WARNING
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.

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.

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.

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.

*Some models.
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.
