CAUTION

■

While driving

●

Do not adjust the position of the driver’s seat.
Doing so could cause the driver to lose control of the vehicle.

●

Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce
the effectiveness of the seat belt and head restraint, increasing the risk of
death or serious injury to the driver or passenger.

●

Do not place anything under the front seats.
Objects placed under the front seats may become jammed in the seat
tracks and stop the seat from locking in place. This may lead to an acci-
dent, resulting in death or serious injury. The adjustment mechanism may
also be damaged.

■

Adjusting the seat position

●

Take care when adjusting the seat position to ensure that other passen-
gers are not injured by the moving seat.

●

Do not put your hands under the seat or near the moving parts to avoid
injury.
Fingers or hands may become jammed in the seat mechanism.

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.

SRS front airbags

SRS driver airbag/front passenger airbag
Can help protect the head and chest of the driver and front pas-
senger from impact with interior components

SRS side and curtain shield airbags

Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
sensor assembly (ECU) controls airbag deployment based on infor-
mation obtained from the sensors etc. shown in the system compo-
nents diagram above. This information includes crash severity and
occupant information. As the airbags deploy, a chemical reaction in
the inflators quickly fills the airbags 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, parts of the front and rear pillars, and roof side
rails, may be hot for several minutes. The airbag itself may also be hot.

●

The windshield may crack.

■

SRS airbag deployment conditions (SRS front airbags)

●

The SRS front airbags will deploy in the event of an impact that exceeds
the set threshold level (the level of force corresponding to an approxi-
mately 12 - 18 mph [20 - 30 km/h] 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 and 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 passenger airbag will not activate if there is no passenger
sitting in the front passenger seat. However, the SRS front passenger air-
bag may deploy if luggage is put in the seat, even if the seat is unoccu-
pied. (

P. 81)

■

SRS airbag deployment conditions (SRS side airbags and curtain
shield airbags)

●

The SRS side and curtain shield airbags will deploy in the event of an
impact that exceeds the set threshold level (the level of force corre-
sponding 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.

■

Conditions under which the SRS airbags may deploy (inflate), other
than a collision

The SRS front airbags and SRS curtain shield airbags 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 deploy the SRS airbags (SRS front air-
bags)

The SRS front 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 collision of any type causes suffi-
cient forward deceleration of the vehicle, deployment of the SRS front air-
bags may occur.

●

Hitting a curb, edge of pavement or
hard surface

●

Falling into or jumping over a deep hole

●

Landing hard or falling

●

Collision from the side

●

Collision from the rear

●

Vehicle rollover

■

Types of collisions that may not deploy the SRS airbags (SRS side air-
bags and curtain shield airbags)

The SRS side airbags and curtain shield airbag 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 do not generally 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.

The SRS curtain shield airbags do not generally inflate if the vehicle is
involved in a rear collision, if it rolls over, or if it is involved in a low-speed
side or low-speed frontal 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

●

deformed, or was involved in an acci-
dent that was not severe enough to
cause the SRS 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 pad section of the steering wheel
or dashboard near the front passenger
airbag cover is scratched, cracked, or
otherwise damaged.

●

The surface of the seats with the side
airbag is scratched, cracked, or other-
wise damaged.

■

SRS airbag precautions

Observe the following precautions regarding the SRS 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 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 pro-
vides 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 the

pedals 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.

■

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. 87)

●

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.

■

SRS airbag precautions

●

Do not use seat accessories which cover the parts where the SRS side
airbags inflate as they may interfere with inflation of the airbags. Such
accessories may prevent the side airbags from activating correctly, disable
the system or cause the side airbags to inflate accidentally, resulting in
death or serious injury.

●

Do not strike or apply significant levels of force to the area of the SRS air-
bag components.
Doing so can cause the SRS airbags to malfunction.

●

Do not touch any of the component parts immediately after the SRS air-
bags have deployed (inflated) as they may be hot.

●

Do not attach anything to or lean any-
thing against areas such as the dash-
board or steering wheel pad. 
These items can become projectiles
when the SRS driver and front passen-
ger airbags deploy.

●

Do not attach anything to areas such as
a door, windshield glass, side door
glass, front and rear pillars, roof side
rail or assist grip.

●

Do not hang coat hangers or other hard
objects on the coat hooks. All of these
items could become projectiles and
may cause death or serious injury,
should the SRS curtain shield airbags
deploy.

SRS airbag precautions

●

If breathing becomes difficult after the SRS airbags have deployed, open a
door or window to allow fresh air in, or leave the vehicle if it is safe to do
so. Wash off any residue as soon as possible to prevent skin irritation. 

●

If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked, have
them replaced by your Scion dealer.

■

Modification and disposal of SRS airbag system components

Do not dispose of your vehicle or perform any of the following modifications
