Warning!
If you feel a sudden significant vibration or
ride disturbance, or you suspect that
possible damage to your vehicle has
occurred, you should turn on the hazard
warning flashers, carefully slow down, and
drive with caution to an area which is a safe
distance from the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to
the nearest authorized Mercedes-Benz
Center or tire dealer for repairs.
Off-road driving increases strain on the
vehicle.
We recommend that you inspect the vehicle
for possible damage after each off-road trip.
Recognizing any damage and a subsequent
timely repair reduces the chance of a possible
breakdown or accident later on.
Proceed as follows:
R
Switch off the off-road driving program
(Y page 185) or the LOW RANGE mode
(Y page 142).
R
Switch off the DSR (Y page 182).
R
Set the differential locks to AUTO
(Y page 145).
R
Lower the vehicle back to a level suitable
for road conditions, e. g. highway/high-
speed level (Y page 186).
R
Clean all exterior lamps and check for
possible damage.
R
Clean the front and rear license plate.
R
Remove excessive dirt from tires, wheels,
wheel housings, and underbody.
For instance, after driving in mud, clean the
radiator, chassis, engine, brakes, and
wheels from extreme dirt using a strong jet
of water.
R
Check tires for possible damage.
R
Inspect vehicle underbody, oil pan, brake
hoses, etc., as well as vehicle underbody
for possible damage.
R
Check for brush or branches caught in the
underbody.
!
Brush or branches could increase the
possibility of a fire, as well as cut fuel and/
or brake lines, puncture rubber bellows of
the axles or drive shafts.
R
After continued operation in mud, sand,
water or other dirty conditions clean the
brake discs, wheels, brake pads and check
and clean axle joints.
R
Conduct a brake test.
