*1: 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” or
“START” position, the buzzer sounds for 5 seconds. If the vehicle reaches a
speed of 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 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 intermittently for
10 seconds after the vehicle reaches a speed of 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.
*3: Refer to the separate “Scheduled Maintenance Guide” or “Owner’s ManualSupplement” for the maintenance interval applicable to your vehicle.
■ SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag
sensors, side and curtain shield airbag sensors, curtain shield airbag sen-
sors, driver’s seat position sensor, driver’s seat belt buckle switch, front pas-
senger occupant classification system (ECU and sensors), “AIR BAG ON”
indicator light, “AIR BAG OFF” indicator light, front passenger’s seat belt
buckle switch, seat belt pretensioner assemblies, inflators, interconnecting
wiring and power sources. ( P. 69)

■
Front passenger detection sensor, 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 the 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.
■ If the malfunction indicator lamp comes on while driving
First check the following:
● Is the fuel tank empty?
If it is, fill the fuel tank immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The malfunction indicator lamp will go off after taking driving trips.
If the malfunction indicator lamp does not go off even after several trips, con-
tact your Scion dealer as soon as possible.
■
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level.
Pushing the tire pressure warning re set switch will not turn off the tire
pressure warning light.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such
as natural air leaks and tire inflat ion pressure changes caused by tem-
perature. 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 re paired tire and adjust the tire infla-
tion pressure. The tire pressure wa rning light will go off after a few min-
utes.

■If the tire pressure warning system is not functioning
The system will be disabled in the following conditions:
(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 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 becomes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies
are nearby.
●If a radio set at a similar frequency 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, particularly around the
wheels or wheel housings.
●If non-genuine Scion wheels are used. (Even if you use Scion
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 frequently comes on after blinking
for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1
minute when the engine switch is turned to the “ON” position, have it
checked by your Scion dealer.

■
Electric power steering system warning light (warning buzzer)
When the battery charge becomes insufficient of the voltage temporarily
drops, the electric power steering system warning light may come on and the
warning buzzer may sound.
CAUTION
■When the electric power steerin g system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.
■
If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause a 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 pr obable that you have a flat tire. Check the tires.
If a tire is flat, change it with th e 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 syste m may not activate immediately.

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 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).
