Driving instructions
Checklist before off-road driving
Engine oil level

Check the engine oil level
(page 229). The display
ENGINE OIL
LEVEL - OK
must appear in the multi-
function display.
Only then can the vehicle obtain a trou-
ble-free oil supply, even on steep gradi-
ents.
Tires


Check the tread depth and maintain
specified tire pressure (see tire pres-
sure label inside the fuel filler flap).


Check tires for possible damage and
remove foreign objects.


Replace missing valve caps.
iWhenever driving in off-road mode, we
recommend:

Keeping doors, tailgate, windows
and sliding/pop-up roof closed.


Switching cruise control off.
!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. Drive through wa-
ter slowly at an even speed, avoid-
ing a bow wave.


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.


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


Avoid excessive engine
speeds – drive at moderate engine
speeds (max. 3000 rpm).


Before driving through water, deter-
mine its depth.


Do not stop vehicle while immersed
in water, and do not shut off the en-
gine.


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 vehi-
cle. It interrupts the forward mo-
mentum of the vehicle.


Always drive on slopes with the en-
gine running and the vehicle in
gear.


Inspect the vehicle for possible
damage after each off-road trip.

216 OperationDriving instructionsRims

Dented or bent rims can cause tire
pressure loss and damage the tire
beads. For this reason, check and, if
necessary, change rims before driving
off-road.
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.Driving in steep terrain
Slope angle127°
236°

Comply with the warnings
(page 214) and rules for off-road
driving (
page 214).


Driving on embankments, slopes and
other steep inclines should only be
done straight up or downhill, i.e. in the
line of gravity. Maximum vehicle climb-
ing ability is a 80% grade.


Select gear range2 or1 on the auto-
matic transmission (
page 142).


Drive slowly.


Utilize the engine’s braking power
when descending a slope, observe the
engine speed (do not overrev the en-
gine). Apply the service brake as need-
ed.


Check the brakes after a lengthy down-
grade drive.
Traction in steep terrain
Be easy on the accelerator and watch for
continuous wheel traction when driving in
steep terrain.iThe 4-ETS helps greatly when starting
out on a steep incline when the front
wheels have then the tendency to slip
due to the weight shifting away the
front axle.The 4-ETS recognizes the sit-
uation and limits the torque for the
front wheels by braking them. Simulta-
neously the torque for the rear wheels
is provided.

220 OperationDriving instructionsReturning from off-road drivingOff-road driving increases strain on the ve-
hicle.
We recommend that you inspect the vehi-
cle for possible damage after each off-road
trip. Recognizing any damage and a subse-
quent timely repair reduces the chance of
a possible breakdown or accident later on.
Proceed as follows:


Switch the transfer case in position
HIGH (
page 145).


Disengage differential locks
(page 151).


Remove excessive dirt from tires,
wheels, wheel housings, and under-
body.
For instance, after driving in mud, clean
the radiator, chassis, engine, brakes,
and wheels from extreme dirt using a
strong jet of water.


Inspect frame, oil pan, brake hoses,
etc., as well as vehicle underbody for
possible damage.


Check tires for possible damage and
remove foreign objects. Clean all exte-
rior lamps and conduct a brake test.
Warning!
G
Never drive on pavement with activated dif-
ferential locks. Engaged front axle differen-
tial locks limits ability to move around
curves.
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
tion 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 ap-
pear unsafe, have it towed to the nearest
Mercedes-Benz Light Truck Center or tire
dealer for repairs.
Damage to the vehicle negatively influences
driving comfort and poses the risk of acci-
dent to you and other drivers.
