5. Make sure the front passenger air bag
deactivation indicator light illuminates
after installing a child-restraint system
on the front passenger seat.
Refer to Front passenger air bag
deactivation indicator light on page
2-55.WARNING
Do not seat a child in a child-restraint
system on the front passenger seat if
the front passenger air bag
deactivation indicator light does not
illuminate:
While it is always better to install any
child-restraint system on the rear
seat, it is imperative that a child-
restraint systemONLYbe used on the
front passenger seat if the
deactivation indicator light
illuminates when the child is seated
in the child-restraint system (page
2-55). Seating a child in a child-
restraint system installed on the front
passenger seat with the front
passenger air bag deactivation
indicator light not illuminated is
dangerous. If this indicator light does
not illuminate even when the total
seated weight is less than
approximately 30 kg (66 lb), this
means that the front passenger front
and side air bags, and seat belt
pretensioner are ready for
deployment. If an accident were to
deploy an air bag, a child in a child-
restraint system sitting in the front
passenger seat could be seriously
injured or killed. If the indicator light
does not illuminate after seating a
child in a child-restraint system on
the front passenger seat, seat a child
in a child-restraint system on the rear
seat and consult an Authorized
Mazda Dealer as soon as possible.

Do not touch the components of the supplemental restraint system after the air bags
have inflated:
Touching the components of the supplemental restraint system after the air bags
have inflated is dangerous. Immediately after inflation, they are very hot. You could
get burned.
Never install any front-end equipment to your vehicle:
Installation of front-end equipment, such as frontal protection bar (kangaroo bar,
bull bar, push bar, or other similar devices), 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.
Do not modify the suspension:
Modifying the vehicle suspension is dangerous. If the vehicle's height or the
suspension is modified, the vehicle will be unable to accurately detect a collision
resulting in incorrect or unexpected air bag deployment and the possibility of serious
injuries.
Do not modify 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. Do not 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.

qFront Passenger Air Bag
The front passenger air bag is mounted in the front passenger dashboard.
The inflation mechanism for the front passenger air bag is the same as the driver's air bag,
as mentioned above. In addition, the front passenger air bag is designed to only deploy in
accordance with the total seated weight on the front passenger seat. For details, refer to the
driver and front passenger occupant classification system (page 2-55).
qSide Air Bags
The side air bags are mounted in the outboard sides of the front seatbacks.
When the air bag crash sensors detect a side impact of greater than moderate force, the
system inflates the side air bag only on the side in which the vehicle was hit. The side air
bag inflates quickly to reduce injury to the driver or front passenger's chest caused by
directly hitting interior parts such as a door or window. In addition, the front passenger side
air bag is designed to only deploy in accordance with the total seated weight on the front
passenger seat. For details, refer to the driver and front passenger occupant classification
system (page 2-55).

Driver and Front Passenger Occupant Classification System
First, please read“Supplemental Restraint System (SRS) Precautions”(page 2-43)
carefully.
qDriver Seat Slide Position Sensor
Your vehicle is equipped with a driver seat slide position 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 diagnostic module (SAS unit). The SAS unit is 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 2-50).
qFront Passenger Seat Weight Sensors
Your vehicle is equipped with a 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
SAS unit is designed to prevent the front passenger front and side air bags and seat belt
pretensioner system from deploying if the total seated weight is less than approximately 30
kg (66 lbs).
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
lbs). (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 following table.
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.

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.
ØLuggage 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.
ØThe 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.
ØAny 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).
