WARNING■Change when they are worn down to the wear indicators at the latest -
risk of accident.■
Improper wheel alignment affects the driving behaviour - there is an acci-
dent.
■
Unusual vibrations or “pulling” of the vehicle to one side could be a sign
of tyre damage. Reduce speed and stop! If no tyre damage is evident, seek
the assistance of a specialist garage.
Spare wheel
Use the emergency spare wheel only to reach the nearest specialist garage, as
it is not intended for permanent use .
A warning label is displayed on the rim of the temporary spare wheel.
Please note the following if you intend to use the temporary spare wheel. ▶ Do not cover the signs.
▶ Be particularly observant when driving.
▶ Inflate the temporary spare wheel to the maximum inflation pressure for the
vehicle » page 277 (the prescribed tyre pressure of the spare wheel R 18 is
4.2 bar).
In vehicles with tyre pressure monitoring, save the tyre pressure values in the
system » page 249 .
WARNING■
Never drive with more than one spare wheel mounted!■When driving with the temporary spare wheel at full throttle acceleration,
avoid sharp braking and fast cornering.■
Do not use snow chains on the temporary spare wheel.
■
Observe instructions on the warning sign of the emergency wheel.

Operating in winter conditions
All-year (or “winter”) tyres
All-season or “winter”tyres (indicated by an M+S or a mountain peak/snow-
flake symbol ) to improve the performance of the vehicle in winter condi-
tions.
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.
