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 2-62).
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 2-62).
(With Front Passenger Occupant Classification System)
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.
