Do not place luggage or other objects under the front seats:
Placing luggage or other objects under the front seats is dangerous. The components
essential to the supplemental restraint system could be damaged, and in the event of
a side collision, the appropriate air bags may not deploy, which could result in death
or serious injury. To prevent damage to the components essential to the supplemental
restraint system, do not place luggage or other objects under the front seats.
Do not operate a vehicle with damaged air bag/seat belt pretensioner system
components:
Expended or damaged air bag/seat belt pretensioner system components must be
replaced after any collision which caused them to deploy or damage them. Only a trained
Authorized Mazda Dealer can fully evaluate these systems to see that they will work in
any subsequent accident. Driving with an expended or damaged air bag or pretensioner
unit will not aff ord you the necessary protection in the event of any subsequent accident
which could result in serious injury or death.
Do not remove interior air bag parts:
Removing any components such as the front seats, front dashboard, the steering wheel
or parts on the front and rear window pillars and along the roof edge, containing air bag
parts or sensors is dangerous. These parts contain essential air bag components. The air
bag could accidentally activate and cause serious injuries. Always have an Authorized
Mazda Dealer remove these parts.
Properly dispose of the air bag system:
Improper disposal of an air bag or a vehicle with live air bags in it can be extremely
dangerous. Unless all safety procedures are followed, injury could result. Have an
Authorized Mazda Dealer safely dispose of the air bag system or scrap an air bag
equipped vehicle.

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 in À 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 in À 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.

Front Passenger Air Bag
The front passenger air bag is mounted in the front passenger dashboard.
The in À 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 ).

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 in À ates the side air bag only on the side in which the vehicle was hit. The side
air bag in À 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 ).

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

Front Passenger Occupant Classi ¿ cation System
First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-38 )
carefully.
Front Passenger Occupant Classi ¿ cation Sensor
Your vehicle is equipped with a front passenger occupant classi ¿ cation sensor as a part
of the supplemental restraint system. This sensor is equipped in the front passenger's seat
cushion. This sensor measures the electrostatic capacity of the front passenger's seat. The
SAS unit is designed to prevent the front passenger front and side air bags and seat belt
pretensioner system from deploying if the front passenger air bag deactivation indicator
light turns on.
To reduce the chance of injuries caused by deployment of the front passenger air bag,
the system deactivates the front passenger front and side air bags and also the seat belt
pretensioner system when the front passenger air bag deactivation indicator light turns
on. Refer to the following table for the front passenger air bag deactivation indicator light
illumination conditions.
This system shuts off the front passenger front and side air bags and seat belt pretensioner
system, so make sure the front passenger air bag deactivation indicator light turns on
according to the following table.
The air bag/front seat belt pretensioner system warning light À ashes and the front passenger
air bag deactivation indicator light illuminates if the sensors have a possible malfunction.
If this happens, the front passenger front and side air bags and seat belt pretensioner system
will not deploy.
Front passenger air bag deactivation indicator light
This indicator light turns on to remind you that the front passenger front and side air bags
and seat belt pretensioner will not deploy during a collision.
