Before driving
SRS airbags
The SRS airbags inflate when the vehicle is subjected to certain
types of severe impacts that may cause significant injury to the
occupants. They work together with the seat belts to help reduce the
risk of death or serious injury.
Front airbags
SRS driver airbag/front passenger airbag
Can help protect the head and ches t of the driver and front pas-
senger from impact with interior components.
SRS knee airbags
Can help provide driver and front passenger protection.
SRS seat cushion airbags
Can help restrain the driver and front passenger.

66 1-7. Safety information
Side and curtain shield airbags
SRS side airbags
Can help protect the torso of the front seat occupants.
SRS curtain shield airbags
Can help protect primarily the head of occupants.
SRS rear window curtain shield airbag
Can help protect primarily the head of rear occupants.

68 1-7. Safety information
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
sensor assembly (ECU) controls ai rbag deployment based on infor-
mation obtained from the sensors etc. shown in the system compo-
nents diagram above. This inform ation includes crash severity and
occupant information. As the air bags deploy, a chemical reaction in
the inflators quickly fills the airbag s with non-toxic gas to help restrain
the motion of the occupants.
■ If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, and parts of the front and rear pillars, roof side
rail and rear roof headlining may be hot for several minutes. The airbag
itself may also be hot.
● The front windshield may crack.
■ Operating conditions (SRS front airbags)
●The SRS front airbags and SRS seat cushion airbags will deploy in the
event of an impact that exceeds the set threshold level (the level of force
corresponding to an approximately 12-18 mph [20-30 km/h] frontal colli-
sion 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 collision (e.g.
a collision in which the front of the vehicle “underrides”, or goes under, the
bed of a truck, etc.).
● Depending on the type of collision, it is possible that only the seat belt
pretensioners will activate.
● The SRS front airbags and seat cushion airbag for the front passenger
will not activate if there is no passenger sitting in the front passenger
seat. However, the SRS front airbags and seat cushion airbag for the
front passenger may deploy if luggage is put in the seat, even if the seat
is unoccupied. ( P. 79)

Before driving
●
The SRS seat cushion airbags on the front seats will not operate if the
occupant is not wearing a seat belt.
■ Operating conditions (SRS side ai rbags and SRS curtain shield air-
bags)
● The SRS side airbags and SRS curtain shield airbags will deploy in the
event of an impact that exceeds the set threshold level (the level of force
corresponding to the impact force produced by an approximately 3300 lb.
[1500 kg] vehicle colliding with the vehicle cabin from a direction perpen-
dicular to the vehicle orientation at an approximate speed of 12-18 mph
[20-30 km/h]).
● The SRS curtain shield airbags may also deploy in the event of a severe
frontal collision.
■ Operating conditions (SRS rear window curtain shield airbag)
The SRS rear window curtain shield airbag is designed to inflate when the
passenger compartment is subjected to a severe impact from the rear or
side.
■ Conditions under which the SRS airbags may deploy (inflate), other
than a collision
Front airbags
The SRS front airbags may also deploy if a serious impact occurs to the
underside of your vehicle. Some examples are shown in the illustration.
● Hitting a curb, edge of pavement or
hard surface
● Falling into or jumping over a deep hole
● Landing hard or vehicle falling

70 1-7. Safety information
Rear window curtain shield airbag
The SRS rear window curtain shield airbag may also deploy if a serious
impact occurs to the underside of your vehicle. Some examples are shown
in the illustration.
■ Types of collisions that may not depl oy the SRS airbag (SRS front air-
bags)
The SRS front airbags and SRS seat cushion airbags are generally 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. But, whenever a colli-
sion of any type causes sufficient forward deceleration of the vehicle,
deployment 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
●Collision from the side
● Collision from the rear
● Vehicle rollover

■
Types of collisions that may not deploy the SRS airbag
(SRS side airbags and SRS curtain shield airbags)
The SRS side airbags and curtain shield airbags system may not activate if
the vehicle is subjected to a collision from the side at certain angles, or a col-
lision to the side of the vehicle body other than the passenger compartment.
The SRS side airbags and curtain shield airbags are not generally designed
to inflate if the vehicle is involved in a frontal or rear collision, if it rolls over,
or if it is involved in a low-speed side collision.
■ Types of collisions that may not deploy the SRS airbag
(SRS rear window curtain shield airbag)
The SRS rear window curtain shield airbag is generally not designed to
inflate if the vehicle is involved in a front collision, if it rolls over, or if it is
involved in a low-speed rear collision.
● Collision from the side to the vehicle
body other than the passenger com-
partment
● Collision from the side at an angle
●Collision from the front*
●Collision from the rear
● Vehicle rollover
*: Depending on the conditions and type
of accident, the curtain shield airbags
may deploy (inflate) upon frontal
impact.
● Collision from the front
● Vehicle rollover

72 1-7. Safety information
■When to contact your Scion dealer
In the following cases, contact your Scion dealer as soon as possible.
●Any of the SRS airbags have been inflated.
●The front of the vehicle is damaged or
deformed, or was involved in an acci-
dent that was not severe enough to
cause the SRS front airbags and SRS
seat cushion airbags to inflate.
● A portion of a door is damaged or
deformed, or the vehicle was involved
in an accident that was not severe
enough to cause the SRS side airbags
and curtain shield airbags to inflate.
● The rear of the vehicle is damaged or
deformed, or the vehicle was involved
in an accident that was not severe
enough to cause the SRS rear window
curtain shield airbag to inflate.
● The pad section of the steering wheel
or dashboard near the front passenger
airbag cover or lower portion of the
instrument panel is scratched, cracked,
or otherwise damaged.
