3.2.3

Wash snow chain in hot water immediately after use and dry it.
Visually inspect the snow chain for signs of damage and adequate wire strength (chain links).
Snow chains must NOT be oiled! Spray snow chains with commercially available anti-rust agent
if necessary.
After drying, stow dry snow chains back in the vehicle if necessary.
Snow chains are made of high-quality steel, but are not rust-resistant. A small amount of rust will
not impair the quality of the snow chains.

– Snow chains (2 ea.) installed on rear axle
Includes:
Reading instructions.
Checking snow chains for damage before installing and
installing snow chains.
Checking that snow chains are installed correctly and
