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.
For the best possible handling, use all-season or "winter" tyres on all four
wheels with a minimum tread depth of 4 mm.
If using "winter" tyres, fit the summer tyres on again in good time as they pro-
vide 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 tem-
peratures above 7 °C.
Speed symbol
All-season or "winter" tyres (marked with M+S and a peak/snowflake symbol
) of a lower speed category than stated in the technical vehicle documenta-
tion can be used, provided the permissible maximum speed of these tyres is
not exceeded even if the possible maximum speed of the vehicle is higher.
The speed limit for all-season or "winter" tyres can be set in the infotainment
system in menu
/ → → Tyres.
If the vehicle has all-season or "winter" tires of a lower speed category then

the vehicle in a constantly visible place in the driver's field of vision. The warn-
ing label (sticker) can be replaced by setting the maximum value of the speed
