The warning system may not activate immediately if bursts or sudden air leakage should occur

The tire pressure warning light comes on when the ignition switch is set at ON and goes off after a few seconds. This means the tire pressure warning system is operating properly. If the tire inflation pressure becomes low, the light comes on again. In this case, adjusting the tire inflation pressure will turn off the light after a few minutes. If the light comes on after blinking for 1 minute, the tire pressure warning system is not working properly.

/l\ CAUTION

If the tire pressure warning light comes on, be sure to observe the following precautions. Failure to do so could cause loss of vehicle control and result in death or serious injury.

^S top your vehicle in a safe place as soon as possible. Adjust the tire inflation pressure immediately.

^If the tire pressure warning light comes on even after tire inflation pressure adjustment, it is probable that you have a flat tire. Check the tires. If the tire is flat, change to the spare tire and have the flat tire repaired by the nearest Toyota dealer.

^-Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could lose control of the steering wheel or the brakes.

The tire pressure warning light may turn on due to natural causes such as natural air leaks or tire inflation pressure changes caused by temperature. In this case, adjusting the tire inflation pressure will turn off the light.

Pushing the tire pressure warning reset switch should not turn off the tire pressure warning light. Adjusting the tire inflation pressure will turn off the light.

The spare tire (except compact spare tire) is also equipped with the tire pressure warning valve and transmitter. The tire pressure warning light will turn on if the tire inflation pressure of the spare tire is low. If a tire goes flat, even though the flat tire is replaced with the spare tire, the warning light does not turn off. Replace the spare tire with the repaired tire and adjust the proper tire inflation pressure. The tire pressure warning light will turn off after a few minutes.

The compact spare tire is not equipped with the tire pressure warning valve and transmitter. If a tire goes flat, the warning light will not turn off even though the flat tire is replaced with the spare tire. Replace the spare tire with the repaired tire and adjust the proper tire inflation pressure. The tire pressure warning light will turn off after a few minutes.

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label (tire and load information label). (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label (tire and load information label), you should determine the proper tire inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS-tire pressure warning system) that illuminates a low tire pressure telltale (low tire pressure warning light) when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale (low tire pressure warning light) illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.

Please note that the TPMS (tire pressure warning system) is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale (low tire pressure warning light).

NOTICE

♦ Do not use liquid sealants for a flat tire as tire pressure warning valve and transmitter will be damaged.

♦ When the tires must be repaired or replaced, have them repaired or replaced by the nearest Toyota dealer or authorized tire dealer. The tire pressure warning valves and transmitters will be affected by the installation or removal of tires.

IF THE TIRE PRESSURE WARNING LIGHT COMES ON AFTER BLINKING FOR 1 MINUTE...

If the tire pressure warning light comes on after blinking for 1 minute when the ignition switch is set at ON, the tire pressure warning system is not working properly.

The system will be disabled in the following conditions:

(When the condition becomes normal, the system will work properly.)

^ If tires not equipped with tire pressure warning valves and transmitters are used.

^ If the ID code on the tire pressure warning valves and transmitters is not registered.

^ If electronic devices or facilities using similar radio wave frequencies are nearby.

^ If a radio set at similar frequencies is in use in the vehicle.

^ If a window tint that affects the radio wave signals is installed.

^ If there is a lot of snow or ice on the vehicle, in particular around the wheels or wheel housings.

^ If non-genuine Toyota wheels are used.

^ If a special set of tires is used.

^ If tire chains are used.

^ If the spare tire (except compact spare tire) is in a location subject to poor radio wave signal reception.

^ If the tire inflation pressure is more than 500 kPa (5 kgf/cm2 or bar, 70 psi) or more higher than the specified level.

If the tire pressure warning light comes on after blinking for 1 minute frequently when the ignition switch is set at ON, have the system checked by your Toyota dealer.

Pushing the tire pressure warning reset switch should not turn off the tire pressure warning light.

Even if you use genuine wheels, the tire pressure warning system may not work properly with some types of tires.

REPLACING TIRES AND WHEELS

When replacing the tires and wheels, be sure to install tire pressure warning valves and transmitters. ID codes on the tire pressure warning valves and transmitters are registered on the tire pressure warning ECU. When replacing a tire pressure warning valve and transmitter, it is necessary to register the ID code of tire pressure warning valve and transmitter. Have the ID code registered by your Toyota dealer.

NOTICE

When the tires or tire pressure warning valves and transmitters must be replaced, have them replaced by your Toyota dealer. The tire pressure warning valves and transmitters will be affected by the installation or removal of tires.
