R
Vehicles with a tyre pressure monitor: all
fitted wheels must be equipped with func-
tioning sensors for the tyre pressure monitor.
R
At temperatures below 7 °C, use winter tyres
or all-weather tyres with the M+S marking on
each wheel.
Winter tyres bearing the
i
snowflake sym-
bol in addition to the M+S marking provide the
best possible traction in wintry road condi-
tions.
R
Only use tyres of the same tread on M+S
tyres.
R
Observe the maximum permissible speed
specified for the M+S tyres you have fitted.
If this is lower of that than the vehicle an
appropriate warning label must be affixed in
the driver's field of vision.
R
Run in new tyres at moderate speeds for the
first 100 km.
R
Replace the tyres after six years at the latest,
regardless of wear.
For further information on wheels and tyres,
please contact a qualified specialist workshop.

WARNING
Due to the special tyre tread in combination
with the optimised rubber compound, there is
an increased risk of aquaplaning and skidding
on a damp or wet road surface. Tyre grip is
also noticeably reduced at low outside tem-
peratures and low tyre operating tempera-
tures. There is a risk of an accident.
Turn on ESP
®
and adapt your driving style
accordingly. When the outside temperature
falls below 10 †, use M+S tyres.
Notes on interchanging wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions.
The wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
Interchanging front and rear wheels of differing
dimensions can render the general operating
permit invalid.
Wear patterns for the front and the rear tyres
vary:
R
Front tyres typically wear more on the tyre
shoulders
R
Rear tyres typically wear more in the centre of
the tyre
On vehicles that have the same size wheels,
interchange the wheels every 5000 to
10,000 km depending on the degree of wear.
Ensure the direction of rotation is maintained.
Always observe the instructions and safety
notes on changing a wheel .
Notes on storing wheels
Observe the following notes on storing wheels:
R
wheels that have been removed should be
stored in cool, dry and preferably dark sur-
roundings.
R
protect the tyres against oil, grease and fuel.
Overview of tyre-change tool kit
Apart from some country-specific variants, vehi-
cles without a spare wheel are not equipped
with tyre-changing tools. For more information
on which tools are required and approved to
perform a wheel change on your vehicle, consult
a qualified specialist workshop.
Necessary tyre-changing tools may include, for
example:
R
Jack
R
Wheel chock
R
Wheel wrench

The jack has a weight of approximately
3.2 kg.
