Essential Safety Equipment
SRS Air Bags
Form No. 8S18-EA-03I
Small children should be protected by a child-restraint system. In certain regions, larger
children must use a child-restraint system (page 2-21).
Carefully consider which child-restraint system is necessary for your child and follow the
installation directions in this Owner’s Manual as well as the child-restraint system
manufacturer’s instructions.
Air Bags without Seat Belts:
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 collisions with frontal, near frontal or side forces that are at
least moderate. Vehicle occupants should always wear seat belts.
Child in the Front 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. Even if the front
passenger air bag deactivation indicator light illuminates, always move the front
passenger seat as far back as possible. A sleeping child is more likely to lean against
the door and be hit by the side air bag in a moderate, right-side collision. Whenever
possible, always secure a child 12 years and under on the rear seat with an
appropriate child-restraint system for the child’s age and size.
Rear-Facing Child-Restraint System:
Rear-facing child-restraint systems on the front seat are particularly dangerous.
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. Even though you may feel
assured that the front passenger air bag will not deploy based on the fact that the front
passenger air bag deactivation indicator light illuminates, NEVER use a rear-facing
child-restraint system in the front seat with an air bag that could deploy even in a
moderate collision.

Seating Position with Front Air Bags:
Sitting too close to the air bag modules or placing hands or feet on them is extremely
dangerous. Front 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.
Seating Position with Side and Curtain Air Bags:
Sitting too close to the side air bag modules or placing hands on them is extremely
dangerous. The side air bags inflate with great force and speed directly out of the
outboard side of the front seat and expand along the front 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.
Furthermore, sleeping up against the door or hanging out the windows in the vehicle
could block the side and curtain air bags and eliminate the advantages of
supplemental protection. 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.
Front Air Bag Modules:
Attaching an object to the front air bag modules or placing something in front of them
is dangerous. In an accident, the object could interfere with front air bag inflation
and injure the occupants.
Always keep the front air bag modules free of objects.
Side Air Bag Modules:
Attaching things to the front seat in such a way as to cover the outboard side of the
seat in any way is dangerous. In an accident the object could interfere with the side
air bag, which inflates from the outboard side of the front seats, impeding the added
protection of the side air bag system or redirecting the air bag in a way that is
dangerous. Furthermore, the bag could be cut open spewing exhaust.
Do not hang net bags, map pouches or backpacks with side straps on the front seats.
Never use seat covers on the front seats. Always keep the side air bag modules in your
front seats free to deploy in the event of a side collision.

Curtain Air Bag Modules:
Attaching objects to the areas where the curtain air bag activates such as on the
windshield glass, side door glass, front and rear window pillars and along the roof
edge and assist grips is dangerous. In an accident the object could interfere with the
curtain air bag, which inflates from the front and rear window pillars and along the
roof edge, impeding the added protection of the curtain air bag system or redirecting
the air bag in a way that is dangerous. Furthermore, the bag could be cut open
spewing exhaust.
Do not place hangers or any other objects on the assist grips. When hanging clothes,
hang them on the coat hook directly. Always keep the curtain air bag modules free to
deploy in the event of a side collision.
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 modules 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 modules. 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 air bag wiring and connections to assure that the
bags do not accidentally deploy, the driver seat slide position sensor and front
passenger seat weight sensors are not damaged and that the seats retain an
undamaged air bag connection.
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.

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

Only an Authorized Mazda Dealer can replace the systems.
The 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 seat position,
front passenger weight and front seat belt usage, which allow for further controlling of the
system.
Driver seat slide position sensor
Your vehicle is equipped with a driver seat slide 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 crash
sensors and diagnostic module (SAS unit). The sensor is also 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 2-53).
How the Air Bags Work
The front air bags will deploy only
in a frontal or frontal offset impact.
