switched off.

Low engine oil level warning lamp
224
Low engine coolant level warning
With the key in steering lock position 2, the
oil level warning lamp comes on and should
go out when the engine is running.
When the coolant level warning lamp comes
on while driving, then the coolant level has
dropped below the required level, or the
coolant temperature is in the red zone. If no leaks are
noticeable and the engine temperature does not
increase, continue to drive to the nearest service station
and have coolant added to the coolant system, see
page 234. If the engine temperature reaches the red
zone, move vehicle to an area which is in a safe distance
from the roadway and turn off the engine. Also see
coolant temperature gauge on page 81.
If the warning lamp does not go out after starting the
engine, or comes on with the engine running and at
operating temperature, the engine oil level has dropped
to approximately the minimum mark on the dipstick.
When this occurs, the warning lamp will first come on
intermittently and then stay on if the oil level drops
further.
If no oil leaks are noted, continue to drive to the nearest
service station where the engine oil should be topped to
the “full” mark on the dipstick with an approved oil.
The low engine coolant level warning should not be
ignored. Extended driving with the symbol displayed
may cause serious engine damage not covered by the
Mercedes-Benz Limited Warranty.
The low engine oil level warning light should not be
ignored. Extended driving with the light illuminated
could result in serious engine damage that is not
covered by the Mercedes-Benz Limited Warranty.
In cases of major or frequent minor coolant loss, have
the cooling system checked at your authorized
Mercedes-Benz Light Truck Center as soon as possible.
In addition to the warning lamp, the engine oil level
should be periodically checked with the dipstick or via
the oil level indicator in the odometer display field, for
example during a fuel stop, or before a long trip (see
engine oil level indicator on page 89 and checking
engine oil on page 233).
Notes:
Do not drive without coolant in the cooling system. The
engine will overheat causing major engine damage.
Monitor the coolant temperature gauge while driving.

Automatic transmission fluid level
234
Coolant level
The transmission has a permanent fill of automatic
transmission fluid.
Regular automatic transmission fluid level checks and
changes are not required. For this reason the dipstick is
omitted.
If you notice fluid leaks or gear shifting malfunctions,
have your authorized Mercedes-Benz Light Truck Center
check the transmission fluid level.
Engine oil consumption
Engine oil consumption checks should only be made
after the break-in period. During the break-in period,
higher oil consumption may be noticed and is normal.
Frequent driving at high engine speeds results in
increased consumption.
To check the coolant level, the vehicle must be parked
on level ground and the engine stopped.
Check coolant level only when coolant is cold.
The coolant level should reach the COLD LEVEL mark in
the reservoir.
Download from Www.Somanuals.com. All Manuals Search And Download.
Adding coolant
• Do not remove pressure cap on coolant
reservoir if engine temperature is above 194°F
(90°C). Allow engine to cool down before
removing cap. The coolant reservoir contains
hot fluid and is under pressure.
If coolant has to be added, a 50/50 mixture of water and
MB anticorrosion/antifreeze should be added.
After adding coolant, close cap until you hear it click a
few times.
• Using a rag, slowly open cap approximately
1/2 turn to relieve excess pressure. If opened
immediately, scalding hot fluid and steam will
be blown out under pressure.
The drain plugs for the cooling system are located on
the left and right side of the engine block directly above
the engine mounts and at the bottom of the radiator.
Anticorrosion/antifreeze mixture, see page 297.
• Do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which may
burn if it comes into contact with hot engine
parts.
Warning!
In order to avoid possible serious burns or injury:
• Use extreme caution when opening the hood if
there are any signs of steam or coolant leaking
from the cooling system, or if the coolant
temperature gauge indicates that the coolant is
overheated.

Tire replacement
Replace rims or tires with the same designation,
manufacturer and type as shown on the original part.
See your authorized Mercedes-Benz Light Truck Center
for further information.
Front and rear tires should be replaced in sets.
Furthermore – in the event of tire replacement – the
optional regular size spare wheel should be used on the
rear axle. Rims and tires must be of the correct size and
type. For dimensions, see technical data on page 288.
Warning!
We recommend that you break in new tires for
approximately 60 miles (100 km) at moderate speed.
Do not mix different tire construction types (i.e.
radial, bias, bias-belted) on your vehicle because
handling may be adversely affected and may result
in loss of control.
It is imperative that the wheel mounting bolts be
fastened to a tightening torque of 110 ft.lb. (150 Nm)
whenever wheels are mounted.
For rim and tire specifications, refer to technical data on
page 288.
See your authorized Mercedes-Benz Light Truck Center
for information on tested and recommended rims and
tires for summer and winter operation. They can also
offer advice concerning tire service and purchase.
Warning!
Worn, old tires can cause accidents. If the tire tread
is badly worn, or if the tires have sustained
damage, replace them.
When replacing rims, use only genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result in
the bolts loosening and possibly an accident.

