Have your seat belts changed
immediately if the pretensioner or load
limiter has been expended:Always have an Authorized Mazda
Dealer immediately inspect the front
seat belt pretensioners and air bags
after any collision. Like the air bags,
the front seat belt pretensioners and
load limiters will only function once
and must be replaced after any
collision that caused them to deploy.
A seat belt with an expended
pretensioner or load limiter is still
better than wearing no seat belt at
all; however, if the front seat belt
pretensioners and load limiters are
not replaced, the risk of injury in a
collision will increase.
Do not modify the components or
wiring, or use electronic testing devices
on the pretensioner system: Modifying the components or wiring
of the pretensioner system, including
the use of electronic testing devices is
dangerous. You could accidentally
activate it or make it inoperable
which would prevent it from
activating in an accident. The
occupants or repairers could be
seriously injured.
Properly dispose of the pretensioner
system: Improper disposal of the pretensioner
system or a vehicle with non-
deactivated pretensioners is
dangerous. Unless all safety
procedures are followed, injury could
result. Ask an Authorized Mazda
Dealer how to safely dispose of the
pretensioner system or how to scrap
a pretensioner-equipped vehicle. NOTElThe pretensioner system will activate in a
moderate or greater frontal or near-frontal
collision. It will not activate in most
rollovers, side or rear impacts.
(With Driver and Front Passenger
Occupant Classification System)
The pretensioner system will activate in a
severe side collision.
In addition, the pretensioner system for the
front passenger is designed to only deploy
in accordance with the total seated weight
on the front passenger seat.
lSome smoke (non-toxic gas) will be
released when the air bags and
pretensioners deploy. This does not indicate
a fire. This gas normally has no effect on
occupants, however, those with sensitive
skin may experience light skin irritation. If
residue from the deployment of the air bags
or the front pretensioner system gets on the
skin or in the eyes, wash it off as soon as
possible.
qAir Bag/Front Seat Belt
Pretensioner System Warning Light
If the air bag/front 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.

Do not modify the suspension:Modifying the vehicle suspension is dangerous. If the vehicle's height or the
suspension is modified, 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
Authorized Mazda Dealer 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 supplemental 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 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 front
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 front
passenger seat weight sensors are not damaged and that the seats retain an
undamaged air bag connection.
NOTE
lWhen 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.
lShould 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.
lOn some models, a highly-visible label is displayed which warns against the use of rear-facing
child-restraint systems on the front passenger seat.

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 front seats, front 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 “Customer Assistance (U.S.A.) ”
(page 9-2).
