Passenger Occupant Classification System

First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-36) carefully.

Passenger Occupant Classification Sensor

▼

Your vehicle is equipped with a passenger occupant classification 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 flashes 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.

Type A

If the 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 passenger seat, the sensors might detect the person as being a child depending on

the person's physique.

If the 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 passenger air bag deactivation

indicator light on/off condition chart, do not allow an occupant to sit in the passenger seat

and consult an Authorized Mazda Dealer as soon as possible. The system may not work

properly in an accident.

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 passenger seat, the sensors might detect the person as being a child depending on

the person's physique.

If both of the passenger air bag deactivation indicator lights do not turn on for a specified

period of time when the ignition is switched ON or they do not turn on as indicated in the

passenger air bag deactivation indicator light on/off condition chart, do not allow an

occupant to sit in the 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 passenger's seat tosit with a posture which makes it diꢀcult

for the passenger occupant classiꢁcation sensor to detect the occupant correctly:

Sitting in the passenger's seat with a posture which makes it diꢀcult for the passenger

occupant classiꢁcation sensor to detect the occupant correctly is dangerous. If the passenger

occupant classiꢁcation 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 classiꢁcation 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/oꢂ condition chart. For example:

A passenger is seated as shown in the following ꢁgure:

2-52

Essential Safety Equipment

SRS Air Bags

Luggage or other items placed under the passenger seat or between the passenger seat and

driver seat that push up the passenger seat bottom.

An object, such as a seat cushion, is put on the passenger's seat or between the passenger's

back and the seatback.

A seat cover is put on the passenger's seat.

Luggage or other items are placed on the seat with the child in the child-restraint system.

The seat is washed.

Liquids are spilled on the seat.

The passenger seat is moved backward, pushing into luggage or other items placed behind

it.

Luggage or other items are placed between the passenger seat and driver seat.

An electric device is put on the passenger's seat.

An additional electrical device, such as a seat warmer is installed to the surface of the

passenger seat.

The passenger front and side air bags and seat belt pretensioner systems will deactivate if the

passenger air bag deactivation indicator light turns on.

CAUTION

To assure proper deployment of the front air bag and to prevent damage to the sensor in

the seat cushion:

Do not place sharp objects on the seat cushion or leave heavy luggage on them.

Do not spill any liquids on the seats or under the seats.

To allow the sensors to function properly, always perform the following:

Adjust the seats as far back as possible and always sit upright against the seatbacks with

seat belts worn properly.

If you place your child on the passenger seat, secure the child-restraint system properly

and slide the passenger seat as far back as possible.

NOTE



The system requires about 10 seconds to alternate between turning the passenger front

and side air bags and seat belt pretensioner system on or off.

The passenger air bag deactivation indicator light may turn on repeatedly if luggage or



other items are put on the passenger seat, or if the temperature of the vehicle's interior

changes suddenly.

The passenger air bag deactivation indicator light may turn on for 10 seconds if the



electrostatic capacity on the passenger seat changes.

The air bag/seat belt pretensioner system warning light might turn on if the passenger



seat receives a severe impact.

If the passenger air bag deactivation indicator light does not turn on after installing a



child-restraint system on the passenger seat, first, re-install your child-restraint system

according to the procedure in this owner's manual. Then, if the passenger air bag

deactivation indicator light still does not turn on, and consult an Authorized Mazda

Dealer as soon as possible.



If the passenger air bag deactivation indicator light turns on when an occupant is seated

directly in the passenger seat, have the passenger re-adjust their posture by sitting with

their feet on the floor, and then re-fastening the seat belt. If the passenger air bag

deactivation indicator light remains turned on, slide the passenger seat as far back as

possible. Consult an Authorized Mazda Dealer as soon as possible.
