The driver and front passenger ’s seat
belt pretensioners are designed to be
activated in response to a severe fron-
tal impact.
When the airbag sensor detects the shock
of a severe frontal impact, the front seat
belts are quickly drawn back in by the
retractors so that the belts snugly restrain
the front seat occupants.
The front seat belt pretensioners are acti-
vated even with no passenger in the 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 front seat belt pretensioners
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 seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources. (For
details, see “Service reminder indicators
and warning buzzers” on page 99 in Sec-
tion 1−5.)The front seat belt pretensioner system
mainly consists of the following compo-
nents and their locations are shown in the
illustration.
1. Front airbag sensors
2. SRS warning light
3. Front seat belt pretensioner assemblies
4. Airbag sensor assembly
The front seat belt pretensioners are con-
trolled by the airbag sensor assembly. The
airbag sensor assembly consists of a saf-
ing sensor and airbag sensor.

When the front seat belt pretensioners are
activated, an operating noise may be
heard and a small amount of smoke−like
gas may be released. This gas is harm-
less and does not indicate that a fire is
occurring.
Once the front seat belt pretensioners
have been activated, the seat belt retrac-
tors remain locked.
CAUTION
Do not modify, remove, strike or open
the front seat belt pretensioner as-
semblies, airbag sensor or surround-
ing area or wiring. Doing so may
cause sudden operation of the front
seat belt pretensioners or disable the
system, which could result in death
or serious injury.
Failure to follow these instructions
can result in death or serious inju-
ries.
NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
front seat belt pretensioners in some
cases.
 Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player
 Repairs on or near the front seat
belt retractor assemblies
 Modification of the suspension sys-
tem
 Modification of the front end struc-
ture
 Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end
 Repairs made on or near the front
fenders, front end structure or con-
sole
This front seat belt pretensioner system
has a service reminder indicator to inform
the driver of operating problems. If any of
the following conditions occurs, this
indicates a malfunction of the airbags or
pretensioners. 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 the light remains on.
The light comes on or flashes while
driving.

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 front airbags are oper-
ating 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 seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources. (For
details, see “Service reminder indicators
and warning buzzers” on page 99 in Sec-
tion 1−5.)The SRS front airbag system is de-
signed to activate in response to a se-
vere frontal impact within the shaded
area between the arrows in the illustra-
tion.
The SRS front airbags will deploy if the
severity of the impact is above the de-
signed threshold level, comparable to an
approximate 25 km/h (15 mph) collision
when impacting straight into a fixed barrier
that does not move or deform.
If the severity of the impact is below the
above threshold level, the SRS front air-
bags may not deploy. However, this threshold velocity will be
considerably higher if the vehicle strikes
an object, such as a parked vehicle or
sign pole, which can move or deform on
impact, or if it is involved in an underride
collision (e.g. a collision in which the nose
of the vehicle “underrides”, or goes under,
the bed of a truck, etc.).
It is possible that in some collisions at the
lower zone of airbag sensor detection and
activation the SRS airbags and seat belt
pretensioners will not operate all together.
For the safety of all occupants, always
wear your seat belts properly.

The SRS front airbags are not designed
to inflate if the vehicle is involved in a
side or rear collision, if it rolls over, or
if it is involved in a lowspeed frontal
collision.

The front SRS airbags may deploy if a
serious impact occurs to the underside
of your vehicle. Some examples are
shown in the illustration.The SRS airbag system consists mainly of
the following components, and their loca-
tions are shown in the illustration. 1. Front airbag sensors
2. SRS warning light
3. Airbag module for front passenger (airbag and inflator)
4. Driver ’s seat belt buckle switch
5. Driver ’s seat position sensor
6. Airbag sensor assembly
7. Airbag module for driver (airbag and inflator)
The airbag sensor assembly consists of a
safing sensor and airbag sensor.

In a severe frontal impact, the sensors
detect deceleration and the system trig-
gers the airbag inflators. Then a chemical
reaction in the inflators quickly fills the
airbags with non−toxic gas to help restrain
the forward motion of the 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 gas is nor-
mally harmless; however, for those who
have delicate skin, it may cause a minor
skin irritation. Be sure to wash off any
residue as soon as possible to prevent
any potential skin irritation.
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.
Parts of the airbag module (steering wheel
hub, dashboard) may be hot for several
minutes, but the airbags themselves will
not be hot. The airbags are designed to
inflate only once. A crash severe enough to inflate the air-
bags may break the windshield as the
vehicle buckles. In vehicles with a pas-
senger airbag the windshield may also be
damaged by absorbing some of the force
of the inflating airbag.CAUTION
The SRS airbag system is designed
only as a supplement to the prima-
ry protection of the driver side and
front passenger side seat belt sys-
tems. The front 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
or front passenger can move for-
ward 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. Wear-
ing a seat belt properly during an
accident reduces the chances of
death or serious injury or being
thrown out of the vehicle. For in-
structions and precautions concern-
ing the seat belt system, see “Seat
belts” on page 41 in this section.

Do not put objects or your pets on
or in front of the dashboard or
steering wheel pad that houses the
front airbag system. They might re-
strict inflation or cause death or
serious injury as they are projected
rearward by the force of deploying
airbags. Likewise, the driver and
front passenger should not hold
things in their arms or on their
knees.
Do not modify or remove any wir-
ing. Do not modify, remove, strike
or open any components such as
the steering wheel pad, steering
wheel, column cover or front pas-
senger airbag cover, front passen-
ger airbag, airbag sensor assembly.
Doing so may cause sudden SRS
front airbag inflation or disable the
system, which could result in death
or serious injury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Toyota dealer about any
repairs and modifications.NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
SRS front airbag system in some
cases.

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 seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources. (For
details, see “Service reminder indicators
and warning buzzers” on page 99 in Sec-
tion 1−5.)The SRS side airbag and curtain shield
airbag system may not inflate 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 and curtain shield
airbags are designed to inflate when the
passenger compartment area suffers a se-
vere impact from the side.
For the safety of all occupants, always
wear your seat belts properly.
Collision from the rear
Collision from the front Vehicle rollover
The SRS side airbags and curtain shield
airbags are not 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. Curtain shield airbag modules (airbag and inflator)
3. Side airbag modules (airbag and inflator)
4. Curtain shield airbag sensors
5. Side and curtain shield airbag sensors
6. 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 and curtain shield airbag inflat-
ors and/or the curtain shield airbag inflat-
ors. Then a chemical reaction in the inflat-
ors quickly fills the airbags with non
−toxic
gas to help restrain the lateral motion of
the 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 gas is nor-
mally harmless; however, for those who
have delicate skin, it may cause a minor
skin irritation. Be sure to wash off any
residue as soon as possible to prevent
any potential skin irritation.
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 pillars, and roof side may be hot
for several minutes, but the airbags them-
selves will not be hot. The airbags are
designed to inflate only once.
CAUTION
The SRS side airbag and curtain
shield airbag system is designed
only as a supplement to the prima-
ry protection of the driver side, and
front and rear outside passenger
side seat belt systems. To ensure
maximum protection in an accident,
the driver and all passengers in the
vehicle must wear their seat belts.
Wearing a seat belt during an acci-
dent reduces the chances of death
or serious injury or being thrown
out of the vehicle. For instructions
and precautions concerning the seat
belt system, see “Seat belts” on
page 41 in this section.
