Using snow chains
Snow chains may only be used on the front
wheels (also applies to all-wheel drive cars).
Never drive faster than 50 km/h with snow
chains. Avoid driving on bare ground as this
wears out both the snow chains and tyres.
WARNING
Use Volvo genuine snow chains or equiva-
lent chains designed for the car model,
and tyre and rim dimensions. In the event
of uncertainty Volvo recommends that you
consult an authorised Volvo workshop.
The wrong snow chains may cause serious
damage to your car and lead to an acci-
dent.
