240 STARTING AND OPERATING SELF-SEALING TIRES - IF EQUIPPED A non-hardening viscous sealant applied to the inner liner of each tire fills punctures up to 0.19 in. (5 mm) to minimize the loss of air pressure. This contributes to the safety of the vehicle by significantly reducing the probability of a roadside stop due to a flat tire. TIRE CHAINS Use only compact chains, or other traction aids that meet SAE type "Class S" specifications. Chains must be the proper size for the vehicle, as recommended by the chain manufacturer. NOTE: Do not use tire chains on a compact spare tire. CAUTION! To avoid damage to your vehicle or tires, observe the following precautions: • Because of restricted chain clearance between tires and other suspension components, it is important that only chains in good condition are used. Broken chains can cause serious damage. Stop the vehicle immediately if noise occurs that could indicate chain breakage. Remove the damaged parts of the chain before further use. • Install chains on the rear wheels as tightly as possible and then retighten after driving about 1⁄2 mile (0.8 km). • Do not exceed 30 mph (48 km/h). • Drive cautiously and avoid severe turns and large bumps, especially with a loaded vehicle. • Use on Rear Wheels only. • Do not drive for prolonged period on dry pavement. • Observe the tire chain manufacturer's instructions on the method of installation, operating speed, and conditions for use. Always use the lower suggested operating speed of the chain manufacturer if different from the speed recommended by the manufacture.
