Always sit in a passenger seat properly
with the seatback upright and feet on
the floor:
If your vehicle is equipped with front
passenger seat weight sensors,
sitting in the front passenger seat
improperly out of position or with the
seatback reclined too far while the
vehicle is moving is dangerous as it
can take off weight from the seat
bottom and affect the weight
determination of the front passenger
sensing system. As a result the front
passenger will not have the
supplementary protection of the air
bag and seat belt pretensioner, which
could cause result in serious injury.
Always sit upright against your
seatback, with your feet on the floor.
Do not drive with the seatback
unlocked:
The seatback plays an important role
in your protection in a vehicle.
Leaving the seatback unlocked is
dangerous as it can allow passengers
to be ejected or thrown around and
baggage to strike occupants in a
sudden stop or collision, resulting in
severe injury. After adjusting the
seatback at any time, even when
there are no other passengers, rock
the seatback to make sure it is locked
in place.To change the seatback angle, lean
forward slightly while raising the lever.
Then lean back to the desired position and
release the lever.
Make sure the lever returns to its original
position and the seatback is locked in
place by attempting to push it forward and
backward.
CAUTION
When returning a rear-reclined
seatback to its upright position,
make sure you hold onto the
seatback with your other hand while
operating the lever. If the seatback is
not supported, it will flip forward
suddenly and could cause injury.

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:
In moderate or severe frontal or near-
frontal accidents, the front air bag and
pretensioner systems deploy
simultaneously. The front seat belt
retractors remove slack quickly as the air
bags are expanding.
In addition, the pretensioner system for
the front passenger, like the front
passenger air bag, is designed to only
deploy in accordance with the total seated
weight on the front passenger seat. Any
time the air bags and seat belt
pretensioners have fired they must be
replaced. For details, refer to the front
passenger seat weight sensors (page 2-47).
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 2-14).

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 come with the individual
child-restraint system.
A child who has outgrown child-restraint systems should sit in the rear and 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 buckle 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 shouldNEVERbe 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.
To reduce the chance of injuries caused by deployment of the front passenger air bag, the
front passenger seat weight sensors work 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 total seated weight on the front passenger
seat is less than approximately 30 kg (66 lb).
When an infant or small child sits on the front passenger seat, the system 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 properly secured on the rear
seats which are the best place for children.
For more details, refer to“Front passenger seat weight sensors”(page 2-47).

Seating a child in a child-restraint system on the front passenger seat is dangerous:
Vehicles equipped with front passenger seat weight sensors are also equipped with a
front passenger air bag deactivation indicator light (page 2-33). Even with the front
passenger seat weight sensors, if you must use the front passenger seat for children,
seating a child in 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.
ØThe total seated weight of the child with the child-restraint system on the front
passenger seat is approximately 30 kg (66 lb) or more with a child in the child-
restraint system.
ØLuggage or other items are placed on the seat with the child in the child-restraint
system.
ØA rear passenger or luggage push or pull down on the front passenger seatback.
ØA rear passenger puts their feet on the front seat rails.
ØLuggage or other items are placed on the seatback or hung on the head restraint.
ØThe seat is washed.
ØLiquids are spilled on the seat.
ØThe front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
ØThe front passenger seatback contacts the rear seat.
ØLuggage or other items are placed between the front passenger seat and driver
seat.
ØAny accessories, which might increase the total seated weight on the front
passenger seat, are attached to 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.
Do not allow a child 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. If the vehicle is equipped with side and curtain air bags, the impact of
inflation could cause serious injury or death to the 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. Do not allow a child to lean over or against the side window, even if the
child is seated in a child-restraint system.

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.
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.
Even if your vehicle is equipped with
front passenger seat weight sensors (page
2-47), 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 also employ
specially designed LATCH attachments;
refer to“LATCH Child-Restraint
Systems”(page 2-35).
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 benefit of being
tethered.
Place tether equipped child-restraint
systems where there are tether
anchors.
qRear Seat Child-Restraint System
Installation
Follow these instructions when using a
child-restraint system, unless you are
attaching a LATCH-equipped child-
restraint system to the rear LATCH lower
anchors. Refer to“LATCH Child-
Restraint Systems”(page 2-35).
NOTE
Follow the child-restraint system
manufacturer's instructions carefully. If you
are not sure whether you have a LATCH
system or tether, check in the child-restraint
system manufacturer's instructions and follow
them accordingly. Depending on the type of
child-restraint system, it may not employ seat
belts which are in automatic locking mode.
1. Make sure the seatback is securely
latched by pushing it back until it is
fully locked.
2. Secure the child-restraint system with
the lap portion of the lap/shoulder belt.
See the manufacturer's instructions on
the child-restraint system for belt
routing instructions.
3. To get the retractor into the automatic
locking mode, pull the shoulder belt
portion of the seat belt until the entire
length of the belt is out of the retractor.

qIf 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, even
with a seat weight sensor equipped
vehicle.
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.
Don't allow anyone to sleep against the
side window if you have an optional side
and curtain air bag, 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
lTo 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.
lTo 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.
WARNING
Always move the front passenger seat
as far back as possible if installing a
front-facing child-restraint system on it
is unavoidable:
As your vehicle has front air bags
and doubly so if your vehicle has side
air bags, a front-facing child-
restraint system should be put on the
front passenger seat only when it is
unavoidable.
Even if the front passenger air bag
deactivation indicator light
illuminates, always move the seat as
far back as possible, because the
force of a deploying air bag could
cause serious injury or death to the
child.
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 in a moderate collision, 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.
Even though you may feel assured
that the front passenger air bag will
not deploy based on the fact that the
front passenger air bag deactivation
indicator light illuminates.

Do not touch the components of the supplemental restraint system after the air bags
have inflated:
Touching the components of the supplemental restraint system after the air bags
have inflated is dangerous. Immediately after inflation, 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 affected. This could cause air bags to inflate
unexpectedly, or it could prevent the air bags from inflating 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 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 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.
