How the SRS Air Bags Work
Your Mazda is equipped with the following types of SRS air bags. SRS air bags are
designed to work together with the seat belts to help to reduce injuries during an accident.
The SRS air bags are designed to provide further protection for passengers in addition to the
seat belt functions. Be sure to wear seat belts properly.
Seat Belt Pretensioners
The front seat belt pretensioners are designed to deploy in moderate or severe frontal, near
frontal collisions.
In addition, the pretensioners operate when a side collision (only on the side in which the
collision occurs) or a roll-over accident is detected. The pretensioners operate differently
depending on what types of air bags are equipped. For more details about seat belt
pretensioner operation, refer to the SRS Air Bag Deployment Criteria (page 2-51 ).
Driver Air Bag
The driver's air bag is mounted in the steering wheel.
When air bag crash sensors detect a frontal impact of greater than moderate force, the
driver's air bag inÀ ates quickly helping to reduce injury mainly to the driver's head or chest
caused by directly hitting the steering wheel.
For more details about air bag deployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-51 ).
(With Front Passenger Occupant Classi¿ cation System)
The driver's dual-stage air bag controls air bag inÀ ation in two energy stages. During an
impact of moderate severity, the driver's air bag deploys with lesser energy, whereas during
more severe impacts, it deploys with more energy.

SRS Air Bags
Front Passenger Air Bag
The front passenger air bag is mounted in the front passenger dashboard.
The inÀ ation mechanism for the front passenger air bag is the same as the driver's air bag.
For more details about air bag deployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-51 ).
(With Front Passenger Occupant Classi¿ cation System)
In addition, the front passenger air bag is designed to only deploy when the front passenger
occupant classi¿ cation sensor detects a passenger sitting on the front passenger's seat. For
details, refer to the front passenger occupant classi¿ cation system (page 2-55 ).

SRS Air Bags
*Some models.
Side Air Bags *
The side air bags are mounted in the outboard sides of the front seatbacks.
When the air bag crash sensors detect a side impact of greater than moderate force, the
system inÀ ates the side air bag only on the side in which the vehicle was hit. The side
air bag inÀ ates quickly to reduce injury to the driver or front passenger's chest caused by
directly hitting interior parts such as a door or window.
For more details about air bag deployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-51 ).
(With Front Passenger Occupant Classi¿ cation System)
In addition, the front passenger side bag is designed to only deploy when the front passenger
occupant classi¿ cation sensor detects a passenger sitting on the front passenger's seat. For
details, refer to the front passenger occupant classi¿ cation system (page 2-55 ).

*Some models.
Curtain Air Bags *
The curtain air bags are mounted in the front and rear window pillars, and the roof edge
along both sides.
When the air bag crash sensors detect a side impact of greater than moderate force, the
curtain air bag inÀ ates quickly and helps to reduce injury mainly to the rear outboard
passenger's head caused by directly hitting interior parts such as a door or window.
For more details about air bag deployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-51 ).
In a side impact:
Greater than moderate impact to one side of the vehicle will cause the curtain air bag on that
side only to inÀ ate.


Only one side curtain air bag will deploy on the
side of the vehicle that receives the force of an
impact.

(With Front Passenger Occupant Classi¿ cation System)
In a roll-over:
In response to a vehicle roll-over, both curtain air bags inÀ ate.


Both curtain air bags will deploy after
the roll-over accident is detected.

Warning Light/Beep
A system malfunction or operation conditions are indicated by a warning.
Refer to Warning/Indicator Lights on page 4-24 .
Refer to Warning Sound is Activated on page 7-39 .

The front passenger front and side air bags and the seat belt pretensioner are designed to deploy when the front
passenger occupant classi¿ cation sensor detects a passenger sitting on the front passenger's seat.

In a side collision, the seat belt pretensioners and the side/curtain air bags deploy (only on the side in which the
collision occurs).
*3 (With Front Passenger Occupant Classi¿ cation System)
In a roll-over accident, the seat belt pretensioners and the curtain air bags deploy.

In a frontal offset collision, the equipped air bags and pretensioners may all deploy
depending on the direction, angle, and rate of impact.
