Snow Chains - Mercedes-Benz A-Class Series Owner's Manual

Only these tyres will allow the ABS and
®
ESP driving systems to 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
Risk of accident
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. from a
Mercedes-Benz Service Centre.
Under these circumstances, you should also
restrict the maximum speed of the vehicle
using permanent SPEEDTRONIC
does not exceed the maximum permissible
speed for the M+S tyres (
When you have fitted the M+S tyres:
Check the tyre pressures (

G Risk of accident
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

Snow chains

For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains which
have been specially approved for your vehicle
by Mercedes-Benz, or are of a corresponding
standard of quality.
If you intend to fit snow chains, please bear
the following points in mind:
you may not attach snow chains to all
R
wheel-tyre combinations; see the "Tyres
and wheels" section in the "Technical data"
chapter.
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
front wheels. Observe the manufacturer's
installation instructions.
! Vehicles with 17" tyres
You may only fit snow chains as a pulling-
away aid. Only use fine-link snow chains.
When snow chains are fitted, you may only
drive straight ahead. The snow chains could
otherwise come into contact with the body-
work when you turn the front wheels.
! 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 hub-
caps may otherwise be damaged.
If snow chains are fitted, you cannot use
Active Parking Assist (
Do not exceed the maximum permissible
speed of 50 km/h.
