If the malfunction indicator lamp comes on while driving
First check the following:
●Is the fuel tank empty?
If it is, fill the fuel tank immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after several driving trips.
If the light does not go off even after several trips, contact your Toyota dealer
as soon as possible.
■ When the tire pressure warning light comes on
Inspect the appearance of the tire to check that the tire is no t punctured.
If the tire is punctured: P. 492
If the tire is not punctured:
Carry out the following procedure after the tire temperature ha s lowered suffi-
ciently.
● 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 initialization.
( P. 422)
The warning light may come on again if the above operations are conducted
without first allowing the tire temperature to lower sufficient ly.
■
The tire pressure warning light may come on due to natural caus es
The tire pressure warning light may come on due to natural caus es such
as natural air leaks and tire inflation pressure changes caused by tem-
perature. In this case, adjusting the tire inflation pressure w ill turn off the
warning light (afte r a few minutes).
■When a tire is replace d with a spare tire
Vehicles without P245/60R20 tires
The spare tire is not equipped with a tire pressure warning val ve and
transmitter. If a tire goes flat, the tire pressure warning lig ht 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 press ure 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 va lve 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 spar e tire with the repaired tire and adjust the
tire inflation pressure. The t ire pressure warning light will go off after a few
minutes.

If the tire pressure warning system is not functioning
The tire pressure warning syst
em will be disabled in the follow ing condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If tires not equipped with tire pressure warning valves and tra nsmitters
are used
●If the ID code on the tire pressure warning valves and transmit ters is not
registered in the tire pr essure 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 followi ng condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If electronic devices or facilitie s 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 som e types
of tires.)
●If tire chains are used
●Vehicles with P245/60R20 tires: If the spare tire is in a locat ion subject
to poor radio wave signal reception
●Vehicles with P245/60R20 tires : If a large metallic object whic h can
interfere with signal reception is put in the luggage compartme nt
■If the tire pressure warning light frequently comes on after bl inking
for 1 minute
If the tire pressure warning light frequently comes on after bl inking 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 disab led.
(Customizable features P. 547) However, Toyota recommends that the seat
belt reminder buzzer be operational to alert the driver and fro nt 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 t he tire
inflation pressure immediately.
●If the tire pressure warning light comes on even after tire inf lation pres-
sure adjustment, it is probable that you have a flat tire. Chec k the tires.
If a tire is flat, change it with the spare tire and have the f lat tire
repaired by the nearest Toyota dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires dete riorate,
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 p ressure
label (tire and load information label). (If your vehicle has t ires of a dif-
ferent size than the size indica ted on the vehicle placard or tire inflation
pressure label [tire and load information label], you should de termine
the proper tire inflation p ressure 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. Acco rdingly,
when the low tire pressure telltale (tire pressure warning ligh t) 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 lif e, and may
affect the vehicle’s handl ing and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintena nce, 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 indicato r to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) mal func-
tion indicator is combined with the low tire pressure telltale (tire pressure
warning light). When the system detects a malfunction, the tell tale will
flash for approximately one mi nute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle star t-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 tir e pres-
sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installation of replacement or al ternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure w arning
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 sys tem) to
continue to function properly.
NOTICE
■To ensure the tire pressure warning system operates properly
