Checklist before driving off-road
X
Engine oil level: check the engine oil and
top it up if necessary.
X
Tyre-change tool kit: check that the jack
is working and make sure you have the
wheelbrace, a robust tow cable and a fold-
ing spade in the vehicle.
X
Wheels and tyres: check the tyre tread
depth and tyre pressure.
X
Check for damage and remove any foreign
objects, e.g. small stones, from the
wheels/tyres.
X
Replace any missing valve caps.
X
Replace dented or damaged wheels.
Checklist after driving off-road
Driving over rough terrain places greater
demands on your vehicle than driving on nor-
mal 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
Deactivate DSR (
Y
page 213).
X
Clean the headlamps and rear lights and
check for damage.
X
Clean the front and rear licence plates.
X
Clean the wheels/tyres with a water jet and
remove any foreign objects.
X
Clean the wheels, wheel arches 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 bel-
lows of the axle joints and propeller shafts.
X
After the trip, examine without fail the
entire undercarriage, wheels, tyres, 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 detect strong vibrations after off-road
travel, check for foreign objects in the
wheels and drive train and remove them if
necessary. Foreign objects can disturb the
balance and cause vibrations.
