205 Operation
Driving instructions
Special driving features for off-road
driving
The following driving features are available
for specific kind of operation:
LOW RANGE mode (
page 127)
LOW RANGE – ABS (
page 77)
LOW RANGE – 4-ETS (
page 80)
LOW RANGE – ESP (
page 81)
Off-road driving rules
Engage the LOW RANGE mode before driv-
ing under off-road conditions
(
page 127).
Fasten items being carried as securely as
possible (
page 160).Checklist before off-road driving
Engine oil level
Check the engine oil level
(page 224). The display
OIL i.O
must appear via display in the speed-
ometer.
Only then can the vehicle obtain a trou-
ble-free oil supply, even on steep gradi-
ents.
iWe recommend keeping doors, liftgate,
windows, and tilt / sliding sunroof*
closed whenever driving in off-road
mode.
!Observe the following during off-road
driving:
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 and ruts.
Be especially careful when driving
in unknown territory. It may be nec-
essary to get out of the vehicle and
scout the path you intend to take.
Before driving through water, deter-
mine is depth.
Do not stop vehicle while immersed
in water, and do not shut off the
engine.
In sandy soil, please drive at a
steady speed as allowed by condi-
tions. This helps overcome the vehi-
cle rolling resistance and reduces
the likelihood of the vehicle sinking
into the ground.
Do not initiate jumps with the vehi-
cle. It interrupts the forward mo-
mentum of the vehicle.
Always drive onto slopes with the
the engine running and the vehicle
in gear.

215 Operation
Driving instructions
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 re-
duces the chance of engine overload-
ing and / or overheating.
On very steep inclines, not manageable
with gear selector lever in position1,
switch transfer case to LOW RANGE
mode (
page 127).
When going down a long hill, shift into
a lower gear and use the engine’s brak-
ing effect.
Avoid riding the brakes, thus overheat-
ing the vehicle and trailer brakes.
If the engine coolant rises to an ex-
tremely high temperature (coolant tem-
perature needle approaching the red
zone) when the air conditioning is on,
turn off the air conditioning system.
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 re-
turn to your lane.
Passenger compartmentWarning!
G
Always fasten items being carried as secure-
ly as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and cause injury
to vehicle occupants unless the items are
securely fastened in the vehicle.
The rear cargo compartment is the preferred
place to carry objects. Always use the parti-
tion net when transporting cargo. Partition
net cannot secure hard or heavy objects. Al-
ways fasten items being carried as securely
as possible using the cargo tie-down rings in
the cargo floor area and fastening materials.

240 OperationVehicle careCleaning and care of the vehicle
While in operation, even while parked, your
vehicle is subjected to varying external in-
fluences which, if gone unchecked, can at-
tack the paintwork as well as the
underbody and cause lasting damage.Such damage is caused not only by ex-
treme and varying climatic conditions, but
also by:
Air pollution
Road salt
Tar
Gravel and stone chipping
To avoid paint damage, you should imme-
diately remove:
Grease and oil
Fuel
Coolant
Brake fluid
Bird droppings
Insects
Tree resins, etc.
Frequent washing reduces and / or elimi-
nates the aggressiveness and potency of
the above adverse influences.More frequent washings are necessary to
deal with unfavorable conditions:
near the ocean
in industrial areas (smoke, exhaust
emissions)
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 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 facto-
ry 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 ap-
plied later.
Warning!
G
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the partic-
ular container. Always open your vehicle’s
doors or windows when cleaning the inside.
Never use fluids or solvents that are not de-
signed for cleaning your vehicle.

290 Practical hintsBattery
Batteries contain materials that can harm
the environment if disposed of improperly.
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.
iThe following procedures must be car-
ried out following any interruption of
battery power (e.g. due to reconnec-
tion):
Set the clock (
page 119).
Set the date in trip computer
(page 189).
Calibrate the compass
(page 191).
Resynchronize the ESP
(page 252).
Resynchronize side power windows
(page 148).
Resynchronize tilt / sliding
sunroof*(
page 152).
