: Driver’s seat belt buzzer:

The driver’s seat belt buzzer sounds to alert the driver that his or her seat
belt is not fastened. Once the engine switch is turned to the “ON” position,
the buzzer sounds for 6 seconds. If the vehicle reaches a speed of 12 mph
(20 km/h), the buzzer sounds once. If the seat belt is still unfastened after 30
seconds, the buzzer will sound intermittently for 10 seconds. Then, if the
seat belt is still unfastened, the buzzer will sound in a different tone for 20
more seconds.

Tire pressure warning 
light

When the light comes on: 
Low tire inflation pressure 
such as
• Natural causes (

P. 313)

• Flat tire (

P. 318)

Adjust the tire inflation 
pressure to the specified 
level.

The light will turn off after 
a few minutes. In case the 
light does not turn off 
even if the tire inflation 
pressure is adjusted, 
have the system checked 
by your Scion dealer.

When the light comes on 
after blinking for approxi-
mately one minute:
Malfunction in the tire pres-
sure warning system 
(

P. 314)

Have the system checked

: Front passenger’s seat belt buzzer:

The front passenger’s seat belt buzzer sounds to alert the front passenger
that his or her seat belt is not fastened. The buzzer sounds once if the vehi-
cle reaches a speed of 12 mph (20 km/h). If the seat belt is still unfastened
after 30 seconds, the buzzer will sound intermittently for 10 seconds. Then,
if the seat belt is still unfastened, the buzzer will sound in a different tone for
20 more seconds.

■

Front passenger detection sensor and passenger seat belt reminder
and warning buzzer

●

If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash and warning
buzzer to sound, even if a passenger is not sitting in the seat.

●

If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.

■

When the tire pressure warning light comes on

Check the tire inflation pressure and adjust to the appropriate level.

■

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 tire 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 infla-
tion pressure. The tire pressure warning light will go off after a few min-
utes.

■

If the tire pressure warning system is inoperative

The tire pressure warning system will be disabled in the following condi-
tions:

(When the condition becomes 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.

●

If the tire inflation pressure is 55 psi (380 kPa, 3.87 kgf/cm

2

 or bar) or

higher.

The tire pressure warning system may be disabled in the following condi-
tions:

(When the condition becomes normal, the system will work properly.)

●

If electronic devices or facilities using similar radio wave frequencies
are nearby.

●

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 Scion wheels are used. (Even if you use Scion
wheels, the tire pressure warning system may not work properly with
some types of tires.)

●

If tire chains are used.

●

If a large metallic object which can interfere with signal reception is
put in the trunk.

■

If the tire pressure warning light frequently comes on after blinking
for approximately one minute

5-2. Steps to take in an emergency

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 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 the tire is flat, change to the spare tire and have the flat tire repaired
by the nearest Scion 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.

316

5-2. Steps to take in an emergency

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 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 pressure 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. 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 efficiency 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 maintenance, 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).

Your vehicle has also been equipped with a TPMS (tire pressure warning
system) malfunction indicator to indicate 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 detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indicator is illumi-
nated, the system may not be able to detect or signal low tire pressure
as intended.

5-2. Steps to take in an emergency

CAUTION

TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installation 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 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 system) to
continue to function properly.

NOTICE

■

To ensure the tire pressure warning system operates properly 

Do not install tires with different specifications or makers, as the tire
pressure warning system may not operate properly.

318

5-2. Steps to take in an emergency

If you have a flat tire

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 only in an emergency.

●

Make sure to check the tire pressure of the compact spare tire. 
(

P. 354)

■

When using the compact spare tire

As the compact spare tire is not equipped with the tire pressure warning
valve and transmitter, low inflation pressure of the 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.

■

If you have a flat rear tire

Install the compact spare tire on the front of the vehicle. Perform the fol-
lowing steps.

CAUTION

■

Using the tire jack

Improper use of the tire jack may lead to death or serious injuries due to
the vehicle suddenly falling off the jack.

●

Do not use the tire jack for any purpose other than replacing tires or
installing and removing tire chains.

●

Only use the tire jack that comes with this vehicle for replacing a flat
tire. 
Do not use it on other vehicles, and do not use other tire jacks for
replacing tires on this vehicle.

●

Always check that the tire jack is securely set to the jack point.

●

Do not put any part of your body under the vehicle supported by a jack.

●

Do not start or run the engine while your vehicle is supported by the
jack.

●

Do not raise the vehicle while someone is in it.

●

When raising the vehicle, do not put an object on or under the jack.

●

Do not raise the vehicle to a height greater than that required to
replace the tire.

●

Use a jack stand if it is necessary to get under the vehicle.

Take particular care when lowering the vehicle to ensure that no one
working on or near the vehicle may be injured.

326

5-2. Steps to take in an emergency

CAUTION

■

Replacing a flat tire

●

Do not touch the disc wheels or the area around the brakes immedi-
ately after the vehicle has been driven. 
After the vehicle has been driven the disc wheels and the area around
the brakes will be extremely hot. Touching these areas with hands, feet
or other body parts while changing a tire, etc. may result in burns.

●

Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the vehicle is moving.

●

Failure to follow these precautions could cause the wheel nuts to
loosen and the tire to fall off, resulting in death or serious injury.

• Have the wheel nuts tightened with a torque wrench to 89 ft•lbf (120

N•m, 12.2 kgf•m) as soon as possible after changing wheels.

• When installing a tire, only use wheel nuts that have been specifi-

cally designed for that wheel.

• If there are any cracks or deformations in the bolt screws, nut

threads or bolt holes of the wheel, have the vehicle inspected by
your Scion dealer.

• When installing the wheel nuts, be sure to install them with the

tapered ends facing inward. (
