7-2. Steps to take in an emergency

■

When the tire pressure warning light comes on

Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured:



P. 493

If the tire is not punctured:

Carry out the following procedure after the tire temperature has lowered

sufficiently.

●

Check the tire inflation pressure and adjust to the appropriate level.

●

If the warning light does not go out even after several minutes, check

that the tire inflation pressure is at the specified level and carry out ini-

tialization. (



P. 429)

The warning light may come on again if the above operations are con-

ducted without first allowing the tire temperature to lower sufficiently.

■

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



Vehicles without P245/60R20 tires

The 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 inflation pressure.

The tire pressure warning light will go off after a few minutes.



Vehicles with P245/60R20 tires

The spare tire is also equipped with a 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, the tire pressure warn-

ing 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 inflation pressure. The tire pressure warning light will go off after a few

minutes.

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 transmitters

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/cm

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

●

Vehicles with P245/60R20 tires: If the spare tire is in a location subject

to poor radio wave signal reception

●

Vehicles with P245/60R20 tires: If a large metallic object which can

interfere with signal reception is put in the luggage compartment

■

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 engine switch is turned on, have it checked by your

Toyota dealer.

■

Customization that can be configured at Toyota dealer

The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features



P. 549) However, Toyota recommends that the seat

belt reminder buzzer be operational to alert the driver and front passenger
when seat belts are not fastened.

WARNING

■

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 dif-

ferent 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) 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).

WARNING

Your vehicle has also been equipped with a TPMS (tire pressure warn-

ing system) malfunction indicator to indicate when the system is not

operating properly. The TPMS (tire pressure warning system) malfunc-

tion 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 illumi-

nated. This sequence will continue upon subsequent vehicle start-ups

as long as the malfunction exists. When the malfunction indicator is illu-

minated, the system may not be able to detect or signal low tire pres-

sure as intended.
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

■

To ensure the tire pressure warning system operates properly

Do not install tires with different specifications or makers, as the tire

pressure warning system may not operate properly.
