* If the front passenger seat belt is buckled, the front passenger air bag deactivation indicator light illuminates,
however this does not indicate a malfunction.
If the front passenger air bag deactivation indicator light does not illuminate when the
ignition switch is turned to the ON position and does not illuminate as indicated in the
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.

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

belt pretensioner units must be
replaced after any collision which
caused them to deploy or damage
them. Only a trained Authorized

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
