*1: Open door warning buzzer:

The open door warning buzzer sounds to alert one or more of the doors is not fully closed (with the vehicle having reached a speed of 3 mph [5 km/h]).

*2: Seat belt warning buzzer:

The driver’s and front passenger’s seat belts reminder sounds to alert the driver and front passenger that his or her seat belt is not fastened. The buzzer sounds intermittently for 10 seconds after the vehicle has reached a speed of at least 12 mph (20 km/h). Then, if the seat belt is still unfastened, the buzzer will sound in a different tone for 20 more seconds.

■SRS warning light

This warning light system monitors the airbag sensor assembly, front impact sensors, side impact sensors (front), side impact sensors (rear), driver’s seat position sensor, driver’s seat belt buckle switch, front passenger occupant classification system (ECU and sensors), “AIR BAG ON” indicator light, “AIR BAG OFF” indicator light, front passenger’s seat belt buckle switch, seat belt pretensioner assemblies, airbags, interconnecting wiring and power sources. (→P. 140)

■Front passenger occupant classification system (ECU and sensors),

seat belt reminder and warning buzzer ●If luggage is placed on the front passenger seat, the front passenger occupant classification system (ECU and sensors) may cause the warn- ing light to flash and the warning buzzer to sound even if a passenger is not sitting in the seat.

●If a cushion is placed on the seat, the front passenger occupant classifi- cation system (ECU and sensors) may not detect a passenger, and the warning light may not operate properly.

5-2. Steps to take in an emergency

■Electric power steering system warning light

When the 12-volt battery charge becomes insufficient or the voltage tempo- rarily drops, the electric power steering system warning light may come on.

■If the malfunction indicator lamp comes on while driving

First check the following: ●Is the fuel tank cap loose?

If it is, tighten it securely.

The malfunction indicator lamp will go off after several driving trips. If the malfunction indicator lamp does not go off even after several trips, con- tact your Toyota dealer as soon as possible.

■When the tire pressure warning light comes on

Check the tire inflation pressure and adjust to the appropriate level. Pushing the tire pressure warning reset switch will not turn off the tire pressure warning light.

■The tire pressure warning light may come on due to natural causes The tire pressure warning light may come on due to natural causes such as natural air leaks and tire inflation pressure changes caused by tem- perature. In this case, adjusting the tire inflation pressure will turn off the warning light (after a few minutes).

■When a tire is replaced with a spare tire

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 repaired tire and adjust the tire infla- tion pressure. The tire pressure warning light will go off after a few min- utes.

501

5-2. Steps to take in an emergency

■If the tire pressure warning system is not functioning

The tire pressure warning system will be disabled in the following condi- tions: (When the condition becomes normal, the system will work properly.) ●If tires not equipped with tire pressure warning valves and transmit-

ters are used

●If the ID code on the tire pressure warning valves and transmitters is

not registered in the tire pressure warning computer

●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or

higher

The tire pressure warning system may be disabled in the following condi- tions: (When the condition becomes normal, the system will work properly.) ●If electronic devices or facilities using similar radio wave frequencies

are nearby

●If a radio set at a similar frequency 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, particularly around the

wheels or wheel housings

●If non-genuine Toyota wheels are used (Even if you use Toyota wheels, the tire pressure warning system may not work properly with some types of tires.) ●If tire chains are used

502

5-2. Steps to take in an emergency

■If the tire pressure warning light frequently comes on after blinking

for 1 minute If the tire pressure warning light frequently comes on after blinking for 1
minute when the “POWER” switch is turned to ON mode, have it checked by your Toyota dealer.

■Customization

The vehicle speed linked seat belt reminder buzzer can be disabled. (Customizable features →P. 590) However, Toyota recommends that the seat belt reminder buzzer be operational to alert the driver and front passen- ger when seat belts are not fastened.

CAUTION

■If both the ABS and the brake system warning lights remain on

Stop your vehicle in a safe place immediately and contact your Toyota dealer. The vehicle will become extremely unstable during braking, and the ABS system may fail, which could cause an accident resulting in death or serious injury.

■When the electric power steering system warning light comes on

The steering wheel may become extremely heavy. If the steering wheel becomes heavier than usual when operating, hold firmly and operate using more force than usual.

503

5-2. Steps to take in an emergency

CAUTION

■If the tire pressure warning light comes on

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. ●Stop 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 pres- sure adjustment, it is probable that you have a flat tire. Check the tires. If a tire is flat, change it with 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.

■If a blowout or sudden air leakage should occur

The tire pressure warning system may not activate immediately.

■Maintenance of the tires

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 differ- ent 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.)

504

5-2. Steps to take in an emergency

CAUTION

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) illumi- nates, 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 sub- stitute 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 operat- ing properly. The TPMS (tire pressure warning system) malfunction indi- cator 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 illumi- nated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illumi- nated, the system may not be able to detect or signal low tire pressure as intended.

505

5-2. Steps to take in an emergency

CAUTION

TPMS (tire pressure warning system) malfunctions may occur for a vari- ety 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 pres- sure warning system) malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alter- nate tires and wheels allow the TPMS (tire pressure warning system) to continue to function properly.

NOTICE

■Precaution when installing a different tire

When a tire of a different specification or maker is installed, the tire pres- sure warning system may not operate properly.
