Checklist before off-road driving
Engine oil level
ț Check the engine oil level with the oil
dipstick (
page 380).
Only with a proper oil level 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 whenever driving
off-road.
ț Adjust vehicle speed to condition of terrain.
The more uneven, rutty and steeper the ter-
rain, 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 un-
known territory. It may be necessary to get
out of the vehicle and scout the path you in-
tend to take.
ț Watch out for obstacles, such as rocks,
holes, tree stumps and ruts.
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 al-
lowed 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 onto slopes with the engine
running and the vehicle in gear.
ț Do not shift automatic transmission to
position N.
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 395) before continuing
your trip. Driving with reduced tire inflation
pressure increases the risk of losing control
of the vehicle and rolling over.
!
If the engine oil level warning lamp
(
page 473) comes on while driving, stop the
vehicle in a safe location or as soon at is safe to
do so. Check the engine oil level (
page 380).
The engine oil level warnings should not be
ignored. Extended driving with the symbol
displayed could result in serious engine damage
that is not covered by the Mercedes-Benz
Limited Warranty.
