MOBILITY
New tyres
Due to the manufacturing process, new tyres do
not achieve their full road grip immediately.
Drive moderately for the first 300 km, 200 miles.
Retreaded tyres
WARNING
Retreaded tyres may have different tyre car‐
casses. Their durability may be reduced with
increasing age. There is a risk of accident. Do
not use retreaded tyres.
The vehicle manufacturer advises against the
use of retreaded tyres.
Winter tyres
General
Winter tyres are recommended if driving in winter
conditions.
Although tyres known as all-season tyres with an
M+S label have better winter characteristics than
summer tyres, they do not normally match the
performance 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, an information label stating the maximum
permitted speed for the tyres fitted must be dis‐
played in the driver's field of view. The label is
available from a Service Partner of the manufac‐
turer 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

Swapping over front and rear
wheels
Swapping over of wheels between axles on ve‐
hicles with different tyre sizes or rim dimen‐
sions on the front and rear axles may cause tyre
damage and damage to the vehicle. There is a
risk of accident. Do not swap over wheels be‐
tween axles on vehicles with different tyre sizes
or rim dimensions on the front and rear axles.
Different tyre tread wear patterns occur on the
wheels of the front and rear axles, depending on
the individual operating conditions. To achieve
even wear, the tyres can be swapped over in
pairs between the axles. Additional information is
available from a Service Partner of the manufac‐
turer or another qualified Service Partner or a
specialist workshop. After swapping over, check
the tyre inflation pressure and adjust if neces‐
sary.

sure indicated on the tyre's side wall.
