Driving in sand and mudYou should therefore always drive at a constant speed through sand or mud whenever possible and at the same time do not shift gears or change the driving stage. –Switch on the Off-road mode
⇒page 170.
– Select a suitable gear or driving stage and maintain the gear or driving stage. – Keep your vehicle in constant motion and
do not stop until you have reached firm
ground.
Never drive too fast, otherwise the wheels may spin and the vehicle can get stuck. If you feel that the tyres do no longer grip, then turn the steering wheel quickly back and forth. This leads to an improved adhesion of the front tyres of the vehicle for a short period of time. Driving through sand Do not reduce
the tyre inflation pressure. If you nevertheless reduce the inflation
pressure, do not forget to re-establish the correct tyre inflation pressure level before you continue driving. Driving with a reduced tyre inflation pressure increases the risk that you lose control over your vehi
cle and that the vehicle rolls over.
Driving through mud Do not change speed or direction when you
drive through the mud.
The tyres can lose
their grip in the mud. If th
e vehicle slides, you must stee
r in the appropriate direction
in order to regain control over the vehicle.
WARNING
•
Driving through mud can be dangerous. The vehicle can slide uncontrol-
lably which causes an increased risk of injury. Adopt a particularly cautious style of driving. Pay attention to the information and warning notes.•
An incorrect tyre inflation pressure may cause a major or fatal accident! An
incorrect tyre inflation pressure may result in bursting of a tyre, which causes the vehicle to get out of control.•
Observe the important guidelines
⇒page 180.
Stuck vehicleIf you can no longer drive on ...– Carefully dig out all the wheels and make sure that no other parts of the vehicle are
stuck in the sand.
– Engage the reverse gear. – Gently depress the accelerator and try
to drive backwards in your own track.
– Place scrub, footmats or a sackcloth directly
in front of the tyres in order to improve
the road adherence and thus achieve an improved traction to drive out.
Rocking out vehicle– Switch off the TCS
⇒page 165.
– Set the steering wheel straight. – Drive so far back until the wheels just begin to spin.– Quickly shift into first gear and drive
forwards until the wheels begin to spin.
– Drive back and forth repeat
edly until the momentum is
sufficient to free the
vehicle.
– Switch on the TCS.A few tips– Ensure that the Off-road mode is switched on
⇒page 170.
– Avoid prolonged spinning of the wheels,
otherwise the vehicl
e would still sink
deeper into the ground.
– Remove mud, dirt and stones from the tread of the tyre. You need training and
experience if you wish to rock
out a vehicle. If you make a
mistake, the vehicle can still sink in further
and you can only free it with the help of
others.

Technical Data
Winter tyres must be mounted on all four
wheels to obtain the best handling charac-
teristics. You must only fit those types of winter tyre
which are approved for your vehicle. The
permissible
sizes of winter tyres
are stated in your vehicle documents. Approvals may
differ because of na
tional legislation.
Please remember that the tyres should be inflated to 20 kPa (0.2 bar) more than is the case for summer tyres
⇒page 215.
Winter tyres no longer offer the same winter performance once the
tyre tread
has
worn down to a depth of about 4 mm. Ageing
also causes winter tyres to lose most of their winter performance properties -
even in cases where the remaining tread depth is still clearly more than 4 mm. Speed restrictions
apply to winter tyres as well as to summer tyres
⇒page 217,
⇒
.
You can fit winter tyres of a lower speed catego
ry to your vehicle provided that you also
do not drive faster than the permissible maximum speed for such tyres, even if the possible maximum speed of your vehicle is
higher. The correspond
ing tyre category
can damage the tyres when exceeding the permissible maximum speed. Please pay attention to the notes if you decide to fit winter tyres
⇒page 215.
You can also fit so-called “all-year tyres” instead of winter tyres. Please contact your specialist garage if there are any points which are not clear who will be able to provide you with information regarding the maximum speed for your tyres.
WARNING
You must on no account drive your car at more than the permissible maximum speed for your winter tyres - risk of an
accident resulting from tyre damage and
loss of control over your car.
For the sake of the environment
Fit your summer tyres on again in good time since summer tyres offer you better grip and handling on roads which are free of snow and ice as well as ar temperatures below 7 °C - the braking distance is shorter, there is
less tyre noise, tyre wear is reduced and
fuel consumption is reduced.
Note
Please observe the various differing legal requirements regarding tyres.Unidirectional tyres*The direction of rotation of the tyres is marked by
arrows on the wall of the tyre
. This
indicates the direction of rotation of the tyre,
and it is essential that the tyres are fitted
on to run in this direction. Only then are
the tyres able to provide the optimal proper-
ties in terms of grip, low nois
e, wear-and-tear and aquaplaning.
Should it be necessary to fit on a spare wheel
in exceptional cases with a tyre not dedi-
cated to the running direction or in oppo
site running direction, please adopt a
cautious style of driving as the tyre is no
longer able to provide optimal grip and
handling in such a situation. This particular
ly important on wet roads. Please refer to
the notes
⇒page 224, “Spare wheel*”.
You should have the defective tyre replaced as soon as possible and restore the correct direction of rotation on all tyres.Snow chainsWhen driving on wintry roads, snow chains
improve not only traction, but also the
braking performance. The use of snow chains on ve
hicles with front-wheel drive and on vehicles with four-
wheel drive differs. Valid for vehicles with front-wheel drive Snow chains can only be mounted on the front wheels. For technical reasons, it is only permissi
ble to fit snow chains
with the following
wheel/tyre combinations:
