To release the belt, press the red
buckle release button and allow the belt
to retract.
If the belt does not retract smoothly, pull
it out and check for kinks or twists. Then
make sure it remains untwisted as it re-
tracts.
MS13017a
The driver and front passenger seat
belt pretensioners are designed to be
activated in response to a severe fron-
tal impact.
When the sensor detects a severe frontal
impact, the front seat belts are quickly
drawn back by the retractors so that the
belts snugly restrain the occupants.
The seat belt pretensioners are activated
even with no passenger in the front seat.
The seat belt pretensioners and SRS air-
bags may not operate together in all colli-
sions.

The seat belt pretensionersystem con-
sists mainly of the following components
and their locations are shown in the il-
lustration.
1. SRS warning light
2. Airbag sensor assembly
3. Seat belt pretensioner assemblies
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.
If the vehicle is involved in multiple colli-
sions, the pretensioner will activate for the
first collision, but will not activate for the
second or subsequent collisions.
CAUTION
Observe the following precautions to
reduce the risk of injury in the event
of sudden braking or an accident.
Failure to do so may cause death or
severe injury.
DIf the pretensioner has activated,
the SRS warning light will come on.
In that case, the seat belt cannot
be used again and must be re-
placed at any authorized Toyota
dealer or repairer, or another duly
qualified and equipped professional.
DDo not modify, remove, strike or
open the seat belt pretensioner as-
semblies, airbag sensor or sur-
rounding area or wiring. Consult
any authorized Toyota dealer or re-
pairer, or another duly qualified and
equipped professional about any re-
pair and modification.

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 seat belt pretensioners
are operating properly.
This warning light system monitors the
airbag sensor assembly, side airbag
sensors, side and curtain shield airbag
sensors, airbag manual on−off switch, seat
belt pretensioner assemblies, inflators,
warning light, interconnecting wiring and
power sources. (For details, see “Service
reminder indicators and warning buzzers”
on page 127 in Section 1−6.)
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional, as soon as possible.

The SRS front airbags may also deploy
if a serious impact occurs to the under-
side of your vehicle. Some examples
are shown in the illustration.
MS13033c
The SRS front airbag system consists
mainly of the following components, and
their locations are shown in the illustra-
tion.
1. Airbag manual on−off switch
2. SRS warning light
3. Airbag module for front passenger
(airbag and inflator)
4. Airbag sensor assembly
5. Airbag module for driver
(airbag and inflator)
The airbag sensor assembly consists of a
safing sensor and airbag sensor.
The airbag sensor constantly monitors 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 airbags 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.

DDo not put anything or any part of
your body on or in front of the
dashboard or steering wheel pad
that houses the front airbag sys-
tem. They might restrict inflation or
cause death or serious injury as
they are projected rearward by the
force of the deploying airbags. Like-
wise, the driver and front passenger
should not hold objects in their
arms or on their knees.
DDo 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, front passen-
ger airbag cover, front passenger
airbag or airbag sensor assembly.
Doing so may prevent the front air-
bag system from activating correct-
ly, cause sudden activation of the
system or disable the system,
which could result in death or seri-
ous injury.
Failure to follow these instructions
can result in death or serious injury.
Consult any authorized Toyota dealer
or repairer, or another duly qualified
and equipped professional, about any
repair and modification.

volved in a front or rear collision, if it
rolls over, or if it is involved in a low−

The SRS side airbag system is controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-

In a severe side impact, the side airbag
sensor triggers the side airbag inflators.
At this time a chemical reaction in the
inflators quickly fills the airbags with non−
