To connect the extender to the seat
belt, insert the tab into the seat belt
buckle so that the “PRESS” signs on
the buckle release buttons of the ex-
tender and the seat belt are both facing
outward as shown.
You will hear a click when the tab locks
into the buckle.
When releasing the seat belt, press on
the buckle release button on the extender,
not on the seat belt. This helps prevent
damage to the vehicle interior and extend-
er itself.
When not in use, remove the extender
and store in the vehicle for future use.
CAUTION
After inserting the tab, make
sure the tab and buckle are
locked and that the lap and
shoulder portions of the belt and
the seat belt extender are not
twisted.
Do not insert coins, clips, etc. in
the buckle as this may prevent
you from properly latching the
tab and buckle.
If the seat belt does not function
normally, immediately contact
your Toyota dealer. Do not use
the seat until the seat belt is
fixed, because it cannot protect
an adult occupant or your child
from injury.
—Seat belt pretensioners
The seat belt pretensioners are de-
signed to be activated in response to
a severe frontal impact or a vehicle
rollover.
When the sensor detects a severe frontal
impact or a vehicle rollover, the front seat
belts are quickly drawn back by the re-
tractor 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.

Roll sensing of curtain shield airbags off
indicator light
The seat belt pretensioners will not oper-
ate in a vehicle rollover if the roll sensing
of curtain shield airbags off indicator light
is on. For details, see “Roll sensing of
curtain shield airbags off switch” on page
69.
CAUTION
Make sure the roll sensing of cur-
tain shield airbags off indicator
light is not on.
When the roll sensing of curtain
shield airbags off switch is turned
on (and the roll sensing of curtain
shield airbags off indicator light is
on), the seat belt pretensioners will
not operate in a vehicle rollover
and turning off the seat belt preten-
sioners can reduce the occupant
protection which your vehicle safety
systems can provide to you in cer-
tain accidents and increase the like-
lihood of death or serious injuries.
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. SRS warning light
3. Seat belt pretensioner assemblies
4. Airbag sensor assembly
The seat belt pretensioners are controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.

59
2004 L/C100 from Aug ’03 Prod. (OM60A04U)
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. Doing any
of these may prevent the seat belt
pretensioners from activating cor-
rectly, cause sudden operation of
the system or disable the system,
resulting in death or serious injury.
Do not use tires or wheels other
than the manufacturer ’s recom-
mended size. Such a use may cause
the curtain shield airbags and seat
belt pretensioners to inflate acci-
dentally, resulting in death or seri-
ous injury. For details, see “Check-
ing and replacing tires” on page
302.
Do not place luggage heavier than
specified on the roof luggage carri-
er. Such luggage may cause the
curtain shield airbags and seat belt
pretensioners to inflate accidentally,
resulting in death or serious injury.
For details, see “Roof luggage car-
rier” on page 200.
Do not modify or change the sus-
pension system. Such changes may
cause the curtain shield airbags to
inflate accidentally, resulting in
death or serious injury.
Failure to follow these instructions
can result in death or serious inju-
ries. Consult your Toyota dealer
about any repair and modification.
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 front end struc-
ture
 Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end

Collision from the rear
Collision from the side Vehicle rollover
The SRS front airbags are not generally
designed to inflate if the vehicle is in-
volved 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 surface Falling into or
jumping over a
deep hole
Landing hard or vehicle falling
The SRS front airbags may also deploy
if a severe impact occurs to the under-
side of your vehicle. Some examples
are shown in the illustration.The SRS front airbag system consists
mainly of the following components, and
their locations are shown in the illustra-
tion. 1. Front airbag sensors
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)
6. Driver ’s seat position sensor
7. Driver ’s seat belt buckle switch
The airbag sensor assembly consists of a
safing sensor and airbag sensor.

64
2004 L/C100 from Aug ’03 Prod. (OM60A04U)
The front airbag sensors constantly moni-
tor the forward deceleration of the vehicle.
If an impact results in a forward decelera-
tion beyond the designed threshold level,
the system triggers the airbag inflators. At
this time a chemical reaction in the inflat-
ors very quickly fills the airbags with non−
toxic gas to help restrain the forward mo-
tion of the occupants. The front airbags
then quickly deflate, so that there is no
obstruction of the driver ’s vision should it
be necessary to continue driving.
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 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 immediately. 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.CAUTION
A driver or front passenger who is
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
possible from the steering wheel
while still maintaining control of
the vehicle.
The front passenger sit as far
back as possible from the dash-
board.
All vehicle occupants be properly
restrained using the available
seat belts.

Do not hold a child on your lap
or in your arms. Use a child re-
straint system in the rear seat.
For instructions concerning the
installation of a child restraint
system, see “Child restraint” on
page 79.
Do 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
system. They might restrict infla-
tion or cause death or serious
injury as they are projected rear-
ward by the force of deploying
airbags. Likewise, the driver and
front passenger should not hold
objects in their arms or on their
knees.
Do not modify or remove any
wiring. Do not modify, remove,
strike or open any components
such as the steering wheel pad,
steering wheel, column cover,
dashboard near the front passen-
ger airbag, front passenger air-
bag or airbag sensor assembly.
Doing so may prevent the front
airbag system from activating
correctly, cause sudden activa-
tion of the system or disable the
system, resulting in death or se-
rious injury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Toyota dealer about any
repair and modification.

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

73
2004 L/C100 from Aug ’03 Prod. (OM60A04U)
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 inflators and/or the curtain
shield airbag inflators. Then a chemical
reaction in the inflators quickly fills the
airbags with non−toxic gas to help restrain
the lateral motion of front and second seat
occupants.
In a vehicle rollover, the airbag sensor
assembly triggers the curtain shield airbag
inflator. At this time, a chemical reaction
in the inflators quickly fills the airbags
with non −toxic gas to help restrain the
lateral motion of front and second seat
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 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 immediately.
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 pillar, front, center and rear gar-
nish and roof interior may be hot for sev-
eral minutes, but the airbags themselves
will not be hot. The airbags are designed
to inflate only once.CAUTION
The SRS side airbags and curtain
shield airbags inflate with consider-
able force. To reduce the possibility
of death or serious injury when they
inflate, the driver, front passenger
and second seat passengers must:
Wear their seat belts properly.
Remain properly seated with their
backs upright and against the seats
at all times.
Improper sitting and wearing of the
seat belts may not retain you inside
the vehicle.
