Notes on driving when there is water on the road
Water which has entered the vehicle can damage
the engine, electrics and transmission.
Water can also enter the air intake fitting of the
engine and cause engine damage.
Observe the following if you must drive through
water:
R
The water, when calm, may only reach the
lower edge of the front bumper.
R
Drive at walking pace at most; water can other-
wise enter the vehicle interior or engine com-
partment.
R
Vehicles traveling in front, or oncoming vehi-
cles, can create waves which may exceed the
maximum permissible height of the water.
The braking effect of the brakes is reduced after
fording. Brake carefully while paying attention to
the traffic conditions until braking power has been
fully restored.
After the vehicle has forded at maximum depth
several times, all oils in the major assemblies (front
axle differential, locking differential, manual trans-
mission/automatic transmission and transfer
case) must be replaced.
Rules for off-road fording
R
Observe the safety notes and general notes on
driving off-road.
R
Check the depth and characteristics of the
body of water before fording. The water, when
calm, may only reach the lower edge of the
front bumper.
R
The climate control system is switched off
(

page 101).
R
The stationary heater is switched off
(

R
After the vehicle has forded at maximum depth
several times, all oils in the major assemblies
(front axle differential, locking differential,
manual transmission/automatic transmission
and transfer case) must be replaced.
Check-list after driving off-road
Driving over rough terrain places greater demands
on your vehicle than normal road operation. Check
your vehicle after driving on rough terrain. This
allows you to detect damage promptly and reduce
the risk of an accident for yourself and other road
users. Clean your vehicle thoroughly before driving
on public roads.
If you find damage to the vehicle after off-road
driving, have the vehicle checked at a qualified
specialist workshop immediately.
Observe the following points after driving off-road,
on construction sites and before driving on public
roads:
R
Vehicles with DSR: deactivate DSR
(
/
page 150).
R
All-wheel drive vehicles with engine OM642 or
engine OM651: deactivate all-wheel drive
(
/
page 126).
R
Activate ESP
®
(
