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 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 passenger seat
weight sensors are not damaged and that the seats retain an undamaged air bag
connection.

NOTE

When 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.

Should 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 SRS Air Bags Work

Your Mazda is equipped with the following types of SRS air bags. SRS air bags are
designed to work together with the seat belts to help to reduce injuries during an accident.
The SRS air bags are designed to provide further protection for passengers in addition to
the seat belt functions. Be sure to wear seat belts properly.

qSeat Belt Pretensioners

The seat belt pretensioners are designed to deploy in moderate or severe frontal, near
frontal collisions. The pretensioners operate differently depending on what types of air
bags are equipped. For details on the seat belt pretensioner operation, refer to

“SRS Air

Bag Deployment Criteria

” (page 2-34).

qDriver Air Bag

The driver's air bag is mounted in the steering wheel.
When air bag crash sensors detect a frontal impact of greater than moderate force, the
driver's air bag inflates quickly helping to reduce injury mainly to the driver's head or chest
caused by directly hitting the steering wheel.
For more details about air bag deployment, refer to

“SRS Air Bag Deployment Criteria”

(page 2-34).
The driver's dual-stage air bag controls air bag inflation in two energy stages. During an
impact of moderate severity the driver's air bag deploys with lesser energy, whereas during
more severe impacts, it deploys with more energy.

qPassenger Air Bag

The passenger air bag is mounted in the passenger dashboard.
The inflation mechanism for the passenger air bag is the same as the driver's air bag, as
mentioned above.
For more details about air bag deployment, refer to

“SRS Air Bag Deployment Criteria”

(page 2-34).
In addition, the passenger air bag is designed to only deploy in accordance with the total
seated weight on the passenger seat. For details, refer to the driver and passenger occupant
classification system (page 2-37).

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.
For more details about air bag deployment, refer to

“SRS Air Bag Deployment Criteria”

(page 2-34).
In addition, the passenger side air bag is designed to only deploy in accordance with the
total seated weight on the passenger seat. For details, refer to the driver and passenger
occupant classification system (page 2-37).

qAir Bag/Seat Belt Pretensioner System Warning Light

If the air bag/seat belt pretensioner system is working properly, the warning light
illuminates when the ignition is switched ON or after the engine is cranked. The warning
light turns off after a specified period of time.

A system malfunction is indicated if the warning light constantly flashes, constantly
illuminates or does not illuminate at all when the ignition is switched ON. If any of these
occur, consult an Authorized Mazda Dealer as soon as possible. The system may not
operate in an accident.

Driver and Passenger Occupant Classification System

First, please read

“Supplemental Restraint System (SRS) Precautions” (page 2-25)

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/seat belt pretensioner system warning light flashes if the sensor has a possible
malfunction (page 2-32).

qPassenger Seat Weight Sensors

Your vehicle is equipped with a passenger seat weight sensors as a part of the supplemental
restraint system. These sensors are located under both of the passenger seat rails. These
sensors determine the total seated weight on the passenger seat and monitor the seat belt
buckle for the passenger seat. The SAS unit is designed to prevent the passenger front and
side air bags and seat belt pretensioner system from deploying if the passenger air bag
deactivation indicator light illuminates.
To reduce the chance of injuries caused by deployment of the passenger air bag, the system
deactivates the passenger front and side air bags and also the seat belt pretensioner system
when the passenger air bag deactivation indicator light illuminates. Refer to the following
table for the passenger air bag deactivation indicator light illumination conditions.

This system shuts off the passenger front and side air bags and seat belt pretensioner
system, so make sure the passenger air bag deactivation indicator light illuminates
according to the following table.

The air bag seat belt pretensioner system warning light flashes and the passenger air bag
deactivation indicator light illuminates if the sensors have a possible malfunction. If this
happens, the passenger front and side air bags and seat belt pretensioner system will not
deploy.

