RWARNING Driving too fast for conditions creates the possibility of loss of vehicle control. Driving at very high speeds for extended periods of time may result in damage to vehicle components. Snow Tires and Chains The tires on your vehicle have all-weather treads that provide traction in rain or snow. However, during the winter months in some climates, you may need to use snow tires and occasionally chains for your tires. RWARNING Snow tires must be the same size and grade as the tires you currently have on your vehicle. Use chains on the tires only in an emergency or if the law requires them where you live. If you choose to use chains on your vehicle's tires, be aware of the following: u Make sure the chains are the right size for your tires. Use only SAE Class "S" chains. Other types may damage your vehicle. u Put the chains on tightly with the ends held down securely. Verify that no chain touches any wiring, brake lines, or fuel lines. Follow the chain manufacturer's instructions. u Drive slowly. If you can hear the chains rub or bang against your vehicle, stop the vehicle and tighten the chains. If you continue to hear the chains rub or bang against your vehicle, remove the chains to prevent damage to your vehicle. 292
