WARNING
If you have fitted snow chains to the front

! 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.
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:
snow chains cannot be fitted to all wheel-

tyre combinations. Permissible wheel-tyre
combinations ( page 357).
Y
only use snow chains when the road sur-
R
face is completely snow-covered. Remove
the snow chains as soon as possible when
you come to a road that is not snow-cov-
ered.
local regulations may restrict the use of
R
snow chains. Observe the appropriate reg-
ulations if you wish to fit snow chains.
