Off-road driving
Important safet ynotes G
WARNING
If you driv eonas teep incline at an angle or
turn on asteep incline, the vehicl ecoulds lip
sideways, tip and overturn. There is arisk of
an accident.
When driving on an incline, drive into the line of fall (upwards or downward sinastraight
line) and do not turn. G
WARNING
Flammable materia lsuch as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is arisk
of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
! There is
arisk of damage to the vehicl eif:
R the vehicl ebecome sstuck, e.g. on ahigh
kerb or an unpaved road
R you drive too quickly over an obstacle, e.g.
ak erb, slowing thresholds or apothol ein
the road
R ah eavy object strikes the underbody or
parts of the chassis
In situations like this, the body ,underbody,
chassi sparts, wheels or tyres coul dbedam-
agedw ithout the damage being visible. Com-
ponents damaged in this way can unexpect-
edlyf ail or, in the case of an accident, no lon-
ger withstand the strain they are designed to withstand.
If the underbody panelling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody panelling. If these materials
come into contact with hot parts of the
exhaust system, they can catch fire.
In such situations, have the vehicl echecked
and repaired immediatel yataqualified spe-
cialist workshop. If, on continuing yourj our-
ney, you notice that driving safety is impaired, stop the vehicle immediately
,paying atten-
tion to road and traffic conditions. In such
cases, consult aqualified specialist work-
shop.
! If there are steep gradients while driving off-
road, asufficient filling level in the AdBlue ®
tank must be ensured. Make sure for this rea- son that there is aminimum fill level of ten
litres before driving off-road.
When driving off-road, substances such as sand,
mud and water or water mixed with oil may get
into the brakes. This may lead to areduction in
braking performance or total brake failure as a
result of increased wear. The braking charac-
teristics will vary depending on the substances
that get into the brakes. Cleant he brakes after
driving off-road. If you notice grinding noises or ar eduction in braking performance, have the
brake system checked at aqualified specialist
workshop immediately.A dapt your driving style
to the altered braking characteristics.
Driving off-road increases the possibility of dam- age to the vehicle, which may cause assemblies
or systems to fail. Adapt your driving style to the
conditions of the terrain. Drive carefully.H ave
vehicle damage rectified immediately at aquali-
fied specialist workshop.
Do not shift into transmission position Nwhen
driving off-road. You could lose control of the
vehicle if you attempt to brake the vehicle using
the service brake. If the gradient is too steep for your vehicle, back up in reverse gear.
