Driver and Front Passenger Occupant Classification System

First, please read “Supplemental Restraint System (SRS) Precautions” carefully.

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/front seat belt pretensioner system warning light flashes if the sensor has a
possible malfunction (Air Bag/Front Seat Belt Pretensioner System Warning Light).

Front Passenger SeatWeight Sensors

Your vehicle is equipped with a front passenger seat weight sensors as a part of the
supplemental restraint system. These sensors are located under both of the front passenger
seat rails. These sensors determine the total seated weight on the front passenger 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 total seated weight is less than approximately 30
kg (66 lb).

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:

- There is no passenger in the front passenger seat. (The front passenger air bag
deactivation indicator light does not illuminate.).

- The total seated weight on the front passenger seat is less than approximately 30 kg (66
lb). (The front passenger air bag deactivation indicator light illuminates.).

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 illuminates
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.

This indicator light illuminates 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 weight sensors are normal, the indicator light illuminates when the
ignition switch is turned to the ON position. For a specified of time it goes out.

The front passenger air bag deactivation indicator light illuminates or is off under the following conditions:

* If the front passenger seat belt is buckled, the front passenger air bag


* If the front passenger seat belt is buckled, the front passenger air bag deactivation indicator light illuminates, however this does not indicate a malfunction.

Curtain air bag is ready for inflating despite the chart above.

If the front passenger air bag deactivation indicator light does not illuminate when the
ignition switch is turned to the ON position and does not illuminate as indicated in the
above chart, do not allow a child 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 decrease the total seated weight on the front passenger seat: When an adult or large child sits on the front passenger seat, decreasing the total
seated weight on the front passenger seat from the total seated weight of approximately 42 kg (93 lb) required for air bag deployment is dangerous. The front
passenger seat weight sensors will detect the reduced total seated weight condition
and the front passenger front and side air bags and seat belt pretensioner system
will not deploy during an accident. The front passenger will not have the supplementary protection of the air bag, which could result in serious injury.

Decreasing the total seated weight on the front passenger seat from the total seated
weight of approximately 42 kg (93 lb) could result in an air bag not deploying under
the following conditions, for example: Luggage or other items placed under the front passenger seat or between the A rear passenger pushes up on the front passenger seat with the feet.

reclined too far.

passenger seat are attached to the front passenger seat. Any accessories which might decrease the total seated weight on the front
passenger seat are attached to the front passenger seat.

The front passenger front and side air bags and seat belt pretensioner systems will
deactivate if the total seated weight on the front passenger seat is close to 30 kg (66
lb) and they will reactivate before the weight exceeds 42 kg (93 lb).

Do not increase the total seated weight on the front passenger seat: When an infant or small child sits on the front passenger seat, increasing the total
seated weight on the front passenger seat from the total seated weight of approximately 30 kg (66 lb) is dangerous. The front passenger seat weight sensors
will detect the increased total seated weight, which could result in the unexpected
deployment of the front 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 front passenger seat beyond the total seated weight of approximately
30 kg (66 lb) could result in the front passenger front and side air bags and seat belt
pretensioner system deployment in an accident under the following conditions, for
example:
child-restraint Luggage or other items are placed on the seat with the child in the
child-restraint
system.

lb) and they will reactivate before the weight exceeds 42 kg (93 lb).

CAUTION:

leave heavy luggage on
them.

    the child-restraint If you place your child on the front passenger seat, secure
the child-restraint
system properly and slide the front passenger seat as far back as possible.

NOTE:
- 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 illuminate repeatedly 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 illuminate for 10 seconds if the total
seated weight on the front passenger seat changes.

- If the front passenger air bag deactivation indicator light does not illuminate after installing a child-restraint system on the front passenger seat, install the child-restraint system on the rear
seat and consult an Authorized Mazda Dealer as soon as possible.

Driver and Front 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.
