Essential Safety Equipment
Seat Belt Systems
(With Front Passenger Occupant
Classifi cation System)
In addition, the pretensioner system for
the front passenger, like the front and side
passenger air bag, is designed to only
deploy in accordance with the total seated
weight on the front passenger seat.
For details, refer to the front passenger
seat weight sensors (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
suffi cient occupant movement.
Even if the pretensioners have not fi red,
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 2-16 ).
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. Have an Authorized
Mazda Dealer safely dispose of
the pretensioner system or scrap a
pretensioner system equipped vehicle.

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 t\
he U.S. and Canada.
Check your local and state or provincial laws for specifi c 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 confi rm 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 Classifi cation System)
To reduce the chance of injuries caused by deployment of the front passen\
ger air bag, the
front passenger seat weight sensors work as a part of the supplemental r\
estraint 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 air bag deactivat\
ion 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 seat weight sensors" (page \
2-57 ).

Essential Safety Equipment
Child-Restraint
Seating a child in a child-restraint system on the front passenger seat is dangerous
under certain conditions (With Front Passenger Occupant Classifi cation System) :
Your vehicle is equipped with front passenger seat weight sensors. Even with the front
passenger seat weight sensors, 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.

Essential Safety Equipment
Child-Restraint
Installing Child-Restraint
Systems
Accident statistics reveal that a child is
safer in the rear seat. The front passenger's
seat is clearly the worst choice for any
child under 12, and with rear-facing child-
restraint systems it is clearly unsafe due to
air bags.
NOTE
Even if your vehicle is equipped with front
passenger seat weight sensors (page 2-
57), which automatically deactivates the
front passenger air bag, a rear seat is the
safest place for a child of any age or size.
Some child-restraint systems now come
with tethers and therefore must be
installed on the seats that take tethers
to be effective. In your Mazda, tethered
child-restraint systems can only be
accommodated in the three positions on
the rear seat.
Some child-restraint systems also employ
specially designed LATCH attachments;
refer to "Using LATCH Lower Anchor"
(page 2-37 ).
WARNING
Tethered Child-Restraint Systems Work
Only on Tether-Equipped Rear Seats: Installation of a tether equipped
child-restraint system in the front
passenger's seat defeats the safety
design of the system and will result in
an increased chance of serious injury if
the child-restraint system goes forward
without benefi t of being tethered.
Place tether equipped child-restraint
systems where there are tether
anchors.

(5-Door)

Tether strapForward
Always attach the tether strap to the
correct tether anchor position: Attaching the tether strap to the
incorrect tether anchor position is
dangerous. In a collision, the tether
strap could come off and loosen the
child-restraint system. If the child-
restraint system moves it could result
in death or injury to the child.
If You Must Use the Front Seat for Children
If you cannot put all children in the rear
seat, at least put the smallest children
in the rear and be sure the largest child
up front uses the shoulder belt over the
shoulder.
NEVER put a rear-facing child-restraint
system on the front passenger seat whether
your vehicle is equipped with a seat
weight sensor or not.
This seat is also not set up for tethered
child-restraint systems, put them in one of
the rear seat positions set up with tether
anchors.
Likewise the LATCH child-restraint
system cannot be secured in the front
passenger's seat and should be used in the
rear seat.
Do not allow anyone to sleep against the
side window since your vehicle has side
and curtain air bags, it could cause serious
injuries to an out of position occupant.
As children more often sleep in cars,
it is better to put them in the rear seat.
If installing the child-restraint system
on the front seat is unavoidable, follow
these instructions when using a front-
facing child-restraint system in the front
passenger's seat.
NOTE
 y  To check if your front seats have side air
bags:
 Mazda vehicles equipped with side air bag will have a "SRS AIRBAG" tag on
the outboard shoulder of the front seats.
 y To check if your vehicle has curtain air
bags:
 Mazda vehicles equipped with curtain air bag will have an "SRS AIRBAG"
marking on the window pillars along
the roof edge.

SRS Air Bags
Supplemental Restraint System (SRS) Precautions
The front and side supplemental restraint systems (SRS) include up to \
6 air bags. Please
verify which kinds of air bags are equipped on your vehicle by locating the “SRS
AIRBAG” location indicators. These indicators are visible in the area where the air bags
are installed.
The air bags are installed in the following locations:
 y  The steering wheel hub (driver air bag) y The front passenger dashboard (front passenger air bag) y The outboard sides of the front seatbacks (side air bags) *
 y The front and rear window pillars, and the roof edge along both sides (\
curtain air bags) *
Vehicles with the Front Passenger Occupant Classifi cation System have a sensor which
detects an impending roll-over accident.
The air bag supplemental restraint systems are designed to provide suppl\
emental protection
in certain situations so seat belts are always important in the followin\
g ways:
Without seat belt usage, the air bags cannot provide adequate protection \
during an accident.
Seat belt usage is necessary to:
 y Keep the occupant from being thrown into an infl ating air bag. y Reduce the possibility of injuries during an accident that is not design\
ed for air bag
infl ation, such as rear impact.
 y Reduce the possibility of injuries in frontal, near frontal or side coll\
isions or roll-over
accidents that are not severe enough to activate the air bags.
 y  Reduce the possibility of being thrown from your vehicle. y Reduce the possibility of injuries to lower body and legs during an acci\
dent because the
air bags provide no protection to these parts of the body.
 y  Hold the driver in a position which allows better control of the vehicle\

Essential Safety Equipment
SRS Air Bags
Do not attach objects on or around the area where a side air bag deploys: Attaching objects to the front seat in such a way as to cover the outboard side of the
seat in any way is dangerous. In an accident the object could interfere with the side
air bag, which infl ates from the outboard side of the front seats, impeding the added
protection of the side air bag system or redirecting the air bag in a way that is dangerous.
Furthermore, the bag could be cut open releasing the gas.
Do not hang net bags, map pouches or backpacks with side straps on the front seats.
Never use seat covers on the front seats. Always keep the side air bag modules in your
front seats free to deploy in the event of a side collision.

Do not attach objects on or around the area where a curtain air bag deploys: Attaching objects to the areas where the curtain air bag activates such as on the
windshield glass, side door glass, front and rear window pillars and along the roof edge
and assist grips is dangerous. In an accident the object could interfere with the curtain
air bag, which infl ates from the front and rear window pillars and along the roof edge,
impeding the added protection of the curtain air bag system or redirecting the air bag in
a way that is dangerous. Furthermore, the bag could be cut open releasing the gas.
Do not place hangers or any other objects on the assist grips. When hanging clothes,
hang them on the coat hook directly. Always keep the curtain air bag modules free to
deploy in the event of a side collision or roll-over accident.

Do not touch the components of the supplemental restraint system after the air bags
have infl ated:
Touching the components of the supplemental restraint system after the air bags have
infl ated is dangerous. Immediately after infl ation, they are very hot. You could get burned.

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 aff ected. 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 or roll-over accident
resulting in incorrect or unexpected air bag deployment and the possibility of serious
injuries.
