MOBILITY
WARNING
Incorrect wheel/tyre combinations impair the
vehicle's handling characteristics and interfere
with the proper functioning of various systems,
such as the Anti-lock Brake System or Dy‐
namic Stability Control. There is a danger of ac‐
cidents. To maintain good vehicle handling, al‐
ways fit tyres of the same make and tread
pattern to all wheels. The manufacturer of the
vehicle recommends using wheels and tyres
that have been categorised as suitable for the
respective vehicle type. After a tyre has been
damaged, refit the same wheel/tyre combina‐
tion as the original.
Recommended makes of tyre
Certain makes of tyre are recommended by the
manufacturer of the vehicle for each tyre size.
The tyre brands can be identified by a star on the
side wall of the tyre.
New tyres
Due to the manufacturing process, new tyres do
not provide maximum grip immediately.
Drive moderately for the first 300 km, 200 miles.

Wheels and tyres
Retreaded tyres
Retreaded tyres may have different tyre car‐
casses. Their durability may be reduced with
increasing age. There is a danger of accidents.
Do not use retreaded tyres.
The manufacturer of your vehicle advises against
the use of retreaded tyres.
Winter tyres
General
Winter tyres are recommended if driving in winter
conditions.
Although so-called all-season tyres with an M+S
label have better winter characteristics than sum‐
mer tyres, they do not normally match the per‐
formance of winter tyres.
Maximum speed of winter tyres
If the vehicle is capable of maximum speeds
higher than the speed permitted for the winter
tyres, display an indicating label stating the maxi‐
mum permitted speed in the driver's field of view.
The indicating label is available from a Service
Partner of the manufacturer or another qualified
Service Partner or a specialist workshop.
If winter tyres are fitted, observe and do not ex‐
ceed the respectively permitted maximum
speed.
Replacing run-flat tyres
For your own safety, only use run-flat tyres.
There is no spare wheel available in the event of
a breakdown. Additional information is available
from a Service Partner of the manufacturer or an‐
other qualified Service Partner or a specialist
workshop.
