08 SIENNA_U (L/O 0801) Replacing wheels CAUTION 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. WHEN TO REPLACE YOUR WHEELS If you have wheel damage such as bending, cracks or heavy corrosion, the wheel should be replaced. If you fail to replace a damaged wheel, the tire may slip off the wheel or cause loss of handling control. WHEEL SELECTION When replacing wheels, care should be taken to ensure that the wheels are replaced by ones with the same load capacity, diameter, rim width, and offset. This must be observed on compact spare tires, too. Correct replacement wheels are available at your Toyota dealer. A wheel of a different size or type may adversely affect handling, wheel and bearing life, brake cooling, speedometer/odometer calibration, stopping ability, headlight aim, bumper height, vehicle ground clearance, and tire or snow chain clearance to the body and chassis. D Do not exceed 50 km/h (30 mph) or the chain manufacturer's recommended speed limit, whichever is lower. D Drive carefully avoiding bumps, holes, and sharp turns, which may cause the vehicle to bounce. D Avoid sharp turns or locked−wheel braking, as use of chains may adversely affect vehicle handling. 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 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. NOTICE Do not attempt to use a tire chain on the compact spare tire, as it may result in damage to the vehicle as well as the tire. D The tire pressure warning valve and transmitter nuts should always be tightened to a torque of 4 N·m (0.4 kgf·m, 2.9 ft·lbf). D The use of non−genuine wheels may result in the tire pressure warning system failure or air −leak. 532 2008 SIENNA from Aug. '08 Prod. (OM45455U)
