The seat belt pretensioners will not oper-
ate in a vehicle rollover if the “RSCA
OFF” indicator light is on. For details, see
“—Roll sensing of curtain shield airbags
off switch” on page 114 in this Section.
XS13139
The seat belt pretensioner system con-
sists mainly of the following components
and their locations are shown in the il-
lustration.
1. Front airbag sensors
2. Passenger airbag on −off indicator light
3. Front passenger occupant classification ECU
4. Load sensor
5. Seat belt pretensioner assemblies
6. Front passenger ’s seat belt buckle switch
7. Airbag sensor assembly 8. SRS warning light
The seat belt pretensioners are controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.
When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of non −toxic gas may
be released. This does not indicate that
a fire is occurring. This gas is normally
harmless.
Once the seat belt pretensioners have
been activated, the seat belt retractors
remain locked.
CAUTION
Do not modify, remove, strike or
open the seat belt pretensioner as-
semblies, airbag sensor or sur-
rounding area or wiring. Failure to
follow these instructions may pre-
vent the seat belt pretensioners
from activating correctly, cause sud-
den operation of the system or dis-
able the system, which could result
in death or serious injury. Consult
your Toyota dealer about any repair
and modification.

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
∗, passenger
airbag off switch, passenger airbag on −off
indicator light, seat belt pretensioner
assemblies, inflators, “RSCA OFF”
indicator light, interconnecting wiring and
power sources. (For details, see “Service
reminder indicators and warning buzzers”
on page 197 in Section 1 −6.)
∗: The front passenger occupant classifica-
tion system includes the front passenger
occupant classification ECU, load sensor,
front passenger ’s seat belt buckle switch.
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
engine switch is turned to the “ON”
position 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.
XS13121
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.

9. Driver ’s seat position sensor
10. Airbag sensor assembly
11. Airbag module for driver (airbag and inflator)
12. SRS warning light
The airbag sensor assembly consists of a
safing sensor and airbag sensor.
The airbag sensors constantly monitor the
forward deceleration of the vehicle. If an
impact results in a forward deceleration
beyond the designed threshold level, the
system triggers the airbag inflators. At this
time a chemical reaction in the inflators
very quickly fills the air bags with non−tox-
ic gas to help restrain the forward motion
of the occupants. The front airbags then
quickly deflate, so that there is no ob-
struction 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 desi
gned 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.

This indicator comes on when the en-
gine switch is turned to the “ON” posi-
tion. It goes off after about 6 seconds.
This means the SRS airbags are operat-
ing properly. This warning light system monitors the
airbag sensor assembly, front airbag
sensors, side and curtain shield airbag
sensors, driver ’s seat position sensor,
driver ’s seat belt buckle switch, front
passenger occupant classification system
∗,
passenger airbag off switch, passenger
airbag on −off indicator light, seat belt
pretensioner assemblies, inflators, “RSCA
OFF” indicator light, interconnecting wiring
and power sources. (For details, see
“Service reminder indicators and warning
buzzers” on page 197 in Section 1 −6.)
∗: The front passenger occupant classifica-
tion system includes the front passenger
occupant classification ECU, load sensor
and front passenger ’s seat belt buckle
switch.
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
engine switch is turned to the “ON”
position or remains on for more than
6 seconds.
The light comes on while driving. The SRS warning light will come on and
passenger airbag on
−off indicator light will
indicate “OFF” if there is a malfunction in
the front passenger occupant classification
system.

The SRS warning light and the passen-
ger airbag onoff indicator light will in-
dicate “OFF” if there is a malfunction
in the passenger airbag off switch.
CAUTION
Do not turn off the passenger air-
bag off switch except when a mem-
ber of a passenger risk group iden-
tified in TABLE 1 is occupying the
right front passenger seating posi-
tion.
When the passenger airbag off
switch is turned off, the front pas-
senger airbag will not inflate in a
collision and turning off the front
passenger airbag can reduce the
occupant protection which your ve-
hicle safety systems can provide to
you in certain accidents and in-
crease the likelihood of death or
serious personal injuries.
For details, see “—SRS driver airbag
and front passenger airbag” on page
77 in this Section.

The SRS (Supplemental Restraint Sys-
tem) front airbags are designed to pro-
vide further protection for the driver
and right front passenger in addition to
the primary safety protection provided
by the seat belts.
