R
only use a spare wheel that differs from the
wheel to be replaced for a short time.
R
have a spare wheel that differs from the
wheel that has been changed replaced at
the nearest qualified specialist workshop.
You must observe the correct wheel and
tyre dimensions as well as the wheel type.

WARNING
M+S tyres with a tyre tread depth of less than
4 mm are not suitable for use in winter as they
do not provide sufficient traction. There is a
risk of accident.
M+S tyres with a tread depth of less than
4 mm must be replaced.
Use winter tyres or all-season tyres at temper-
atures below +7 †. Both types of tyre are iden-
tified by the M+S marking.
Only winter tyres bearing the
i
snowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions.
Only these tyres will allow driving safety sys-
tems such as ABS and ESP
®
to function opti-
mally in winter. These tyres have been devel-
oped specifically for driving in snow.
Use M+S tyres of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximum permissible
speed specified for the M+S tyres you have fit-
ted.
If you fit M+S tyres that have a lower maximum
permissible speed than the maximum design
speed of the vehicle, affix a corresponding warn-
ing label in the driver's field of vision. You can
obtain this at a qualified specialist workshop.
If you fit M+S tyres and change the wheel size in
the process, check that the tyres are assigned to
the wheel size group (
Y
page 355). If the assign-
ment changes without recoding the control
units in the vehicle, the speedometer will not
display the speed accurately. Driving safety sys-
tems and driving systems may then be opera-
tionally impaired or may detect a fault and
switch themselves off.
Vehicles with SPEEDTRONIC: under these cir-
cumstances, you should also use permanent
SPEEDTRONIC to restrict the maximum design
speed of the vehicle so that it does not exceed
the maximum permissible speed of the
M+S tyres (
Y
page 191).
Once you have fitted the winter tyres:
X
Check the tyre pressure (
Y
page 359).
X
Restart the tyre pressure monitor
(
Y
page 363).

WARNING
If you have fitted snow chains to the front
wheels, they may scrape against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tyres.
There is a risk of an accident.
To avoid hazardous situations:
R
never fit snow chains on the front wheels
R
fit snow chains to the rear wheels in pairs.
Vehicles with front-wheel drive (engine
power output below 100 kW):
G
WARNING
If snow chains are fitted to the rear wheels,
they may scrape against the vehicle body or
chassis components. This could cause dam-
age to the vehicle or the tyres. There is a risk
of an accident.
To avoid hazardous situations:
R
never fit snow chains on the rear wheels
R
always fit snow chains in pairs to the front
wheels.
For all vehicles:
G
WARNING
If you drive too fast with snow chains fitted,
they may snap. As a result, you could injure
others and damage the vehicle. There is a risk
of an accident.
Observe the maximum permissible speed for
operation with snow chains.
When driving with snow chains fitted, do not
exceed the maximum permissible speed of
