Winter operation
320
Only winter tyres bearing the i snowflake
symbol in addition to the M+S marking pro-
vide the best possible grip in wintry road con-
ditions. Only these tyres will allow driving
safety systems such as ABS and ESP
function optimally in winter, as these tyres
have been designed specifically for driving on
snow.
Use M+S tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics.
G
WARNING
M+S tyres with a tread depth of less than
4 mm must be replaced. They are no longer
suitable for winter use and can no longer pro-
vide sufficient grip. This could cause you to
lose control of your vehicle and cause an acci-
dent.
Always observe the maximum permissible
speed specified for the M+S tyres you have
fitted.
If you fit M+S tyres which have a lower max-
imum permissible speed than that of the vehi-
cle, affix an appropriate warning sign in the
driver's field of vision. This can be obtained
at a qualified specialist workshop, e.g. at a
Mercedes-Benz Service Centre.
Under these circumstances, you should also
restrict the maximum speed of the vehicle
using permanent SPEEDTRONIC so that it
does not exceed the maximum permissible
speed for the M+S tyres (
When you have fitted the M+S tyres:
Check the tyre pressures (

WARNING
If you fit the spare wheel when driving with M
+S tyres, bear in mind that driving stability will
be impaired due to unstable cornering char-
acteristics caused by the different 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 knowledge and tools to
carry out the work required. Mercedes-Benz
recommends that you use a Mercedes-Benz
Service Centre for this purpose. In particular,
work relevant to safety or on safety-related
systems must be carried out at a qualified
specialist workshop.
Snow chains
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specially approved for your vehicle
by Mercedes-Benz, or that are of a corre-
sponding standard of quality.
If you intend to fit snow chains, please bear
the following points in mind:
it is not permissible to attach snow chains
R
to all wheel-tyre combinations; see the
information under "Wheel/tyre combina-
tions" in the "Wheels and tyres" section.
snow chains must not be fitted to emer-
R
gency spare wheels, e.g. a "Minispare"
emergency spare wheel.
fit snow chains only in pairs and only to the
R
rear wheels. Observe the manufacturer's
installation instructions.
! Vehicles with steel wheels: if you wish
to fit snow chains to steel wheels, make
sure that you remove the respective
wheels' hubcaps first. The hubcaps may
otherwise be damaged.
Do not exceed the maximum permissible
speed of 50 km/h.
i
You may wish to deactivate ESP
( page 64) when pulling away with snow
Y
chains fitted. This way you can allow the
wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action).