Rotating wheels
Notes:
The wheels can be rotated according to the degree of
tire wear while retaining the same direction of travel.
Thoroughly clean the inner side of the wheels any time
you rotate the wheels or wash the vehicle underside.
Rotating, however, should be carried out as
The use of retread tires is not recommended. Retread
tires may adversely affect the handling characteristics
and safety of the vehicle.
recommended by the tire manufacturer, before the
characteristic tire wear pattern (shoulder wear on front
wheels and tread center wear on rear wheels) becomes
visible, as otherwise the driving properties deteriorate.
Dented or bent rims can cause tire pressure loss and
damage to the tire beads. For this reason, check rims for
damage at regular intervals. The rim flanges must be
checked for wear before a tire is mounted. Remove
burrs, if any.
Important!
Unidirectional tires must always be mounted with arrow
on tire sidewall pointing in direction of vehicle forward
movement.
Check and ensure proper tire inflation pressure after
rotating the wheels. For tire inflation pressure see
page 250.

Tire inflation pressure
Tire pressures listed for light loads are minimum values
offering high driving comfort. Increased inflation
pressures for heavy loads produce favorable handling
characteristics with lighter loads and are perfectly
permissible. The ride of the vehicle, however, will
become somewhat harder.
A table (see fuel filler flap) lists the tire inflation
pressures specified for Mercedes-Benz recommended
tires as well as for the varying operating conditions.
Important!
Tire temperature and pressure increase with the vehicle
speed. Tire pressure should therefore only be checked
and corrected on cold tires. Correct tire pressure in
warm tires only if pressure has dropped below the
pressure listed in the table and the respective operating
conditions are taken into consideration.
Tire pressure changes by approximately 1.5 psi (0.1 bar)
per 18°F (10°C) of air temperature change. Keep this in
mind when checking tire pressure inside a garage –
especially in the winter.
Example:
If garage temperature = approximately +68°F (+20°C)
and ambient temperature = approximately +32°F (0°C)
then the adjusted air pressure = specified air pressure
+3 psi (+0.2 bar).
An underinflated tire due to a slow leak (e.g. due to a
nail in the tire) may cause damage such as tread
separation, bulging etc.. Regular tire pressure checks
(including the spare tire) at intervals of no more than
14 days are therefore essential.
Download from Www.Somanuals.com. All Manuals Search And Download.
If a tire constantly loses air, it should be inspected for
damage.
Battery
Warning!
The spare tire should be checked periodically for
condition and inflation. Spare tire will age and become
worn over time even if never used, and thus should be
inspected and replaced when necessary.
Failure to follow these instructions can result in
severe injury or death.
Never lean over batteries while connecting, you
might get injured.
Warning!
Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush affected
area with water and seek medical help if necessary.
Do not overinflate tires. Overinflating tires can
result in sudden deflation (blowout) because they
are more likely to become punctured or damaged
by road debris, potholes etc.. Follow recommended
inflation pressures.
A battery will also produce hydrogen gas, which is
flammable and explosive. Keep flames or sparks
away from battery, avoid improper connection of
jumper cables, smoking etc..
Do not overload the tires by exceeding the specified
vehicle capacity weight (as indicated by the label
on the driver’s door latch post). Overloading the
tires can overheat them, possibly causing a
blowout.
Important!
Battery replacement information:
The maintenance-free battery is located in the engine
compartment.
The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time.

Therefore, we strongly recommend that you have the
battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than
approximately 200 miles (300 km) per month,
mostly for short distance trips, or if it is not used for
long periods of time.
Note:
After reconnecting the battery also set the clock in
instrument cluster (see page 80), set date in trip
computer (see page 83), resynchronize the sliding/pop-
up roof (see page 272), the Skyview Top (see page 273)
and the electronic stability program (ESP) (see
page 206).
Only charge a battery with a battery charger after the
battery has been disconnected from the vehicle’s
electrical circuit.
Battery recycling
Always disconnect the battery negative lead first and
connect last.
Batteries contain material that can harm the
environment with improper disposal.
When removing and connecting the battery, always
make sure that all electrical consumers are off and the
key is in steering lock position 0. The battery must
always be securely installed when the vehicle is in
operation. During removal and installation always
protect the disconnected battery positive (+) terminal
with the cover attached to the battery.
Large 12 Volt storage batteries contain lead.
Recycling of batteries is the preferred method of
disposal.
Many states require sellers of batteries to accept old
batteries for recycling.
While the engine is running the battery terminal clamps
must not be loosened or detached, otherwise the
generator and other electronic components would be
damaged.

Jump starting
Warning!
Important!
A discharged battery can freeze at approximately +14°F
(–10°C). In that case, it must be thawed out before
jumper cables are used. Attempting to jump start a
frozen battery can result in it exploding, causing
personal injury.
Failure to follow these directions will cause
damage to the electronic components, and can lead
to a battery explosion and severe injury or death.
Never lean over batteries while connecting or jump
starting, you might get injured.
Jumper cable specifications:
• Minimum cable cross-section of 25 mm2 or
Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush affected
area with water, and seek medical help if
necessary.
approximately 2 AWG
• Maximum length of 11.5 ft. (3.5 m).
If the battery is discharged, the engine should be started
with jumper cables and the (12 V) battery of another
vehicle.
A battery will also produce hydrogen gas, which is
flammable and very explosive. Keep flames or
sparks away from battery, avoid improper
connection of jumper cables, smoking etc..
Only use 12 V battery to jump start your vehicle. Jump
starting with more powerful battery could damage the
vehicle’s electrical systems, which will not be covered
by the Mercedes-Benz Limited Warranty.

To be certain to avoid additional damage to the vehicle
powertrain, however you should do the following:
Caution!
If the vehicle is towed with the front axle raised, the
engine must be shut off (key in steering lock position 1).
Otherwise, the 4-ETS+ may become engaged which may
cause loss of towing control. Switch off the tow-away
alarm (see page 36) as well as the ESP (see page 207).
• With damage to front axle, raise front axle. Remove
flexible drive shaft between rear axle and transfer
case
• With damage to rear axle, raise rear axle and tow
vehicle with wheel lift or dolly placed under front
wheels.
Warning!
With the engine not running, there is no power
assistance for the braking and steering systems. In
this case, it is important to keep in mind that a
considerably higher degree of effort is necessary to
brake and steer the vehicle.

Stranded vehicle
Freeing a stranded vehicle, on which the wheels are dug
into sand or mud, should be done with the greatest of
care, especially if the vehicle is heavily loaded.
Avoid pulling the vehicle jerkily or diagonally, since it
could result in damage to the chassis alignment.
Never try to free a vehicle that is still coupled to a
trailer.
If possible, a vehicle equipped with trailer hitch receiver
should be pulled backward in its own previously made
tracks.
In the case of power failure the transmission selector
lever can be manually unlocked, e.g. to tow the vehicle.
To do so, insert a pin (1), e.g. ball point pen, into the
covered opening below the position “D” of the shift
pattern. While pushing the pin down, move selector
lever from position “P”.
After removal of the pin from the opening, the cover will
not close fully. Only after moving the selector lever to
positions “D+” and “D–” does the cover return to its
closed position.

Roof rack
Use only those roof racks approved by Mercedes-Benz.
Follow manufacturer’s installation instructions. They
mount to the roof rails and do not require additional
supports (e.g. suction cups or legs). Such supports may
lead to marring of the paint or denting the roof. For
further information inquire at your Mercedes-Benz
Light Truck Center.
Take into consideration that when the roof rack is
loaded, the handling characteristics are different from
those when operating the vehicles without the roof rack
loaded.

Cleaning and care of the vehicle
278
Cleaning and care of the vehicle
More frequent washings are necessary to deal with
unfavorable conditions; for example, near the ocean, in
industrial areas (smoke, exhaust emissions), or during
winter operation.
Warning!
Many cleaning products can be hazardous. Some
are poisonous, others are flammable. Always follow
the instructions on the particular container.
Always open your vehicle’s doors or windows when
cleaning the inside.
You should check your vehicle from time to time for
stone chipping or other damage. Any damage should be
repaired as soon as possible to prevent the start of
corrosion.
Never use fluids or solvents that are not designed
for cleaning your vehicle.
In doing so, do not neglect the underside of the vehicle.
A prerequisite for a thorough check is a washing of the
underbody followed by a thorough inspection. Damaged
areas need to be reundercoated.
In operation, your vehicle is subjected to varying
external influences which, if gone unchecked, can
attack the paintwork as well as the underbody and
cause lasting damage.
Your vehicle has been treated at the factory with a wax-
base rustproofing in the body cavities which will last for
the lifetime of the vehicle. Post-production treatment is
neither necessary nor recommended by Mercedes-Benz
because of the possibility of incompatibility between
materials used in the production process and others
applied later.
Such damage is caused not only by extreme and varying
climatic conditions, but also by air polution, road salt,
tar, gravel and stone chipping. Grease and oil, fuel,
coolant, brake fluid, bird droppings, insects, tree resins
etc. should be removed immediately to avoid paint
damage. Frequent washing reduces and/or eliminates
the aggressiveness and potency of the above adverse
influences.
We have selected car-care products and compiled
recommendations which are specially matched to our
vehicles and which always reflect the latest technology.
You can obtain Mercedes-Benz approved car-care
products at your authorized Mercedes-Benz Light Truck
Center.
Download from Www.Somanuals.com. All Manuals Search And Download.
Scratches, corrosive deposits, corrosion or damage due
to negligent or incorrect care cannot always be removed
or repaired with the car-care products recommended
here. In such cases it is best to seek aid at your
authorized Mercedes-Benz Light Truck Center.
Tar stains
Quickly remove tar stains before they dry and become
more difficult to remove. A tar remover is
recommended.
The following topics deal with the cleaning and care of
your vehicle and give important “how-to” information as
well as references to Mercedes-Benz approved car-care
products.
Paintwork, painted body components
Mercedes-Benz approved Paint Care should be applied
when water drops on the paint surface do not “bead up”,
normally in 3 to 5 months, depending on climate and
washing detergent used.
Additional information can be found in the booklet titled
“Vehicle Care Guide”.
Mercedes-Benz approved Paint Cleaner should be
applied if paint surface shows signs of dirt embedding
(i.e. loss of gloss).
Power washer
When using a power washer for cleaning the vehicle
always observe manufacturers’ operating instructions.
Do not apply any of these products or wax if your
vehicle is parked in the sun or if the hood is still hot.
Use the appropriate MB-Touch-Up Stick for quick and
provisional repairs of minor paint damage (i.e. chips
from stones, vehicle doors etc.).
Caution!
Never use a round nozzle to power wash tires. The
intense jet of water can result in damage to the tire.
Always replace a damaged tire.
Always keep the jet of water moving across the surface.
Do not aim directly at electrical parts, electrical
connectors, seals, or other rubber parts.

Cleaning and care of the vehicle
Engine cleaning
280
Due to the width of the vehicle, prior to running the
vehicle through an automatic car wash, fold back the
outside mirrors to prevent them from getting damaged.
Prior to cleaning the engine compartment make sure to
protect electrical components and connectors from the
intrusion of water and cleaning agents.
In the winter, thoroughly remove all traces of road salt
as soon as possible.
Corrosion protection, such as MB Anticorrosion Wax
should be applied to the engine compartment after
every engine cleaning. Before applying, all control
linkage bushings and joints should be lubricated. The
poly-V-belt and all pulleys should be protected from any
wax.
When washing the underbody, do not forget to clean the
inner sides of the wheels.
Ornamental moldings
For regular cleaning and care of very dirty chrome-
plated parts, use a chrome cleaner.
Vehicle washing
Do not use hot water or wash your vehicle in direct
sunlight. Use only a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo.
Headlamps, taillamps, turn signal lenses
Use a mild car wash detergent, such as Mercedes-Benz
approved Car Shampoo, with plenty of water.
Thoroughly spray the vehicle with a diffused jet of
water. Direct only a very weak spray towards the
ventilation intake. Use plenty of water and rinse the
sponge and chamois frequently.
To prevent scratches, never apply strong force and use
only a soft, non-scratchy cloth when cleaning the lenses.
Do not attempt to wipe dirty lenses with a dry cloth or
sponge.
Rinse with clear water and thoroughly wipe dry with a
chamois. Do not allow cleaning agents to dry on the
finish.

