of skidding or hydroplaning on wet roads is
increased.
In addition, the tire grip is greatly reduced at
a low outside temperature and tire running
temperature.
#
Switch on the ESP
®
and adapt your
driving style accordingly.
#
Use M+S tire at outside temperatures
of less than 10 °C (50 °F).
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 right).
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 tire marked 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.
