SRS Air Bags

How the SRS Air Bags Work

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.

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 inflates 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" (Search).

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 inflate.

 

(With Front Passenger Occupant Classification System)

In a roll-over:

In response to a vehicle roll-over, both curtain air bags inflate.

 

SRS Air Bag Deployment Criteria

SRS Air Bag Deployment Criteria

This chart indicates the applicable SRS equipment that will deploy depending on the type of collision.

(The illustrations are the representative cases of collisions.)

X: The SRS air bag equipment is designed to deploy in a collision.

  1. (With Front Passenger Occupant Classification System)

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

  2. In a side collision, the seat belt pretensioners and the side/curtain air bags deploy.

  3. (With Front Passenger Occupant Classification 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.

Constant Monitoring

Constant Monitoring

The following components of the air bag systems are monitored by a diagnostic system:

 

  • Front air bag sensors

  • Crash sensors, and diagnostic module (SAS unit)

  • Side crash sensors

  • Air bag modules

  • Front seat belt pretensioners

  • Air bag/Front seat belt pretensioner system warning light

  • Related wiring

(With Front Passenger Occupant Classification System)

  • Front passenger occupant classification sensor

  • Front passenger occupant classification module

  • Front passenger air bag deactivation indicator light

 

The diagnostic module continuously monitors the system's readiness. This begins when the ignition is switched ON and continues while the vehicle is being driven.
