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 infl ate
unexpectedly, or it could prevent the air bags from infl 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 modifi 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 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
modifi 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 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.
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.

WARNING
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 infl 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.

SRS Air Bags
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.
Front Seat Belt Pretensioners
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. The pretensioners operate differently depending on what types of air bags
are equipped. For details on the seat belt pretensioner operation, refer to the SRS Air Bag
Deployment Criteria (page 2-52 ).
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 infl 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 2-52 ).

SRS Air Bags
Front Passenger Air Bag
The front passenger air bag is mounted in the front passenger instrument panel.
The infl ation mechanism for the front 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 2-52 ).
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 infl ates the side air bag only on the side in which the vehicle was hit. The side
air bag infl 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 2-52 ).

Essential Safety Equipment
SRS Air Bags
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 infl 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 2-52 ).
Only one side curtain air bag will deploy on the
side of the vehicle that receives the force of an
impact.

A system malfunction or operation conditions are indicated by a warning.

NOTE
  The keyless entry system operation
may vary due to local conditions.
  The keyless entry system is fully
operational (door/liftgate/boot lid
lock/unlock) when the ignition is
switched off. The system does not
operate if the ignition is switched to
any position other than off.
  If the key does not operate when
pressing a button or the operational
range becomes too small, the battery
may be dead. To install a new battery,
refer to Key Battery Replacement
(page 6-43 ).
  Battery life is about one year.
Replace the battery with a new one
if the KEY indicator light (green)
fl ashes in the instrument cluster.
Replacing the battery about once
a year is recommended because
the KEY warning light/indicator
light may not illuminate or fl ash
depending on the rate of battery
depletion.
  Additional keys can be obtained at
an Authorised Mazda Repairer. Up to
6 keys can be used with the keyless
functions per vehicle. Bring all keys
to an Authorised Mazda Repairer
when additional keys are required.
