■When a tires is replaced with a spare tire
Vehicles with a compact spare tire
The compact spare tire is not equipped with the 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 is replaced with the spare tire.
Replace the spare tire with the repair ed tire and adjust the proper tire
inflation pressure. The ti re pressure warning light will turn off after a few
minutes.
Vehicles with a full-size spare tire
The spare tire is also equipped with the tire pressure warning valve and
transmitter. The tire pressure warning li ght 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 tire pressure warning light does
not turn off. Replace the spare tire with the repaired tire and adjust the
proper tire inflation pressure. The ti re pressure warning light will turn off
after a few minutes.
■If the tire pressure warning system is inoperative
The tire pressure warning system may become inoperative in the follow-
ing conditions:
(When the condition be comes 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 electronic devices or facilities using similar radio wave frequencies
are nearby.
●If a large metallic object which can interfere with signal reception is
put in the trunk
●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. (Even if you use Toyota
wheels, the tire pressu re warning system may not work properly with
some types of tires.)

388 5-2. Steps to take in an emergency
●If tire chains are used
●If the spare tire is in a location subject to poor radio wave signal
reception
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher.
■If the tire pressure warning light comes on after blinking frequently
for 1 minute
If the tire pressure warning light comes on after blinking frequently for 1
minute when the “ENGINE START STOP” switch or engine switch is
turned ON, have it checked by your Toyota dealer.
■ Customization that can be co nfigured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features P. 454) However, Toyota recommends that the
seat belt reminder buzzer be operational to alert the driver and front passen-
ger that the seat belts are not fastened.
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 re sult 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 pr obable 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.
■If a blowout or sudden air leakage should occur
The tire pressure warning syste m may not activate immediately.

CAUTION
■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 pr essure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-ti re pressure warning system) that
illuminates a low tire pressure telltal e (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pre ssure 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 effi ciency and tire tread life, and may
affect the vehicle's hand ling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper ti re maintenance, an d it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illu mination of the TPMS low ti re pressure telltale (tire
pressure warning light).

CAUTION
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 det ects a malfunction, the telltale will
flash for approximately one minute an d then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indi cator is illumi-
nated, 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 vari-
ety of reasons, including the installati on 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 te lltale 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.
