2006 Lexus GS 300 Owners Manual - Page 459

STARTING AND DRIVING CAUTION If the low tire pressure warning light comes on, take your vehicle to the nearest Lexus dealer or authorized tire dealer or gas station as soon as possible, observing the following instructions: D Decelerate as soon as possible to the most appropriate speed that conditions permit. Do not drive over 90 km/h (55 mph). 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 The warning system may not activate immediately if bursts or sudden air leakage should occur. When the tyre pressure warning system warning light is lit, one or more of your tyres is significantly under−inflated. You should stop and check your tyres as soon as possible, and inflate them to the proper pressure as indicated on the vehicle's tyre information placard. Driving on a significantly under−inflated tire causes the tyre to overheat and can lead to tyre failure. Under−inflation also reduces fuel efficiency and tyre tread life, and may affect the vehicle's handling and stopping ability. Each tyre, including the spare, should be checked monthly when cold and set to the recommended inflation pressure as specified in the vehicle placard and owner's manual. NOTICE D Do not use liquid sealants for a flat tire as tire pressure sensors will be damaged. D 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. D 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. D When the tires must be replaced, have them replaced by the nearest Lexus dealer or authorized tire dealer. The tire pressure sensor will be affected by the installation or removal of tires. D When the tires must be replaced, replace the grommets for tire pressure sensors as well. 435
