MOBILITY
Warning
Mounted steel wheels can cause technical
problems, for instance unexpected loosening of
the lug bolts and damage to the brake discs.
There is a risk of accident. Do not mount steel
wheels.
Warning
Incorrect wheel/tire combinations will impair the
vehicle's handling characteristics and a variety
of system functions, such as the Antilock Brak‐
ing System (ABS) or Dynamic Stability Control.
There is a risk of accident. To maintain good
handling and vehicle response, use only tires
with a single tread configuration from a single
manufacturer. The manufacturer of the vehicle
recommends that you use wheels and tires that
have been recommended by the vehicle manu‐
facturer for your vehicle type. Following tire
damage, have the original wheel/tire combina‐
tion remounted on the vehicle as soon as pos‐
sible.
Recommended tire brands
For each tire size, the manufacturer of the vehi‐
cle recommends certain tire brands. The tire
brands can be identified by a star on the tire
sidewall.
New tires
Tire traction is not optimal due to production-re‐
lated circumstances when tires are brand-new.

Winter tires
General information
Winter tires are recommended for operating on
winter roads.
Although so-called all-season tires with M+S
identification provide better winter traction than
summer tires, they usually do not provide the
same level of performance as winter tires.
Maximum speed of winter tires
If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then attach a label showing the permissible maxi‐
mum speed in the field of vision. The label is
available from a dealer's service center or an‐
other qualified service center or repair shop.
With winter tires mounted, observe and do not
exceed the permissible maximum speed.
Changing runflat tires
When changing from run-flat tires to standard
tires, it must be ensured that the vehicle contains
a compact spare tire ("donut") or tire mobility kit.
Further information is available from a dealer's
service center or another qualified service center
or repair shop.
