MOBILITY
Maximum speed
Safety information
Warning
If the maximum permissible speed of your
mounted tires is exceeded, the tires may be
damaged. There is a risk of accident. Do not
exceed the maximum permissible speed of
the tires.
Maximum speed of winter tires
If the maximum speed of the vehicle is higher
than the permissible speed of the winter tires,
the maximum permissible speed must be indi-
cated with a sign placed in the field of vision.
The info label is available from an authorized
service center or another qualified service cen-
ter or repair shop.
Winter tires
General information
Winter tires are recommended for operating on
winter roads.
Winter tires can be identified by the icon with
mountain and snowflake, as well as the M+S
marking on the tire sidewall.
All-season tires with the M+S designation, but
without icon with mountain and snowflake,
have better winter characteristics than summer
tires but generally do not achieve the perform-
ance of winter tires.
