How the SRS Air BagsWo r k
▼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 Bel
t 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 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 2-68).
▼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 2-68).
(With Front Passenger Occupant
Classification System)
The driver's dual-stag e 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.

(With Front Passenger Occupa nt Classification System)
The front passenger front and si de air bags, seat belt pretensioner and knee air bag are designed to deploy
depending on the condition of the total seated weight on the front passenger seat.
*2 (With Front Passenger Occupa nt Classification System)
In a roll-over accident, the seat belt pretensioners and the cu rtain air bags deploy.
NOTE
In a frontal offset collision, the equipped air bags and pretensioners may all deploy
depending on the direction, angle, and rate of impact.

Limitations to roll-over detection (With
Front Passenger Occupant
Classification System):
The following illustration is an example of
an accident that may not be detected as a
roll-over accident. Therefore, the front
seat belt pretensioners and curtain air bags
may not deploy.

First, please read "Supplemental Restraint
System (SRS) Precau
tions" (page 2-55)
carefully.
▼ Driver Seat Slide Position Sensor
Your vehicle is equipped with a driver seat
slide position sensor as a part of the
supplemental restrain
t 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 2-67).

▼Front 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
knee 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 fr ont passenger air bag,
the system deactivates the front passenger
front and side air bags and knee 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 knee 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
knee air bags, and seat belt pretensioner
system will not deploy.
Front passenger air bag deactivation
indicator light
This indicator light illuminates to remind
you that the front passenger front and side
air bags and knee air bags, and seat belt
pretensioners will not deploy during a
collision.
If the front passenger weight sensors are
normal, the indicator light illuminates
when the ignition is switched ON. The
light turns off after a few seconds. Then,
the indicator light illuminates or is off
under the following conditions:

The curtain air bag is ready for inflating regardless of
what the front passenger air bag deactivation

If the front passenger air bag deactivation
indicator light does not illuminate when
the ignition is switched ON and does not
illuminate as indicated in the front

light on/off condition chart, do not allow a
child to sit in the front passenger seat and
consult an Authorized Mazda Dealer as
soon as possible. The system may not
work properly in an accident.
WA R N I N G
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 de tect the reduced total
seated weight condition and the front
passenger front and side air bags and knee
air bags, and the 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:

A front passenger is seated as shown in
the following figure:A rear passenger pushes up on the front
passenger seat with their feet.
 Luggage 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.
 Any 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 knee air bags, and the seat belt
pretensioner system will deactivate if the
front passenger air bag deactivation
indicator light illuminates.

Do not increase the total seated weight on
the front passenger seat:
When an infant or small child sits on the
front passenger seat, increasing the total
seated weight on th e front passenger seat
is dangerous. The front passenger seat
weight sensors will detect the increased
total seated weight, which could result in
the unexpected deployment of the front
passenger front and side air bags and knee
air bags, and seat belt pretensioner system
in an accident and may cause serious
injury. Increasing the total seated weight
on the front passenger seat could result in
the front passenger front and side air bags
and knee air bags, and seat belt
pretensioner system deployment in an
accident under the following conditions,
for example:
 Luggage or other items are placed on the
seat with the child in the child-restraint
system.
 A rear passenger or luggage push or pull
down on the front passenger seatback.
