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.
▼ Front Seat Belt Pretensioners
The front seat belt pretensioners are designed to deploy in mod
erate or severe frontal, near
frontal collisions.
In addition, the pretensioners ope rate 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 deta ils about seat belt
pretensioner operation, refer to the SRS Air Bag Deployment Cri teria (page 2-58).
▼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 Ba g Deployment Criteria"
(page 2-58).
(With Front Passenger Occupa nt Classification System)
The driver's dual-stage air bag controls air bag inflation 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.

▼Front Passenger Air Bag
The front passenger air bag is mounted in the front passenger d
ashboard.
The inflation mechanism for the front passenger air bag is the same as the driver's air bag.
For more details about air bag de ployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-58).
(With Front Passenger Occupa nt Classification System)
In addition, the front passenger air bag is designed to only de ploy when the front passenger
occupant classification sensor detects a passenger sitting on t he front passenger's seat. For
details, refer to the front passenger occupant classification s ystem (page 2-61).

▼Side Air Bags*
The side air bags are mounted in the outboard sides of the fron
t seatbacks.
When the air bag crash sensors detect a s ide impact of greater than moderate force, the
system inflates the side air bag only on the side in which the vehicle was hit. The side air
bag inflates quickly to reduce i njury 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 Ba g Deployment Criteria"
(page 2-58).
(With Front Passenger Occupa nt Classification System)
In addition, the front passenger side bag is designed to only d eploy when the front passenger
occupant classification sensor detects a passenger sitting on t he front passenger's seat. For
details, refer to the front passenger occupant classification s ystem (page 2-61).

▼Curtain Air Bags*
The curtain air bags are mounted in the front and rear window p
illars, 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 mai nly to the rear outboard
passenger's head caused by dir ectly hitting interior parts such as a door or window.
For more details about air bag de ployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-58).
In a side impact:
Greater than moderate impact to o ne side of the vehicle will cause the curtain air bag on that
side only to inflate.

Only one side curtain air bag will deploy on the
side of the vehicle that receives the force of an
impact.
(With Front Passenger Occupa nt Classification System)
In a roll-over:
In response to a vehicle roll-ov er, both curtain air bags inflate.

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

In an angled collision:
During a collision, the driver and front passenger's air bags will deploy. Depending on the
nature of the impact, t he side air bag and the curtain air bag may deploy.

A system malfunction or operation conditions are indicated by a
warning.
