Make sure the “AIR BAG ON” indi-
cator light is illuminated when us-
ing the seat belt extender for the
front passenger seat. If the “AIR
BAG OFF” indicator light is illumi-
nated, disconnect the extender
tongue from the seat belt buckle,
then reconnect the seat belt. Recon-
nect the seat belt extender after
making sure the “AIR BAG ON” in-
dicator light is illuminated. If you
use the seat belt extender while the
“AIR BAG OFF” indicator light is
illuminated, the front passenger air-
bag and side airbag on the front
passenger side may not activate
correctly, causing death or serious
injury in the event of collision.Be sure to wear the seat belt with-
out the seat belt extender if you
can fasten the seat belt without the
extender.
Do not use the seat belt extender
when installing a child restraint
system on the front or rear passen-
ger seat. If installing a child re-
straint system with the seat belt
extender connected to the seat belt,
the seat belt will not securely hold
the child restraint system, which
could cause death or serious injury
to the child or other passengers in
the event of collision.
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.

49
As far as the seat belt extender on the
front passenger side is concerned, do not
fail to disconnect the extender from the
seat belt after the above operation in or-
der to activate the front passenger airbag
correctly when getting into the vehicle
next time.
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 extend-
er 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
Scion dealer. Do not use the seat
until the seat belt is fixed, because
it cannot protect an adult occupant
or your child from death or serious
injury.
—Seat belt pretensioners
Both front seats are equipped with seat
belt pretensioners and are designed to
be activated in response to a severe
frontal 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.

50
The front passenger ’s seat belt pretension-
er will not activate if no passenger is
detected in the front passenger seat by
the front passenger occupant classification
system. However, the front passenger ’s
seat belt pretensioner may activate if lug-
gage is put on the seat, or the seat belt
is buckled up regardless of the presence
of an occupant in the seat. (As for the
front passenger occupant classification
system, see “—Front pass enger occupant
classification system” on page 68.)
The seat belt pretensioners and SRS air-
bags may not operate together in all colli-
sions.
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. “AIR BAG ON” and “AIR BAG OFF” indicator lights
4. Front passenger occupant classification system (ECU and sensors)
5. Seat belt pretensioner assemblies
6. Front passenger ’s seat belt buckle switch
7. Driver ’s seat belt buckle switch
8. 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.
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.

51
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.
If 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 your Scion dealer.
Do not modify, remove, strike or
open the seat belt pretensioner as-
semblies, airbag sensor or sur-
rounding area or wiring. Consult
your Scion dealer about any repair
and modification.
NOTICE
Do not perform any of the following
changes without consulting your
Scion dealer. Such changes can inter-
fere with proper operation of the 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 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 air-
bag sensor assembly, front airbag sensors,
side and curtain shield airbag sensors, cur-
tain shield airbag sensors, driver ’s seat
position sensor, driver ’s seat belt buckle
switch, front passenger occupant classifica-
tion system, “AIR BAG ON” indicator light,
“AIR BAG OFF” indicator light, front pas-
senger ’s seat belt buckle switch, seat belt
pretensioner assemblies, inflators, intercon-
necting wiring and power sources. (For de-
tails, see “Service reminder indicators and
warning buzzers” on page 113.)

52
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Scion dealer as soon as possible.
When the engine switch is turned to
the “ON” position, the light does not
come on or remains on for more than
about 6 seconds or flashes.
The light comes on or starts flashing
while driving.
If any seat belt does not retract or
cannot be pulled out due to a malfunc-
tion or activation of the relevant seat
belt pretensioner.
The seat belt pretensioner assembly or
surrounding area has been damaged.
In the following cases, contact your Scion
dealer as soon as possible:
The front of the vehicle (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the seat belt pretensioners to operate.
Either seat belt pretensioner assembly
or surrounding area is scratched,
cracked, or otherwise damaged.
The SRS (Supplemental Restraint Sys-
tem) front airbags are designed to pro-
vide further protection for the driver
and front passenger in addition to the
primary safety protection provided by
the seat belts.
Your vehicle is equipped with “ADVANCED
AIRBAGS” designed based on US motor
vehicle safety standards (FMVSS208). The
airbag system controls airbag deployment
power for the driver and front passenger.
The driver airbag system consists of the
driver seat’s position sensor, etc. The
front passenger ’s airbag system consists
of the front passenger occupant classifica-
tion sensor, etc.
SRS airbags—
—SRS driver airbag and front
passenger airbag

