Winter tyres
In winter conditions winter tyres will consid-
erably improve the vehicle's handling. The
design of summer tyres (width, rubber com-
pound, tread pattern) gives less grip on ice
and snow.
Winter tyres must be inflated to a pressure of
0.2 bar (2.9 psi/20 kPa) higher than the pres-
sures specified for summer tyres (see the
sticker on the back of the left front door
frame).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes
can be found in the vehicle's registration
documentation. Use only radial winter tyres.
All tyre sizes listed in the vehicle documenta-
tion also apply to winter tyres.
Winter tyres lose their effectiveness when the
tread is worn down to a depth of 4 mm.

The speed rating code
tyres and wheels
determines the following
speed limits for winter tyres:
Q
max. 160 km/h (99 mph)
S
max. 180 km/h (112 mph)
T
max. 190 km/h (118 mph)
H
max. 210 km/h (130 mph)
272
In some countries, vehicles which can exceed
the speed rating of the fitted tyre must have
an appropriate sticker in the driver's field of
view. These stickers are available from your
technical service. The legal requirements of
each country must be followed.
Do not have winter tyres fitted for unnecessa-
rily long periods. Vehicles with summer tyres
handle better when the roads are free of
snow and ice.
If you have a flat tyre, please refer to the
notes on the spare wheel
tyres and
WARNING
The maximum speed for the winter tyres must
not be exceeded. Otherwise, this could lead
to damage and risk of accident.
For the sake of the environment
Fit your summer tyres again as soon as possi-
ble. They are quieter, do not wear so quickly
and reduce fuel consumption.
