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.

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

SRS airbag precautions
Observe the following precautions regarding the airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts
properly.
The SRS airbags are supplemental devices to be used with the seat belts.
●The front seat cushion surface is
scratched, cracked, or otherwise dam-
aged.
● The surface of the seats with the side
airbags are scratched, cracked or oth-
erwise damaged.
● The portion of the front pillars, rear pil-
lars or roof side rail garnishes (padding)
containing the curtain shield airbags
inside are scratched, cracked or other-
wise damaged.
● The portion of the rear roof headlining
or rear pillars containing the rear win-
dow curtain shield airbag is scratched,
cracked or otherwise damaged.

74 1-7. Safety information
CAUTION
■SRS airbag precautions
●The SRS driver airbag deploys with considerable force, and can cause
death or serious injury especially if the driver is very close to the airbag.
The National Highway Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of
inflation, placing yourself 10 in. (250 mm) from your driver airbag provides
you with a clear margin of safety. This distance is measured from the center
of the steering wheel to your breastbone. If you sit less than 10 in. (250 mm)
away now, you can change your driving position in several ways:
• Move your seat to the rear as far as you can while still reaching thepedals comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many drivers can achieve the 10 in.
(250 mm) distance, even with the driver seat all the way forward, sim-
ply by reclining the back of the seat somewhat. If reclining the back of
your seat makes it hard to see the road, raise yourself by using a firm,
non-slippery cushion, or raise the seat if your vehicle has that feature\
.
• If your steering wheel is adjustable, tilt it downward. This points the air- bag toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while still
maintaining control of the foot pedals, steering wheel, and your view of the
instrument panel controls.
● If the seat belt extender has been con-
nected to the front seat belt buckles but
the seat belt extender has not also
been fastened to the latch plate of the
seat belt, the SRS front airbags will
judge that the driver and front passen-
ger are wearing the seat belt even
though the seat belt has not been con-
nected. In this case, the SRS front air-
bags may not activate correctly in a
collision, resulting in death or serious
injury in the event of a collision. Be sure
to wear the seat belt with the seat belt
extender.

CAUTION
■
SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
● Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too small
to use a seat belt should be properly secured using a child restraint sys-
tem. Scion strongly recommends that all infants and children be placed in
the rear seats of the vehicle and properly restrained. The rear seats are
safer for infants and children than the front passenger seat. ( P. 85)
●Do not sit on the edge of the seat or
lean against the dashboard.
● Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
● Do not allow the front seat occupants to
hold items on their knees.
● Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.
