Seat Belt Warning Systems
If it detects that the occupant seat belt is
unfastened, the warning light or beep
alerts the occupant.
Refer to Warning/Indicator Lights on page
4-23.
Refer to Seat Belt Warning Beep on page
7-38.
Front Seat Belt
Pretensioner and Load Limiting Systems
For optimum protection, the driver and
front passenger seat belts are equipped
with pretensioner and load limiting
systems. For both these systems to work
properly you must wear the seat belt
properly.

Pretensioners:
When a collision is detected, the
pretensioners deploy simultaneously with
the air bags.
For vehicles with the front passenger
occupant classification system, the
pretensioners deploy simultaneously with
the air bags when a roll-over is also
detected.
For deployment details, refer to the SRS
Air Bag Deployment Criteria (page 2-
58).
The front seat belt retractors remove slack
quickly as the air bags are expanding. Any
time the air bags and seat belt
pretensioners have fired they must be
replaced.
A system malfunction or operation
conditions are indicated by a warning.

Do not use an improper extender:
Using a seat belt extender that is for
another person or a different vehicle or seat
is dangerous. The seat belt will not provide
adequate protection and the user could be
seriously injured in an accident. Only use
the extender provided for you and for the
particular vehicle and seat. NEVER use the
extender in a different vehicle or seat. If you
sell your Mazda, do not leave your seat belt
extender in the vehicle. It could be used
accidentally by the new owner of the
vehicle. After removing the seat belt
extender, discard it. Never use the seat belt
extender in any other vehicle you may own
in the future.
Do not use an extender that is too long:
Using an extender that is too long is
dangerous. The seat belt will not fit
properly. In an accident, the seat belt will
not provide adequate protection and you
could be seriously injured. Do not use the
extender or choose one shorter in length if
the distance between the extender's buckle
and the center of the user's body is less
than 15 cm (6 in).Do not leave a seat belt extender
connected to the buckle:
Leaving a seat belt extender connected to
the buckle without using the seat belt is
dangerous. When the seat belt extender is
connected to the driver's seat belt buckle
(or front passenger's seat belt buckle), the
SRS driver's (or front passenger's) air bag
system will determine that the driver (or
front passenger) is wearing the seat belt
even if the driver (or front passenger) is not
wearing it. This condition could cause the
driver's (or front passenger's) air bag to not
activate correctly and result in death or
serious injury in the event of collision.
Always wear the seat belt with the seat belt
extender.
Do not use the seat belt extender when
installing a child-restraint system on the
front or rear passenger seat:
Using a seat belt extender to fasten a
child-restraint system on any seat is
dangerous. Always follow the
child-restraint system manufacturer's
installation instructions and never use a
seat belt extender.
NOTE
When not in use, remove the seat belt
extender and store it in the vehicle. If the
seat belt extender is left connected, the
seat belt extender might get damaged as it
will not retract with the rest of the seat belt
and can easily fall out of the door when
not in use and be damaged. In addition,
the seat belt warning light will not
illuminate and function properly.

