belt is not fastened. Once the “ENGINE START STOP” switch is turned to
IGNITION ON mode, 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. 338)
• Flat tire (P. 346)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:

■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.

When trouble arises
339 5-2. Steps to take in an emergency
■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/cm2 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

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.
