Maintenance and Specifications • Do not install chains on the front wheels. Chains on the front wheels may interfere with suspension components. • Chains are not recommended for use on the optional P275/65R18 tire. • Install chains securely, verifying that the chains do not touch any wiring, brake lines or fuel lines. • Drive cautiously. If you hear the chains rub or bang against your vehicle, stop and re-tighten the chains. If this does not work, remove the chains to prevent damage to your vehicle. • If possible, avoid fully loading your vehicle. • Remove the tire chains when they are no longer needed. Do not use tire chains on dry roads. • The suspension insulation and bumpers will help prevent vehicle damage. Do not remove these components from your vehicle when using snow tires and chains. • Do not exceed 48 km/h (30 mph) with tire chains on your vehicle.
