07 12.25 Replacing wheels TIRE CHAIN SELECTION Use the tire chains of correct size. Regulations regarding the use of tire chains vary according to location or type of road, so always check local regulations before installing chains. CHAIN INSTALLATION Install the chains on the rear tires as tightly as possible. Do not use tire chains on the front tires. Retighten chains after driving 0.5-1.0 km (1/4-1/2 mile). When installing chains on your tires, carefully follow the instructions of the chain manufacturer. If wheel covers are used, they will be scratched by the chain band, so remove the covers before putting on the chains. D Avoid sharp turns or locked−wheel braking, as use of chains may adversely affect vehicle handling. As you might have difficulty in identifying a flat or deflated tire, a tire pressure warning system is provided on this vehicle. When replacing the wheels, be sure to install tire pressure warning valves and transmitters on the wheels. Consult your Toyota dealer about how to set up the tire pressure warning valves and transmitters. D When driving with chains installed, be sure to drive carefully. Slow down before entering curves to avoid losing control of the vehicle. Otherwise an accident may occur. CAUTION D Have the tires, wheels or tire pressure warning valves and transmitters replaced and ID codes registered by Toyota dealer. If you need tire pressure warning valves and transmitters, purchase from Toyota dealer. D The tire pressure warning valve and transmitter nuts should always be tightened to a torque of 4 N·m (0.4 kg·fm, 2.9 ft·lbf). CAUTION D Do not exceed 50 km/h (30 mph) or the chain manufacturer's recommended speed limit, whichever is lower. D The use of non−genuine wheels may result in the tire pressure warning system failure or air −leak. D Drive carefully avoiding bumps, holes, and sharp turns, which may cause the vehicle to bounce. 447
