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 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 2-57).
Front
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 or a roll-over
accident (with roll-over sensor) is
detected.
Rear Outboard
*
The rear outboard seat belt
pretensioners are designed to deploy
in moderate or severe frontal, near
frontal collisions.

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
inflates 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 2-57).
(With Front Passenger Air Bag
Deactivation Switch)
The inflation of the driver's dual-stage
air bag is controlled in two energy
stages depending on the driver's seat
position. The driver's seat slide
position sensor is located under the
driver's seat. The sensor determines
whether the driver's seat is forward of
or behind a reference position and
sends the seat position to the
diagnostic module (SAS unit). The SAS
unit is designed to control the
deployment of the driver's air bag
depending on how close the driver's
seat is to the steering wheel.
During an impact of moderate severity,
the driver's air bag deploys with lesser
energy, whereas during more severe
impacts and when the driver's seat is
behind the reference position, it
deploys with more energy.

in the front passenger instrument
panel.
