How the Front Air Bags Work
When air bag crash sensors detect a frontal impact of greater than moderate force, an
electrical current is sent to the inflators.
Gases are produced to inflate the front air bags and after the inflation, the front air bags
quickly deflate.
The front air bags will function only once. After that, the front air bags will not work
again and must be replaced.

Only an Authorized Mazda Dealer can replace the systems.
The front, dual stage air bags control air bag inflation in two energy stages. During an
impact of moderate severity the front air bags deploy with lesser energy, whereas during
more severe impacts, they deploy with more energy. Deployment of the front air bags may
differ between the driver and the front passenger depending on the driver seat position,
front passenger weight and front seat belt usage, which allow for further controlling of the
system.
Driver seat slide position sensor
Your vehicle is equipped with a driver seat slide 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 crash
sensors and diagnostic module (SAS unit). The sensor is also 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 2-53).
How the Air Bags Work
The front air bags will deploy only
in a frontal or frontal offset impact.

Front passenger seat weight sensors
If your vehicle is equipped with front passenger seat weight sensors, a front passenger air
bag deactivation indicator light is also equipped (page 2-29). 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 sensors are also designed to prevent the front passenger
front and side air bags and seat belt pretensioner system from inflating 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 chart below.
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.
Front passenger air bag deactivation indicator light
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. After about 6 seconds 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 deactivation
indicator light illuminates, however this does not indicate a malfunction.
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.

Decreasing 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:
•A rear passenger pushes up on the front passenger seat with the feet.
•Luggage or other items placed under the front passenger seat or between the front
passenger seat and driver seat that push up the front passenger seat bottom.
•The front passenger seat occupant sits in a manner that does not place the entire
weight of the occupant on the seat such as by sitting too close to the door, grasping
the rim of the moonroof.
•The front passenger seatback contacts the rear seat.
•Any accessories which might decrease the total seated weight on the front
passenger seat are attached to the front passenger seat.

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 on the front seats.

How the Side and Curtain Air Bags Work*
When air bag crash sensors detect a side impact of greater than moderate force, an
electrical current is sent to the inflators.
Gases are produced to inflate the side and curtain air bags and after the inflation, the side
and curtain air bags quickly deflate.
The side and curtain air bags will function only once. After that, the side and curtain air
bags will not work again and must be replaced.
Only an Authorized Mazda Dealer can
replace the systems.
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.
To prevent damage to the side and curtain air bag wiring, don’t place luggage or other
objects under the front seats.
The side air bag will deploy only on the side
the vehicle receives the force of the impact.The curtain air bag will deploy only on the side
the vehicle receives the force of the impact.

Constant Monitoring
The following components of the air bag
systems are monitored by a diagnostic
system:
•SAS unit
•Front air bag sensor
•Air bag modules
•Side crash sensor
*
•Front seat belt pretensioners
•Related wiring
•Driver seat slide position sensor
•Front passenger seat weight sensors
•Driver and front passenger seat belt
buckle switches
The diagnostic module continuously
monitors the system’s readiness. This
begins when the ignition switch is turned
to the ON position and continues while
the vehicle is being driven.

Air Bag/Front Seat Belt
Pretensioner System Warning
Light
If the air bag/front seat belt pretensioner
system is normal, the warning light
illuminates when the ignition switch is
turned to the ON position or after the
engine is cranked. After about 6 seconds it
goes out.
A system malfunction is indicated when
the warning light constantly flashes,
illuminates or doesn’t illuminate at all
when the ignition switch is turned to the
ON position. If any of these occur, consult
an Authorized Mazda Dealer as soon as
possible. The system may not work in an
accident.
Self-Servicing the Air Bag/
Pretensioner Systems:
Self-servicing or tampering with the
systems is dangerous. An air bag/
pretensioner could accidentally
activate or become disabled. This
could cause serious injuries. Never
tamper with the systems and always
have an Authorized Mazda Dealer
perform all servicing and repairs.
