In vehicles with tyre pressure monitoring, save the tyre pressure values in the
system » page 106 .WARNING■
Never drive with more than one temporary spare wheel mounted!■Avoid full throttle acceleration, sharp braking and fast cornering when
driving with the temporary spare wheel.■
Do not use snow chains on the temporary spare wheel.

Operating in winter conditions
All-year (or “winter”) tyres
All-year or “winter”tyres (indicated by an M+S or a mountain peak/snowflake
symbol ) to improve the performance of the vehicle in winter conditions.
To get the best possible driving characteristics, all-year or “winter”tyres, with a
minimum tread depth of 4 mm on all four wheels, should be fitted.
If “winter” tyres are fitted, summer tyres should be fitted again in good time as
they provide better handling properties, a shorter braking distance, less tyre
noise and reduced tyre wear on roads which are free of snow and ice as well
as at temperatures above 7 °C.
Speed symbol
All-year or “winter”tyres (marked with M+S and a peak/snowflake symbol
) of
a lower speed category than listed in the vehicle’s technical documentation
can be used provided that the maximum permissible speed for these tyres is
not exceeded even if the maximum possible speed of the vehicle is higher.
For vehicles with Infotainment, use the button to adjust the speed limit for
all-year or “winter” tyres » Owner´s Manual - Infotainment . For other vehicles,
there is the possibility to set the speed limit for winter tyres at a specialist ga-
rage.
the vehicle has all-season or “winter” tyres with a speed category that is lower
than the specified top speed of the vehicle (does not apply to factory-supplied tyres), a warning label with the maximum value of the speed category supplied
for the mounted tyres in the interior of the vehicle and in a place which is con-
stantly visible in the driver’s field of vision. The warning label (sticker) can be
replaced by setting the maximum value of the speed category supplied for the mounted tyres in Infotainment 1)
. This specification defines the maximum vehi-
cle speed with mounted all-season or “winter”tires that must not be exceeded.
