Front Passenger Occupant Classification

System

Your vehicle is equipped with a front passenger occupant classifica-
tion sensor as a part of the supplemental 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 system 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 deactivates 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 passenger 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 malfunction. If this happens, the front
passenger front and side air bags and seat belt pretensioner system
will not deploy.

First, please read “Supplemental 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 classification 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:

: 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.

: If a smaller adult sits on the front passenger seat, the sensors might detect

the person as being a child depending on the person’s physique.

The curtain air bag is ready for inflating regardless of what the front
passenger air bag deactivation indicator light on/off condition chart
indicates.

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.

Essential Safety

WARNING

■

Do not allow an occupant in the front passenger’s seat to sit with a
posture which makes it difficult for the front passenger occupant clas-
sification sensor to detect the occupant correctly
Sitting in the front passenger’s seat with a posture which makes it difficult
for the front passenger occupant classification sensor to detect the occu-
pant correctly is dangerous. If the front passenger occupant classification
sensor cannot detect the occupant sitting on the front passenger’s seat cor-
rectly, the front passenger front and side air bags and pretensioner system
may not operate (deploy) or they may operate (deploy) accidentally. The
front passenger will not have the supplementary protection of the air bags or
the accidental operation (deployment) of the air bags could result in serious
injury or death. Under the following conditions, the front passenger occu-
pant classification sensor cannot detect a passenger sitting on the front
passenger’s seat correctly and the deployment/non-deployment of the air
bags cannot be controlled as indicated in the front passenger air bag deac-
tivation indicator light on/off condition chart. For example:

●

A front passenger is seated as shown in the following figure:

●

A rear passenger pushes up on the front passenger seat with their feet.

●

Luggage or other items placed under the front passenger seat or between
the front passenger seat and driver seat that push up the front passenger
seat bottom.

●

An object, such as a seat cushion, is put on the front passenger’s seat or
between the passenger’s back and the seatback.
