Driver and Passenger Occupant Classification System
First, please read“Supplemental Restraint System (SRS) Precautions ”(page 2-30)
carefully.
q Driver Seat Slide Position Sensor
Your vehicle is equipped with a driver seat slide position sensor as a part of the
supplemental restraint system. The sensor is located under the driver seat. The sensor
determines whether the driver seat is fore or aft of a reference position and sends the seat
position to the diagnostic module (SAS unit). The SAS unit is designed to control the
deployment of the driver air bag depending on how close the driver seat is to the steering
wheel.
The air bag/seat belt pretensioner system warning light flashes if the sensor has a possible
malfunction (page 2-38).
qPassenger Seat Weight Sensors
Your vehicle is equipped with a passenger seat weight sensors as a part of the supplemental
restraint system. These sensors are located under both of the passenger seat rails. These
sensors determine the total seated weight on the passenger seat and monitor the seat belt
buckle for the passenger 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 illuminates.
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 illuminates. 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 illuminates
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 illuminates to remind you that the passenger front and side air bags and
seat belt pretensioner will not deploy during a collision.
If the passenger weight sensors are normal, the indicator light illuminates when the ignition
is switched ON. The light turns off after a few seconds.

If the passenger air bag has been deactivated using the key, the passenger air bag deactivation indicator light will
remain illuminated as long you leave the passenger air bag turned off, and the chart above no longer applies.
Refer to Passenger Air Bag Deactivation Switch on page 2-43.
*1 : If the passenger seat belt is buckled, the passenger air bag deactivation indicator light illuminates, however this does not indicate a malfunction.
*2 : If a larger child sits on the passenger seat, the sensors might detect the child as being an adult depending on the child's physique.
*3 : 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 illuminate when the ignition is
switched ON and does not illuminate as indicated in the above chart, do not allow a child
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. You must deactivate the passenger air

WARNING
Do not decrease the total seated weight on the passenger seat:When an adult or large child sits on the passenger seat, decreasing the total seated
weight on the passenger seat required for air bag deployment is dangerous. The
passenger seat weight sensors will detect the reduced total seated weight condition
and the passenger front and side air bags and seat belt pretensioner system will not
deploy during an accident. The passenger will not have the supplementary protection
of the air bag, which could result in serious injury. Decreasing the total seated
weight on the passenger seat could result in an air bag not deploying under the
following conditions, for example:
ØLuggage or other items placed under the passenger seat or between the passenger
seat and center console that push up the passenger seat bottom.
Ø The passenger seat occupant sits in a manner such that the occupant's entire
weight is not placed on the seat sitting too close to the door.
Ø Any accessories which might decrease the total seated weight on the passenger
seat are attached to 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 illuminates.
Do not increase the total seated weight on the passenger seat: When an infant or small child sits on the passenger seat, increasing the total seated
weight on the passenger seat is dangerous. The passenger seat weight sensors will
detect the increased total seated weight, which could result in the unexpected
deployment of the passenger front and side air bags and seat belt pretensioner
system in an accident and may cause serious injury. Increasing the total seated
weight on the passenger seat could result in the passenger front and side air bags
and seat belt pretensioner system deployment in an accident under the following
conditions, for example:
ØThe passenger air bag deactivation indicator light does not illuminate when
seating a child in the child-restraint system.
Ø Luggage or other items are placed on the seat with the child in the child-restraint
system.
Ø The seat is washed.
Ø Liquids are spilled on the seat.
Ø The passenger seat is moved backward, and it is pushed into luggage or other
items placed behind it.
Ø Luggage or other items are placed between the passenger seat and center
console.
Ø Any accessories which might increase the total seated weight on the passenger
seat are attached to 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 illuminates.

CAUTION
ØTo assure proper deployment of the front air bag and to prevent damage to the
sensors in the seat bottoms:
ØDo not place sharp objects on the seat bottoms or leave heavy luggage on
them.
ØDo not spill any liquids on the seats or under the seats.
Ø To allow the sensors to function properly, always perform the following:
ØAdjust the seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.
ØIf 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
lThe system requires about 10 seconds to alternate between turning the passenger front and side
air bags and seat belt pretensioner system on or off.
lThe passenger air bag deactivation indicator light may illuminate repeatedly if luggage or other
items are put on the passenger seat, or if the temperature of the vehicle's interior changes
suddenly.
lThe passenger air bag deactivation indicator light may illuminate for 10 seconds if the total
seated weight on the passenger seat changes.
lThe air bag seat belt pretensioner system warning light might illuminate if the passenger seat
receives a severe impact.
lYou must deactivate the passenger air bag using the key (page 2-43) and consult an Authorized
Mazda Dealer.
lIf the passenger air bag deactivation indicator light illuminates when an adult is seated 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 still
illuminates, slide the passenger seat as far back as possible.
q Driver and Passenger Buckle Switches
The buckle switches on the front seat belts detect whether or not the front seat belts are
securely fastened and further control the deployment of the air bags.
