Before driving
The SRS airbag can function only when the engine switch is in the “ON”
position.
The Scion advanced frontal airbag system is designed to determine the acti-
vation or deactivation condition of the front passenger’s SRS frontal airbag
depending on the characteristic of the item(s) or person on the front passen-
ger’s seat monitored by the front passenger’s occupant classification system
sensor. For this reason, only the driver’s SRS frontal airbag may deploy in
the event of a collision, but this does not mean failure of the system.
If the front sub sensors and the impact sensors in the airbag control module
detect a predetermined amount of force during a frontal collision, the control
module sends signals to the airbag modu
le(s) (only driver’s module or both
driver’s and front passenger’s modules) instructing the module(s) to inflate
the SRS frontal airbag(s).
The driver’s and front passenger’s SRS frontal airbags use dual stage infla-
tors. The two inflators of each airbag are triggered either sequentially or
simultaneously, depending on the severity of impact, in the case of the
driver’s SRS frontal airbag and depending on the severity of impact and the
characteristic of the item(s) or person on the seat in the case of the front
passenger’s SRS frontal airbag.
After deployment, the SRS airbag immediately starts to deflate so that the
driver’s vision is not obstructed. The time required from detecting impact to
the deflation of the SRS airbag after deployment is shorter than the blink of
an eye.
Both when only the driver’s SRS frontal airbag deploys and the driver’s and
front passenger’s SRS frontal airbags deploy, the driver’s and front passen-
ger’s seat belt pretensioners operate at the same time.
Although it is highly unlikely that the SRS airbag would activate in a non-
accident situation, should it occur, the SRS airbag will deflate quickly, not
obscuring vision and will not interfere with the driver's ability to maintain con-
trol of the vehicle.
When the SRS airbag deploys, a sudden, fairly loud inflation noise will be
heard and some smoke will be released. These occurrences are a normal
result of the deployment. This smoke does not indicate a fire in the vehicle.

80 1-7. Safety information
The driver’s SRS frontal airbag and front passenger’s SRS frontal airbag are
designed to deploy in the event of an accident involving a moderate to
severe frontal collision. They are not designed to deploy in most lesser fron-
tal impacts because the necessary protection can be achieved by the seat
belt alone. Also, they are not designed to deploy in most side or rear impacts
or in most roll-over accidents because deployment of only the driver’s SRS
frontal airbag or both driver’s and front passenger’s SRS frontal airbags
would not help the occupant in those situations. The driver’s and front pas-
senger’s SRS frontal airbags are designed to function on a one-time-only
basis.
SRS airbag deployment depends on the level of force experienced in the
passenger compartment during a collision. That level differs from one type of
collision to another, and it may have no bearing on the visible damage done
to the vehicle itself.
■ Example of accident in which the driver’s/driver’s and front passen-
ger’s SRS frontal airbag(s) will most likely deploy
A head-on collision against a thick concrete wall at a vehicle speeds of 12 to
19 mph (20 to 30 km/h) or higher activates only the driver’s SRS frontal air-
bag or both driver’s and front passenger’s SRS frontal airbags. The airbag(s)
will also be activated when the vehicle is exposed to a frontal impact similar
in fashion and magnitude to the collision described above.

■
Examples of the types of accidents in which it is possible that the
driver’s/driver’s and front passenger’s SRS frontal airbag(s) will deploy
■ Examples of the types of accidents in which deployment of the
driver’s/driver’s and front passenger’ s SRS frontal airbag(s) is unlikely
to occur
There are many types of collisions which might not necessarily require
deployment of driver’s/driver’s and front passenger’s SRS frontal airbag(s).
In the event of accidents like those illustrated, the driver’s/driver’s and front
passenger’s SRS frontal airbag(s) may not deploy depending on the level of
accident forces involved.
Only the driver’s SRS frontal airbag or
both driver’s and front passenger’s SRS
frontal airbags may be activated when the
vehicle sustains a hard impact in the
undercarriage area from the road surface
(such as when the vehicle plunges into a
deep ditch, is severely impacted or
knocked hard against an obstacle on the
road such as a curb).
The vehicle strikes an object, such as a
telephone pole or sign pole.

82 1-7. Safety information
The vehicle slides under the load bed of a
truck.
The vehicle sustains an oblique offset
frontal impact.
The vehicle sustains an offset frontal colli-
sion.
The vehicle strikes an object that can
move or deform, such as a parked vehi-
cle.

■
Examples of the types of accidents in which the driver’s/driver’s and
front passenger’s SRS frontal airb ag(s) will basically not deploy
The driver’s and front passenger’s SRS
frontal airbags are designed not to deploy
in most cases if the vehicle is struck from
the side or from behind, or if it rolls onto
its side or roof, or if it is involved in a low-
speed frontal collision.
First impact
Second impact
In an accident where the vehicle is
impacted more than once, the driver’s
and/or front passenger’s SRS frontal air-
bag(s) will deploy only once on the first
impact.
Example: In the case of a double colli-
sion, first with another vehicle, then
against a concrete wall in immediate suc-
cession, once either or both of the driver’s
and front passenger’s SRS frontal air-
bags is/are activated on the first impact,
it/they will not be activated on the second
impact.

