Make sure the lever returns to its original
position and the seat is locked in place by
attempting to push it forward and
backward.
qSeat Recline
WARNING
Do not drive with either front seat
reclined:
Sitting in a reclined position while the
vehicle is moving is dangerous
because you do not get the full
protection from seat belts. During
sudden braking or a collision, you
can slide under the lap belt and
suffer serious internal injuries. For
maximum protection, sit well back
and upright.
Always sit in the front passenger seat
properly with the seatback upright and
feet on the floor (With Driver and Front
Passenger Occupant Classification
System): Your front passenger seat has 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 result in serious injury. Always
sit upright against the seatback with
your feet on the floor. Do not drive with the seatback
unlocked:
All of the seatbacks play 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.

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. Any time the air bags
and front seat belt pretensioners have
deployed they must be replaced.
(With Driver and Front Passenger
Occupant Classification System)
During a side collision, the side air bag,
curtain air bag, and pretensioner system
operate simultaneously on the side in
which the collision occurs.
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
sufficient occupant movement.
Even if the pretensioners have not
deployed, the load limiting function must
be checked by an Authorized Mazda
Dealer after any collision.
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 2-18).

Seat Belt Reminder
NOTE
Consult an Authorized Mazda Dealer to
deactivate or restore the belt reminder. Though
the belt reminder can be deactivated, doing so
will defeat the purpose of the system to warn
the driver and the front passenger in the event
that their seat belts are not fastened. For the
safety of the driver and front passenger, Mazda
recommends not deactivating the belt
reminder.
If the vehicle is driven with the driver or
front passenger's seat belt unfastened, the
seat belt warning light illuminates and a
warning chime sounds.
NOTE
Some models do not have the seat belt
reminder function for the front passenger's
seat.
If the driver or front passenger's seat belt
is unfastened (only when the front
passenger seat is occupied) and the
vehicle is driven at a speed faster than
about 20 km/h (12 mph), the warning
light will flash and a beep sound will be
heard. After a short time, the warning
light stops flashing, but remains
illuminated, and the beep sound stops.
Until a seat belt is fastened or a given
period of time has elapsed, the beep sound
will not stop even if the vehicle speed
falls below 20 km/h (12 mph).NOTE
lThe warning light flashes and a beep sound
will be heard for about 6 seconds if the
driver's seat belt is not fastened when the
ignition is switched ON.
lIf a driver or front passenger's seat belt is
unfastened after the beep sound turns off
(warning light remains illuminated), and
the vehicle speed exceeds 20 km/h (12
mph), the warning light flashes and beep
sound activates again.
lPlacing heavy items on the front passenger
seat may cause the front passenger seat belt
warning function to operate depending on
the weight of the item.
lTo allow the front passenger seat weight
sensor to function properly, do not place
and sit on an additional seat cushion on the
front passenger seat. The sensor may not
function properly because the additional
seat cushion could cause sensor
interference.
lWhen a small child sits on the front
passenger seat, it is possible that the
warning light will not operate.

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.
(With Driver and Front Passenger Occupant Classification System)
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 front passenger air bag deactivation
indicator light illuminates.
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 2-57).

Seating a child in a child-restraint system on the front passenger seat is dangerous
under certain conditions (With Driver and Front Passenger Occupant Classification
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.
ØThe front passenger air bag deactivation indicator light does not illuminate when
seating a child in the child-restraint system.
Ø Luggage or other items are placed on the seat with the child in the child-restraint
system.
Ø A rear passenger or luggage pushing or pulling down on the front passenger
seatback.
Ø A rear passenger puts their feet on the front seat rails.
Ø Luggage or other items are placed on the seatback or hung on the head restraint.
Ø Heavy items are placed in the seatback map pocket.
Ø The seat is washed.
Ø Liquids are spilled on the seat.
Ø The front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
Ø The front passenger seatback contacts the rear seat.
Ø Luggage or other items are placed between the front passenger seat and driver
seat.
Ø Any 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 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.

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“LATCH Child-Restraint
Systems ”(page 2-39).
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 2-39).
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 use LATCH
system instead of seat belts or if the belt goes
across the child's chest, may recommend
against using automatic locking mode.
1. Make sure the seatback is securely latched by pushing it back until it is
fully locked.

WARNING
Use the tether and tether anchor only
for a child-restraint system:Using the tether or tether anchor to
secure anything but a child-restraint
system is dangerous. This could
weaken or damage the tether or
tether anchor and result in injury.
Always route the tether strap between
the head restraint and the seatback (4
Door): Routing the tether strap on top of the
head restraint is dangerous. In a
collision the tether strap could slide
off the head restraint and loosen the
child-restraint system. The child-
restraint system could move which
may result in death or injury to the
child.
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.
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
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 if you have optional 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
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.

3. Place the child-restraint system on theseat without putting your weight on the
seat and fasten the seat belt. See the
manufacturer's instructions on the
child-restraint system for belt routing
instructions.
4. 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.
5. Push the child-restraint system firmly into the vehicle seat. Be sure the belt
retracts as snugly as possible. A
clicking noise from the retractor will be
heard during retraction if the system is
in automatic locking mode. If the belt
does not lock the seat down tight,
repeat the previous step and also this
one.
NOTE
lInspect this function before each use of the
child-restraint system. You should not be
able to pull the shoulder belt out of the
retractor while the system is in the
automatic locking mode. When you remove
the child-restraint system, be sure the belt
fully retracts to return the system to
emergency locking mode before occupants
use the seat belts.
lFollow the child-restraint system
manufacturer's instructions carefully.
Depending on the type of child-restraint
system, it may not employ seat belts which
are in automatic locking mode.
6. Seat your child safely in the child- restraint system and secure the child
according to the instructions from the
child-restraint system manufacturer. 7.
(With Driver and Front Passenger
Occupant Classification System)
Make sure the front passenger air bag
deactivation indicator light illuminates
after installing a child-restraint system
on the front passenger seat.
If the front passenger air bag
deactivation indicator light does not
illuminate, remove the child-restraint
system, switch the ignition to OFF or
ACC, and then re-install the child-
restraint system.

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 inflates 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 inflates 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.
Do not place luggage or other objects under the front seats: Placing luggage or other objects under the front seats is dangerous. The components
essential to the supplemental restraint system could be damaged, and in the event of
a side collision, the appropriate air bags may not deploy, which could result in death
or serious injury. To prevent damage to the components essential to the
supplemental restraint system, do not place luggage or other objects under the front
seats.
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 a front door or leave any damage unrepaired. Always have an
Authorized Mazda Dealer inspect a damaged front door: Modifying a front door or leaving any damage unrepaired is dangerous. Each front
door has a side crash sensor as a component of the supplemental restraint system. If
holes are drilled in a front door, a door speaker is left removed, or a damaged door is
left unrepaired, the sensor could be adversely affected causing it to not detect the
pressure of an impact correctly during a side collision. If a sensor does not detect a
side impact correctly, the side and curtain air bags and the front seat belt
pretensioner may not operate normally which could result in serious injury to
occupants.
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.
lOn some models, a highly-visible label is displayed which warns against the use of rear-facing
child-restraint systems on the front passenger seat.
