SRS Air Bags
If the vehicle receives a strong impact
from the front or side of the vehicle
when the vehicle power is switched
ON, the air bags inflate
instantaneously and lessen the impact
on the head or chest of the driver or
passenger.
The SRS air bag system protects
occupants together with the seat belts
and they are not a substitute for the
seat belts.
There are 5 types of air bags.
Vehicles with the Driver and Front
Passenger Occupant Classification
System have a sensor which detects an
impending roll-over accident.
The air bag supplemental restraint
systems are designed to provide
supplemental protection in certain
situations so seat belts are always
important in the following ways:

Without seat belt usage, the air bags
cannot provide adequate protection
during an accident. Seat belt usage is
necessary to:
Keep the occupant from being
thrown into an inflating air bag.
Reduce the possibility of injuries
during an accident that is not
designed for air bag inflation, such as
roll-over or rear impact.
Reduce the possibility of injuries in
frontal, near frontal or side collisions
or roll-over accidents that are not
severe enough to activate the air
bags.
Reduce the possibility of being
thrown from your vehicle.
Reduce the possibility of injuries to
lower body and legs during an
accident because the air bags
provide no protection to these parts
of the body.
Driver's front air bag
The driver's front air bag is stored in
the center of 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.
The inflation of the driver's dual-stage
air bag is controlled in two energy
stages depending on the driver's seat
position. The driver's seat slide
position sensor is located under the
driver's seat. The sensor determines
whether the driver's seat is forward of
or behind 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's air bag
depending on how close the driver's
seat is to the steering wheel.
During an impact of moderate severity,
the driver's air bag deploys with lesser
energy, whereas during more severe
impacts and when the driver's seat is
behind the reference position, it
deploys with more energy.

Front passenger's front air bag
The front passenger's front air bag is
stored in the dashboard.
Driver and Front Passenger Knee Air
Bags
The knee air bag is stored under the
dashboard.
If the air bag crash sensors receive a
frontal impact of greater than
moderate force, the knee air bags
deploy immediately to reduce impact
to the driver and front passenger's
legs.
Side air bags
There are 2 types of side air bags
including the side air bags for the
driver and front passenger and rear
passengers.
Front seat side air bags
The front seat side air bags are installed
in the outboard sides of the driver and
front passenger's 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.
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.
Rear seat side air bags
The rear seat side air bags are installed
in the outboard sides of the rear
seatbacks. The rear seat side air bags
on the side where the vehicle is hit
deploy regardless of whether or not an
occupant is seated.

Curtain air bags
The curtain air bags are stored in the
front pillars, side edges of the roof, and
the rear pillars. The curtain air bag on
the side where the vehicle is hit
deploys regardless of whether or not
an occupant is seated.
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 driver and front and rear
outboard passengers' heads caused by
directly hitting interior parts such as a
door or window.
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.
In a roll-over:
In response to a vehicle roll-over, both
curtain air bags inflate.
Both curtain air bags will deploy after
the roll-over accident is detected.
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Seat belt pretensionersAir bag/Seat belt pretensioner
system warning light
Related wiringDriver seat slide position sensorFront Passenger occupant classification sensor
Front Passenger occupantclassification module
Front passenger air bag deactivation
indicator light
Front passenger seat belt buckle
switch

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

Warnings and Cautions
for Using the SRS Air Bags
WARNING
Seat belts must be worn in air bag
equipped vehicles.
Depending only on the air bags for
protection during an accident is
dangerous. Alone, air bags may not
prevent serious injuries. The
appropriate air bags can be expected
to inflate only in the first accident, such
as frontal, near frontal or side collisions
or roll-over accidents that are at least
moderate. Vehicle occupants should
always wear seat belts.

Children should not ride in the front
passenger seat.
Placing a child, 12 years or under, in
the front seat is dangerous. The child
could be hit by a deploying air bag and
be seriously injured or even killed. A
sleeping child is more likely to lean
against the door and be hit by the side
air bag in moderate collision to the
front-passenger side of the vehicle.
Whenever possible, always secure a
child 12 years or under on the rear
seats with an appropriate
child-restraint system for the child's
age and size.
Never use a rear-facing child-restraint
system in the front seat with an air
bag that could deploy.
Rear-facing child-restraint systems on
the front seat are particularly
dangerous even though you may feel
assured that a front passenger air bag
will not deploy based on the fact that
the front passenger air bag
deactivation indicator light illuminates.
The child-restraint system can be hit by
a deploying air bag and moved
violently backward resulting in serious
injury or death to the child.
Do not sit too close to the driver and
front passenger air bags.
Sitting too close to the driver and front
passenger air bag modules or placing
hands or feet on them is extremely
dangerous. The driver and front
passenger air bags inflate with great
force and speed. Serious injuries could
occur if someone is too close. The
driver should always hold onto only the
rim of the steering wheel. The front
seat passenger should keep both feet
on the floor. Front seat occupants
should adjust their seats as far back as
possible and always sit upright against
the seatbacks with seat belts worn
properly.

