Driving instructions
Standing water
To prevent water from entering the
passenger compartment or the engine
compartment if you must drive through
standing water, keep in mind

the maximum depth of the water may
not exceed 19 in (48 cm)

you must drive slowlyFor more information, see “Driving through
water” (
page 257).
Passenger compartment
!Do not drive through flooded areas or water
of unknown depth. Before driving through water,
determine its depth. Never accelerate before
driving into water. The bow wave could force
water into the engine and auxiliary equipment,
thus damaging them.
If you must drive through standing water, drive
slowly to prevent water from entering the
passenger compartment or the engine
compartment. Water in these areas could cause

damage to electrical components

wiring of the engine or transmission
or could result

in water being ingested by the engine
through the air intake, causing severe
internal engine damage.
Any such damage is not covered by the
Mercedes-Benz Limited Warranty.
Warning!G
Always fasten items being carried as
securely as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehi cle, and cause injury
to vehicle occupants unless the items are
securely fastened in the vehicle.
The rear cargo compartm ent is the preferred
place to carry objects. Always use cargo
tie-down rings, and if so equipped, always
use partition net* when transporting cargo.
The partition net* cannot secure hard or
heavy objects. Always fasten items being
carried as securely as possible using the
cargo tie-down rings in the cargo compart-
ment floor and fastening materials.
Do not load items on the roof. It may cause
instability during so me maneuvers which
could result in an acci dent. This vehicle is
not intended to carry items on its roof. Thus
roof rails and roof mounted ski or bike
holders must not be used.

Driving instructions
Off-road driving
Read this chapter carefully before you
begin off-road travel.
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. Special driving features for off-road
driving
The following driving features are available
for specific kind of operation:

ABS (page 87)

ESP® (page 91)

4-ETS (page 90)

Differential lock (page 173)

Transfer case (page 170)
Off-road driving rules
Engage the transfer case in position
LOW before driving under off-road
conditions (
page 170).
If necessary activate differential locks
(
page 175).
The ABS, BAS and ESP
® are switched
off automatically when the differential
locks are activated.
Fasten items being carried as securely
as possible (
page 208).
Warning!G
Do not load items on the roof. It may cause
instability during so me maneuvers which
could result in an accident.
Drive slowly in unkn own terrain. This will
make it easier to recognize unexpected
obstacles and avoid damage to the vehicle.
To help avoid the vehicle rolling over, never
turn it around on steep inclines. If the vehi-
cle cannot complete the attempted climb,
back it down in reverse gear.
Do not drive along the side of a slope. The
vehicle might otherwise 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).
Never let the vehicle roll backwards in idle.
You may lose control of the vehicle if you
use only the brake. For information on
driving downhill, see “Driving downhill”
(
page 257).
Warning!G
Sand, dirt, mud and other material having
friction property can cause exceptional wear
and tear as well as brake failure.
Have the brakes checked for dirt build-up
and cleaned. There is otherwise a risk that
full braking power may not be available in an
emergency.

Checklist before off-road driving
Engine oil level

Check the engine oil level with the
control system (
page 270). The
message
Engine oil level OK must
appear in the multifunction display.
Only then can the vehicle obtain a
trouble-free oil supply, even on steep
gradients.
!Observe the following during off-road
driving:

Keep doors, tailgate, windows, and
tilt/sliding sunroof closed.

Switch cruise control off.

Adjust vehicle speed to condition of terrain.
The more uneven, rutty, and steeper the
terrain, the lower the speed should be. Drive
through water slowly at an even speed,
avoiding a bow wave.

Be especially careful when driving in
unknown territory. It may be necessary to
get out of the vehicle and scout the path you
intend to take.

Watch out for obstacles, such as rocks,
holes, tree stumps, and ruts.

Avoid excessive engine speeds – drive at
moderate engine speeds (max. 3 000 rpm).

Before driving through water, determine its
depth.

Do not stop vehicle while immersed in water,
and do not shut off the engine.

In sandy soil, drive at a steady speed as
allowed by conditions. This helps overcome
the vehicle rolling resistance and reduces
the likelihood of the vehicle sinking into the
ground.

Do not initiate jumps with the vehicle. It
interrupts the forward momentum of the
vehicle.

Always drive on slopes with the engine
running and the vehicle in gear.

Inspect the vehicle for possible damage after
each off-road trip.
Warning!G
Do not reduce the tire inflation pressure
before driving through sand. However, if you
do so, remember to correct the tire inflation
pressure (
page 288) before continuing
your trip. Driving with reduced tire inflation
pressure increases the risk of losing control
of the vehicle and rolling over.
!If a engine oil level warning message
(
page 349) appears in the multifunction
display while driving, stop the vehicle in a safe
location or as soon at is safe to do so. Check the
engine oil level (
page 270).
The engine oil level warning messages should
not be ignored. Extended driving with the
message displayed could result in serious engine
damage that is not covered by the
Mercedes-Benz Limited Warranty.

Operation
Vehicle care
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 corrosion.
In doing so, do not neglect the underbody
of the vehicle. A prerequisite for a thor-
ough check is a washing of the underbody
followed by a thorough inspection. Dam-
aged areas need to be re-undercoated.
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.
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 an authorized
Mercedes-Benz Light Truck Center.
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 an
authorized Mercedes-Benz Light Truck
Center.
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 ap proved car-care
products. Power washer
Tar stains
Quickly remove tar stains before they dry
and become more difficult to remove. A tar
remover is recommended.
!Follow the instructions provided by the
power washer manufacturer on maintaining a
distance between the vehicle and the nozzle of
the power washer.
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 direct ly at electrical parts,
electrical connectors, sensors, seals, or other
rubber parts.
