Observe the following when selecting, installing
and replacing tires:
R
Only use tires and wheels of the same type
(summer tires, winter tires, MOExtended
tires) and the same make.
R
Only install wheels of the same size on one
axle (left and r ight).
It is only permissible to install a different
wheel size in the event of a flat tire in order
to drive to the specialist workshop.
R
Only install tires of the correct size onto the
wheels.
R
Vehicles with a tire pressure monitoring
system: All installed wheels must be equip‐
ped with functioning sensors for the tire
pressure monitoring system.
R
At temperatures below 45 °F (7 °C), use win‐
ter tires or all-season tires mar ked M+S for
all wheels.
Winter tires bearing the i snowflake sym‐
bol in addition to the M+S marking provide
the best possible grip in wintry road condi‐
tions.
R
For M+S tires, only use tires with the same
tread.
R
Observe the maximum permissible speed for
the M+S tires installed.
If this is below the vehicle's maximum speed,
this must be indicated by an appropriate
label in the driver's field of vision.
R
Break in new tires at moderate speeds for
the first 60 miles (100 km).
R
Replace the tires after six years at the latest,
regardless of wear.
R
When replacing with tires that do not fea‐
ture run-flat characteristics: vehicles with
MOExtended tires are not equipped with a
TIREFIT kit at the factory. Equip the vehicle
with a TIREFIT kit after replacing with tires
that do not feature run-flat characteristics,
e.g. winter tires.
For more information on wheels and tires, con‐
tact a qualified specialist workshop.

WARNING Risk of accident caused by
non-approved tire types
If you use tire types that have not been adap‐
ted to changes made to the factory speed
limit, this can have the following consequen‐
ces:
R
The tires do not exhibit the required qual‐
ity characteristics and are not suitable for
high speeds or the relevant driving
dynamics.
R
The tires wear unevenly and could, there‐
fore, affect the roadworthiness of the
vehicle.
R
ABS, ESP
®
and cruise control operation
are restricted.
This can jeopardize road safety.
