If the light stays on, it indicates that the
SRS driver and front passenger airbag
system and/or front passenger occupant
classification system and “AIRBAG ON”
and “AIRBAG OFF” indicator lights have a
problem. If the light flashes, the SRS side
airbag system and/or curtain shield airbag
system have a problem.
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.
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 front passenger airbag cover
(shaded in the illustration) is scratched,
cracked, or otherwise damaged.
NOTICE
Do not disconnect the battery cables
before contacting your Toyota dealer.

Collision from the rear
Collision from the front Vehicle rollover
The SRS side airbags and curtain shield
airbags are not generally designed to
inflate if the vehicle is involved in a
front or rear collision, if it rolls over,
or if it is involved in a lowspeed side
collision.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. “AIRBAG ON” and “AIRBAG OFF” indi- cator lights
3. Curtain shield airbag modules (airbag and inflator)
4. Front passenger occupant classification system (ECU and sensors)
5. Side airbag modules (airbag and inflator)
6. Curtain shield airbag sensors
7. Side and curtain shield airbag sensors 8. Front passenger ’s seat belt buckle
switch
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 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.

NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
SRS side airbag and curtain shield
airbag system in some cases.
Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player

sole or front seat
This 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 side airbags and curtain
shield airbags are operating properly. This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er ’s seat position sensor, driver ’s seat belt
buckle switch, front passenger occupant
classification system, “AIRBAG ON” indi-
cator light, “AIRBAG OFF” indicator light,
front passenger ’s seat belt buckle switch,
seat belt pretensioner assemblies, inflat-
ors, warning light, interconnecting wiring
and power sources. (For details, see “Ser-
vice reminder indicators and warning buzz-
ers” on page 129 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.
When the ignition key is turned to the
“ON” position, the light does not come
on, remains on for more than 6 sec-
onds or flashes.
The light comes on or starts flashing
while driving.

Your vehicle is equipped with a front
passenger occupant classification sys-
tem. This system detects the conditions
1—4 in the table on page 83 and based
on these conditions activates or deacti-
vates front passenger airbags. The sys-
tem monitors the weight and load on
the front passenger seat, and the seat
belt buckle switch to determine condi-
tions 1—4. In order for the system to
detect the conditions correctly, do not
do any of the following.
Put a heavy load in the front passen-
ger seat.
Attach a seatback table to the front
passenger seat seatback.
Put weight on the front passenger by
putting your hands or feet on the front
passenger seat seatback from the rear
passenger seat.
The “AIRBAG ON” and “AIRBAG OFF”
indicator lights indicate the actuation of
the front passenger airbag, side airbag
on the front passenger seat and front
passenger ’s seat belt pretensioner.
The “AIRBAG OFF” indicator light will be
illuminated when the ignition switch is in
the “ON” position with the condition 2 in
the table shown below. If the front passenger occupant classifica-
tion system determines that a person of
adult size sits in the front passenger seat
but the “AIRBAG OFF” indicator light is
illuminated, one of the following is likely
to have occurred:
A rear passenger lifts the front passen-
ger seat cushion with their legs.
Objects are placed under the front pas-
senger seat.
The front passenger seatback is in
contact with the second seat.
To ensure the system correctly detects an
adult sitting in the front passenger seat,
make sure the above do not occur.
Make sure that the “AIRBAG ON” indicator
light is illuminated when an adult is
seated in the front passenger seat. If the
“AIRBAG OFF” indicator light is illumina-
ted, ask the passenger to sit up straight,
well back in the seat, and with the seat
belt worn correctly. If the “AIRBAG OFF”
indicator light still remains illuminated, ei-
ther ask the passenger to move to the
rear seat, or if that is not possible, move
the front passenger seat fully rearward.

The “AIRBAG ON” and “AIRBAG OFF”
indicator lights will be illuminated ini-
tially when the ignition key is turned to
the “ON” position. After about 4 sec-
onds, they will go off. After that, the
front passenger occupant classification
system operates and judges which indi-
cator light be illuminated.
The SRS warning light and “AIRBAG
OFF” indicator light will come on if
there is a malfunction in the front pas-
senger occupant classification system.

∗1: The system judges a person of adult size as an adult. When a smaller adult sits in the front passenger seat, the system may
recognize him/her as a child depending on his/her physique and posture.
∗2: When a larger child who has outgrown a child restraint system sits in the front passenger seat, the system may recognize him/h er
as an adult depending on his/her physique or posture.
∗ 3: Never install a rear −facing child restraint system on the front passenger seat. A forward −facing child restraint system should only be
installed on the front passenger seat when it is unavoidable. (See “Child restraint” on page 85 in this Section as for installi ng the
child restraint system.)

CAUTION
To avoid potential death or serious
injury when the front passenger occu-
pant classification system does not
detect the conditions correctly, ob-
serve the following.
Do not recline the front passenger
seat seatback so that it interferes
with a second seat as it may cause
the “AIRBAG OFF” indicator light
be illuminated. If the seatback inter-
feres with the second seat, return
the seatback to a position where it
does not interfere with the second
seat.
Avoid reclining the front passenger
seat seatback too much while the
vehicle is moving, as it lessens the
effectiveness of the seat belt.
Make sure the “AIRBAG ON” indica-
tor light is illuminated when using
the seat belt extender for the front
passenger seat. If the “AIRBAG
OFF” indicator light is illuminated,
disconnect the extender tongue
from the seat belt buckle, then re-
connect the seat belt. Reconnect
the seat belt extender after making
sure the “AIRBAG ON” indicator
light is illuminated. If you use the
seat belt extender while the “AIR-
BAG OFF” indicator light is illumi-
nated, the front passenger airbag
and side airbag on the front pas-
senger side may not activate cor-
rectly, which could cause death or
serious injury in the event of colli-
sion.If an adult sits in the front
passenger seat, the “AIRBAG ON”
indicator light should be illumi-
nated. If the “AIRBAG OFF”
indicator light is illuminated, ask
the passenger to sit up straight,
well back in the seat, feet on the
floor, and with the seat belt worn
correctly. If the “AIRBAG OFF”
indicator light still remains illumi-
nated, either ask the passenger to
move to the rear seat, or if that is
not possible, move the front
passenger seat fully rearward.
Wear the seat belt properly.
Make sure the front passenger ’s
seat belt tab has not been left in-
serted into the buckle before some-
one sits in the front passenger
seat.
Do not put a heavy load in the
front passenger seatback pocket or
attach a seatback table to the front
passenger seat seatback.
Do not let a rear passenger lift the
front passenger seat with their feet
or press on the seatback with their
legs.