84 1-7. Safety information
CAUTION
■If the SRS airbags deploy
Do not touch the SRS airbag system components around the steering wheel
and dashboard with bare hands right after deployment. Doing so can cause
burns because the components can be very hot as a result of deployment.
■ Child restraint precautions
NEVER INSTALL A REARWARD FACING CHILD SEAT IN THE FRONT
PASSENGER’S SEAT EVEN IF TH E FRONT PASSENGER’S SRS FRON-
TAL AIRBAG IS DEACTIVATED. Be sure to install it in the REAR seat in a
correct manner. Also, it is strongly recommended that any forward facing
child seat or booster seat be installed in the REAR seat, and that even chil-
dren who have outgrown a child restraint system be also seated in the
REAR seat. This is because children sitting in the front passenger’s seat
may be killed or severely injured should the front passenger’s SRS frontal
airbag deploy. REAR seats are the safest place for children.

Before driving
SRS side airbag and SRS curtain shield airbag
The SRS side airbag is stored in the door side of each front seat
seatback, which bears an “SRS AIRBAG” label.
In a moderate to severe side impa ct collision, the SRS side airbag on
the impacted side of the vehicl e deploys between the occupant and
the door panel and supplements the seat belt by reducing the impact
on the occupant’s chest and waist. The SRS side airbag operates
only for front seat occupants.
The SRS curtain shield airbag on each side of the cabin is stored in
the roof side (bet ween the front pillar and a poi nt over the rear seat).
An “SRS AIRBAG” mark is located at the top of each front and rear
pillar.
In a moderate to severe side impa ct collision, the SRS curtain shield
airbag on the impacted side of the vehicle deploys between the occu-
pant and the side window and supplem ents the seat belt by reducing
the impact on the occupant’s head.

86 1-7. Safety information
■Operation
The SRS side airbag and SRS curtain shield airbag can function only when
the engine switch is in the “ON” position.
The driver’s and front passenger’s SRS side airbags and SRS curtain shield
airbags deploy independently of each other since each has its own impact
sensor. Therefore, they may not both deploy in the same accident. Also, the
SRS side airbag and SRS curtain shield airbag deploys independently of the
driver’s and front passenger’s SRS front airbags in the steering wheel and
instrument panel.
An impact sensor, which senses impact force, is located in each of the left
and right center pillars, doors and rear wheel houses. Another impact sen-
sor, which also senses impact force, is located under the center of the rear
seats.
If the impact sensor that is located under the center of the rear seats and
one of the center pillar impact sensors or door impact sensors together
sense an impact force above a predetermined level in a side collision, the
control module causes both the SRS side airbag and curtain shield airbag on
the impacted side to inflate regardless of whether the rear wheel house
impact sensor on the same side senses an impact.
If the impact sensor that is located under the center of the rear seats and
one of the rear wheel house impact sensors together sense an impact force
above a predetermined level, the control module causes only the SRS cur-
tain shield airbag on the impacted side to inflate.
After the deployment, the SRS side airbag immediately starts to deflate. The
time required from detection of an impact to deflation of an SRS side airbag
after deployment is shorter than the blink of an eye.

Before driving
The SRS curtain shield airbag remains inflated for a while following deploy-
ment then slowly deflates.
The SRS side airbag and SRS curtain shield airbag deploy even when no
one occupies the seat on the side on which an impact is applied.
When the SRS side airbag and SRS curtain shield airbag deploy, a sudden,
fairly loud inflation noise will be heard and some smoke will be released.
These occurrences are a normal result of the deployment. This smoke does
not indicate a fire in the vehicle.
The SRS side airbag and SRS curtain shield airbag are designed to deploy
in the event of an accident involving a moderate to severe side impact colli-
sion. They are not designed to deploy in most lesser side impact. Also, they
are not designed to deploy in most frontal or most rear impacts because
SRS side airbag and SRS curtain shield airbag deployment would not help
the occupant in those situations.
Each SRS side airbag and SRS curtain shield airbag are designed to func-
tion on a one-time-only basis.
SRS side airbag and SRS curtain shield airbag deployment depend on the
level of force experienced in the passenger compartment during a side
impact collision. That level differs from one type of collision to another, and it
may have no bearing on the visible damage done to the vehicle itself.
■ Example of the type of accident in which the SRS side airbag and SRS
curtain shield airbag will most likely deploy
■ Examples of the types of accidents in which the SRS side airbag and
SRS curtain shield airbag are unlikely to deploy
There are many types of collisions which might not necessarily require SRS
side airbag and SRS curtain shield airbag deployment. In the event of acci-
dents like those illustrated, the SRS side airbag and SRS curtain shield
air-
bag may not deploy depending on the level of accident forces involved.
A severe side impact near the front seat
activates the SRS side airbag and SRS
curtain shield airbag.
