sole, steering column, steering
wheel or dashboard near the front
passenger airbag
The indicator comes on when the igni-
tion key is turned to the “ON” position.
It goes off after about 6 seconds. This
means the SRS front airbags are oper-
ating 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 occupant classification system and
indicator light, front passenger ’s seat belt
buckle switch, seat belt pretensioner as-
semblies, inflators, roll sensing of curtain
shield airbags off indicator light, intercon-
necting wiring and power sources. (For
details, see “Service reminder indicators
and warning buzzers” on page 132.)
If any 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 will come on and
front passenger occupant classification in-
dicator light will indicate “OFF” if there is
a malfunction in the front passenger occu-
pant classification system.

68
In the following cases, contact your Toyota
dealer as soon as possible:
The SRS front airbags have been in-
flated.
The front of the vehicle (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the SRS front airbags to inflate.
The pad section of the steering wheel
or dashboard (shaded in the illustra-
tion) is scratched, cracked, or other-
wise damaged.
NOTICE
Do not disconnect the battery cables
before contacting your Toyota dealer.

The SRS (Supplemental Restraint Sys-
tem) side airbags and curtain shield air-
bags are designed to provide further
protection for the driver, front passen-
ger and second seat passengers in
addition to the primary safety protec-
tion provided by the seat belts. In response to a severe side impact, the
SRS side airbags and curtain shield air-
bags on impacted side work with the seat
belts to help reduce injury by inflating.
The SRS side airbags help reduce injuries
mainly to the driver’s or front passenger’s
chest, and the SRS curtain shield airbags
help reduce injuries mainly to the driver ’s,
front passenger ’s or second seat passen-
ger’s head and can help the driver, front
passenger and second seat passengers to
retain inside the vehicle.
The SRS side airbag on the passenger
seat will not activate if there is no pas-
senger sitting in the front passenger seat.
However, the side airbag on the passen-
ger seat may deploy if luggage is put in
the seat, or the seat belt is buckled up
regardless of the presence of the occu-
pant in the seat. (As for the front passen-
ger occupant classification system, see
“Front passenger occupant classification
system” on page 79.)
—SRS side airbags and cur-
tain shield airbags

69
Roll sensing function:
In response to a vehicle rollover, the SRS
curtain shield airbags on both sides work
with the seat belts to help reduce injury
by inflating. The SRS curtain shield air-
bags help reduce injuries mainly to the
driver ’s, front passenger ’s or second seat
passenger ’s head and can help the driver,
front passenger and second seat passen-
gers to retain inside the vehicle.
The SRS curtain shield airbag on the pas-
senger side is activated even with no pas-
senger in the front seat or second seat.
The SRS curtain shield airbags may acti-
vate even when the side airbags are not
activated.
Always wear your seat belt properly.CAUTION
The SRS side airbag and curtain
shield airbag system is designed
only as a supplement to the prima-
ry protection of the driver, front
and second outboard seat passen-
ger seat belt systems. The front
and second seat occupants can be
killed or seriously injured by the
inflating airbags if they do not wear
the available seat belts properly.
During sudden braking just before
a collision, an unrestrained driver,
front passenger or second seat pas-
senger can move forward or side-
ways into direct contact with or
close proximity to the airbag which
may then deploy during the colli-
sion. To ensure maximum protection
in an accident, the driver and all
passengers in the vehicle must
wear their seat belts properly.
Wearing a seat belt properly during
an accident reduces the chances of
death or serious injury or being
thrown out of the vehicle. For
instructions and precautions con-
cerning the seat belt system, see
“Seat belts” on page 50.
Do not allow anyone to lean his/her
head or any part of his/her body
against the door or the area of the
seat, front pillar, rear pillar or roof
side rail from which the SRS side
airbag and curtain shield airbag
deploy even if he/she is a child
seated in the child restraint system.
It is dangerous if the SRS side air-
bag and curtain shield airbag in-
flate, and the impact of the deploy-
ing airbag could cause death or se-
rious injury to the occupant.
Improperly seated and/or restrained
infants and children can be killed
or seriously injured by the deploy-
ing airbags. An infant or child who
is too small to use a seat belt
should be properly secured using a
child restraint system. Toyota
strongly recommends that all in-
fants and children be placed in the
rear seats of the vehicle and prop-
erly restrained. The rear seats are
the safest for infants and children.
For instructions concerning the
installation of a child restraint sys-
tem, see “Child restraint” on page
83.

