Hot Air Bag Inflators:
Hot air bag inflators are dangerous. Immediately after inflation, the inflators in the
steering wheel, dashboard, seatbacks, or the front and rear window pillars and along
the roof edge are very hot. You could get burned. Don’t touch the internal components
of the air bag storage areas after the bags have inflated.
Installation of Front-End Equipment:
Installation of front-end equipment, such as frontal protection bar (kangaroo bar,
bull bar, push bar, etc.), 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. Never install any front-end equipment to your vehicle.
Suspension Adjustment:
Adjusting the vehicle suspension is dangerous. If the vehicle’s height or the
suspension is changed, the vehicle will be unable to accurately detect a collision
resulting in incorrect or unexpected air bag deployment and the possibility of serious
injuries.
Modification of 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. Don’t make any
modifications to the supplemental restraint system. This includes installing trim,
badges, or anything else over the air bag storage areas. It also includes installing
extra electric 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. It is important to protect the side and curtain air bag wiring and
connections to assure that the bags do not accidentally deploy and that the seats retain
an undamaged air bag connection.
To prevent damage to the side and curtain air bag wiring, don’t place luggage or other
objects under the front seats.

NOTE
•When an air bag deploys, a loud inflation noise can be heard and some smoke will be
released. Neither is likely to cause injury, however, the texture of the air bags may
cause light skin injuries on body parts not covered with clothing through friction.
•Should you sell your Mazda, we urge you to tell the new owner of its air bag systems
and that familiarization with all instructions about them, from the Owner’s Manual, is
important.

The supplemental restraint systems (SRS) have two basic subsystems:
•The air bag system with inflators and air bags.
•The electric system with crash sensors and diagnostic module.
The air bags are mounted in the following locations: the center of the steering wheel, the
passenger-side of the dashboard, in the outboard sides of the front seatbacks and the front
and rear window pillars, along the roof edge. They are out of sight until activated.
*1The driver’s seat slide position sensor determines whether the driver’s seat is fore or aft
of a reference position. The sensor 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.
*2The buckle switches on the front seat belts determine whether or not the front seat belts
are securely fastened and further control the deployment of the air bags on the front
seats.
*3The front, dual stage air bags control air bag inflation in two energy stages. During an
impact of moderate severity the front air bags deploy with lesser energy, whereas during
more severe impacts, they deploy with more energy.
Deployment of the front air bags may differ between the driver and the front passenger
depending on the driver’s seat position and front seat belt usage, which allow for further
controlling of the system.

How the Air Bags Work
When air bag crash sensors detect a frontal or side impact of greater than moderate force,
an electrical current is sent to the inflators.
Gases are produced to inflate the air bags and after the inflation, the air bags quickly
deflate.
The air bags will function only once. After that, the air bags will not work again and
must be replaced.

Only an Authorized Mazda Dealer can replace the systems.
The side air bag will deploy only on the side
the vehicle receives the force of the impact.
The curtain air bag will deploy only on the side
the vehicle receives the force of the impact.
The front air bags will deploy
only on the frontal impact.
The side and curtain air bags will deploy together
on the same side.

Air Bag Activation/Deactivation
Front air bag activation
A greater than moderate impact will cause the front air bags to inflate in the following
cases:
Hitting a solid wall straight on at greater
than about 22 km/h (14 mph).Frontal impact within about a 30 degree
range from head-on to the vehicle.
Driving into a big hole or hitting the far
side of a hole. Hitting a curb, pavement edge or hard
object.
Landing hard or the vehicle falling.

Limitations to front air bag activation
Depending on the severity of impact, the front air bags may not inflate in the following
cases:
Non-activation of front air bags
Front air bags will not normally inflate in the following cases:
Impacts involving trees or poles cause severe
cosmetic damage but may not have enough
impact to activate the air bag.Rear-ending or running under a truck's tail
gate may not provide the stopping force
necessary for air bag deployment.
Frontal offset impact to the vehicle may not
provide the stopping force necessary for air
bag deployment.
Collision from the rear.
Impact to the side, but it may deploy the side
and curtain air bags.Vehicle roll-over, may deploy the side and
curtain air bags but not the front air bags.

Side and curtain air bag activation
Greater than moderate impact to one side of the vehicle (driver or passenger side areas) will
cause the side and curtain air bags to inflate, but it will not normally deploy the front air
bags.
Limitations to side and curtain air bag activation
Depending on the severity of impact, the side and curtain air bags may not inflate in the
following cases:
Side impacts involving trees or poles can
cause severe cosmetic damage but may not
have enough impact force to activate the
side and curtain air bags.Side impacts with two-wheeled vehicles
may not provide enough force to deploy the
side and curtain air bags. Vehicle roll-over may not provide enough
side force to deploy the side and curtain
air bags. Frontal offset impact may not provide
enough side impact to deploy the side and
curtain air bags.

Constant Monitoring
The following components of the air bag
systems are monitored by a diagnostic
system:
•SAS unit
•Front air bag sensor
•Air bag modules
•Side and curtain air bag crash sensor
•Front seat belt pretensioners
•Related wiring
•Driver’s seat slide position sensor
•Front seat belt buckle switches
A diagnostic module continuously
monitors the systems’ readiness. This
begins when the ignition switch is turned
to the ON position and continues while
the vehicle is being driven.

Air Bag/Front Seat Belt
Pretensioner System Warning
Light
If the air bag/front seat belt pretensioner
system is OK, the warning light comes on
when the ignition switch is turned to the
ON position or after the engine is cranked.
After about 6 seconds it goes out.A system malfunction is indicated when
the warning light constantly flashes, stays
on or doesn’t come on at all when the
ignition switch is turned to the ON
position. If any of these occur, consult an
Authorized Mazda Dealer as soon as
possible. The system may not work in an
accident.

Maintenance
The air bag systems do not require regular
maintenance. But if any of the following
occurs, take your vehicle to an Authorized
Mazda Dealer as soon as possible:
•The air bag system warning light
flashes.
•The air bag system warning light stays
on.
•The air bag system warning light stays
off when the ignition switch is turned
to the ON position.
•The air bags inflate.
Self-Servicing the Air Bag/
Pretensioner Systems:
Self-servicing or tampering with the
systems is dangerous. An air bag/
pretensioner could accidentally
activate or become disabled. This
could cause serious injuries. Never
tamper with the systems and always
have an Authorized Mazda Dealer
perform all servicing and repairs.

Damaged Air Bag Sensors:
Driving with damaged air bag sensors
is dangerous. A collision, even one
not strong enough to inflate the air
bags, could damage the sensors. If
there was a subsequent collision, a
damaged sensor would not inflate the
air bags. Always have an Authorized
Mazda Dealer inspect the air bag
systems after a collision.
Removing Interior Parts:
Removing any components such as
the front seat, 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 parts. The
air bag could accidentally activate
and cause serious injuries. Always
have an Authorized Mazda Dealer
remove these parts.
Air Bag Disposal:
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
can result. Ask an Authorized Mazda
Dealer how to safely dispose of an air
bag or how to scrap an air bag
equipped vehicle.
