Seat Belt Systems
Form No. 8S18-EA-03I
For optimum protection, the driver and
front passenger seat belts are equipped
with pretensioner and load limiting
systems.
In moderate or greater frontal or near-
frontal accidents, the front air bag and
pretensioner systems deploy
simultaneously. The pretensioners take up
slack in the front seat belts as the air bags
are expanding. The seat belt pretensioner
system will not activate if the seat belt is
not fastened, only you can be sure it is
worn properly. The load limiting system
releases belt webbing in a controlled
manner to reduce belt force on the
occupant’s chest.
Front Seat Belt
Pretensioner and Load
Limiting Systems
Incorrect Positioning of the Driver
and Front Passenger Seat Belts:
Incorrect positioning of the driver
and passenger seat belts is dangerous.
Without proper positioning, the
pretensioner and load limiting
systems cannot provide adequate
protection in an accident and this
could result in serious injury. Wear
seat belts only as recommended in
this owner’s manual.
WARNING
Expended Seat Belt Pretensioners:
Use of front seat belts with the
pretensioner system expended is
dangerous.
The seat belt pretensioners will only
function once. After they are
expended, they will not work again
and must be replaced immediately.
If the seat belt pretensioners are not
replaced, the risk of injury in a
collision will increase.
Always have an Authorized Mazda
Dealer inspect the seat belt
pretensioners and air bags after any
collision. The seat belt pretensioners
and air bags must be replaced after
any collision, which causes them to
deploy.
Modification or Testing of 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. Never
modify the components or wiring, or
use electronic testing devices on the
pretensioner system.

Modification of 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. Don’t 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
electric 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
•When 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.
•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.

Driver and front passenger buckle switches
The buckle switches on the front seat belts detect whether or not the front seat belts are
securely fastened and further control the deployment of the air bags on the front seats.

How the Side and Curtain Air Bags Work*
When air bag crash sensors detect a side impact of greater than moderate force, an
electrical current is sent to the inflators.
Gases are produced to inflate the side and curtain air bags and after the inflation, the side
and curtain air bags quickly deflate.
The side and curtain air bags will function only once. After that, the side and curtain air
bags will not work again and must be replaced.
Only an Authorized Mazda Dealer can
replace the systems.
NOTE
•The system requires about 10 seconds to alternate between turning the front
passenger front and side air bags and seat belt pretensioner system on or off.
•The front passenger air bag deactivation indicator light may illuminate repeatedly if
luggage or other items are put on the front passenger seat, or if the temperature of the
vehicle’s interior changes suddenly.
•The front passenger air bag deactivation indicator light may illuminate for 10 seconds
if the total seated weight on the front passenger seat changes.
•
If the front passenger air bag deactivation indicator light does not illuminate after
installing a child-restraint system on the front passenger seat, install the child-restraint
system on the rear seat and consult an Authorized Mazda Dealer as soon as possible.
To prevent damage to the side and curtain air bag wiring, don’t place luggage or other
objects under the front seats.
The side air bag will deploy only on the side
the vehicle receives the force of the impact.The curtain air bag will deploy only on the side
the vehicle receives the force of the impact.
CAUTION
*Some models.

Constant Monitoring
The following components of the air bag
systems are monitored by a diagnostic
system:
•SAS unit
•Front air bag sensor
•Air bag modules
•Side crash sensor
*
•Front seat belt pretensioners
•Related wiring
•Driver seat slide position sensor
•Front passenger seat weight sensors
•Driver and front passenger seat belt
buckle switches
The diagnostic module continuously
monitors the system’s readiness. This
begins when the ignition switch is turned
to the ON position and continues while
the vehicle is being driven.

Air Bag/Front Seat Belt
Pretensioner System Warning
Light
If the air bag/front seat belt pretensioner
system is normal, the warning light
illuminates when the ignition switch is
turned to the ON position or after the
engine is cranked. After about 6 seconds it
goes out.
A system malfunction is indicated when
the warning light constantly flashes,
illuminates or doesn’t illuminate at all
when the ignition switch is turned to the
ON position. If any of these occur, consult
an Authorized Mazda Dealer as soon as
possible. The system may not work in an
accident.
Self-Servicing the Air Bag/
Pretensioner Systems:
Self-servicing or tampering with the
systems is dangerous. An air bag/
pretensioner could accidentally
activate or become disabled. This
could cause serious injuries. Never
tamper with the systems and always
have an Authorized Mazda Dealer
perform all servicing and repairs.

Damaged Air Bag System
Components:
Driving with damaged air bag system
components is dangerous. A collision,
even one not strong enough to inflate
the air bags, could damage the system
components. If there was a
subsequent collision, a damaged
component would not inflate the air
bags. Always have an Authorized
Mazda Dealer inspect the air bag
systems after a collision.
Removing Interior Parts:
Removing any components such as
the front seats (if side air bags are
equipped), 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.
Air Bag Disposal:
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.
WARNINGNOTE
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).
