Slippery road surfaces

WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
Move the transmission to position N.

Important safety notes

WARNING
If you drive up a steep incline at an angle or
turn on a steep incline, the vehicle could slip
sideways, tip and overturn. There is a risk of
an accident.
When driving up an incline, drive into the line
of fall (upwards or downwards in a straight
line) and do not turn.
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 a
reduction in braking performance or total
brake failure as a result of increased wear.
The braking characteristics will vary depend-
ing on the substances that get into the
brakes. Clean the brakes after driving off-
road. If you notice grinding noises or a reduc-
tion in braking performance, have the brake
system checked at a qualified specialist work-
page 353).
Y
shop immediately. Adapt your driving style to
the altered braking characteristics.
Driving off-road increases the possibility of
damage to the vehicle, which may cause
assemblies or systems to fail. Adapt your
driving style to the conditions of the terrain.
Drive carefully. Have vehicle damage rectified
immediately at a qualified specialist work-
shop.
Do not shift into transmission position N
when 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.
