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 temper-
ature. In this case, adjusting the ti
re 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 inflation
pressure. The tire pressu re warning light will go off after a few minutes.
■Conditions that the tire pressure warning system may not function
properly
The tire pressure warn ing system will be disabled in the following condi-
tions:
(When the condition be comes 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/cm2 or bar) or
higher
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition be comes 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

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 turn
ed to ON mode, have it checked by
your Toyota dealer.
■ Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or an
audio sound.
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 extrem ely unstable during braking, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
■ Electric power steering warning light (warning buzzer)
When the 12-volt battery charge becomes in sufficient or the voltage tempo-
rarily drops, the electric power steering warning light may come on and the
warning buzzer may sound.
■ When the electric power steerin g system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavie r than usual when operating, hold
firmly and operate using more force than usual.
■
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 th e 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.

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 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-ti re pressure warning system) that
illuminates a low tire pre ssure 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 effi ciency and tire tread life, and may
affect the vehicle’s hand ling and stopping ability.
Please note that the TPMS (tire pres sure warning system) is not a sub-
stitute for proper ti re maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached
the level to trigger illumina tion of the TPMS low tire pressure telltale (tire
pressure warning light).
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 lo w tire pressure telltale (tire pressure
warning light). When the system dete cts a malfunction, the telltale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue up on 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.

■The compact spare tire
●The compact spare tire is identified by the label “TEMPORARY USE
ONLY” on the tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.
●Make sure to check the tire inflation pressure of the compact spare tire.
( P. 459)
■After completing the tire change
The tire pressure warning system must be reset. ( P. 364)
■When using the compact spare tire
As the compact spare tire is not equipped with a tire pressure warning
valve and transmitter, lo w inflation pressure of the spare tire will not be
indicated by the tire pressure warning system. Also, if you replace the
compact spare tire after the tire pressure warning light comes on, the light
remains on.
■When the compact spare tire is equipped
The vehicle becomes lower when driving with the compact spare tire
compared to when driving with standard tires.
■If you have a flat front tire on a road covered with snow or ice
Install the compact spare tire on one of the rear wheels of the vehicle.
Perform the following steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the vehi-
cle.
Fit tire chains to the front tires.
