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.
qFront Seat Belt Pretensioners
The front seat belt pretensioners are designed to deploy in moderate or severe frontal, near
frontal collisions or roll-over accidents.
qDriver 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 2-63).
(With Driver and Front Passenger Occupant 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.
qFront Passenger Air Bag
The front passenger air bag is mounted in the front passenger dashboard. The inflation
mechanism for the front passenger air bag is the same as the driver's air bag, as mentioned
above.
For more details about air bag deployment, refer to“SRS Air Bag Deployment Criteria”
(page 2-63).

(With Driver and Front Passenger Occupant Classification System)
In addition, the front passenger air bag is designed to only deploy in accordance with the
total seated weight on the front passenger seat. For details, refer to the driver and front
passenger occupant classification system (page 2-66).
qSide 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 inflates the side air bag only on the side in which the vehicle was hit. The side air
bag inflates 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 2-63).
(With Driver and Front Passenger Occupant Classification System)
In addition, the front passenger side air bag is designed to only deploy in accordance with
the total seated weight on the front passenger seat. For details, refer to the driver and front
passenger occupant classification system (page 2-66).
A side air bag will deploy only on the side the
vehicle receives the force of the impact.

qCurtain 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”
(page 2-63).
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.
A curtain air bag will deploy only on the side the
vehicle receives the force of the impact.
In a roll-over:
In response to a vehicle roll-over, both curtain air bags inflate.
Both curtain air bags will deploy after
a roll-over accident is detected.

qAir Bag/Front Seat Belt Pretensioner System Warning Light
If the air bag/front seat belt pretensioner system is working properly, the warning light
illuminates when the ignition is switched ON or after the engine is cranked. The warning
light turns off after a specified period of time.
A system malfunction is indicated if the warning light constantly flashes, constantly
illuminates or does not illuminate at all when the ignition is switched ON. If any of these
occur, consult an Authorized Mazda Dealer as soon as possible. The system may not work
in an accident.
WARNING
Never tamper with the air bag/pretensioner systems and always have an Authorized
Mazda Dealer perform all servicing and repairs:
Self-servicing or tampering with the systems is dangerous. An air bag/pretensioner
could accidentally activate or become disabled causing serious injury or death.
qAir Bag/Front Seat Belt Pretensioner System Warning Beep
If a malfunction is detected in the air bag/front seat belt pretensioner systems and the
warning light, a warning beep sound will be heard for about 5 seconds every minute.
The air bag and seat belt pretensioner system warning beep sound will continue to be heard
for approximately 35 minutes.
Have your vehicle inspected at an Authorized Mazda Dealer as soon as possible.
WARNING
Do not drive the vehicle with the air bag/front seat belt pretensioner system warning
beep sounding:
Driving the vehicle with the air bag/front seat belt pretensioner system warning beep
sounding is dangerous. In a collision, the air bags and the front seat belt
pretensioner system will not deploy and this could result in death or serious injury.
Contact an Authorized Mazda Dealer to have the vehicle inspected as soon as
possible.

Driver and Front Passenger Occupant Classification Systemí
First, please read“Supplemental Restraint System (SRS) Precautions”(page 2-53)
carefully.
NOTE
This system is equipped on models for the U.S., Canadian and Puerto Rican markets.
qDriver Seat Slide Position Sensor
Your vehicle is equipped with a driver seat slide position sensor as a part of the
supplemental restraint system. The sensor is located under the driver seat. The sensor
determines whether the driver seat is fore or aft of 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 air bag depending on how close the driver seat is to the steering
wheel.
The air bag/front seat belt pretensioner system warning light flashes if the sensor has a
possible malfunction (page 2-62).
qFront Passenger Seat Weight Sensors
Your vehicle is equipped with a front passenger seat weight sensors as a part of the
supplemental restraint system. These sensors are located under both of the front passenger
seat rails. These sensors determine the total seated weight on the front passenger seat and
monitor the seat belt buckle for the front passenger 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 illuminates.
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
illuminates.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 illuminates
according to the following table.
The air bag/front seat belt pretensioner system warning light flashes 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.

WARNING
Do not decrease the total seated weight on the front passenger seat:
When an adult or large child sits on the front passenger seat, decreasing the total
seated weight on the front passenger seat required for air bag deployment is
dangerous. The front passenger seat weight sensors will detect the reduced total
seated weight condition and the front passenger front and side air bags and seat
belt pretensioner system will not deploy during an accident. The front passenger will
not have the supplementary protection of the air bag, which could result in serious
injury. Decreasing the total seated weight on the front passenger seat could result in
an air bag not deploying under the following conditions, for example:
ØA rear passenger pushes up on the front passenger seat with their feet.
ØLuggage or other items placed under the front passenger seat or between the
front passenger seat and driver seat that push up the front passenger seat
bottom.
ØThe front passenger seat occupant sits in a manner that does not place the entire
weight of the occupant on the seat such as by sitting too close to the door,
grasping the assist grip or the rim of the moonroof and sitting with the seatback
reclined too far.
ØAny accessories which might decrease the total seated weight on the front
passenger seat are attached to the front passenger seat.
The front passenger front and side air bags and seat belt pretensioner systems will
deactivate if the front passenger air bag deactivation indicator light illuminates.
