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
2-54).
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.
Refer to Warning/Indicator Lights on page
4-23.

Essential Safety Equipment
Seat Belt Systems
(With Front Passenger Occupant
Classification System)
In addition, the pretensioner system for
the front passenger, like the front and side
passenger air bag, is designed to only
deploy when the front passenger occupant
classification sensor detects a passenger
sitting on the front passenger's seat.
For details, refer to the front passenger
occupant classification sensor (page
2-57).
Load limiter:
The load limiting system releases belt
webbing in a controlled manner to reduce
belt force on the occupant's chest. While
the most severe load on a seat belt occurs
in frontal collisions, the load limiter has
an automatic mechanical function and
can activate in any accident mode with
sufficient occupant movement.
Even if the pretensioners have not fired,
the load limiting function must be checked
by an Authorized Mazda Dealer.
WARNING
Wear seat belts only as recommended in
this owner's manual: Incorrect positioning of the driver
and front 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.
For more details about wearing seat
belts, refer to "Fastening the seat belts"
(page
2-17). Have your seat belts changed
immediately if the pretensioner or load
limiter has been expended:
Always have an Authorized Mazda
Dealer immediately inspect the seat
belt pretensioners and air bags after
any collision. Like the air bags, the 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 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. Have an Authorized
Mazda Dealer safely dispose of
the pretensioner system or scrap a
pretensioner system equipped vehicle.

NOTE
 The pretensioner system may not
operate depending on the type of the
collision. For details, refer to the SRS
Air Bag Deployment Criteria (page
2-54). Some 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.
Seat Belt Extender
If your seat belt is not long enough, even
when fully extended, a seat belt extender
may be available to you at no charge from
your Authorized Mazda Dealer.
This extender will be only for you and for
the particular vehicle and seat. Even if it
plugs into other seat belts, it may not hold
in the critical moment of a crash.
When ordering an extender, only order
one that provides the necessary additional
length to fasten the seat belt properly.
Please contact your Authorized Mazda
Dealer for more information.
WARNING
Do not use a seat belt extender unless it
is necessary:Using a seat belt extender when not
necessary is dangerous. The seat belt
will be too long and not fit properly.
In an accident, the seat belt will not
provide adequate protection and you
could be seriously injured. Only use the
extender when it is required to fasten
the seat belt properly.

Essential Safety Equipment
Seat Belt Systems
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.

Child-Restraint
Child-Restraint Precautions
Mazda strongly urges the use of child-restraint systems for children small enough to use \
them.
You are required by law to use a child-restraint system for children in the U.S. and Canada.
Check your local and state or provincial laws for specific requirements regarding the safety
of children riding in your vehicle.
Whatever child-restraint system you consider, please pick the appropriate one for the age
and size of the child, obey the law and follow the instructions that com\
e with the individual
child-restraint system.
A child who has outgrown child-restraint systems should sit in the rear a\
nd use seat belts,
both lap and shoulder. If the shoulder belt crosses the neck or face, move the child closer
to the center of the vehicle in the outboard seats, and towards the buck\
le on the right if the
child is seated on the center seat.
Statistics confirm that the rear seat is the best place for all children up to 12 years of age,
and more so with a supplemental restraint system (air bags).
A rear-facing child-restraint system should NEVER be used on the front seat with the air
bag system activated. The front passenger's seat is also the least preferred seat for other
child-restraint systems.
(With Front Passenger Occupant Classification System)
To reduce the chance of injuries caused by deployment of the front passen\
ger air bag, the
front passenger occupant classification sensor works as a part of the supplemental restraint
system. This system deactivates the front passenger front and side air bags and \
also the
front passenger seat belt pretensioner system when the front passenger a\
ir bag deactivation
indicator light illuminates.
When an infant or small child sits on the front passenger seat, the syst\
em shuts off the front
passenger front and side air bags and seat belt pretensioner system, so \
make sure the front
passenger air bag deactivation indicator light illuminates.
Even if the front passenger air bag is shut off, Mazda strongly recommends that children be
properly restrained and child-restraint systems of all kinds are properl\
y secured on the rear
seats which are the best place for children.
For more details, refer to "Front passenger occupant classification sensor" (page
2-57).

Essential Safety Equipment
Child-Restraint
WARNING
Use the correct size child-restraint system:
For effective protection in vehicle accidents and sudden stops, a child must be properly
restrained using a seat belt or child-restraint system depending on age and size. If not, the
child could be seriously injured or even killed in an accident.
Follow the manufacturer's instructions and always keep the child-restraint system
buckled down: An unsecured child-restraint system is dangerous. In a sudden stop or a collision it could
move causing serious injury or death to the child or other occupants. Make sure any
child-restraint system is properly secured in place according to the child-restraint system
manufacturer's instructions. When not in use, remove it from the vehicle or fasten it
with a seat belt, or latch it down to BOTH LATCH lower anchors for LATCH child-restraint
systems and the corresponding tether anchor.
Always secure a child in a proper child-restraint system: Holding a child in your arms while the vehicle is moving is extremely dangerous. No
matter how strong the person may be, he or she cannot hold onto a child in a sudden
stop or collision and it could result in serious injury or death to the child or other
occupants. Even in a moderate accident, the child may be exposed to air bag forces that
could result in serious injury or death to the child, or the child may be slammed into an
adult, causing injury to both child and adult.

Essential Safety Equipment
Child-Restraint
Never use a rear-facing child-restraint system in the front seat with an air bag that
could deploy:Rear-facing child-restraint systems on the front seat are particularly dangerous even
though you may feel assured that a front passenger air bag will not deploy based on
the fact that the front passenger air bag deactivation indicator light illuminates. The
child-restraint system can be hit by a deploying air bag and moved violently backward
resulting in serious injury or death to the child.
(Except Mexico)
Vehicles with a front passenger air bag have the following warning label. The warning
label reminds you not to put a rear-facing child-restraint system on the front passenger
seat at any time.
(Mexico)
NEVER use a rearward facing child restraint on a seat protected by an ACTIVE AIRBAG in
front of it, DEATH or SERIOUS INJURY to the CHILD can occur.
Vehicles with a front passenger air bag have the following warning label. The warning
label reminds you not to put a rear-facing child-restraint system on the front passenger
seat at any time.

Essential Safety Equipment
Child-Restraint
Do not install a front-facing child-restraint system on the front passenger seat unless it
is unavoidable:In a collision, the force of a deploying air bag could cause serious injury or death to the
child. If installing a front-facing child-restraint system on the front passenger seat is
unavoidable, move the front passenger seat as far back as possible.
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 indicator 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 the rear seats are the safest places for
children. Always use seat belts and child restraints.

Essential Safety Equipment
Child-Restraint
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 against 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 out of the
front seat, the rear seat is always a better location for children. Take special care not to
allow a child to lean over or against the side window, even if the child is seated in a child-
restraint system.
Never use one seat belt on more than one person at a time: Using one seat belt for more than one person at a time is dangerous. A seat belt used
in this way cannot spread the impact forces properly and the two passengers could
be crushed together and seriously injured or even killed. Never use one belt for more
than one person at a time and always operate the vehicle with each occupant properly
restrained.
CAUTION
A seat belt or child-restraint system can become very hot in a closed vehicle during warm
weather. To avoid burning yourself or a child, check them before you or your child touches
them.
NOTE
Your Mazda is equipped with LATCH lower anchors for attachment of specially designed
LATCH child-restraint systems in the rear seats. When using these anchors to secure a
child-restraint system, refer to "Using LATCH Lower Anchor" (page
2-37).
