2002 Lexus SC 430 User Guide 1 - Page 54

GAUGES, METERS AND SERVICE REMINDER INDICATORS Vehicles with standard tires: If the warning light is on, the tire pressure is lower than specified. Stop your vehicle at a safe place as soon as possible 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 have 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 306.) CAUTION If the warning light comes on, observe the following instructions: D Decrease the speed as soon as possible. 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. 50
