5-2. Steps to take in an emergency
*1: Driver's seat belt reminder:
The driver’s seat belt reminder sounds to alert the driver that his or her seat
belt is not fastened. Once the engine switch is turned to the ON or START
position, the buzzer sounds for 6 seconds. If the vehicle has reached a
speed of at least 12 mph (20 km/h), the buzzer sounds intermittently for 10
seconds. Then, if the seat belt is still unfastened, the buzzer will sound in a
different tone for 20 more seconds.
*2:Front passenger’s seat belt reminder:
The front passenger’s seat belt reminder sounds to alert the front passenger
that his or her seat belt is not fastened. The buzzer sounds intermittently for
10 seconds after the vehicle has reached a speed of at least 12 mph (20 km/
h). Then, if the seat belt is still unfastened, the buzzer will sound in a different
tone for 20 more seconds.

298 5-2. Steps to take in an emergency
nKey reminder buzzer
The buzzer indicates that the key has not been removed (with the engine
switch in the ACC or LOCK position and the driver’s door opened).
n Light reminder buzzer
The buzzer indicates that the headlight switch is left on (with the key
removed and the driver’s door opened).
n If the malfunction indicator lamp comes on while driving
First check the following:
l Is your vehicle low on gas?
If it is, refuel the vehicle immediately.
l Is the fuel tank cap loose?
If it is, tighten it securely.
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.
n Front passenger detect ion 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.
n
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level.
nThe tire pressure warning light ma y 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 a few minutes.
nWhen a tire is replaced with a compact spare tire
The compact spare tire is not equipped with the tire pressure warning
valve and transmitter. If a tire goes flat, the warning light will not turn off
even though the flat tire is replac ed with the compact spare tire. Replace
the compact 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.

5-2. Steps to take in an emergency
nIf the tire pressure warning system is inoperative
The tire pressure warning system will become inoperative in the follow-
ing conditions:
(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 become inoperative in the follow-
ing conditions:
(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 turned 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. 230)
n Customization that can be co nfigured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features →P. 351)

CAUTION
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 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 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.
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 tire 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.
