Mercedes-Benz GL-Class: Checklist after driving off-road
WARNING
If you notice sudden significant vibrations or
unusual handling performance or if you
suspect that damage has occurred to the
vehicle, you should activate the hazard
warning lamps, gently reduce speed and
carefully head for an area that is located at a
safe distance from the road.
Check the tires and the underside of the
vehicle for damage. If the vehicle seems
unsafe, have the vehicle towed away to the
nearest Mercedes-Benz Center or tire dealer
to be repaired.
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.
► Deactivate the off-road drive program or the LOW RANGE off-road
gear.
► Deactivate DSR.
► Set the differential lock setting to AUTO
on
the selector wheel.
► Lower the vehicle level again to a level
suitable to the road conditions, e.g. to the
highway/high-speed level.
► Clean the headlamps and rear lights and
check for damage.
► Clean the front and rear license plates.
► Clean wheels/tires, wheel mounting and
underbody with a water jet, check them for
foreign objects and damage and rectify this
as required.
► After the trip, examine without fail the
entire undercarriage, wheels, tires, brakes,
bodywork structure, steering, chassis and
exhaust system for damage.
► 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.
► 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.
► 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.
► Test the brakes.
Checklist before driving off-road

and

The vehicle can only guarantee a smooth

sufficient level of engine oil ...
