5-2. Steps to take in an emergency
nIf 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.)
lIf tires not equipped with tire pressure warning valves and transmit-
ters are used.
lIf the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure warning computer.
lIf 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.)
lIf electronic devices or facilities using similar radio wave frequencies
are nearby.
lIf a radio set at similar frequencies is in use in the vehicle.
lIf a window tint that affects the radio wave signals is installed.
lIf there is a lot of snow or ice on the vehicle, in particular around the
wheels or wheel housings.
lIf 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.)
lIf tire chains are used.
nIf 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 tu rned to the ON position, have it
checked by your Toyota dealer.
n After changing the engine oil (except Canada)
Make sure to reset the oil maintenance data. ( →P. 249)

nCustomization that can be co nfigured at Toyota dealer
l The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features →P. 369)
l The key reminder buzzer can be disabled.
(Customizable features →P. 369)
l The light reminder buzzer can be disabled.
(Customizable features →P. 369)
CAUTION
nIf 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.
lStop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
lIf the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is pr obable that you have a fl at 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.
lAvoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
nIf a blowout or sudden air leakage should occur
The tire pressure warning syste m may not activate immediately.
nMaintenance 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 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 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.)

5-2. Steps to take in an emergency
CAUTION
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 telltale (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 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 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 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.

5-2. Steps to take in an emergency
Loosen the center fastener that
secures the spare tire.
n Comp
act spare tire
The compact spare tire saves space in your luggage compartment,
and
its lighter weight helps to enhance fuel economy and permits
easier installation in case of a flat tire.
The compact spare tire is
d
esigned for temporary emer -
gency use only.
The compact spare tire is identi -
fied by the distinctive wording
“TE

MPORARY USE ONLY”
molded into the sidewall of the
tire.
nWhen using the compact spare tire
As the compact spare tire is not equipped with the tire pressure warning
valve and trans
mitter, low inflation pr essure of the compact spare tire will
not be warned. Also, if you replace the compact spare tire after the tire
pressure warning light comes on, the light remains on.
nCheck the tire inflation pressure of the compact spare tire.

n
Overheating
If you observe the following, your vehicle may be overheating.
lThe high
engine coolant temperature warning light flashes or comes on
or a loss of power is experienced.
l Steam is coming from under the hood.
CAUTION
nTo prevent an accident or injury when inspecting un der the hood of
your vehicle
l If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injury such as burns.
l Keep hands and clothing away from the fan and other belts while the
engine is running.
l Do not loosen the radiator cap while the engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
NOTICE
n When adding engine coolant
Wait until the engine has cooled down before adding engine coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot engine too
quickly can cause damage to the engine.
