If the vehicle was exposed to a significant
magnetic zone, such as high voltage power
lines, the compass may have to be calibrat-
ed.
To calibrate the compass correctly, ob-
serve the following:


Calibrate the compass in an area free
of steel superstructures and power
lines.


Switch off all electrical consumers (e.g.
exterior lamps, climate control, rear
window defroster etc.).


Do not open or close the tilt / sliding
sunroof.


Close doors and liftgate.

Start and run the engine.

Press MODE2 (
page 189) repeat-
edly until the compass display appears
in the trip computer display3.

Press RESET1 and afterwards press
MODE2.
In the display appears
CAL–
.

Press and hold RESET1 for approxi-
mately two seconds.
The calibration mode is activated and
the display shows
CAL
.

Drive without interruption two full cir-
cles at a speed between 3 mph
(5 km / h) and 7 mph (10 km / h).
The message

goes out after a short
time. The calibration is now complete.

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.

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.

Warning!
G
Failure to follow these instructions can
result in severe injury or death.
Observe all safety instructions and precau-
tions when handling automotive batteries
(page 228).
Never lean over batteries while connecting,
you might get injured.
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.
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.
!Never loosen or detach battery termi-
nal clamps while the engine is running
or the key is in the steering lock. Other-
wise the alternator and other electronic
components could be severely dam-
aged.
Have the battery checked regularly by
an authorized Mercedes-Benz Light
Truck Center.
Refer to Maintenance Booklet for main-
tenance intervals or contact an autho-
rized Mercedes-Benz Light Truck
Center for further information.Warning!
G
Do not place metal objects on the battery as
this could result in a short circuit.
Use leak-proof battery only to avoid the risk
of acid burns in the event of an accident.

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).
