Using Snow Chains

WARNING: Do not exceed 30 mph (50 km/h). Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death.
WARNING

WARNING: Do not use snow chains on snow-free roads.
WARNING

WARNING: Only fit snow chains to specified tires.
WARNING

WARNING: If your vehicle is fitted with wheel trims, remove them before fitting snow chains.
WARNING

WARNING: If you choose to install snow tires on your vehicle, they must be the same size, construction, and load range as the original tires listed on the tire placard, and they must be installed on all four wheels. Mixing tires of different size or construction on your vehicle can adversely affect your vehicle's handling and braking, and may lead to loss of vehicle control.

Only use snow chains on rear wheels. Install snow chains in pairs. Do not use self-tensioning snow chains.

Only use snow chains on the following specified tire sizes:

255/70R16Only install chains that are 15 mm or less.

255/75R17Only install chains that are 15 mm or less.

We recommend you use steel wheels of the same size and specification if snow chains are required because chains may chip aluminum wheels.

Follow these guidelines when using snow tires and traction devices:

If possible, avoid fully loading your vehicle.
Purchase snow chains from a manufacturer that clearly labels body to tire dimension restrictions.
When driving with snow chains do not exceed 30 mph (50 km/h) or the maximum speed recommended by the chain manufacturer, whichever is less.
Drive cautiously. If you hear the snow chains rub or bang against the vehicle, stop and tighten them. If this does not work, remove the snow chains to prevent vehicle damage.
Remove the snow chains when they are no longer needed. Do not use snow chains on dry roads.
If a temporary spare wheel is mounted on your vehicle, do not use snow chains on the axle with the temporary spare wheel.

Use snow chains that fit against the sidewall of the tire to prevent the chains from touching the wheel rims or suspension, see following illustration above.

If you have any questions regarding snow chains, please contact your authorized dealer.
