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 ªONº posi-
tion or remains on for more than 6
seconds.

The light comes on while driving.

If any seat belt does not retract or can
not be pulled out due to a malfunction
or activation of the relevant seat belt
pretensioner.

The seat belt pretensioner assembly or
surrounding area has been damaged.
In the following cases, contact your Toyota
dealer as soon as possible:

The front of the vehicle (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the seat belt pretensioners to operate.

Either seat belt pretensioner assembly
or surrounding area is scratched,
cracked, or otherwise damaged.
The SRS (Supplemental Restraint Sys-
tem) front airbags are designed to pro-
vide further protection for the driver
and front passenger in addition to the
primary safety protection provided by
the seat belts.
In response to a severe frontal impact,
the SRS front airbags work together with
the seat belts to help reduce injury by
inflating. The SRS front airbags help re-
duce injuries mainly to the driver's or front
passenger 's head or chest caused by hit-
ting the vehicle interior.

The SRS front airbag system consists
mainly of the following components, and
their locations are shown in the illustra-
tion.
1. Front airbag sensors
2. Front passenger occupant classification
indicator light
3. Airbag module for front passenger
(airbag and inflator)
4. Front passenger occupant classification
system (ECU and sensors)
5. Front passenger 's seat belt buckle
switch
6. Driver 's seat belt buckle switch
7. Driver 's seat position sensor8. Airbag sensor assembly
9. Airbag module for driver
(airbag and inflator)
10. SRS warning light
The airbag sensor assembly consists of a
safing sensor and airbag sensor.
The front airbag sensors constantly moni-
tor the forward deceleration of the vehicle.
If an impact results in a forward decelera-
tion beyond the designed threshold level,
the system triggers the airbag inflators. At
this time a chemical reaction in the infla-
tors very quickly fills the airbags with
non±toxic gas to help restrain the forward
motion of the occupants. The front airbags
then quickly deflate, so that there is no
obstruction of the driver 's vision should it
be necessary to continue driving.
When the airbags inflate, they produce a
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 designed to reduce serious inju-
ries, primarily to the head and chest, it
may also cause other, less severe injuries
to the face, chest, arms and hands. These
are usually in the nature of minor burns
or abrasions and swelling, but the force of
a deploying airbag can cause more seri-
ous injuries, especially if an occupant's
hands, arms, chest or head is in close
proximity to the airbag module at the time
of deployment. This is why it is important
for the occupant to: avoid placing any
object or part of the body between the
occupant and the airbag module; sit
straight and well back into the seat; wear
the available seat belt properly; and sit as
far as possible from the airbag module,
while still maintaining control of the ve-
hicle.
Parts of the airbag module (steering wheel
hub, airbag cover and inflator) may be hot
for several minutes after deployment, so
do not touch! The airbags inflate only
once. The windshield may be damaged by
absorbing some of the force of the inflat-
ing airbag.

The SRS side and curtain shield airbags
may deploy if a serious impact occurs
to the underside of your vehicle. Some
examples are shown in the illustration.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

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.
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 the occupants.

The front passenger occupant classifi-
cation indicator light indicates the ac-
tuation of the front passenger airbag,
side airbag on the front passenger seat
and front passenger 's seat belt preten-
sioner.
The indicator light will indicate ªOFFº
when the ignition switch is in the ªONº
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 ªOFFº indicator 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 rear 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 ªONº indicator is illu-
minated when an adult is seated in the
front passenger seat. If the ªOFFº indica-
tor is illuminated, ask the passenger to sit
up straight, well back in the seat, and
with the seat belt worn correctly. If the
ªOFFº indicator still remains illuminated,
either ask the passenger to move to the
rear seat, or if that is not possible, move
the front passenger seat fully rearward.
The front passenger occupant classifi-
cation indicator light will indicate ªONº
and ªOFFº when the ignition key is
turned to the ªONº position. After
about four seconds, it will go off. After
that, the front passenger occupant clas-
sification system operates and judges
whether to indicate ªONº or ªOFFº.
The SRS warning light will come on
and front passenger occupant classifi-
cation indicator light will indicate
ªOFFº if there is a malfunction in the
front passenger 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/her
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 ªChild restraintº on page 107 in this Section as for installing the
child restraint system.)

When it is unavoidable to install the
forward±facing child restraint sys-
tem on the front passenger seat,
install the child restraint system on
the front passenger seat in the
proper order. (As for the installation
order, see ªÐInstallation with seat
beltº on page 110 in this Section.)

Do not remove the seat.

Do not kick the front passenger
seat or subject it to severe impact.
Otherwise, the SRS warning light
may come on to indicate a malfunc-
tion of the detection system. In this
case, contact your Toyota dealer im-
mediately.
The front passenger occupant classifica-
tion indicator light may indicate ªONº (the
front passenger airbag and side airbag on
the front passenger seat may deploy)
even if observing the above cautions,
when a child sits in, or a forward±facing
child restraint system is installed on the
front passenger seat. Refer to all the cau-
tions in ªSRS driver airbag and front pas-
senger airbagº on page 86 and ªChild re-
straintº on page 107 in this Section.
The roll sensing of curtain shield air-
bags off switch (ªRSCA OFFº switch)
can turn off the curtain shield airbags
and seat belt pretensioners in a vehicle
rollover. This switch should only be
used if inflation is not desired (such as
extreme off±road driving).When you push the ªRSCA OFFº switch
for a few seconds with the ignition switch
on, the ªRSCA OFFº indicator 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 sens-
ing function is turned on. (For details
about the roll sensing function, see ªSRS
side airbags and curtain shield airbagsº on
page 93 in this Section.)
In a severe side impact, the curtain shield
airbags on impacted side will inflate even
if the roll sensing function is turned off.
(For details about the curtain shield air-
bags, see ªSRS side airbags and curtain
shield airbagsº on page 93 in this Sec-
tion.)
In a severe frontal impact, the seat belt
pretensioners will work even if the roll
sensing function is turned off. (For details
about the seat belt pretensioners, see
ªÐSeat belt pretensionersº on page 83 in
this Section.)
If the ignition switch is turned to ªACCº or
ªLOCKº with the roll sensing function off
and then the ignition switch is turned back
to ªONº, the roll sensing function will turn
back on automatically.