WARNING

Do not decrease the total seated weight on the passenger seat:

When an adult or large child sits on the passenger seat, decreasing the total seated
weight on the passenger seat required for air bag deployment is dangerous. The
passenger seat weight sensors will detect the reduced total seated weight condition
and the passenger front and side air bags and seat belt pretensioner system will not
deploy during an accident. The passenger will not have the supplementary protection
of the air bag, which could result in serious injury. Decreasing the total seated
weight on the passenger seat could result in an air bag not deploying under the
following conditions, for example:

Ø Luggage or other items placed under the passenger seat or between the passenger

seat and center console that push up the passenger seat bottom.

Ø The passenger seat occupant sits in a manner such that the occupant's entire

weight is not placed on the seat sitting too close to the door.

Ø Any accessories which might decrease the total seated weight on the passenger

seat are attached to the passenger seat.

The passenger front and side air bags and seat belt pretensioner systems will
deactivate if the passenger air bag deactivation indicator light illuminates.

Do not increase the total seated weight on the passenger seat:

When an infant or small child sits on the passenger seat, increasing the total seated
weight on the passenger seat is dangerous. The passenger seat weight sensors will
detect the increased total seated weight, which could result in the unexpected
deployment of the 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 passenger seat could result in the passenger front and side air bags
and seat belt pretensioner system deployment in an accident under the following
conditions, for example:

Ø The passenger air bag deactivation indicator light does not illuminate when

seating a child in the child-restraint system.

Ø Luggage or other items are placed on the seat with the child in the child-restraint

system.

Ø The seat is washed.

Ø Liquids are spilled on the seat.

Ø The passenger seat is moved backward, and it is pushed into luggage or other

items placed behind it.

Ø Luggage or other items are placed between the passenger seat and center

console.

Ø Any accessories which might increase the total seated weight on the passenger

seat are attached to the passenger seat.

The passenger front and side air bags and seat belt pretensioner systems will
deactivate if the passenger air bag deactivation indicator light illuminates.

CAUTION

Ø To assure proper deployment of the front air bag and to prevent damage to the

sensors in the seat bottoms:

Do not place sharp objects on the seat bottoms or leave heavy luggage on
them.

Do not spill any liquids on the seats or under the seats.

Ø To allow the sensors to function properly, always perform the following:

Adjust the 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 passenger seat, secure the child-restraint system
properly and slide the passenger seat as far back as possible.

NOTE

The system requires about 10 seconds to alternate between turning the passenger front and side
air bags and seat belt pretensioner system on or off.

The passenger air bag deactivation indicator light may illuminate repeatedly if luggage or other
items are put on the passenger seat, or if the temperature of the vehicle's interior changes
suddenly.

The passenger air bag deactivation indicator light may illuminate for 10 seconds if the total
seated weight on the passenger seat changes.

The air bag seat belt pretensioner system warning light might illuminate if the passenger seat
receives a severe impact.

If the passenger air bag deactivation indicator light illuminates when an adult is seated in the
passenger seat, have the passenger re-adjust their posture by sitting with their feet on the floor,
and then re-fastening the seat belt. If the passenger air bag deactivation indicator light still
illuminates, slide the passenger seat as far back as possible. Consult an Authorized Mazda Dealer
as soon as possible.

qDriver and 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.

WARNING

Do not operate a vehicle with damaged air bag/seat belt pretensioner system
components:

Expended or damaged air bag/seat belt pretensioner system components must be
replaced after any collision which caused them to deploy or damage them. Only a
trained Authorized Mazda Dealer can fully evaluate these systems to see that they
will work in any subsequent accident. Driving with an expended or damaged air bag
or pretensioner unit will not afford you the necessary protection in the event of any
subsequent accident which could result in serious injury or death.

Do not remove interior air bag parts:

Removing any components such as the seats, dashboard, the steering wheel or parts
on the front and rear window pillars and along the roof edge, containing air bag
parts or sensors is dangerous. These parts contain essential air bag components. The
air bag could accidentally activate and cause serious injuries. Always have an
Authorized Mazda Dealer remove these parts.

Dispose of the air bag properly:

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 Dealer how to safely dispose of an air bag or how to scrap an air
bag equipped vehicle.

NOTE

If it becomes necessary to have the components or wiring system for the supplementary restraint
system modified to accommodate a person with certain medical conditions in accordance with a
certified physician, contact an Authorized Mazda Dealer, refer to