Sit in the center of the seat and wear
seat belts properly.
Sitting too close to the side air bag
modules or placing hands on them, or
sleeping up against the door or
hanging out the windows is extremely
dangerous. The side and curtain air
bags inflate with great force and speed
directly expanding along the door on
the side the car is hit. Serious injury
could occur if someone is sitting too
close to the door or leaning against a
window, or if rear seat occupants grab
the sides of the front seatbacks. Give
the side and curtain air bags room to
work by sitting in the center of the seat
while the vehicle is moving with seat
belts worn properly.
Do not attach objects on or around
the area where air bags deploy.
Attaching objects to the air bags or
placing something in the area where
the air bags deploy is dangerous. In an
accident, an object could interfere with
air bag inflation and injure the
occupants. Furthermore, the bag could
be damaged causing gases to release.
Always keep the deployment area of
the air bag modules free of any
obstructions.
For example, you should not do any of
the following as it may interfere with
air bag deployment.
Do not put a covering on or lean
anything against areas such as the
dashboard and lower portion of the
instrument panel that blocks the
passenger front air bag and knee air
bags.
 Do not use seat covers on the front
seats and rear seats equipped with
in-seat side air bags.
 Do not hang any backpacks, bags or
pouches that cover the sides of the
seats that block the side air bags.Do not place any objects on the
assist grips. Only hang clothes
directly on the coat hooks.
Do not touch the components of the
supplemental restraint system after
the air bags have inflated.
Touching the components of the
supplemental restraint system after the
air bags have inflated is dangerous.
Immediately after inflation, they are
very hot. You could get burned.
Never install any front-end equipment
to your vehicle.
Installation of front-end equipment,
such as frontal protection bar
(kangaroo bar, bull bar, push bar, or
other similar devices), snowplow, or
winches, is dangerous. The air bag
crash sensor system could be affected.
This could cause air bags to inflate
unexpectedly, or it could prevent the
air bags from inflating during an
accident. Front occupants could be
seriously injured.
Do not modify the suspension.
Modifying the vehicle suspension is
dangerous. If the vehicle's height or
the suspension is modified, the vehicle
will be unable to accurately detect a
collision or roll-over accident resulting
in incorrect or unexpected air bag
deployment and the possibility of
serious injuries.
To prevent false detection by the air
bag sensor system, heed the
following.
 Do not use tires or wheels other than
those
specified for your Mazda:

Use of any tire or wheel other than
those specified for your Mazda (page
10-71) is dangerous. Use of such
wheels will prevent the vehicle's
accident detections system from
accurately detecting a collision or
roll-over accident resulting in
incorrect or unexpected air bag
deployment and the possibility of
serious injuries.
 Do not overload your vehicle:
Overloading your vehicle is
dangerous as it could prevent the air
bag crash sensor system from
accurately detecting a collision or
roll-over accident resulting in
incorrect or unexpected air bag
deployment and the possibility of
serious injuries. The gross axle
weight rating (GAWR) and the gross
vehicle weight rating (GVWR) for
your vehicle are on the Motor
Vehicle Safety Standard Label on the
driver's door fram e. Do not exceed
these ratings.
Do not modify a front door or leave
any damage unrepaired. Always have
an Authorized Mazda Dealer inspect a
damaged front door.
Modifying a front door or leaving any
damage unrepaired is dangerous. Each
front door has a side crash sensor as a
component of the supplemental
restraint system. If holes are drilled in a
front door, a door speaker is left
removed, or a damaged door is left
unrepaired, the sensor could be
adversely affected causing it to not
detect the pressure of an impact
correctly during a si de collision. If a
sensor does not detect a side impact
correctly, the side and curtain air bags
and the front seat belt pretensioner
may not operate norm ally which could
result in serious injury to occupants.Do not modify the supplemental
restraint system.
Modifying the components or wiring of
the supplemental restraint system is
dangerous. You could accidentally
activate it or make it inoperable. Do
not make any modifications to the
supplemental restraint system. This
includes installing trim, badges, or
anything else over the air bag modules.
It also includes installing extra
electrical equipment on or near system
components or wiring. An Authorized
Mazda Dealer can provide the special
care needed in the removal and
installation of front seats and rear seats
equipped with in-seat side air bags. It
is important to protect the air bag
wiring and connecti ons to assure that
the bags do not accidentally deploy,
and that the front passenger occupant
classification system and the seats
retain an undamaged air bag
connection.
Do not place luggage or other objects
under the front seats and rear seats.
Placing luggage or other objects under
the front or rear seats equipped with
in-seat side air bags 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
afford 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.
