WARNING
Sit in the centre of the seat and wear seat belts properly:
Sitting too close to the side air bag modules or placing hands on them, or sleeping up
against the door or hanging out the windows is extremely dangerous. The side and
curtain air bags inÀ ate with great force and speed directly expanding along the door on
the side the car is hit. Serious injury could occur if someone is sitting too close to the
door or leaning against a window, or if rear seat occupants grab the sides of the front
seatbacks. Give the side and curtain air bags room to work by sitting in the centre of the
seat while the vehicle is moving with seat belts worn properly.

Do not attach objects on or around the area where driver and front passenger air bags
deploy:
Attaching an object to the driver and front passenger air bag modules or placing
something in front of them is dangerous. In an accident, an object could interfere with
air bag inÀ ation and injure the occupants.

Do not attach objects on or around the area where a side air bag deploys:
Attaching objects to the front seat in such a way as to cover the outboard side of the seat
in any way is dangerous. In an accident the object could interfere with the side air bag,
which inÀ ates from the outboard side of the front seats, impeding the added protection
of the side air bag system or redirecting the air bag in a way that is dangerous.
Furthermore, the bag could be cut open releasing the gas.
Do not hang net bags, map pouches or backpacks with side straps on the front seats.
Never use seat covers on the front seats. Always keep the side air bag modules in your
front seats free to deploy in the event of a side collision.

Do not attach objects on or around the area where a curtain air bag deploys:
Attaching objects to the areas where the curtain air bag activates such as on the
windscreen glass, side door glass, front and rear window pillars and along the roof edge
and assist grips is dangerous. In an accident the object could interfere with the curtain
air bag, which inÀ ates from the front and rear window pillars and along the roof edge,
impeding the added protection of the curtain air bag system or redirecting the air bag in
a way that is dangerous. Furthermore, the bag could be cut open releasing the gas.
Do not place hangers or any other objects on the assist grips. When hanging clothes,
hang them on the coat hook directly. Always keep the curtain air bag modules free to
deploy in the event of a side collision.

Do not touch the components of the supplementary restraint system after the air bags
have inÀ ated:
Touching the components of the supplementary restraint system after the air bags have
inÀ ated is dangerous. Immediately after inÀ ation, they are very hot. You could get
burned.

WARNING
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 inÀ ate
unexpectedly, or it could prevent the air bags from inÀ ating 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 modi¿ ed, 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 a front door or leave any damage unrepaired. Always have an expert
repairer, we recommend an Authorised Mazda Repairer inspect a damaged front door:
Modifying a front door or leaving any damage unrepaired is dangerous. Each front
door has a side crash sensor as a component of the supplementary restraint system.
If holes are drilled in a front door, a door speaker is left removed, or a damaged door
is left unrepaired, the sensor could be adversely affected causing it to not detect the
pressure of an impact correctly during a side collision. If a sensor does not detect a side
impact correctly, the side and curtain air bags and the front seat belt pretensioner may
not operate normally which could result in serious injury to occupants.

Do not modify the supplementary restraint system:
Modifying the components or wiring of the supplementary restraint system is
dangerous. You could accidentally activate it or make it inoperable. Do not make any
modi¿ cations to the supplementary 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 expert repairer, we
recommend an Authorised Mazda Repairer 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, and that the driver
seat slide position sensor is not damaged and the seats retain an undamaged air bag
connection.

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.

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 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.

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 2-56 ).
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.
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 2-56 ).
