How the Air Bags Work
qHow 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 system components.
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, all of which provide data from each sensor
to the air bag system.
The front air bags will deploy only
in a frontal or frontal offset impact.
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 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 2-61).

Front passenger seat weight sensors
Your vehicle is also equipped with the front passenger air bag deactivation indicator light
(page 2-39). 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 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:
lThere is no passenger in the front passenger seat. (The front passenger air bag
deactivation indicator light does not illuminate.)
lThe 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.
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.

* 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.
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:
lA rear passenger pushes up on the front passenger seat with the feet.lLuggage 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.
lThe 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 assist grip or the rim of the moonroof and sitting with the seatback reclined too
far.
lAny 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).

WARNING
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:
lLuggage or other items are placed on the seat with the child in the child-restraint
system.
lA rear passenger or luggage push or pull down on the front passenger seatback.lA rear passenger steps on the front passenger seat rails with the feet.lLuggage or other items are placed on the seatback or hung on the head restraint.lThe seat is washed.lLiquids are spilled on the seat.lThe front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
lThe front passenger seatback contacts the rear seat.lLuggage or other items are placed between the front passenger seat and driver seat.lAny accessories which might increase 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).

qHow 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.
The side and curtain air bag will deploy only
on the side the vehicle receives the force of
the impact.
WARNING
Do not place luggage or other objects under the front seats:
Placing luggage or other objects under the front seats is dangerous. The side and
curtain air bag wiring could be damaged, and in the event of a side collision, the side
and curtain air bags may not deploy, which could result in death or serious injury. To
prevent damage to the side and curtain air bag wiring, do not place luggage or other
objects under the front seats.
q Air Bag Activation/Deactivation
NOTE
If the front passenger seat weight sensors detect a total seated weight on the front
