Front passenger seat weight sensors
Your vehicle is equipped with front passenger seat weight sensors as a part of the
supplemental restraint system. 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 air bag 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:
•There is no passenger in the front passenger seat. (The front passenger air bag
deactivation indicator light does not illuminate.)
•The 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.
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.

The front passenger air bag deactivation indicator light illuminates or is off under the
following conditions:
*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.

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:
•A rear passenger pushes up on the front passenger seat with the feet.
•Luggage or other items placed under the front passenger seat or between the front
passenger seat and front passenger seat side table that push up the front passenger
seat bottom.
•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 sunroof.
•The front passenger seatback contacts the second-row seat.
•Any accessories such as decreasing the total seated weight on the front passenger
seat are attached to the front passenger seat.

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 from 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:
•Luggage or other items are placed on the seat with the child in the child-restraint
system.
•A rear passenger or luggage push or pull down on the front passenger seatback.
•A rear passenger steps on the front passenger seat rails with the feet.
•Luggage or other items are placed on the seatback or hung on the assist grip, head
restraint or armrest.
•The seat is washed.
•Liquids are spilled on the seat.
•The front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
•The front passenger seatback contacts the second-row seat.
•Luggage or other items are placed between the front passenger seat and front
passenger seat side table.
•Any accessories such as increasing the total seated weight on the front passenger
seat are attached to the front passenger seat.
•To assure proper deployment of the front air bag and to prevent damage to the sensors
in the front seat bottoms:
Do not place sharp objects on the front seat bottoms or leave heavy luggage on them.
Do not spill any liquids on the front seats or under the front seats.
•To allow the sensors to function properly, always perform the following:
Adjust the front seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.
If 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 2-51).

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 on the front seats.

How the Side Air Bags Work*
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 air bags and after the inflation, the side air bags
quickly deflate.
The side air bags will function only once. After that, the side air bags will not work again
and must be replaced.
Only an Authorized Mazda Dealer can replace the systems.
NOTE
•The 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.
•The 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.
•The front passenger air bag deactivation indicator light may illuminate for 10 seconds
if the total seated weight on the front passenger seat changes.
•If 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.
To prevent damage to the side air bag wiring, don’t place luggage or other objects under
the front seats.
The side air bag will deploy
only on the side the vehicle receives
the force of the impact.
CAUTION
*Some models.
