according to location or type of road. Always check the
local regulations before installing chains.
NOTICE
If the wrong combination of tire and chain is used, the
chains could damage the vehicle body.

Install the chains on the front tires as tightly as possible.
Do not use tire chains on the rear tires. Retighten chains
after driving 0.5 — 1.0 km (1/4 — 1/2 mile).
When installing chains on your tires, carefully follow the
instructions of the chain manufacturer.
