GAUGES, METERS AND SERVICE REMINDER INDICATORS Vehicles with run-flat 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 you cannot verify the tire pressure soon, go to the nearest Lexus dealer or authorized tire dealer at the moderate speed and do not ever exceed 90 km/h (55 mph) and have all your vehicle's tires checked and adjusted. And whether there is a flat tire or not should be also checked at this time. If any tire must be replaced, see "If you have a flat tire" on page 239. If the warning light does not go off more than 15 minutes after the tire pressure is adjusted, 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, take your vehicle to the nearest Lexus dealer, 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. If the warning light blinks and chimes sound every few minutes, the tire pressure is very low. Decrease your speed as soon as possible and call a Lexus dealer, Roadside Assistance or Customer Service Assistance (see"Foreword"). And take your vehicle to the nearest Lexus dealer or authorized tire dealer at a speed below 90 km/h (55 mph). When you drive your vehicle after the low tire pressure warning light blinks and chimes sound, the tire must be replaced. Do not use the repaired tire. 48
