Essential Safety Equipment
◆Front Passenger Air Bag
The front passenger air bag is mounted in the front passenger
dashboard.
The inflation mechanism for the
front passenger air bag is the
same as the driver’s air bag, as
mentioned above.
For more details about air bag
deployment, refer to “SRS Air
Bag Deployment Criteria”
( P. 74).
In addition, the front passenger air bag is designed to only deploy
when the front passenger occupant classification sensor detects a
passenger sitting on the front passenger’s seat. For details, refer to
the front passenger occupant classification system (P. 78).
◆Side Air Bags
The side air bags are mounted in the outboard sides of the front
seatbacks.
When the air bag crash sensors
detect a side impact of greater
than moderate force, the sys-
tem inflates the side air bag
only on the side in which the
vehicle was hit. The side air
bag inflates quickly to reduce
injury to the driver or front pas-
senger’s chest caused by
directly hitting interior parts
such as a door or window.
For more details about air bag deployment, refer to “SRS Air Bag
Deployment Criteria” ( P. 7 4 ) .
In addition, the front passenger side bag is designed to only deploy
when the front passenger occupant classification sensor detects a
passenger sitting on the front passenger’s seat. For details, refer to
the front passenger occupant classification system (P. 78).

◆Curtain Air Bags
The curtain air bags are mounted in the front and rear window pil-
lars, and the roof edge along both sides.
When the air bag crash sensors detect a side impact of greater
than moderate force, the curtain ai r bag inflates quickly and helps to
reduce injury mainly to the rear outboard passenger’s head caused
by directly hitting interior pa rts such as a door or window.
For more details about air bag deployment, refer to “SRS Air Bag
Deployment Criteria” ( P. 7 4 ) .
In a side impact
Greater than moderate impact to one side of the vehicle will cause
the curtain air bag on that side only to inflate.
Only one side curtain air bag
will deploy on the side of the
vehicle that receives the force
of an impact.
In a roll-over
In response to a vehicle roll-over, both curtain air bags inflate.
Both curtain air bags will deploy
after the roll-over accident is
detected.

X: The SRS air bag equipment is designed to deploy in a collision.
*1:The front passenger front and side air bags and the seat belt pretensioner
are designed to deploy when the front passenger occupant classification
sensor detects a passenger sitting on the front passenger’s seat.
*2:In a side collision, the seat belt pretensioners and the side/curtain air bags
deploy (only on the side in which the collision occurs).
*3:In a roll-over accident, the seat belt pretensioners and the curtain air bags
deploy.
In a frontal offset collision, the equipped air bags and pretensioners may all
deploy depending on the direction, angle, and rate of impact.

Limitations to SRS Air Bag
The following illustrations are examples of front/near front collisions
that may not be detected as severe enough to deploy the SRS air bag
equipment.
Impacts involving trees or poles
Frontal offset impact to the vehicle
Rear-ending or running under a
truck’s tail gate
In severe collisions such as those described previously in “SRS
Air Bag Deployment Cr iteria”, the applicable SRS air bag equip-
ment will deploy. However, in some accidents, the equipment
may not deploy depending on the ty pe of collision and its sever-
ity.

Front Passenger Occupant Classification
System
Your vehicle is equipped with a front passenger occupant classifica-
tion sensor as a part of the supple mental restraint system. This sen-
sor is equipped in the front passenger’s seat cushion. This sensor
measures the electrostatic capacity of the front passenger’s seat. The
SAS unit is designed to prevent the front passenger front and side air
bags and seat belt pretensioner syst em from deploying if the front
passenger air bag deactivation indicator light turns on.
To reduce the chance of injuries caused by deployment of the front
passenger air bag, the system deac tivates the front passenger front
and side air bags and also the seat belt pretensioner system when the
front passenger air bag deactivation indicator light turns on. Refer to
the following table for the front passenger air bag deactivation indica-
tor light illumination conditions.
This system shuts off the front pa ssenger front and side air bags and
seat belt pretensioner system, so make sure the front passenger air
bag deactivation indicator light turns on according to the following
table.
The air bag/front seat belt pretensioner system warning light flashes
and the front passenger air bag deactivation indicator light illuminates
if the sensors have a possible malfun ction. If this happens, the front
passenger front and side air bags and seat belt pretensioner system
will not deploy.
First, please read “Supplementa l Restraint System (SRS) Pre-
cautions” ( P. 62) carefully.

■Front passenger air bag deactivation indicator light
This indicator light turns on to
remind you that the front pas-
senger front and side air bags
and seat belt pretensioner will
not deploy during a collision.
If the front passenger occupant clas sification sensor is normal, the
indicator light turns on when the ignition is switched ON. The light
turns off after a few seconds. Then, the indicator light turns on or is
off under the following conditions:

*1: The occupant classification sensor may not detect a child seated on the seat, in a child-restraint system, or a junior seat depending on the child’s
physical size and seated posture.
*2: If a smaller adult sits on the front passenger seat, the sensors might detectthe person as being a child depending on the person’s physique.

If the front passenger air bag deactivation indicator light does not
turn on when the ignition is switched ON and does not turn on as
indicated in the front passenger air bag deactivation indicator light
on/off condition chart, do not allow an occupant to sit in the front
passenger seat and consult your Scion dealer as soon as possible.
The system may not work properly in an accident.
● The system requires about 10 seconds to alternate between turning the
front passenger front and side air bags and seat belt pretensioner system on
or off.
● The front passenger air bag deactivation indicator light may turn on repeat-
edly if luggage or other items are put on the front passenger seat, or if the
temperature of the vehicle’s interior changes suddenly.
● The front passenger air bag deactivation indicator light may turn on for 10
seconds if the electrostatic capacity on the front passenger seat changes.
● The air bag/front seat belt pretensioner system warning light might turn on if
the front passenger seat receives a severe impact.
● If the front passenger air bag deactivation indicator light does not turn on
after installing a child-restraint system on the front passenger seat, first, re-
install your child-restraint system according to the procedure in this owner’s
manual. Then, if the front passenger air bag deactivation indicator light still
does not turn on, install the child-restraint system on the rear seat and con-
sult your Scion dealer as soon as possible.
● If the front passenger air bag deactivation indicator light turns on when an
occupant is seated directly in the front passenger seat, have the passenger
re-adjust their posture by sitting with their feet on the floor, and then re-fas-
tening the seat belt. If the front passenger air bag deactivation indicator light
remains turned on, move the passenger to the rear seat. If sitting in the rear
seat is not possible, slide the front passenger seat as far back as possible.
Consult your Scion dealer as soon as possible.
