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:
ț
Keep doors, tailgate, windows, and
tilt/sliding sunroof closed.
ț
Switch cruise control off.
ț
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.
ț
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.
ț
Watch out for obstacles, such as rocks,
holes, tree stumps, and ruts.
ț
Avoid excessive engine speeds – drive at
moderate engine speeds (max. 3000 rpm).
ț
Before driving through water, determine its
depth.
ț
Do not stop vehicle while immersed in water,
and do not shut off the engine.
ț
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.
ț
Do not initiate jumps with the vehicle. It
interrupts the forward momentum of the
vehicle.
ț
Always drive on slopes with the engine
running and the vehicle in gear.
ț
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 351) 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

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.
