7. Curtain shield airbag sensors
8. Side and curtain shield airbag sensors
9. Airbag sensor assembly
The SRS side airbag and curtain shield
airbag system is controlled by the airbag
sensor assembly. The airbag sensor as-
sembly consists 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 air bags 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 happen 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 parts 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.
PS13547
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.
Sit up straight and well back in the
seat, distributing your weight evenly
in the seat. Do not apply excessive
weight to the outer side of the
seats with a side airbag, and to the
front pillar, rear pillar and roof side
rail with a curtain shield airbag.

This warning light system monitors the
airbag sensor assembly, front airbag
sensors, side and curtain shield airbag
sensors, curtain shield airbag sensors,
driver ’s seat position sensor, driver ’s seat
belt buckle switch, front passenger
occupant classification system, “AIRBAG
ON” indicator light, “AIRBAG OFF”
indicator light, front passenger ’s seat belt
buckle switch, seat belt pretensioner
assemblies, inflators, interconnecting
wiring and power sources. (For details,
see “Service reminder indicators and
warning buzzers” on page 114 in Section
1−6.)
If either of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion or remains on for more than 6
seconds or flashes.
The light comes on or starts flashing
while driving.
The SRS warning light and “AIRBAG OFF”
indicator light will come on if there is a
malfunction in the front passenger occu-
pant classification system.
PS13553
In the following cases, contact your Toyota
dealer as soon as possible:
Any of the SRS side airbags and cur-
tain shield airbags have been inflated.
The portion of the doors (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the SRS side airbags and curtain
shield airbags to inflate.
The surface of the seats with the side
airbag (shaded in the illustration) is
scratched, cracked, or otherwise dam-
aged.
The portion of the front pillars, rear
pillars or roof side rail garnishes (pad-
ding) containing the curtain shield air-
bags inside (shaded in the illustration)
is scratched, cracked, or otherwise
damaged.
NOTICE
Do not disconnect the battery cables
before contacting your Toyota dealer.

CAUTION
If the “ABS” warning light remains on
together with the brake system
warning light, immediately stop your
vehicle at a safe place and contact
your Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
(i) Open Door Warning Light
This light remains on until all the side
doors and back door are completely
closed.
(j) Electric Power Steering SystemWarning Light
The light comes on when the ignition key
is turned to the “ON” position. If the elec-
tric power steering system warning light
works properly, the light turns off after a
few seconds. If the system has malfunc-
tions, the light comes on again. If the following conditions occur, this
indicates a malfunction somewhere in
the parts monitored by the warning
light system. Contact your Toyota deal-
er 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 stays on while you are driv-
ing.
The warning light turning on while racing
the engine for a long time may not indi-
cate malfunction. To turn off the light, re-
start the engine and start driving.
CAUTION
If the electric power steering system
warning light comes on, take your ve-
hicle to Toyota dealer as soon as
possible. In this case, more effort is
required for the steering wheel to
turn than usual. Drive your vehicle
while firmly gripping the steering
wheel.
(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 system of the air-
bags and front seat belt pretensioners
are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors,
driver ’s seat position sensor, driver ’s seat
belt buckle switch, front passenger occu-
pant classification system, “AIRBAG ON”
indicator light, “AIRBAG OFF” indicator
light, front passenger ’s seat belt buckle
switch, seat belt pretensioner assemblies,
inflators, interconnecting wiring and power
sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota 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 for more than 6
seconds or flashes.
The light comes on or starts flashing
while driving.

When the antilock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
You may hear the anti−lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.
At the end of the anti −lock brake sys-
tem activation, the brake pedal may
move a little forward.
CAUTION
Do not overestimate the antilock
brake system: Although the antilock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti
lock brake system on.
If tire grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the antilock brake system does not
provide vehicle control.
Antilock 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
antilock 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 tire of specified size at
appropriate pressure: The antilock
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.
