!
Check that the ruts are not too deep and
your vehicle's clearance is sufficient. Otherwise:
your vehicle may be damaged
the underbody of the vehicle may come in
contact with the ground and you may get
stuck
Avoid high engine speeds.
Shift automatic transmission to
position 1 ( page 192).
Drive next to the ruts rather than
through them if at all possible.
If the ruts are too deep to drive in, drive
with one side of the vehicle on the
grassy center strip if the route permits.
Returning from off-road driving
Warning!
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
tion to an area which is a safe distance from
the roadway.
Inspect the tires and under the vehicle for
possible damage. If the vehicle or tires ap-
pear unsafe, have it towed to the nearest
Mercedes-Benz Light Truck Center or tire
dealer for repairs.
Damage to the vehicle may influence driving
comfort and pose the risk of accident to you
and other drivers.
Driving instructions
Off-road driving increases strain on the
vehicle.
G
We recommend that you inspect the vehi-
cle for possible damage after each off-road
trip. Recognizing any damage and a subse-
quent timely repair reduces the chance of
a possible breakdown or accident later on.
Proceed as follows:
Switch off the off-road driving program
( page 253).
Switch off the DSR ( page 250).
Vehicles with air suspension program*:
Lower the vehicle back to a level
suitable for road conditions, e.g. High-
way/High-speed level ( page 255).
Clean all exterior lamps and check for
possible damage.
Clean the front and rear license plate.
