Recommended procedure
f Deactivate the Low Range off-road driving
program.
f Clean headlights and tail lights and check them
for signs of damage.
f Clean the front and rear lincense plates.
f Clean the tire tread with a jet of water and
remove any foreign objects.
f Clean wheels, wheel housings and the under-
body with a jet of water.
f Check whether the car has picked up plant
parts or branches.
These materials increase the risk of fire and
can damage fuel lines, brake hoses, boots of
the axle joints and drive shafts.
f After off-road driving, always check the entire
floor assembly, tires, body structure, steering
system, running gear and exhaust system for
signs of damage.
f After driving for an extended period through
mud, sand, water or substances with a similar
soiling effect, check the brake discs, brake
pads, wheels and axle joints and have them
cleaned.
f If you experience severe vibrations after
driving off road, check the wheels for foreign
substances.
These substances can produce an imbalance
which might be responsible for the vibrations.
Removing these deposits may remedy the
problem.
Uphill driving
Danger!
Danger of serious personal injury or death
and risk of damage if the vehicle should
overturn.
f Do not turn around when driving uphill.
f If it is not possible to climb a gradient, the car
must be backed down in reverse gear.
f Do not drive over embankments or slopes at
steep diagonal angles.
f If the vehicle starts to tilt, immediately steer in
the direction of the tilt (line of slope).
f When driving uphill, never let the vehicle roll
backward when in idle or not in gear.
Exclusive use of the footbrake is too risky in
such situations.