Window cleaning
Light alloy wheels
Use a window cleaning solution on all glass surfaces. An
automotive glass cleaner is recommended.
Mercedes-Benz approved Wheel Care should be used for
regular cleaning of the light alloy wheels.
If possible, clean wheels once a week with
Mercedes-Benz approved Wheel Care, using a soft
bristle brush and a strong spray of water.
Note:
For safety reasons, switch off wipers and remove key
from steering lock before cleaning the windshield,
otherwise the wiper motor can suddenly turn on and
cause injury.
Follow instructions on container.
Note:
Use only acid-free cleaning materials. The acid could
lead to corrosion or may damage the clear coat.
Wiper blades
Clean the wiper blade rubbers with a clean cloth and
detergent solution.
Instrument cluster
Use a gentle dishwashing detergent or mild detergent
for delicate fabrics as a washing solution. Wipe with a
cloth moistened in lukewarm solution. Do not use
scouring agents.
Note:
For safety reasons, switch off wipers and remove key
from steering lock before cleaning the wiper blades,
otherwise the wiper motor can suddenly turn on and
cause injury.
Steering wheel and gear selector lever
Wipe with a damp cloth and dry thoroughly or clean
with Mercedes-Benz approved Leather Care.

Upholstery
Use a gentle dishwashing detergent or mild detergent
for delicate fabrics as a washing solution. Wipe with a
cloth moistened in lukewarm solution. Do not use
scouring agents.
Using aftermarket seat covers or wearing clothing that
have the tendency to give off coloring (e.g. when wet
etc.) may cause the upholstery to become permanently
discolored. By lining the seats with a proper
intermediate cover, contact-discoloration will be
prevented.
Seat belts
Leather Upholstery
The webbing must not be treated with chemical
cleaning agents. Use only clear, lukewarm water and
soap. Do not dry the webbing at temperatures above
176°F (80°C) or in direct sunlight.
Wipe leather upholstery with a damp cloth and dry
thoroughly or clean with Mercedes-Benz approved
Leather Care. Exercise particular care when cleaning
perforated leather as its underside should not become
wet.
Warning!
Cloth Upholstery
Clean with soft bristle brush, or use a dry-shampoo
cleaner in case of excessive dirt.
Do not bleach or dye seat belts as this may severely
weaken them. In a crash they may not be able to
provide adequate protection.
Hard plastic trim items
Headliner
Pour Mercedes-Benz approved Interior Care onto soft
lint-free cloth and apply with light pressure.
Clean with soft bristle brush, or use a dry-shampoo
cleaner in case of excessive dirt.
Plastic and rubber parts
Do not use oil or wax on these parts.

Engine oils
294
Air conditioner refrigerant
R-134a (HFC) refrigerant and special PAG lubricating oil
is used in the air conditioner system.
Engine oils are specifically tested for their suitability in
our engines. Therefore, use only engine oils
recommended by Mercedes-Benz. Information on
recommended brands is available at your authorized
Mercedes-Benz Light Truck Center.
Never use R-12 (CFC) or mineral-based lubricating oil,
otherwise damage to the system will occur.
Please follow Service Booklet recommendations for
scheduled oil changes. Failure to do so could result in
engine damage not covered by the Mercedes-Benz
Limited Warranty.
Brake fluid
During vehicle operation, the boiling point of the brake
fluid is continuously reduced through the absorption of
moisture from the atmosphere. Under extremely hard
operating conditions, this moisture content can lead to
the formation of bubbles in the system thus reducing
the system’s efficiency.
Engine oil additives
Do not blend oil additives with engine oil. They may be
harmful to the engine operation.
The brake fluid must therefore be replaced every two
years, preferably in the spring.
Damage or malfunctions resulting from blending oil
additives are not covered by the Mercedes-Benz Limited
Warranty.
It is recommended to use only brake fluid approved by
Mercedes-Benz. Your authorized Mercedes-Benz Light
Truck Center will provide you with additional
information.

