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 deploy 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

●

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 do not generally inflate if the vehicle is involved in a
frontal collision, if it rolls over, or if it is involved in a low-speed side or low-
speed rear collision.

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

CAUTION

■

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 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 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.

●

Do not sit on the edge of the seat or
lean against the dashboard.

78

CAUTION

■

SRS airbag precautions

●

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.

●

Do not allow anyone to kneel on the
passenger seat toward the door or put
their head or hands outside the vehicle.

●

Do not allow anyone to kneel on the
rear seat toward the back door.

■

SRS airbag precautions

●

If a vinyl cover is put on the area where the SRS knee airbags will deploy,
be sure to remove it.

●

Do not use seat accessories which cover the parts where the SRS side
airbags and SRS seat cushion airbags inflate as they may interfere with
inflation of the airbags. Such accessories may prevent the side airbags
and seat cushion airbags from activating correctly, disable the system or
cause the side airbags and seat cushion 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 attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad and lower
portion of the instrument panel. 
These items can become projectiles
when the SRS driver, front passenger
and knee airbags deploy.

●

Do not attach anything to areas such as
the door, windshield glass, side door
glass, front and rear pillars, roof side
rail or assist grip. (Except for the speed
limit label 

P. 295)

●

Do not attach any heavy, sharp or hard
objects such as keys or accessories to
the key. The objects may restrict the
SRS knee airbags inflation or be thrust
into the driver’s seat area by the force
of the deploying airbag, thus causing a
danger.

CAUTION

■

SRS airbag precautions

●

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

●

If breathing becomes difficult after the SRS airbag has 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
without consulting your Scion dealer. 
The SRS airbags may malfunction or deploy (inflate) accidentally, causing
death or serious injury.

●

Installation, removal, disassembly and repair of the SRS airbags.

●

Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, side and rear
pillars or roof side rail.

●

Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment.

●

Installation of snow plows, winches, etc. to the front grille (bull bars, kan-
garoo bar etc.).

●

Installation of racks etc. to the back door (strap racks, bicycle rack etc.).

●

■

Front passenger occupant classification system precautions

Observe the following precautions regarding front passenger occupant clas-
sification system. 
Failure to do so may cause death or serious injury.

●

Wear the seat belt properly.

●

Make sure the front passenger’s seat belt tab has not been left inserted
into the buckle before someone sits in the front passenger seat.

●

Make sure the AIR BAG OFF indicator light is not illuminated when using
the seat belt extender for the front passenger seat. If the AIR BAG OFF
indicator light is illuminated, disconnect the extender tongue from the seat
belt buckle, then reconnect the seat belt. Reconnect the seat belt extender
after making sure the AIR BAG ON indicator light is illuminated. If you use
the seat belt extender while the AIR BAG OFF indicator light is illuminated,
the SRS airbags for the passenger may not activate correctly, which could
cause death or serious injury in the event of collision.

●

Do not apply a heavy load to the front passenger seat or equipment.

●

Do not put weight on the front passenger seat by putting your hands or
feet on the front passenger seat seatback from the rear passenger seat.

●

Do not let a rear passenger lift the front passenger seat with their feet or
press on the seatback with their legs.

●

Do not put objects under the front passenger seat.

●

Do not recline the front passenger seatback so far that it touches a rear
seat. This may cause the AIR BAG OFF indicator light to be illuminated,
which indicates that the passenger’s airbags will not deploy in the event of
a severe accident. If the seatback touches the rear seat, return the seat-
back to a position where it does not touch the rear seat. Keep the front
passenger seatback as upright as possible when the vehicle is moving.
Reclining the seatback excessively may lessen the effectiveness of the
seat belt system.

86

1-7. Safety information

CAUTION

■

Front passenger occupant classification system precautions

●

If an adult sits in the front passenger seat, the AIR BAG ON indicator light
is illuminated. If the AIR BAG OFF indicator is illuminated, ask the passen-
ger to sit up straight, well back in the seat, feet on the floor, and with the
seat belt worn correctly. If the AIR BAG OFF indicator still remain illumi-
nated, either ask the passenger to move to the rear seat, or if that is not
possible, move the front passenger seat fully rearward.

●

When it is unavoidable to install the forward-facing child restraint system
on the front passenger seat, install the child restraint system on the front
passenger seat in the proper order. (

P. 92)

●

Do not modify or remove the front seats.

●

Do not kick the front passenger seat or subject it to severe impact. Other-
wise, the SRS warning light may come on to indicate a malfunction of the
detection system. In this case, contact your Scion dealer immediately.

●

Child restraint systems installed on the rear seat should not contact the
front seatbacks.

●

Do not use a seat accessory, such as a cushion and seat cover, that cov-
ers the seat cushion surface.

●

Do not modify or replace the upholstery of the front seat.

Before driving

Child restraint systems

Points to remember

Studies have shown that installing a child restraint on a rear seat is
much safer than installing one to the front passenger seat.

● Choose a child restraint system that suits your vehicle and is

appropriate to the age and size of the child.

● For installation details, follow the instructions provided with the

child restraint system. 
General installation instructions are provided in this manual. 
(

P. 92)

Types of child restraints

Child restraint systems are classified into the following 3 types
according to the age and size of the child.

Rear facing — Infant seat/convertible seat

A child restraint system for a small child or baby must itself be prop-

erly restrained on the seat with the lap portion of the lap/shoulder

belt.

The laws of all 50 states of the U.S.A. and Canada now require the

use of child restraint systems.
