5-2. Steps to take in an emergency
The light will go off after taking several driving trips.
If the light does not go off even after several trips, contact your Toyota dealer
as soon as possible.
■ Front passenger detection sensor and passenger seat belt reminder
If luggage or other load is placed on the front passenger seat, depending on
its weight, the reminder light to flash and buzzer to sound.
■
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
warning light (after several minutes).
■When a tire is replaced with a spare tire
The temporary 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 temporary spare
tire. Replace the temporary spare tire with the repaired tire and adjust
the proper tire inflatio n pressure. The tire pres sure warning light will turn
off after several minutes.
■If the tire pressure warning system is inoperative
The tire pressure warning 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 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.
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.

524 5-2. Steps to take in an emergency
●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 tire pressure warning light comes on after blinking for 1
minute frequently
If the tire pressure warning light comes on after blinking for 1 minute fre-
quently when the engine switch is turned to the ON position, have it
checked by your Toyota dealer.
■ After changing the engine oil (U.S.A. only)
Make sure to reset the oil maintenance data. ( P. 455)
■ Customization that can be co nfigured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features P. 584)
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 tire
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 handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire ma intenance, 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 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.

538 5-2. Steps to take in an emergency
Firmly tighten each nut two or
three times in the order shown in
the illustration.
Tightening torque:
154 ft·lbf (209 N·m, 21.3 kgf·m)*
*
: When used on aluminum wheel, apply 97 ft·lbf (131
N·m, 13.4 kgf·m)
Stowing the flat tire, jack and all tools
Remove tne center wheel ornament by pushing from the
reverse side.
Lay down the tire with the outer side facing up, and install the
holding bracket.
Then secure the tire, taking care that the tire goes straight up
without catching on any other part, to prevent it from flying for-
ward during a collisi on or sudden braking.
Keep winding until three clicks are heard.
Stow the tools and jack securely.
■After completing the tire change
The tire pressure warnin g system must be reset. ( P. 467)
■When using the temporary spare tire
As the temporary spare tire is not equipped with the tire pressure warn-
ing valve and transmitter, low inflation pressure of the spare tire will not
be warned. Also, if you replace the temporary spare tire after the tire
pressure warning light comes on, the light remains on.
