WARNING Risk of skidding and of an
accident due toshifting down on slippery
ro ad sur faces
If yo u shift down on slippery road sur faces to
inc rease the engine braking ef fect, the drive
wheels may lose traction. #
Do not shift down on slippery road sur‐
fa ces toinc rease the engine braking
ef fect. Ve
hicles with automatic transmissions may roll in
neut ral position 005Cfor only a short time. Allowing
th e wheels torollfo r longer, e.g. when towing,
causes transmission damage.
If th eve hicle thre atens toskid, or cannot be stop‐
ped when tr aveling at a low speed, you can stabi‐
lize theve hicle using thefo llowing measures:
R Shift the automatic transmission toneutral
position 005C.
R Tryto maintain control of theve hicle using
cor rective steering.
Drive particularly carefully on slippery roads.
Av oid sudden acceleration, steering and braking
maneuvers.
Ha ve your vehicle winterized at a qualified spe‐
cialist workshop in good time at the onset of win‐
te r.
Obser vethe no tes on snow chains
(/ page 309).
Re gular lych eck theve hicle and remo vesnow or
ice when tr aveling in wintry conditions.
An accumulation of snow and ice, particular ly
when frozen, in the area around the air intake,
moving parts, the axles and the wheel housing,
may cause thefo llowing problems:
R Obstruction of the air intake
R Damage tovehicle parts
R Malfunctions due torestriction of mobility
intended bythe design (e.g. reduced steering
mo vement)
If th ere is any damage, inform a qualified special‐

Checklist af ter driving off-road
Driving over rough terrain places greater
demands on your vehicle than normal road opera‐
