Notes on snow chains

& WARNING Risk of accident due to incor‐

the vehicle body or chassis components.
This could cause damage to the vehicle or
the tires.
Never mount snow chains on the front
#
wheels.
Only mount snow chains on the rear
#
wheels in pairs.

vehicle body or chassis due to mounted
snow chains
If you mount snow chains to the front wheels
of 4MATIC vehicles, you may damage compo‐
nents of the vehicle body or chassis.
Only mount snow chains to the rear
#
wheels of 4MATIC vehicles.
Observe the following notes when using snow
chains:
Snow chains are only permissible for certain

information about this from an authorized
Mercedes-Benz Center.
For safety reasons, only use snow chains that
