Snow chains

G WARNING
If snow chains are mounted on the rear
wheels, the snow chains could cause abrasion
to the vehicle body or to chassis components.
This could cause damage to the vehicle or the
tires. There is a risk of an accident.
To avoid hazardous situations:
never mount snow chains on the rear
R
wheels
only mount snow chains in pairs on the
R
front wheels.
! On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and
tire combinations" section under "Tires and
wheels".
! Vehicles with steel wheels: if you
mount snow chains on steel wheels, you
may damage the hub caps. Remove the hub
caps from the relevant wheels before
mounting the snow chains.

Only use snow chains when driving on
R
roads completely covered by snow.
Remove the snow chains as soon as
possible when you come to a road that is
not snow-covered.
Local regulations may restrict the use of
R

regulations if you wish to mount snow
chains.
Do not exceed the maximum permissible
