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, which allow for further controlling of the
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 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 2-54).

Front passenger seat weight sensors
Your vehicle is also equipped with the front passenger air bag deactivation indicator light
(page 2-32). 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:
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 air bag deactivation indicator light does not illuminate when 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
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:
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).

lSide impacts with two-wheeled
vehicles may not provide enough force
to deploy the side and curtain air bags.
Non-activation of side and curtain air
bag
The side and curtain air bags will not
normally inflate in the following cases:
lCollision from the rear.
lCollision from the front, but it may
deploy the front air bags.
qConstant Monitoring
The following components of the air bag
systems are monitored by a diagnostic
system:
lSAS unit
lFront air bag sensor
lAir bag modules
lSide crash sensors
lFront seat belt pretensioners
lRelated wiring
lDriver seat slide position sensor
lFront passenger seat weight sensors
lDriver and front passenger seat belt

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.
qAir 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,
constantly 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.
WARNING
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.
qMaintenance
The air bag systems do not require regular
maintenance. But if any of the following
occurs, take your vehicle to an Authorized
Mazda Dealer as soon as possible:
lThe air bag system warning light
flashes.
lThe air bag system warning light
remains illuminated.
lThe air bag system warning light does
not illuminate when the ignition switch
is turned to the ON position.
lThe air bags have deployed.
lFront passenger air bag deactivation
indicator light does not illuminate
when the ignition switch is turned to
the ON position or does not illuminate
as indicated in the chart. For more
details about this indicator light and
this chart, refer to “Front passenger
seat weight sensors ”(page 2-46).
WARNING
Damaged Air Bag/Seat Belt
Pretensioner System Components:
Expended or damaged air bag or seat
belt pretensioner units must be
replaced after any collision which
caused them to deploy or damage
them. Only a trained Authorized
Mazda Dealer can fully evaluate these
systems to see that they will work in
the next accident. Driving with an
expended or damaged air bag or
pretensioner units will provide you
reduced protection in the next accident
and you could be injured or killed.
Removing Interior Parts:
Removing any components such as the
front seats, front dashboard, the
steering wheel or parts on the front
and rear window pillars and along the
roof edge, containing air bag parts or
sensors is dangerous. These parts
contain essential air bag components.
The air bag could accidentally activate
and cause serious injuries. Always
have an Authorized Mazda Dealer
remove these parts.
