Before driving off-road, check the wheels and
replace them if necessary.
Checklist after driving off-road
!
If you detect damage to the vehicle after
driving off-road, have the vehicle checked
immediately at a qualified specialist work-
shop.
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
If the Offroad or Offroad Plus drive program
is selected: select the Individual, Sport,
Comfort or Slippery drive program
(Y page 142).
X
Deactivate the LOW RANGE off-road gear
(Y page 217).
X
Deactivate DSR (Y page 214).
X
Lower the vehicle level again to a level suita-
ble to the road conditions, e.g. to the normal
level.
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, 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, body-
work 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.
