Mercedes-Benz 2011 GL-Class Automobile User Manual


 
G
Warning!
Please be aware that by raising the vehicle
level, the center of gravity also rises.
Therefore, always ensure that the vehicle
level is as low as possible. With higher ride
height the ESP
®
may activate earlier in certain
situations.
G
Warning!
Do not reduce the tire inflation pressure
before driving through sand. However, if you
do so, remember to correct the tire inflation
pressure before continuing your trip. Driving
with reduced tire inflation pressure increases
the risk of losing control of the vehicle and
rolling over.
General information
Read this section before driving your vehicle
off-road. Practice by traveling over more
gentle off-road terrain first.
Familiarize yourself with the characteristics
of your vehicle and the gear change process
before driving through difficult terrain.
The following driving systems are specially
adapted to off-road driving:
R

(Y page 203)
Observe the following notes:
R
stop your vehicle and, if necessary, select
the off-road drive program (Y page 204) or
the LOW RANGE off-road gear
(Y page 157) before driving off-road.
R
select a vehicle level that is suitable for the
terrain. Make sure there is always sufficient
ground clearance to prevent damage to the
vehicle.
R
activate the differential lock if necessary.
R
make sure that items of luggage and cargo
are stowed safely and are well secured
(Y page 268).
R
always keep the engine running and in gear
when driving on a downhill gradient.
Activate DSR (Y page 203).
R
always keep the doors, tailgate, windows
and the tilt/sliding sunroof closed while the
vehicle is in motion.
R
adapt the speed to suit the terrain
conditions. The more uneven, worn or
steeper the terrain is, the slower you should
drive.
R
drive slowly and at an even speed through
the water. Ensure that a bow wave does not
form as you drive.
R
drive with extreme care on unfamiliar off-
road routes where visibility is poor. For
safety reasons, get out of the vehicle first
and survey the off-road route.
R
look out for obstacles, such as rocks, holes,
tree stumps and furrows.
R
check the depth of water before fording
rivers and streams.
R
do not stop in water and do not switch the
engine off.
R
drive quickly on sand to overcome the
rolling resistance. Otherwise, the vehicle
could dig itself into the sand.
R
do not jump with the vehicle. This
interrupts the vehicle's traction.
R
always keep the engine running and in gear
when driving on slopes.
R
do not shift the automatic transmission to
transmission position N.
