â– If the malfunction indicator lamp comes on while driving
First check the following:
The light will go off after several driving trips.
If the light does not go off even after several trips, contact your Toyota dealer as soon as possible.
â– Electric power steering system warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily drops, the electric power steering system warning light may come on and the warning buzzer may sound.
â– When the tire pressure warning light comes on (vehicles with tire pressure warning system)
Inspect the tires to check if a tire is punctured.
If none of the tires are punctured: Turn the engine switch to OFF then turn it to ON. Check if the tire pressure warning light comes on or blinks.
If the tire pressure warning light blinks for approximately 1 minute then stays on
There may be a malfunction in the tire pressure warning system. Have the vehicle inspected by your Toyota dealer immediately.
If the tire pressure warning light comes on
1. After the temperature of the tires has lowered sufficiently, check the inflation pressure of each tire and adjust them to the specified level.
2. If the warning light does not turn off even after several minutes have elapsed, check that the inflation pressure of each tire is at the specified level and perform initialization.
â– The tire pressure warning light may come on due to natural causes (vehicles with tire pressure warning system)
The tire pressure warning light may come on due to natural causes such as natural air leaks and tire inflation pressure changes caused by temperature.
In this case, adjusting the tire inflation pressure will turn off the warning light (after a few minutes).
â– When a tire is replaced with a compact spare tire (vehicles with tire pressure warning system)
The compact spare tire is not equipped with a tire pressure warning valve and transmitter. If a tire goes flat, the tire pressure warning light will not turn off even though the flat tire has been replaced with the spare tire. Replace the spare tire with the standard tire and adjust the tire inflation pressure. The tire pressure warning light will go off after a few minutes.
WARNING
â– If a warning light comes on or a warning buzzer sounds when a warning message is shown on the multi-information display*
Check and follow the message shown on the multi-information display.
Failure to do so may result in death or serious injury.
*: Warning lights illuminate in red or yellow and the warning buzzer beeps once or sounds continuously.
â– When the electric power steering system warning light comes on
When the light comes on yellow, the assist to the power steering is restricted. When the light comes on red, the assist to the power steering is lost and handling operations of the steering wheel become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold firmly and operate using more force than usual.
â– If the tire pressure warning light comes on (vehicles with tire pressure warning system)
Be sure to observe the following precautions. Failure to do so could cause a loss of vehicle control and result in death or serious injury.
Adjust the tire inflation pressure immediately.
â– If a blowout or sudden air leakage should occur (vehicles with tire pressure warning system)
The tire pressure warning system may not activate immediately.
â– Maintenance of the tires (vehicles with tire pressure warning system)
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 (tire pressure warning light) when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale (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 (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system) malfunction indicator to indicate when the system is not operating properly.
The TPMS (tire pressure warning system) malfunction indicator is combined with the low tire pressure telltale (tire pressure warning light). When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated.
This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS (tire pressure warning system) from functioning properly. Always check the TPMS (tire pressure warning system) malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS (tire pressure warning system)
NOTICE
â– To ensure the tire pressure warning system operates properly (vehicles with tire pressure warning system)
Do not install tires with different specifications or makers, as the tire pressure warning system may not operate properly.
