First, please read "Supplemental
Restraint System (SRS) Precautions"
(page 2-52) 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 (page 2-62).

▼Front Passenger Seat Weight
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 and
monitor the seat belt buckle for the
front passenger seat. The SAS unit is
designed to prevent the front
passenger front and side air bags and
knee air bags, and seat belt
pretensioner system from deploying if
the front passenger air bag
deactivation indicator light illuminates.
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 knee air bags,
and also the seat belt pretensioner
system when the front passenger air
bag deactivation indicator light
illuminates. 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
knee 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
knee air bags, and seat belt
pretensioner system will not deploy.
Front passenger air bag deactivation
indicator light
This indicator light illuminates to
remind you that the front passenger
front and side air bags and knee air
bags, and seat belt pretensioners will
not deploy during a collision.

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
illuminate when the ignition is
switched ON and does not illuminate
as indicated in the front passenger air
bag deactivation indicator light on/off
condition 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 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 knee air bags,
and the 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
could result in an air bag not deploying
under the following conditions, for
example:

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 is dangerous. The front
passenger seat we ight 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
knee 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 could result in the front
passenger front and side air bags and
knee air bags, and seat belt
pretensioner system deployment in an
accident under the following
conditions, for example:
 Luggage or other items are placed on
the seat with the child in the
child-restraint system.
