2005 TOYOTA tC sensor

54
The SRS side airbag and curtain shield
airbag system is controlled by the airbag
sensor assembly. The airbag sensor as-
sembly consist of a safing sensor and
airbag sensor.
In a severe side impact, the side and
curtain shield airbag sensor and/or the
curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain
shield airbag inflators. At this time a
chemical reaction in the inflators quickly
fills the airbags with non–toxic gas to help
restrain the lateral motion of the occu-
pants.
When the airbags inflate, they produce a
fairly loud noise and release some smoke
and residue along with non–toxic gas. This
does not indicate a fire. This smoke may
remain inside the vehicle for some time,
and may cause some minor irritation to
the eyes, skin or breathing. Be sure to
wash off any residue as soon as possible
to prevent any potential skin irritation with
soap and water. If you can safely exit
from the vehicle, you should do so imme-
diately. Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is desi
gned to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swelling.
Front seats as well as part of the front
and rear pillars, and roof side rail may be
hot for several minutes, but the airbags
themselves will not be hot. The airbags
are designed to inflate only once.
CAUTION
SRS side airbags and curtain shield
airbags inflate with considerable
force. To reduce the possibility of
death or serious injury when they in-
flate, the driver, front passenger and
rear outside passengers must:
Wear their seat belts properly.
Remain properly seated with their
backs upright and against the seats
at all times.
13T031
Do not allow anyone to lean against
the door when the vehicle is in use,
since the side airbag and curtain
shield airbag could inflate with con-
siderable speed and force. Other-
wise, he/she may be killed or seri-
ously injured. Special care should
be taken especially when you have
a small child in the vehicle.

sors, side and curtain shield airbag sensor
assemblies, curtain shield airbag sensor
assemblies, driver ’s seat position sensor,
driver ’s seat belt buckle switch, seat belt
pretensioner assemblies, inflators, front
passenger ’s seat buckle switch, warning
light, interconnecting wiring and power
sources. (For details, see “Service remind-
er indicators and warning buzzers” on
page 93.)If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your

(a) Brake System Warning Light
This light comes on in the following cases
when the ignition key is in the “ON” posi-
tion.
When the parking brake is applied...
The light comes on for a few seconds
when the ignition key is turned to the
“ON” position even after the parking brake
is released.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
Have your vehicle checked at your
Scion dealer in the following cases:
The light does not come on even if the
parking brake is applied when the igni-
tion key is in the “ON” position.
The light does not come on even if the
ignition key is turned to the “ON” posi-
tion with the parking brake released.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If either of the following conditions
occurs, immediately stop your vehicle
at a safe place and contact your
Scion dealer.
The light does not turn off even
after the parking brake is released
while the engine is running.
In this case, the brakes may not
work properly and your stopping
distance will become longer. De-
press the brake pedal firmly and
bring the vehicle to an immediate
stop.
The brake system warning light re-
mains on together with the “ABS”
warning light.
In this case, not only the anti–lock
brake system will fail but also the
vehicle will become extremely un-
stable during braking.
(b) Driver’s Seat Belt Reminder Light and Buzzer
The light and buzzer acts as a reminder
to have the driver buckle up the seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes and
the buzzer sounds if the driver’s seat belt
is not fastened. Unless the driver fastens
the belt, the light continues flashing and
the buzzer sounds for about 6 seconds.
(c) Front Passenger ’s Seat Belt Reminder Light
The light acts as a reminder to have the
front passenger buckle up the seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes if a
passenger sits in the front passenger seat
and does not fasten the seat belt. Howev-
er, if a front passenger uses an additional
seat cushion, the light may not flash even
when the seat belt is not buckled up.
If luggage or other load is placed on the
front passenger seat, depending on its
weight and how it is placed on the seat,
built–in sensors in the seat cushion may
detect the pressure, causing the reminder
light to flash.

The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Scion dealer.
In this case, not only the anti–lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
(j) Open Door Warning Light
This light remains on until all the side
doors and back door are completely
closed. (k) SRS Warning Light
This light will come on when the igni-
tion key is turned to the “ON” position.
After about 6 seconds, the light will go
off. This means the systems of the air-
bags and seat belt pretensioners are
operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sensor
assemblies, curtain shield airbag sensor
assemblies, driver ’s seat position sensor,
driver’s seat belt buckle switch, front pas-
senger ’s seat belt buckle switch, seat belt
pretensioner assemblies, inflators, warning
light, interconnecting wiring and power
sources.
If any of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Scion dealer as
soon as possible to service the vehicle.
When the ignition key is turned to the
“ON” position, the light does not come
on, remains on for more than 6 sec-
onds.
The light comes on while driving.(l) Low Tire Pressure Warning Light
This light warns that the tire inflation pres-
sure of any one of the tires is critically
low. The light comes on when the ignition
key is turned to the “ON” position. It goes
off after a few seconds. This indicates
that the low tire pressure warning system
is functioning properly.
If the light comes on while driving, adjust
tire inflation pressure to the specified lev-
el. (See “Tires” on page 237.) After the
tire inflation pressure is adjusted, push the
tire pressure warning system reset switch
for a few seconds and make sure the
warning light goes off. If the light still
remains on or blinks once every second,
have the low tire pressure warning system
checked at your Scion dealer.
If the light blinks twice every second, the
low tire pressure warning system needs to
be initialized.
For details, see “Tire pressure warning
system” on page 107.

Anti–lock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at a moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
anti–lock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:
Driving on rough, gravel or
snow–covered roads.
Driving with tire chains installed.
Driving over the steps such as the
joints on the road.
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The anti–lock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels’ turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.
“ABS” warning light
This light comes on when the ignition
key is turned to the “ON” position. If
the anti–lock brake system works prop-
erly, the light turns off after a few sec-
onds. Thereafter, if the system malfunc-
tions, the light comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti–lock brake system does not operate,
but the brake system still operates con-
ventionally. When the “ABS” warning light is on (and
the brake system warning light is off), the
anti–lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.
If any of the following conditions oc-
curs, this indicates a malfunction some-
where in the components monitored by
the warning light system. Contact your
Scion dealer as soon as possible to
service the vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