Seating a child in a child-restraint system on the front passenger seat is dangerous under
certain conditions (With Front Passenger Occupant Classification System):
Your vehicle is equipped with front passenger occupant classification sensor. Even with the
front passenger occupant classification sensor, if you must use the front passenger seat to
seat a child, using a child-restraint system on the front passenger seat under the following
conditions increases the danger of the front passenger air bag deploying and could result in
serious injury or death to the child.
 The front passenger air bag deactivation indicato r light does not illuminate when seating a
child in the child-restraint system.
 Luggage or other items are placed on the seat with the child in the child-restraint system.
 A rear passenger or luggage pushing or pulling down on the front passenger seatback.
 Luggage or other items are placed on the seatback or hung on the head restraint.
 The seat is washed.
 Liquids are spilled on the seat.
 The front passenger seat is moved backward, pushing into luggage or other items placed
behind it.
 The front passenger seatback contacts the rear seat.
 Luggage or other items are placed between the front passenger seat and driver seat.
 An electric device is put on the front passenger's seat.
 An additional electrical device, such as a seat warmer is installed to the surface of the front
passenger seat.
The designated positions with seat belts on th e rear seats are the safest places for children.
Always use seat belts and child restraints.
Do not allow a child or anyone to lean over or against the side window of a vehicle with side
and curtain air bags:
It is dangerous to allow anyone to lean over or against the side window, the area of the front
passenger seat, the front and rear window pillars and the roof edge along both sides from
which the side and curtain air bags deploy, even if a child-restraint system is used. The impact
of inflation from a side or curtain air bag could cause serious injury or death to an out of
position child. Furthermore, leaning over or ag ainst the front door could block the side and
curtain air bags and eliminate the advantages of supplemental protection. With the front air
bag and the additional side air bag that comes ou t of the front seat, the rear seat is always a
better location for children. Take special care no t to allow a child to lean over or against the
side window, even if the child is seated in a child-restraint system.

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 Authorized
Mazda Dealer safely dispose of the air bag sy stem or 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 8-2).
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 text ure 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 is displayed wh ich warns against the use of a rear-facing
child-restraint system on the front passenger seat.

Front Passenger Occupant Classification System*
First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-44) carefully.
▼Front Passenger Occupant Classification Sensor
Your vehicle is equipped with a front passenger occupant classi
fication sensor as a part of
the supplemental restraint system. This sensor is equipped in t he front passenger's seat
cushion. This sensor measures th e electrostatic capacity of the front passenger's seat. The
SAS unit is designed to prevent the front passenger front and s ide air bags and seat belt
pretensioner system from deployi ng if the front passenger air bag deactivation indicator
light turns on.
To reduce the chance of injuries caused by deployment of the front passenger air bag, the
system deactivates the front passenger front and side air bags and also the seat belt
pretensioner system when the front passenger air bag deactivati on indicator light turns on.
Refer to the following table for the front passenger air bag deactivation indicator light
illumination conditions.

This system shuts off the front passenger front and side air ba gs and seat belt pretensioner
system, so make sure the front passenger air bag deactivation indicator light turns on
according to the following table.

The air bag/front seat belt pretensioner system warning light f lashes and the front passenger
air bag deactivation indicator light illuminates if the sensors have a possible malfunction. If
this happens, the front passenger front and side air bags and s eat belt pretensioner system
will not deploy.
Front passenger air bag deactivation indicator light
This indicator light turns on to r emind you that the front passenger front and side air bags
and seat belt pretensioner will not deploy during a collision.
If the front passenger occupant classification sensor is normal, the indicator light turns on
when the ignition is switched ON. The light turns off after a f ew seconds. Then, the
indicator light turns on or is off under the following conditio ns:

indicator light on/off condition chart, do not allow an occupan t to sit in the front passenger
seat and consult an Authorized M azda Dealer as soon as possible. The system may not work
properly in an accident.
WA R N I N G
Do not allow an occupant in the front passenger's seat to sit with a posture which makes it
difficult for the front passenger occupant classification sensor to detect the occupant
correctly:
Sitting in the front passenger's seat with a posture which makes it difficult for the front
passenger occupant classification sensor to detect the occupant correctly is dangerous. If the
front passenger occupant classification sensor cann ot detect the occupant sitting on the front
passenger's seat correctly, the front passenger front and side air bags and pretensioner system
may not operate (non-deploy) or they may oper ate (deploy) accidentally. The front passenger
will not have the supplementary protection of the air bags or the accidental operation
(deployment) of the air bags could result in serious injury or death.
Under the following conditions, the front passe nger occupant classification sensor cannot
detect a passenger sitting on the front pa ssenger's seat correctly and the deployment/
non-deployment of the air bags cannot be controlled as indicated in the front passenger air
bag deactivation indicator light on/off condition chart. For example:
