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/seat belt pretensioner system warning light flashes if the sensor has a possible
malfunction (page 2-45).

Passenger seat weight sensors
Your vehicle is also equipped with the passenger air bag deactivation indicator light. The
deactivation indicator light illuminates when the key is used to turn the passenger air bag
off or the automatic function operates based on the passenger seat weight sensors. These
sensors are located under both of the passenger seat rails. These sensors determine the total
seated weight on 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 total seated
weight is less than approximately 30 kg (66 lb).
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:
lThere is no passenger in the passenger seat. (The passenger air bag deactivation
indicator light does not illuminate.)
lThe total seated weight on the passenger seat is less than approximately 30 kg (66 lb).
(The passenger air bag deactivation indicator light illuminates.)
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 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 2-32.
* If the passenger seat belt is buckled, the passenger air bag deactivation indicator light illuminates, however this does not indicate a malfunction.
If the 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 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 bag using the key (page 2-32) and consult an Authorized Mazda Dealer.
WARNING
Do not decrease the total seated weight on the front passenger seat: When an adult or large child sits on the passenger seat, decreasing the total seated
weight on the passenger seat from the total seated weight of approximately 42 kg
(93 lb) 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 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:
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 total seated weight on the passenger seat is close to 30 kg (66 lb)
and they will reactivate before the weight exceeds 42 kg (93 lb).

NOTElThe 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.
lYou must deactivate the passenger air bag using the key (page 2-32) and consult an Authorized
Mazda Dealer.
Driver and passenger buckle switches
The buckle switches on the seat belts detect whether or not the seat belts are securely
fastened and further control the deployment of the air bags.
qHow the Side Air Bags Workí
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 air bags and after the inflation, the side air bags
quickly deflate. However, the side air bag system for the passenger is designed to only
deploy in accordance with the total seated weight on the passenger seat.
The side air bags will function only once. After that, the side air bags will not work again
and must be replaced. Only an Authorized Mazda Dealer can replace the systems.
The side air bag will deploy only on the
side the vehicle receives the force of the
impact.
qAir Bag Activation/Deactivation
NOTE
If the passenger seat weight sensors detect a total seated weight on the passenger seat is less than
approximately 42 kg (93 lb), the passenger front and side air bags and seat belt pretensioner may not
deploy (page 2-38).
