Front Passenger Occupant Classification System

*

First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-45) carefully.

▼ Front Passenger Occupant Classification Sensor

Your vehicle is equipped with a front passenger occupant classification sensor as a part of
the supplemental restraint system. This sensor 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 indicator 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.

Front passenger air bag deactivation indicator light

This indicator light turns on to remind you that the front passenger 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:

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 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 an Authorized Mazda Dealer as soon as possible. The system may not work
properly in an accident.

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 classification 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 occupant correctly is dangerous. If the
front passenger occupant classification sensor cannot detect the occupant sitting on the front
passenger's seat correctly, the front passenger front and side air bags and pretensioner
system may not operate (non-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 occupant 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 deactivation indicator light on/off condition chart. For example:
