Off-Road driving
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.
Please read this chapter carefully before you begin
off-road travel.
Special driving features are available for specific kinds
of operation:
•LOW RANGE mode, see page 227
•LOW RANGE - ABS, see page 220
•LOW RANGE - 4-ETS+, see page 222
•LOW RANGE - ESP, see page 226
Engage the LOW RANGE mode before driving under
off-road conditions. For switching LOW RANGE mode on
and off see page 227.
Fasten items being carried as securely as possible, see
page 154.
We recommend to keep doors, liftgate, windows, and
roof closed whenever driving in off-road mode.Important!
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.
Be especially careful when driving in unknown
territory. Eventually get out of the vehicle and scout the
path you intend to take.
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.
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.

213 Driving instructions
Te ch n i c a l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index At very steep inclines, not manageable with selector
lever in position “1”, switch transfer case to LOW
RANGE, see page 227 for instructions on how to engage
LOW RANGE.
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.
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.
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.Parking
Wa r n i n g !
To reduce the risk of personal injury, or damage to
the vehicle powertrain, as a result of vehicle/trailer
movement, always:1. Keep right foot on brake pedal.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”.7. On inclines turn front wheels towards the road
curb.

Cleaning and care of the vehicle
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.
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.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.
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.
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.
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 your authorized Mercedes-Benz Light Truck
Center.
Wa r n i n g !
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.Never use fluids or solvents that are not designed
for cleaning your vehicle.
