Passenger Occupant Classi¿ cation System *
First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-24 )
carefully.
Passenger Occupant Classi¿ cation Sensor
Your vehicle is equipped with a passenger occupant classi¿ cation sensor as a part of the
supplemental restraint system. This sensor is equipped in the passenger's seat cushion. This
sensor measures the electrostatic capacity of the passenger's seat. The SAS unit is designed
to prevent the passenger front and side air bags and seat belt pretensioner system from
deploying if the passenger air bag deactivation indicator light turns on.
To reduce the chance of injuries caused by deployment of the passenger air bag, the system
deactivates the passenger front and side air bags and also the seat belt pretensioner system
when the passenger air bag deactivation indicator light turns on. Refer to the following table
for the passenger air bag deactivation indicator light illumination conditions.

This system shuts off the passenger front and side air bags and seat belt pretensioner system,
so make sure the passenger air bag deactivation indicator light turns on according to the
following table.

The air bag/seat belt pretensioner system warning light À ashes and the passenger air bag
deactivation indicator light illuminates if the sensors have a possible malfunction. If this
happens, the passenger front and side air bags and seat belt pretensioner system will not
deploy.
Passenger air bag deactivation indicator light
This indicator light turns on to remind you that the passenger front and side air bags and seat
belt pretensioner will not deploy during a collision.

WARNING
Do not allow an occupant in the passenger's seat to sit with a posture which makes
it diffi cult for the passenger occupant classifi cation sensor to detect the occupant
correctly:
Sitting in the passenger's seat with a posture which makes it diffi cult for the passenger
occupant classifi cation sensor to detect the occupant correctly is dangerous. If the
passenger occupant classifi cation sensor cannot detect the occupant sitting on the
passenger's seat correctly, the passenger front and side air bags and pretensioner system
may not operate (non-deploy) or they may operate (deploy) accidentally. The 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 passenger occupant classifi cation sensor cannot
detect a passenger sitting on the passenger's seat correctly and the deployment/non-
deployment of the air bags cannot be controlled as indicated in the passenger air bag
deactivation indicator light on/off condition chart. For example:




¾ A passenger is seated as shown in the following fi gure:
