X Engine oil level: check the engine oil level
and add oil if necessary.
Only then does the engine receive enough
oil when the vehicle is standing on a steep
incline.
X Tire-changing tool kit: check that the jack
is working and make sure you have the lug
wrench, a robust tow cable and a folding
spade in the vehicle.
X Wheels and tires: check the tire tread
depth and tire pressure.
X Check for damage and remove any foreign
objects, e.g. small stones, from the
wheels/tires.
X Replace any missing valve caps.
X Replace dented or damaged wheels.
X Carry a sound spare wheel.
Checklist after driving off-road
Driving over rough terrain places greater
demands on your vehicle than driving on
normal roads. After driving off-road, check
the vehicle. This allows you to detect damage
promptly and reduce the risk of an accident
to yourself and other road users.
X Shift the transfer case to HIGH
RANGE( Y page 199).
X Disengage the differential locks
(
Y page 201).
X Clean the headlamps and rear lights and
check for damage.
X Clean the front and rear license plates.
X Clean the wheels and tires with a water jet
and remove any foreign objects.
X Clean the wheels, tires, wheel housings and
the vehicle underside with a water jet;
check for any foreign objects and damage.
X Check whether twigs or other parts of
plants have become trapped. These
increase the risk of fire and can damage
fuel pipes, brake hoses or the rubber
bellows of the axle joints and propeller
shafts.
X After the trip, examine without fail the
entire undercarriage, wheels, tires, brakes,
bodywork structure, steering, chassis and
exhaust system for damage.
X After driving for extended periods across
sand, mud, gravel, water or in similarly dirty
conditions, have the brake discs, wheels,
brake pads/linings and axle joints checked
and cleaned.
X If you notice strong vibrations after off-road
driving, check for foreign objects in the
wheels and drive train and, if necessary,
remove them. Foreign objects can disturb
the balance and cause vibrations.
X Test the brakes.
Driving on sand
Observe the following rules when driving on
sand:
R

RANGE( Y page 199).
R
Avoid high engine speeds.
R Limit the shift range of the automatic
transmission according to the off-road
conditions.
R
Drive quickly to overcome the rolling
resistance. Otherwise, the vehicle could dig
itself into the sand.
R
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.
Tire ruts and gravel roads
