Keep doors, tailgate, windows, and tilt/
sliding sunroof closed whenever driving
off-road.
R
Switch the cruise control off.
R
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.
R
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.
R
Watch out for obstacles, such as rocks,
holes, tree stumps and ruts.
R
Avoid excessive engine speeds – drive at
moderate engine speeds (max. 3 000
rpm).
R
Before driving through water, determine
its depth.
R
Do not stop vehicle while immersed in
water, and do not shut off the engine.
R
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.
R
Do not initiate jumps with the vehicle. It
interrupts the forward momentum of the
vehicle.
R
Always drive onto slopes with the engine
running and the vehicle in gear.
R
Do not shift automatic transmission into
neutral position N.
R
Inspect the vehicle for possible damage
after each off-road trip.
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.