Premium unleaded gasoline
Caution!
Fuel requirements
Use only Premium unleaded meeting ASTM
standard D 439:
To maintain the engine’s durability and performance,
premium unleaded gasoline must be used. If premium
unleaded is not available and low octane fuel is used,
follow these precautions:
The octane number (posted at the pump) must be
91 min. It is an average of both the Research (R) octane
number and the Motor (M) octane number: [(R+M)/2].
This is also known as ANTI-KNOCK INDEX.
• have the fuel tank filled only partially with unleaded
regular and fill up with premium unleaded as soon
as possible,
Unleaded gasoline containing oxygenates such as
Ethanol, IPA, IBA and TBA can be used provided the
ratio of any one of these oxygenates to gasoline does not
exceed 10%, MTBE not to exceed 15%.
• avoid full throttle driving and abrupt acceleration,
The ratio of Methanol to gasoline must not exceed 3%
plus additional cosolvents.
• do not exceed an engine speed of 3000 rpm, if the
vehicle is loaded with a light load such as two
persons and no luggage,
Using mixtures of Ethanol and Methanol is not allowed.
Gasohol, which contains 10% Ethanol and 90% unleaded
gasoline, can be used.
• do not exceed 2/3 of maximum accelerator pedal
position, if the vehicle is fully loaded or operating in
mountainous terrain.
These blends must also meet all other fuel requirements
such as resistance to spark knock, boiling range, vapor
pressure etc..

Gasoline additives

Coolants
A major concern among engine manufacturers is carbon
build up caused by gasoline. Mercedes-Benz
The engine coolant is a mixture of water and
anticorrosion/antifreeze, which provides:
recommends the use of only quality gasoline containing
additives that prevent the build up of carbon deposits.
• corrosion protection,
• freeze protection,
After an extended period of using fuels without such
additives, carbon deposits can build up especially on the
intake valves and in the combustion area, leading to
engine performance problems such as:
• boiling protection (by increasing the boiling point).
The cooling system was filled at the factory with a
coolant providing freeze protection to approximately
-35°F (-37°C) and corrosion protection.
• warm-up hesitation,
• unstable idle,
• knocking/pinging,
• misfire,
If the antifreeze mixture is effective to -22°F (-30°C), the
boiling point of the coolant in the pressurized cooling
system is reached at approx. 266°F (130°C).
The coolant solution must be used year round to provide
the necessary corrosion protection and increase in the
boil-over protection. You should have it replaced every
3 years.
• power loss.
Do not blend other specific fuel additives with fuel.
They only result in unnecessary cost, and may be
harmful to the engine operation.
To provide the important corrosion protection, the
solution must be at least 45% anticorrosion/antifreeze
(equals a freeze protection to approx. - 22°F [-30°C]). If
you use a solution that is more than 55% anticorrosion/
antifreeze (freeze protection to approx. - 49°F [-45°C])-,
Damage or malfunctions resulting from poor fuel
quality or from blending specific fuel additives are not
covered by the Mercedes-Benz Limited Warranty.

the engine temperature will increase due to the lower
heat transfer capability of the solution. Therefore, do not
use more than this amount of anticorrosion/antifreeze.
Before the start of the winter season (or once a year in
the hot southern regions), you should have the
anticorrosion/antifreeze concentration checked. The
coolant is also regularly checked each time you bring
your vehicle to your authorized Mercedes-Benz Light
Truck Center for service.
If the coolant level is low, water and MB anticorrosion/
antifreeze should be used to bring it up to the proper
level (have cooling system checked for signs of leakage).
The water in the cooling system must meet minimum
requirements, which are usually satisfied by normal
drinking water. If your are not sure about the water
quality, consult your authorized Mercedes-Benz Light
Truck Center.

Your vehicle contains a number of aluminum parts. The
use of aluminum components in motor vehicle engines
necessitates that anticorrosion/antifreeze coolant used
in such engines be specifically formulated to protect the
aluminum parts. (Failure to use such anticorrosion/
antifreeze coolant will result in a significantly
shortened service life.)
Therefore the following product is strongly
recommended for use in your vehicle: Mercedes-Benz

Treadwear
This has been prepared as required of all manufactures
of passenger cars under Title 49, Code of U.S. Federal
Regulations, Part 575 pursuant to the “National Traffic
and Motor Vehicle Safety Act of 1966”.
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half
(1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends
upon the actual conditions of their use, however, and
may depart significantly from the norm due to
Uniform tire quality grading
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction
Tread wear 200 Traction AA
Temperature A
The traction grades, from highest to lowest are AA, A, B,
and C. Those grades represent the tire’s ability to stop
on wet pavement as measured under controlled
conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor
traction performance.
All passenger vehicle tires must conform to federal
safety requirements in addition to these grades.
Warning!
The traction grade assigned to this tire is based on
straight ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or
peak traction characteristics.

Temperature
Warning!
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of
The temperature grade for this tire is established
for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in
combination, can cause excessive heat build up
and possible tire failure.
performance which all passenger vehicle tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