Roll sensing of curtain shield airbags
off switch
The roll sensing of curtain shield air-
bags off switch can turn off the curtain
shield airbags in a vehicle rollover. This
switch should only be used in a situa-
tion where the inflation is not desired
(such as extremeoff road driving).When you push the roll sensing of curtain
shield airbags off switch for a few sec-
onds with the ignition switch on, the roll
sensing of curtain shield airbags off indi-
cator light comes on and the roll sensing
function is turned off. When you push the
switch again, the indicator light goes off
and the roll sensing function is turned on.
In a severe side impact, the curtain shield
airbag on impacted side will inflate even
if the roll sensing function is turned off.
If the ignition switch is turned to “ACC” or
“LOCK” with the roll sensing function off
and then the ignition switch is turned back
to “ON”, the roll sensing function will be
back on automatically.
CAUTION
Make sure the roll sensing of cur-
tain shield airbags off indicator
light is not on.
When the roll sensing of curtain
shield airbags off switch is turned
on (and the roll sensing of curtain
shield airbags off indicator light is
on), the curtain shield airbags will
not inflate in a vehicle rollover and
turning off the curtain shield air-
bags can reduce the occupant
protection which your vehicle safety
systems can provide to you in cer-
tain accidents and increase the like-
lihood of death or serious injuries.

71
The SRS side airbag and curtain shield
airbag system may not activate if the
vehicle is subjected to a collision from
the side at certain angles, or a collision
to the side of the vehicle body other
than the passenger compartment as
shown in the illustration.
The SRS side airbags are designed to
inflate when the passenger compartment
area suffers a severe impact from the
side.
The curtain shield airbags are designed to
inflate when the passenger compartment
area suffers a severe impact from the
side or vehicle rollover.
Always wear your seat belts properly.
Collision from the rear
Collision from the front Vehicle rollover
The SRS side airbags are not generally
designed to inflate if the vehicle is in-
volved in a front or rear collision, if it
rolls over, or if it is involved in a low
speed side collision.
The angle of
vehicle tip−up
is marginal Skidding vehicle
hitting a curb
stone
The curtain shield airbags may inflate
if the angle of vehicle tipup is margin-
al or if the skidding vehicle’s tires hit
a curb stone laterally as shown in the
illustration.

72
Collision from
the frontCollision from
the rear
Pitch end over end
The curtain shield airbags are not gen-
erally designed to inflate if the vehicle
is involved in a front or rear collision,
if it pitches end over end or if it is
involved in a lowspeed side collision.
Hitting a curb, edge of
pavement or hard sur-
face Falling into or jump-
ing over a deep hole
Landing hard or vehicle falling
The SRS side airbags and curtain shield
airbags may deploy if a severe impact
occurs to the underside of your vehicle.
Some examples are shown in the il-
lustration.
13c538d
The SRS side airbag and curtain shield
airbag system consists mainly of the fol-
lowing components, and their locations are
shown in the illustration.
1. SRS warning light
2. Front passenger occupant classification indicator light
3. Curtain shield airbag modules (airbag and inflator)
4. Front passenger occupant classification system (ECU and sensors)
5. Front passenger ’s seat belt buckle switch
6. Side airbag modules (airbag and inflator)

73
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.
In a vehicle rollover, the airbag sensor
assembly triggers the curtain shield airbag
inflator. At this time, a chemical reaction
in the inflators quickly fills the airbags
with non −toxic gas to help restrain the
lateral motion of front and second seat
occupants. 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 parts of the front
and rear pillar, front, center and rear gar-
nish and roof interior may be hot for sev-
eral 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
second seat passengers must:
Wear their seat belts properly.
Remain properly seated with their
backs upright and against the seats
at all times.

7413c562
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 and rear pillar, front, center
and rear garnish and roof interior
with the curtain shield airbag.
Improper sitting and wearing of the
seat belts may not retain you inside
the vehicle.
Make sure the roll sensing of cur-
tain shield airbags off indicator is
not on. The curtain shield airbags
will not inflate in a vehicle rollover
if this indicator light is on and you
may be killed or seriously injured.
