nSRS warning light
This warning light system monitors the airbag sensor assembly, front impact
sensors, side impact sensors (front door), side impact sensors (front), side
impact sensors (rear), driver’s seat position sensor, driver’s seat belt buckle
switch, front passenger occupant classification system, “AIR BAG ON” indica-
tor light, “AIR BAG OFF” indicator light, front passenger’s seat belt buckle
switch, seat belt pretensioners (front), airbags, interconnecting wiring and
power sources. ( P. 3 4 )
n Front passenger detection sensor, seat belt reminder and warning
buzzer
l If luggage is placed on the front passenger seat, the front passenger detec-
tion sensor may cause the warning light to flash and the warning buzzer to
sound even if a passenger is not sitting in the seat.
l If a cushion is placed on the seat, the sensor may not detect a passenger,
and the warning light may not operate properly.
n If the malfunction indicator la mp comes on while driving
First check the following:
l Is the fuel tank empty?
If it is, fill the fuel tank immediately.
l Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after several driving trips.
If the light does not go off even after several trips, contact your Scion dealer
as soon as possible.

When the tire pressure warning light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured:
P. 272
If none of the tire s are punctured:
Turn the engine switch off then turn it to the “ON” position. Check if the
tire pressure warning light comes on or flashes.
If the tire pressure warning light comes on
After the temperature of the tires has lowered sufficiently, check the
inflation pressure of each tire and adjust them to the specified level.
If the warning light does not turn off even after several minutes have
elapsed, check that the inflation pressu re of each tire is at the specified
level and perform initialization. (P. 222)
If the warning light does not turn off even after several minutes have
elapsed, have the vehicle inspected by your Scion dealer immediately.
If the tire pressure warning light flashes for 1 minute then stays on
There may be a malfunction in the tire pressure warning system. Have
the vehicle inspected by your Scion dealer immediately.
nThe 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 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 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 inflation
pressure. The tire pressu re warning light will go off after a few minutes.
nConditions that the tire pressure warning system may not function
properly

nWarning buzzer
In some cases, the buzzer may not be heard because of noisy place or an
audio sound.
n Electric power steering system warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering system warning light may come on and the
warning buzzer may sound.

WARNING
nIf both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Scion
dealer. The vehicle will become extrem ely unstable during braking, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
n When the electric power steerin g system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavie r than usual when operating, hold
firmly and operate using more force than usual.
n
If the tire pressure warning light comes on
Handling method ( P. 266)
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.
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 probable 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.
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 system may not activate immediately.

WARNING
nMaintenance 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 dif-
ferent 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-ti re pressure warning system) that
illuminates a low tire pre ssure 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 effi ciency and tire tread life, and may
affect the vehicle’s hand ling and stopping ability.
Please note that the TPMS (tire pres sure warning system) is not a sub-
stitute for proper ti re maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached
the level to trigger illumina tion of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-
ing system) malfunction indicator to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) malfunc-
tion indicator is combined with the lo w tire pressure telltale (tire pressure
warning light). When the system dete cts a malfunction, the telltale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue up on subsequent vehicle start-ups
as long as the malfunction exists. When the malfunction indicator is illu-
minated, the system may not be able to detect or signal low tire pres-
sure 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 te lltale 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.
