Installing the chains
1. If your vehicle is equipped with
wheel covers remove them,
otherwise the chain bands will
scratch them.
2. Secure the chains on the front tyres
as tightly as possible. Always follow
the chain manufacturer's
instructions.
3. Retighten the chains after driving
1/2―1 km (1/4―1/2 mile).