53
In response to a severe frontal impact,
the SRS front airbags work with the seat
belts to help reduce injury by inflating.
The SRS front airbags help reduce injuries
mainly to the driver ’s or front passenger ’s
head or chest caused by hitting the ve-
hicle interior.
The SRS front passenger airbag will not
activate if there is no passenger sitting in
the front passenger seat. However, the
front passenger airbag may deploy if lug-
gage is put in the seat, or the seat belt
is buckled up, regardless of the presence
of an occupant in the seat. (As for the
front passenger occupant classification
system, see “—Front passenger occupant
classification system” on page 68.)
Always wear your seat belt properly.CAUTION
The SRS front airbag system is de-
signed only as a supplement to the
primary protection of the driver and
front passenger seat belt systems.
The driver and front passenger 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
instructions and precautions con-
cerning the seat belt system, see
“Seat belts” on page 38.
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. Scion strong-
ly recommends that all infants and
children be placed in the rear seat
of the vehicle and properly re-
strained. The rear seat is the safest
for infants and children. For in-
structions concerning the installa-
tion of a child restraint system, see
“Child restraint” on page 73.

54
The SRS front airbags are designed to
deploy in severe (usually frontal) colli-
sions where the magnitude and duration
of the forward deceleration of the ve-
hicle exceed the designed threshold lev-
el.
The SRS front airbags will deploy in the
event of an impact that exceeds the set
threshold level (the level of force corre-
sponding to an approximately 20−30 km/h
[12 −18 mph] frontal collision with a fixed
wall that does not move or deform).
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 the vehicle is involved in an
underride co llision (e.g. a collision in
which the front of the vehicle “underrides”,
or goes under, the bed of a truck, etc.).
It is possible that in some collisions
where the forward deceleration of the ve-
hicle is very close to the designed thresh-
old level, the SRS front airbags and the
seat belt pretensioners may not activate
together.
Always wear your seat belts properly.
Collision from the side
Vehicle rollover
Collision from the rear
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. But, when
ever a
collision of any type causes sufficient
forward deceleration of the vehicle, de-
ployment of the SRS front airbags may
occur.
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 serious impact occurs to the under-
side of your vehicle. Some examples
are shown in the illustration.

55
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. “AIR BAG ON” and “AIR BAG OFF” indicator lights
5. Front passenger occupant classification system (ECU and sensors)
6. Front passenger ’s seat position sensor
7. Front passenger ’s seat belt buckle switch 8. Driver ’s seat belt buckle switch
9. Driver ’s seat position sensor
10. Airbag sensor assembly 11. Airbag module for driver (airbag and inflator) The airbag sensor assembly consists of a
safing sensor and airbag sensor.
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
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 imme-
diately.

56
Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is designed 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
The driver or front passenger who is
too close to the steering wheel or
dashboard during airbag deployment
can be killed or seriously injured.
Scion 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 must be prop-
erly restrained using the available
seat belts.
If the seat belt extender has been
connected to the driver ’s seat belt
buckle without wearing the seat belt
when using the extender in the
driver ’s seat, the SRS driver ’s air-
bag system will judge that the driv-
er wears the seat belt even if not
wearing it. In this case, the driver ’s
airbag may not activate correctly,
causing death or serious injury in
the event of a collision. Be sure to
wear the seat belt with the seat belt
extender. Otherwise, there will also
not be any effective protection in a
sudden stop or a collision provided
by the seat belt.
For instructions and precautions con-
cerning the seating position, see
“—Front seat precautions” on page
30.

57
Do not sit on the edge of the seat
or lean against the dashboard when
the vehicle is in use, since the
front passenger airbag could inflate
with considerable speed and force.
Anyone who is up against, or very
close to, an airbag when it inflates,
can be killed or seriously injured.
Sit up straight and well back in the
seat, and always use your seat belt
properly.Scion strongly recommends that all
infants and children be placed in
the rear seat of the vehicle and be
properly restrained.
Do not allow a child to stand up or
kneel on the front passenger seat,
since the front passenger airbag
could inflate with considerable
speed and force. Otherwise, the
child may be killed or seriously in-
jured.
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
restraint” on page 73.
