Maximum speed of winter tires
If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then display a corresponding sign in the field of
vision. You can obtain this sign from the tire
specialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for
the winter tires; otherwise, tire damage and ac‐
cidents can occur. ◀
Run-flat tires When mounting new tires or changing fromsummer to winter tires or vice versa, use run-
flat tires for your own safety. Also, a compact
wheel is not available in case of a flat tire. Your
service center will be glad to advise you.
Rotating wheels between axles
Different wear patterns occur on the front and
rear axles, depending on the individual condi‐
tions of use.
To ensure even wear on the tires, the wheels
can be rotated between the axles. Your service
center will be glad to advise you.
After changing the tires, check the tire inflation
pressure and correct it if necessary.
Storage Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.Run-flat tires
Label
The symbol identifying run-flat tires is a circle
with the letters RSC on the sidewall.
Run-flat tires are tires that support themselves
for a limited period of time, and they may also
come with special rims. The sidewall reinforce‐
ment ensures that the tire can continue to be
used to a limited extent if it has lost pressure
and even if it has become completely depres‐
surized.
For continued driving in the event of a flat tire,
refer to page 75.

sprays or other care products containing sili‐
cone; otherwise, noise and damage may result.
Chrome surfaces
Carefully clean components such as the radia‐

as for Park Distance Control, must be kept clean
and free of ice to ensure that they remain fully
functional.
Decorative trim
