04 SIENNA_U (L/O 0408) Run −flat tires When rotating tires, check for uneven wear and damage. Abnormal wear is usually caused by incorrect tire pressure, improper wheel alignment, out − of −balance wheels, or severe braking. CAUTION Do not include a compact spare tire when rotating the tires. It is designed for temporary use only. Initial adjustment of the tire pressure warning system is necessary after you have rotated your tires. See "Tire pressure warning system" on page 188 in Section 1 −6. Some vehicles are equipped with run −flat (RFT) tires. The run −flat tire allows you to continue driving for up to 160 km (100 miles) at a speed below 90 km/h (55 mph) even if any tire goes flat. However, in some conditions (such as high temperatures), you could not continue driving for up to 160 km (100 miles). When the tire goes flat or when the tire pressure is below 100 kPa (1.0 kgf/cm2 or bar, 15 psi), the tire must be replaced. If you are not sure, consult your Toyota dealer. Do not use the repaired tire. There is an "RFT" or "DSST" mark on the sidewall of the run −flat tire. If you cannot distinguish between the standard tire and run −flat tire, consult your Toyota dealer. The tire warranty book provides detailed information on the run −flat tires. For details, see the tire warranty book. CAUTION D Do not use non −genuine wheels, as this may cause dangerous handling characteristics resulting in loss of control. D Do not use the run −flat tires equipped on your vehicle on another model. These tires are especially for this model. D Do not mix run −flat tires with standard tires. 469 2004 SIENNA from Aug.
