07 SIENNA_U (L/O 0612) Installing snow tires and chains D Avoid abrupt steering wheel maneuvering and braking. If the vehicle tires deteriorate, you could lose control of the steering wheel or the brakes, causing death or serious injury. D Do not replace or repair the tire by yourself. When the tires must be replaced or repaired, consult your Toyota dealer or authorized tire dealer. NOTICE WHEN TO CHAINS USE SNOW TIRES OR z Take due care not to go over a curb stone and be careful of the holes in the road because deflated tire pressure affects tire cushion performance. The wheels, tires, body, suspension and other components could be damaged. z Your ground clearance is reduced if the run−flat tire goes flat so avoid driving over obstacles and drive slowly on rough, unpaved roads and speed bumps. Also, do not attempt to go through an automatic car wash as the vehicle may get caught, resulting in damage. Snow tires or chains are recommended when driving on snow or ice. On wet or dry roads, conventional tires provide better traction than snow tires. SNOW TIRE SELECTION If you need snow tires, select tires of the same size, construction and load capacity as the originally installed tires. Also, on all−wheel drive models, all the tires must be the same brand and have the same tread patterns. Do not use tires other than those mentioned above. Do not install studded tires without first checking local regulations for possible restrictions. 494 2007 SIENNA from Oct. '06 Prod. (OM45437U)
