Mercedes-Benz GL-Class: Driving on sand
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.
Observe the following rules when driving on sand:
• select a higher vehicle level.
• avoid high engine speeds.
• select a shift range appropriate to the
terrain.
• drive quickly to overcome the rolling
resistance. Otherwise, the vehicle could dig
itself into the sand.
• drive in the tracks of other vehicles if
possible. Make sure that the ruts are not
too deep, that the sand is firm enough and
that your vehicle has sufficient ground
clearance.
