GAUGES, METERS AND SERVICE REMINDER INDICATORS Vehicles with standard tires: If the warning light is on, the tire inflation pressure is lower than specified. Stop your vehicle at a safe place as soon as possible and check that the tire inflation pressure is as specified on the tire and loading information label. The tire pressure gauge is located in the tool bag. If the warning light comes on or blinks even after tire inflation pressure adjustment, it is probable that you have a flat tire. If the tire goes flat, change to the spare tire. (See page 247). 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 the warning light blinks and chimes sound every few minutes, the tire inflation pressure is very low. Stop your vehicle at a safe place as soon as possible and check that the tire inflation pressure is as specified on the tire and loading information label. The tire pressure gauge is located in the tool bag. Locate the deflated tire and change to the spare tire. For the procedure for changing the tire, see "If you have a flat tire (Vehicles with standard tires)" on page 247. The spare tire is not equipped with the tire pressure sensor. So, the warning light remains on even if the spare tire is mounted. CAUTION If the warning light blinks and chimes sound, 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. D The warning system may not activate immediately if bursts or sudden air leakage should occur. 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.
