KEYS AND DOORS NOTICE D Do not use liquid sealants for a flat tire as air pressure sensors will be damaged. D Take due care not to go over a curb stone and be careful of the dents 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 repaired or replaced, have them repaired or 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 air pressure sensors as well. Vehicles with standard tires: If the warning light is on, the tire pressure is lower than specified. Immediately stop your vehicle and check that the tire pressure is as specified on the tire pressure label. The air pressure gauge is located in the tool bag. If the warning light comes on or blinks even after tire pressure adjustment, it is probable that you may be a flat tire. If the tire goes flat, change to the spare tire. (See page 241). The spare tire is not equipped with the tire pressure sensor. So, the warning light remains on even if the spare tire is mounted. If the warning light does not go off more than 15 minutes after air is put in the deflated tire, the system might be malfunctioning. Consult your Lexus dealer. If you drive over about 180 km/h (112 mph) with the tires not inflated at the designated pressure for high speed driving, the warning light may turn on. If the tires are at the designated pressure for ordinary speed driving, decreasing the speed will turn off the warning light. (For the designated pressure for high speed driving, see "Specifications" on page 302.) 219 SC430 through December 2001 Production
