ÐFront seat belt pretensioners
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
belt is quickly drawn back in by the re-
tractor so that the belt snugly restrains
the front seat occupants.
The seat belt pretensioners are activated
even with no passenger in the front seat.
Collisions occurring at certain speeds and
angles may cause the seat belt preten-
sioners and SRS airbags not to operate
all together.This indicator comes on when the igni-
tion key is turned to the ACCº or
ONº position. It goes off after about
6 seconds. This means the front seat
belt pretensioners are operating proper-
ly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, inflators, front
seat belt pretensioner assemblies, warning
light, interconnecting wiring and power
sources. (For details, see Service remind-
er indicators and warning buzzersº 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 any of
these may cause sudden operation of
the front seat belt pretensioners or
disable the system, which could re-
sult 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 followingchanges without consulting yourToyota dealer. Such changes caninterfere with proper operation of the
front seat belt pretensioners in somecases.

Installation of electronic devices
such as a mobile two- way radio,
cassette tape player or compactdisc 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 (bullbar, kangaroo bar, etc.), snowplow,
winches or any other equipment tothe front end

Repairs made on or near the frontfenders, 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 either
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 ACCº or
ONº position, or remains on.

The light comes on or flashes while
driving.

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

CAUTION
A driver or front passenger too close
to the steering wheel or dashboard
during airbag deployment can be
killed or seriously injured. Toyota
strongly recommends that:

The driver sit as far back as pos-
sible from the steering wheel while
still maintaining control of the ve-
hicle.

The front passenger sit as far back
as possible from the dashboard.

All vehicle occupants be properly
restrained using the available seat
belts.This indicator comes on when the igni-
tion key is turned to the ACCº or
ONº position. It goes off after about
6 seconds. This means the SRS airbags
are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, inflators, front
seat belt pretensioner assemblies, warning
light, interconnecting wiring and power
sources. (For details, see Service remain-
der indicators and warning buzzersº 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 airbags will deploy if the severi-
ty of the impact is above the designed
threshold level, comparable to an approxi-
mate 25 km/h (15 mph) collision in the
U.S.A. and 30 km/h (18 mph) collision in
Canada when impacting straight into a
fixed barrier that does not move or de-
form.
If the severity of the impact is below the
above threshold level, the SRS airbags
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 underridesº, 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.
Collision from the sideCollision from
the rear
Vehicle rollover
The SRS 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 low- speed frontal
collision.
Hitting a curb,
edge of pavement
or hard material Falling into or
jumping over a
deep hole
Landing hard or vehicle falling
The SRS airbags may deploy if a seri-
ous 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. Airbag module for driver (airbag and inflator)
3. Airbag module for front passenger (air- bag and inflator)
4. Airbag sensor assembly
5. SRS warning light
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.

Do not allow a child to stand up,
or to kneel on the front passenger
seat. The airbag inflates with con-
siderable speed and force; the child
may be killed or seriously injured.

Do not hold a child on your lap or
in your arms. Use a child restraint
system in the rear seat. For instruc-
tions concerning the installation of
a child restraint system, see Child
restraintº in this section.

Do not put objects or your pets on
or in front of the dashboard or
steering wheel pad that houses the
airbag system. They might restrict
inflation or cause death or serious
injury as they are projected rear-
ward by the force of deploying air-
bags. 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, front passen-
ger airbag cover, front passenger
airbag or airbag sensor assembly.
Doing any of these may cause sud-
den SRS 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.

SRS side airbags
The SRS (Supplemental Restraint Sys-
tem) side airbags are designed to pro-
vide further protection for occupants in
the following seats in addition to the
primary safety protection provided by
the seat belts.

Vehicles with bucket front seatsÐThe
SRS side airbags are designed to pro-
tect the driver and front passenger.

Vehicles with bench type front seatsÐ
The SRS side airbags are designed to
protect the driver and right- front pas-
senger. They are not designed to pro-
tect occupant in the center position.In response to a severe side impact, the
SRS side airbags work together with the
seat belts to help reduce injury by inflat-
ing. The SRS side airbags help to reduce
injuries mainly to the driver's or front pas-
senger 's chest. The SRS side airbag on
the passenger seat is activated even with
no passenger in the front seat.
Be sure to wear your seat belt properly.
CAUTION
SRS side airbags inflate with consid-
erable force. To avoid potential death
or serious injury when they inflate,
the driver and front passenger must:

Wear their seat belts properly

Remain properly seated with their
back upright and against the seat at
all times.
This indicator comes on when the igni-
tion key is turned to the ACCº or
ONº position. It goes off after about
6 seconds. This means the SRS side
airbags are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, inflators, front
seat belt pretensioner assemblies, warning
light, interconnecting wiring and power
sources. (For details, see Service remind-
er indicators and warning buzzersº in Sec-
tion 1- 5.)

The SRS side airbag system may not
activate 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 illustra-
tion.
The SRS side airbags are designed to
inflate when the passenger compartment
area suffers a severe impact from the
side.
For the safety of all occupants, always
wear your seat belts properly.
Collision from the frontCollision from the rear
Vehicle rollover
The SRS side 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 low- speed side
collision.The SRS side airbag system consists
mainly of the following components, and
their locations are shown in the illustra-
tion.1. SRS warning light
2. Airbag sensor assembly
3. Side airbag modules (airbag and inflat- or)
4. Side airbag sensors
The SRS side airbag system is controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.

In a severe side impact, the side airbag
sensor triggers the side airbag inflators.
Then a chemical reaction in the inflators
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
minor 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 may be hot for several min-
utes, but the airbags themselves will not
be hot. The airbags are designed to inflate
only once.CAUTION

The SRS side airbag system is de-
signed only as a supplement to the
primary protection of the driver
side and front 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 properly.
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 beltsº in this
section.

Improperly seated and/or restrained
infants and children can be killed
or seriously injured by the deploy-
ing airbags. An infant or child who
is too small to use a seat belt
should be properly secured using a
child restraint system. Toyota
strongly recommends that all in-
fants and children be placed in the
rear seat of the vehicle and proper-
ly restrained. The rear seat is the
safest for infants and children. For
instructions concerning the installa-
tion of a child restraint system, see
Child restraintº in this section.

Do not allow a child to lean his/her
head or any part of his/her body
against the front door or the area
of the seat from which the side air-
bag deploys even if he/she is
seated in the child restraint system.
It is dangerous if the side airbag
inflates, and the impact could cause
death or serious injury to the child.
For instructions concerning the
installation of a child restraint sys-
tem, see Child restraintº in this
section.
