SEATS, SEAT BELTS, STEERING WHEEL AND MIRRORS35
The driver ’s seat belt pretensioner is
designed to be activated in response to
a severe frontal impact.
When the airbag sensor detects the shock
of a severe frontal impact, the driver ’s
seat belt is quickly drawn back in by the
retractor so that the belt snugly restrains
the driver.
Collisionsoccurring at certain speeds and
angles may cause the seat belt preten-
sioner and SRS airbag not to operate all
together.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 driver ’s seat belt pre-
tensioner is operating properly.
This warning light system monitors the
airbag sensor assembly, airbag sensor,
driver ’s seat belt pretensioner assembly,
inflator, interconnecting wiring and power
sources. (For details, see “Service remind-
er indicators and warning buzzer” on page
73 in Section 1−5.)

pretensioner

36SEATS, SEAT BELTS, STEERING WHEEL AND MIRRORS
The driver ’s seat belt pretensionersystem
mainly consists of the following compo-
nents and their locations are shown in the
illustration.
1. SRS warning light
2. Airbag sensor
3. Driver ’s seat belt pretensioner assem-
bly
4. Airbag sensor assembly
The driver ’s seat belt pretensioner is con-
trolled by the airbag sensor assembly. The
airbag sensor assembly consists of a saf-
ing sensor and airbag sensor.
When the driver ’s seat belt pretensioner is
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 driver ’s seat belt pretensioner
has been activated, the seat belt retractor
remains 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
serious 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.

In the following cases, contact any autho-
rized Toyota dealer or repairer, or another
duly qualified and equipped professional,
as soon as possible:
DThe front of the vehicle (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the driver ’s seat belt pretensioner to
operate.
DThe driver ’s seat belt pretensioner as-
sembly or surrounding area is
scratched, cracked, or otherwise dama-
ged.
The SRS (Supplemental Restraint Sys-
tem) airbag is designed to provide fur-
ther protection for the driver in addition
to the primary safety protection pro-
vided by the seat belt.
In response to a severe frontal impact,
the SRS airbag works together with the
seat belt to help reduce injury by inflating.
The SRS airbag helps to reduce injuries
mainly to the driver ’s head or chest
caused by directly hitting the steering
wheel.
Be sure to wear your seat belt properly.
CAUTION
The driver who is too close to the
steering wheel during airbag deploy-
ment can be killed or seriously in-
jured. Toyota strongly recommends
that:
DThe driver sit as far back as pos-
sible from the steering wheel while
still maintaining control of the ve-
hicle.
DAll vehicle occupants must be prop-
erly restrained using the available
seat belts.

SRS driver airbag

SEATS, SEAT BELTS, STEERING WHEEL AND MIRRORS39
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 airbag is operating
properly.
This warning light system monitors the
airbag sensor assembly, airbag sensor,
driver ’s seat belt pretensioner assembly,
inflator, interconnecting wiring and power
sources. (For details, see “Service
reminder indicators and warning buzzer”
on page 73 in Section 1−5.)The SRS airbag system is designed to
activate in response to a severe frontal
impact within the shaded area between
the arrows in the illustration.
The SRS airbag will deploy in the event
of an impact that exceeds the set thresh-
old level (the level of force corresponding
to an approximately 20−30 km/h [12−18
mph] frontal collision with a fixed wall that
does not move or deform).
If the severity of the impact is below the
above threshold level, the SRS airbag
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 airbag and seat belt
pretensioner will not operate all together.
For the safety of all occupants, always
wear your seat belts properly.

The SRS airbag system consists mainly of
the following components, and their loca-
tions are shown in the illustration.
1. SRS warning light
2. Airbag module for driver
(airbag and inflator)
3. Airbag sensor
4. Airbag sensor assembly
The airbag sensor assembly consists of a
safing sensor and airbag sensor.
In a severe frontal impact, the sensor de-
tects deceleration and the system triggers
the airbag inflator. At this time a chemical
reaction in the inflator quickly fills the air-
bag with non−toxic gas to help restrain
the forward motion of the driver.
When the airbag inflates, it produces a
fairly loud noise and releases some
smoke and residue along with non−toxic
gas. This does not indicate a fire. This
gas is normally 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 airbag happens in a
fraction of a second, so the airbag must
inflate with considerable force. While the
system is designed to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swelling.The steering wheel hub may be hot for
several minutes, but the airbag itself will
not be hot. The airbag is designed to
inflate only once.
CAUTION
The SRS airbag system is designed
only as a supplement to the primary
protection of the driver side seat belt
system. The driver can be killed or
seriously injured by the inflating air-
bag if he/she does not wear the avail-
able seat belt properly. During sudden
braking just before a collision, an un-
restrained driver can move forward
into direct contact with or close prox-
imity to the airbag which may then
deploy during the collision. To ensure
maximum protection in an accident,
the driver and all passengers in the
vehicle must wear their seat belts
properly. Wearing a seat belt properly
during an accident reduces the
chances of death or serious injury or
being thrown out of the vehicle. For
instructions and precautions concern-
ing the seat belt system, see “Seat
belts” on page 28 in this Section.

CAUTION
DDo not put objects or your pets on
or in front of the steering wheel
pad. They might restrict inflation or
cause death or serious injury as
they are projected rearward by the
force of a deploying airbag. Like-
wise, the driver should not hold ob-
jects in his/her arms or on his/her
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 or airbag sen-
sor assembly. Doing so may cause
sudden SRS airbag inflation or dis-
able the system, which could result
in death or serious 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
repairs and modifications.
