■Front passenger detect ion sensor and passenger seat belt reminder
If luggage is placed on the front passenger seat, the front passenger detec-
tion sensor may cause the warning light to flash, even if a passenger is not
sitting in the seat.
■
If the tire pressure warning system is inoperative
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 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.)
●If tire chains are used.
●If the spare tire is in a location subject to poor radio wave signal
reception.
●If a large metallic object which can in terfere with signal reception is
put in the trunk.

■If the tire pressure warning light continues to comes on after blink-
ing for 1 minute frequently
If the tire pressure warning light comes on after blinking for 1 minute
when the “ENGINE START STOP” switch
or the engine switch is turned
to ON mode, have it checked by your Toyota dealer.
■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 does not turn off the tire
pressure warning light.
■The tire pressure warning light may turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such
as natural air leaks or tire inflation pressure changes caused by temper-
ature. In this case, adjusting the ti re inflation pressure will turn off the
light (after a few minutes).
■When a tire is replaced with a 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.

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.
■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 pl acard 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 th e vehicle placard or tire inflation
pressure label [tire and load informa tion label], you should determine the
proper tire inflation pr essure for those tires.)
As an added safety feature, your v ehicle has been equipped with a tire
pressure monitoring system (TPMS-tire 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 pressu re 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 effi ciency and tire tread life, and may
affect the vehicle’s handling and stopping ability.

CAUTION
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire main
tenance, and 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).
Your vehicle has also been equipped with a TPMS (tire pressure warning
system) malfunction indicator to indi cate 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 detec ts 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 prev ent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction tellt ale 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.

three times in the order shown in
the illustration.
Tightening torque:

Reinstall the wheel ornament.
Stow the flat tire, tire jack and all tools.

■To store the jack
■After completing the tire change
The tire pressure warnin g system must be reset. ( P. 323)
STEP6
To store the jack, align the hole of the
jack head with the vehicle hook. Turn
the jack joint until the jack base fits
securely with the vehicle body. 
This prevents the jack from flying for-
ward during a collisio n or sudden stop.

NOTICE
■Do not drive the vehicle with a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a fl at tire can damage the tire and the
wheel beyond repair.
■When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your Toyota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled correctly.
■To avoid damaging the tire pressure warning valves and transmit-
ters
Do not use liquid sealants on flat tires.

■Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■ To prevent battery discharge
● Turn off the headlights and the audio system while the “ENGINE START
STOP” switch or the engine is turned off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
■ When the battery is removed or discharged
The following systems must be initialized.
● Power windows (
P. 66)
● Moon roof (
P. 70)
● Tire pressure warning system (
P. 324)
Start the engine of the second vehicle. Increase the engine
speed slightly and maintain at that level for approximately
five minutes to recharge the battery of your vehicle.
Vehicles with smart key system  Open and close any of
the doors with the “ENGINE START STOP” switch OFF.
Maintain the engine speed on the second vehicle and turn
the “ENGINE START STOP” switch or the engine switch to
the ON mode, then start the vehicle’s engine.
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Once the engine starts, have the vehicle checked at your Toyota
dealer as soon as possible.STEP2
