Avoid high engine speeds.

reduce the likelihood of the vehicle
sinking into the ground.
ț
Drive in tracks of other vehicles if they
are not too deep and if you have suffi-
cient clearance.

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 375) before continuing
your trip. Driving with reduced tire inflation
pressure increases the risk of losing control
of the vehicle and rolling over.
