Checklist before driving off-road
Engine oil level: check the engine oil and
X
top it up if necessary.
When driving on steep gradients, the oil
level must be sufficiently high to ensure a
correct oil supply in the vehicle.
Wheels and tyres: check the tyre tread
X
depth and tyre pressure.
Check for damage and remove any foreign
X
objects, e.g. small stones, from the
wheels/tyres.
Replace any missing valve caps.
X
Replace dented or damaged wheels.
X
Wheels: dented or bent wheels can lead to
X
a loss of tyre pressure and damage to the
tyre bead. Before driving off-road, check
the wheels and replace them if necessary.
Checklist after driving off-road

driving off-road, have the vehicle checked

remove any foreign objects.
Clean the wheels, wheel arches and the

increase the risk of fire and can damage
fuel pipes, brake hoses or the rubber bel-
lows of the axle joints and propeller shafts.
After the trip, examine without fail the

entire undercarriage, wheels, tyres, brakes,
bodywork structure, steering, chassis and
exhaust system for damage.
