2009 MAZDA MODEL 3 HATCHBACK Owner's Manual (in English)

Black plate (65,1)
WARNING
Do not decrease 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 lbs) 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 lbs) could result in an air bag not deploying under
the following conditions, for example:
ØA rear passenger pushes up on the front passenger seat with their feet.
Ø Luggage 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.
Ø The 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 assist grip or the rim of the moonroof and sitting with the seatback
reclined too far.
Ø Any 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
lbs) and they will reactivate before the weight exceeds 42 kg (93 lbs).

Do not increase 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 lbs) 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 may cause serious injury. Increasing the total seated
weight on the front passenger seat beyond the total seated weight of approximately
30 kg (66 lbs) 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:
ØLuggage or other items are placed on the seat with the child in the child-restraint
system.
Ø A rear passenger or luggage push or pull down on the front passenger seatback.
Ø A rear passenger steps on the front passenger seat rails with their feet.
Ø Luggage or other items are placed on the seatback or hung on the head restraint.
Ø The seat is washed.
Ø Liquids are spilled on the seat.
Ø The front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
Ø The front passenger seatback contacts the rear seat.
Ø Luggage or other items are placed between the front passenger seat and driver
seat.
Ø Any 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 less than
approximately 30 kg (66 lbs) and they will reactivate when the weight exceeds
approximately 42 kg (93 lbs).
CAUTION
Ø To assure proper deployment of the front air bag and to prevent damage to the
sensors in the front seat bottoms:
ØDo not place sharp objects on the front seat bottoms or leave heavy luggage on
them.
ØDo not spill any liquids on the front seats or under the front seats.
Ø To allow the sensors to function properly, always perform the following:
ØAdjust the front seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.
ØIf 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
2-35).

NOTElThe 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. However, the side air bag system for the front
passenger is designed to only deploy in accordance with the total seated weight on the front
passenger seat, however the curtains are not deactivated.
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.
