Only put snow chains on the front wheels(also applies to all-wheel drive vehicles).
If accessory, aftermarket or "custom"tires and wheels with different dimen-sions than the original tires and wheelsare used, snow chains in some casesmay NOT be used. Sufficient distancebetween the chains and brakes, suspen-sion and body components must bemaintained.
Check local regulations regarding the useof snow chains before installing.

The handling of the vehicle can beadversely affected when driving withchains. Avoid fast or sharp turns as wellas locked wheel braking.
Some types of strap-on chains affectbrake components and therefore mustNOT be used.
