WARNING
Do not place luggage or other objects under the front seats:
Placing luggage or other objects under the front seats is dangerous. The components
essential to the supplementary restraint system could be damaged, and in the event of
a side collision, the appropriate air bags may not deploy, which could result in death
or serious injury. To prevent damage to the components essential to the supplementary
restraint system, do not place luggage or other objects under the front seats.

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 expert repairer, we recommend an Authorised Mazda Repairer 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 front seats, front instrument panel, 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
Authorised Mazda Repairer remove these parts.

Properly dispose of the air bag system:
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 could result. Have an
expert repairer, we recommend an Authorised Mazda Repairer safely dispose of the air
bag system or scrap an air bag equipped vehicle.

NOTE
  When an air bag deploys, a loud inÀ ation 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.
  This highly-visible label warns against the use of a rear-facing child-restraint system
on the front passenger seat.

Front Passenger Air Bag Deactivation Switch *
WARNING
Do not deactivate the front passenger air bag unnecessarily:
Unnecessary deactivation of the front passenger air bag is dangerous. If turned off
unnecessarily, the front passenger will not receive the added protection of the air bag.
Serious injuries or even death could occur. With the exception of installing a child-
restraint system on the front passenger seat, do not turn the air bag deactivation switch
to the OFF position.



The front passenger air bag deactivation switch should be used to deactivate the front
passenger front and side air bags and also the front passenger seat belt pretensioner system
if installing a child-restraint system on the front passenger seat.

When the ignition is switched ON, both front passenger air bag deactivation indicator
lights illuminate regardless of the front passenger air bag deactivation switch position. The
indicator light turns off after a speci¿ ed period of time, then turns on/off depending on the
conditions as indicated in the following table.

switch is in ON position).
Switch Positions
Before driving, always con¿ rm that the front passenger air bag deactivation switch is in the
appropriate position using the auxiliary key according to your requirements.
WARNING
Do not leave the key in the front passenger air bag deactivation switch:
Unintentional deactivation of the front passenger air bag is dangerous. In an accident,
the front passenger will not be properly protected. Serious injuries or even death
could occur. To avoid unintentional deactivation, always use the auxiliary key stored
in the transmitter body currently being used to operate the front passenger air bag
deactivation switch. After deactivating the air bag, put the auxiliary key back into the
transmitter body. That way you will not leave the key in the front passenger air bag
deactivation switch.

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.
Seat Belt Pretensioners
The pretensioners operate differently depending on what types of air bags are equipped. For
more details about seat belt pretensioner operation, refer to the SRS Air Bag Deployment
Criteria (page 2-55 ).
Front
The front seat belt pretensioners are designed to deploy in moderate or severe frontal, near
frontal collisions. In addition, during a side collision, the pretensioner operates on the side in
which the collision occurs.
Rear Outboard
*
The rear outboard seat belt pretensioners are designed to deploy in moderate or severe
frontal, near frontal collisions.

Essential Safety Equipment
SRS Air Bags
Driver 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 inÀ ates 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 2-55 ).
(With Front Passenger Air Bag Deactivation Switch)
The inÀ ation of the driver's dual-stage air bag is controlled in two energy stages depending
on the driver's seat position. The driver's seat slide position sensor is located under the
driver's seat. The sensor determines whether the driver's seat is forward of or behind 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's air bag depending on how close the
driver's seat is to the steering wheel.
During an impact of moderate severity, the driver's air bag deploys with lesser energy,
whereas during more severe impacts and when the driver's seat is behind the reference
position, it deploys with more energy.

Front Passenger Air Bag
The front passenger air bag is mounted in the front passenger instrument panel.
The inÀ ation mechanism for the front passenger air bag is the same as the driver's air bag.
For more details about air bag deployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-55 ).


Side 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 inÀ ates the side air bag only on the side in which the vehicle was hit. The side
air bag inÀ ates 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 2-55 ).

SRS Air Bags
*Some models.
Curtain Air Bags *
The curtain air bags are mounted in the front and rear window pillars, and the roof edge
along both sides.
When the air bag crash sensors detect a side impact of greater than moderate force, the
curtain air bag inÀ ates quickly and helps to reduce injury mainly to the rear outboard
passenger's head 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 2-55 ).


Only one side curtain air bag will deploy on the
side of the vehicle that receives the force of an
impact.
