WARNING
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
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. 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
lWhen 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.
lShould 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 Air Bags Work
qHow 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 system components.
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.
The front air bags will deploy only
in a frontal or frontal offset impact.
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).

Front passenger seat weight sensors
If your vehicle is equipped with front passenger seat weight sensors, a front passenger air
bag deactivation indicator light is also equipped (page 2-30). These sensors are located
under both of the front passenger seat rails. These sensors determine the total seated weight
on the front passenger seat. The sensors are also designed to prevent the front passenger
front and side air bags and seat belt pretensioner system from inflating if the total seated
weight is less than approximately 30 kg (66 lb).
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:
lThere is no passenger in the front passenger seat. (The front passenger air bag
deactivation indicator light does not illuminate.)
lThe total seated weight on the front passenger seat is less than approximately 30 kg (66
lb). (The front passenger air bag deactivation indicator light illuminates.)
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 chart below.
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.
Front passenger air bag deactivation indicator light
This indicator light illuminates to remind you that the front passenger front and side air
bags and seat belt pretensioner will not deploy during a collision.
With seat warmer Without seat warmer
If the front passenger weight sensors are normal, the indicator light illuminates when the
ignition switch is turned to the ON position. After about 6 seconds it goes out.

above 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.
WARNING
Decreasing 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 from the total seated weight of
approximately 42 kg (93 lb) 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 from the total seated weight of
approximately 42 kg (93 lb) could result in an air bag not deploying under the
following conditions, for example:
lA rear passenger pushes up on the front passenger seat with the feet.lLuggage 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.
lThe 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 rim of the moonroof and sitting with the seatback reclined too far.
lAny 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 total seated weight on the front passenger seat is close to 30 kg (66 lb)
and they will reactivate before the weight exceeds 42 kg (93 lb).

WARNING
Increasing 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 the front passenger seat from the total seated weight of
approximately 30 kg (66 lb) 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 seat belt pretensioner
system in an accident and serious injury. Increasing the total seated weight on the
front passenger seat beyond the total seated weight of approximately 30 kg (66 lb)
could result in the front passenger front and side air bags and seat belt pretensioner
system deployment in an accident under the following conditions, for example:
lLuggage or other items are placed on the seat with the child in the child-restraint
system.
lA rear passenger or luggage push or pull down on the front passenger seatback.lA rear passenger steps on the front passenger seat rails with the feet.lLuggage or other items are placed on the seatback or hung on the head restraint.lThe seat is washed.lLiquids are spilled on the seat.lThe front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
lThe front passenger seatback contacts the rear seat.lLuggage or other items are placed between the front passenger seat and driver seat.lAny accessories which might increase 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 total seated weight on the front passenger seat is close to 30 kg (66 lb)
and they will reactivate before the weight exceeds 42 kg (93 lb).
CAUTION
lTo assure proper deployment of the front air bag and to prevent damage to the sensors
in the front seat bottoms:
lDo not place sharp objects on the front seat bottoms or leave heavy luggage on
them.
lDo not spill any liquids on the front seats or under the front seats.
lTo allow the sensors to function properly, always perform the following:
lAdjust the front seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.
lIf you place your child on the front passenger seat, secure the child-restraint system
properly and slide the front passenger seat as far back as possible (page 2-30).

NOTE
lThe system requires about 10 seconds to alternate between turning the front passenger
front and side air bags and seat belt pretensioner system on or off.
lThe front passenger air bag deactivation indicator light may illuminate repeatedly if
luggage or other items are put on the front passenger seat, or if the temperature of the
vehicle's interior changes suddenly.
lThe front passenger air bag deactivation indicator light may illuminate for 10 seconds
if the total seated weight on the front passenger seat changes.
lIf the front passenger air bag deactivation indicator light does not illuminate after
installing a child-restraint system on the front passenger seat, install the child-restraint
system on the rear seat and consult an Authorized Mazda Dealer as soon as possible.
Driver and front passenger buckle switches
The buckle switches on the front seat belts detect whether or not the front seat belts are
securely fastened and further control the deployment of the air bags.
qHow the Side and Curtain Air Bags Workí
When air bag crash sensors detect a side impact of greater than moderate force, an
electrical current is sent to the inflators.
Gases are produced to inflate the side and curtain air bags and after the inflation, the side
and curtain air bags quickly deflate.
The side and curtain air bags will function only once. After that,the side and curtain air
bags will not work again and must be replaced.Only an Authorized Mazda Dealer can
replace the systems.
The side and curtain air bags will deploy only on the
side the vehicle receives the force of the impact.

WARNING
Damaged Side and Curtain Air Bag Wiring under the Front Seats:
Placing luggage or other objects under the front seats is dangerous. The side and
curtain air bag wiring could be damaged, and in the event of a side collision, the side
and curtain air bags may not deploy, which could result in death or serious injury. To
prevent damage to the side and curtain air bag wiring, do not place luggage or other
objects under the front seats.
qAir Bag Activation/Deactivation
NOTE
If the front passenger seat weight sensors detect a total seated weight on the front
passenger seat is less than approximately 42 kg (93 lb), the front passenger front and side
air bags and seat belt pretensioner may not inflate (page 2-45).
Front air bag activation
A greater than moderate impact will cause
the front air bags to inflate in the
following cases:
lHitting a solid wall straight on at
greater than about 22 km/h (14 mph).
lHitting a curb, pavement edge or hard
object.
lLanding hard or the vehicle falling.
lFrontal impact within about a 30
degree range from head-on to the
vehicle.
