On vehicles fitted with a tyre pressure
monitor*, electronic components are loca-
ted in the wheel.
Tyre fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the wheels interchanged/
changed at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
Winter driving
Points to remember
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at a Mercedes-Benz
Service Centre, at the onset of winter.
Winter tyres
Use winter tyres at temperatures below +7 °
C and on snow or ice-covered roads. Only
then can the effect of the ABS, ESP
®
and
4MATIC* driving systems be ensured in win-
ter too.
Use winter tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics.
G
Risk of accident
Winter tyres with a tread depth of less than
4 mm must be replaced immediately. They
are no longer suitable for winter use, can
no longer provide sufficient grip. This could
cause you to lose control of your vehicle
and cause an accident.
Always observe the maximum permitted
speed specified for the winter tyres you have
fitted. If you fit winter tyres which have a
lower maximum permitted speed than that of
the vehicle, affix an appropriate warning sign
in the driver's field of vision. This can be
obtained at a qualified specialist workshop,
e.g. from a Mercedes-Benz Service Centre.
In such circumstances, you should also
restrict the maximum speed of the vehicle
using permanent Speedtronic
32
to the maxi-
mum permissible speed for winter tyres
(

page 154).
Once you have fitted the winter tyres:
X
Check the tyre pressures (

page 229).
X
Restart the tyre pressure moni-
tor* (

page 232).
G
Risk of accident
If you fit the spare wheel* when driving with
winter tyres, bear in mind that driving sta-
bility will be impaired owing to unstable
cornering characteristics caused by the dif-
ferent tyres. You should therefore adapt
your driving style and drive carefully.
Have the spare wheel* replaced at the
nearest qualified specialist workshop
which has the necessary specialist knowl-
edge and tools to carry out the work
required. Mercedes-Benz recommends
