Seat Precautions
▼Seat Precautions
WARNING
Make sure the adjustable components
of a seat are locked in place:
Adjustable seats and seatbacks that are
not securely locked are dangerous. In a
sudden stop or collision, the seat or
seatback could move, causing injury.
Make sure the adjustable components
of the seat are locked in place by
attempting to slide the seat forward
and backward and rocking the
seatback.
Never allow children to adjust a seat:
Allowing children to adjust a seat is
dangerous as it could result in serious
injury if a child's hands or feet become
caught in the seat.
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.
Adjust a seat only when the vehicle is
stopped:
If the seat is adjusted while the vehicle
is being driven, the seating posture
may become unstable and the seat
could move unexpectedly resulting in
injury.
Do not modify or replace the front
seats:
Modifying or replacing the front seats
such as replacing the upholstery or
loosening any bolts is dangerous. The
front seats contain air bag components
essential to the supplemental restraint
system. Such modi
fications could
damage the supplemental restraint
system and result in serious injury.
Consult an Authorized Mazda Dealer if
there is any need to remove or reinstall
the front seats.
Do not drive with damaged front
seats:
Driving with damaged front seats, such
as seat cushions torn or damaged
down to the urethane, is dangerous. A
collision, even one not strong enough
to in flate the air bags, could damage
the front seats which contain essential
air bag components. If there was a
subsequent collision, an air bag may
not deploy which could lead to
injuries. Always have an Authorized
Mazda Dealer inspect the front seats,
front seat belt pretensioners and air
bags after a collision.

Rear Seat
▼Split Folding the Seatbacks
By lowering the rear seatbacks the
luggage compartment space can be
expanded.
WARNING
Do not drive the vehicle with
occupants on folded down seatbacks
or in the luggage compartment.
Putting occupants in the luggage
compartment is dangerous because
seat belts cannot be fastened which
could lead to serious injury or death
during sudden braking or a collision.
Do not allow children to play inside
the vehicle with the seatbacks
lowered.
Allowing children to play in the vehicle
with the seatbacks folded down is
dangerous. If a child enters the luggage
compartment and the seatbacks were
raised back up, the child may become
trapped in the luggage compartment
which could lead to an accident.
Tightly secure cargo in the luggage
compartment when it is transported
with the seatbacks folded down.
Driving without tightly securing cargo
and luggage is dangerous as it could
move and become an obstruction to
driving during emergency braking or a
collision resulting in an unexpected
accident.
When transporting cargo, do not
allow the cargo to exceed the height
of the seatbacks.
Transporting cargo stacked higher than
the seatbacks is dangerous as visibility
to the rear and sides of the vehicle is
reduced which could interfere with
driving operations and lead to an
accident.
Lowering the seatbacks
CAUTION

(5–Door)
When folding the seatback forward,
always support the seatback with
your hand. If it is not supported by a
hand, fingers or the hand pressing
the push knob could be injured.
 Check the position of a front seat
before folding a rear seatback.
Depending on the position of a front
seat, it may not be possible to fold a
rear seatback all the way down
because it may hit the seatback of
the front seat which could scratch or
damage the front seat or its pocket.
Lower or remove the head restraint
on the rear outboard seat if
necessary.

WARNING
Never put your hands and fingers
around the moving parts of the seat
and armrest:
Putting your hands and fingers around
the moving parts of the seat and
armrest is dangerous as they could get
injured.
Head Restraints
▼ Head Restraints
Your vehicle is equipped with head
restraints on all outboard seats and the
rear center seat. The head restraints are
intended to help protect you and the
passengers from neck injury.
WARNING
Always drive with the head restraints
installed when seats are being used
and make sure they are properly
adjusted:
Driving with the head restraints
adjusted too low or removed is
dangerous. With no support behind
your head, your neck could be
seriously injured in a collision.
▼
Height Adjustment
Adjust the head restraint so that the
center is even with the top of the
passenger's ears.

To raise a head restraint, pull it up to
the desired position.
To lower the head restraint, press the
stop-catch release, then push the head
restraint down.

Driving with the head restraints not
installed is dangerous. With no support
behind your head, your neck could be
seriously injured in a collision.
After installing a head restraint, try
lifting it to make sure that it does not
pull out:
Driving with an unsecured head
restraint is dangerous as the
e
ff ectiveness of the head restraint will
be compromised which could cause it
to unexpectedly detach from the seat.

Seat Belt Precautions
▼Seat Belt Precautions
Seat belts help to decrease the
possibility of severe injury during
accidents and sudden stops. Mazda
recommends that the driver and all
passengers always wear seat belts.

(Mexico)
All the seats have lap/shoulder belts.
These belts have retractors with inertia
locks that keep them out of the way
when not in use. The locks allow the
belts to remain comfortable on users,
but they will lock in position during a
collision.

(Except Mexico)
All of the seat belt retractors are
designed to keep the lap/shoulder
belts out of the way when not in use.
The driver's seat belt has no provisions
for child-restraint systems and has only
an emergency locking mode. The
driver may wear it comfortably, and it
will lock during a collision.
However, the front passenger's seat
and all rear lap/shoulder belt
retractors operate in two modes:
emergency locking mode, and for
child-restraint systems, automatic
locking mode. While we recommend
you put all children in the rear seats, if
you must use the front passenger seat
for a child, slide the front passenger
seat as far back as possible and make
sure any child-restraint system is
secured properly.
WARNING
Always wear your seat belt and make
sure all occupants are properly
restrained:
Not wearing a seat belt is extremely
dangerous. During a collision,
occupants not wearing seat belts could
hit someone or things inside the
vehicle or even be thrown out of the
vehicle. They could be seriously injured
or even killed. In the same collision,
occupants wearing seat belts would be
much safer.
Do not wear twisted seat belts:
Twisted seat belts are dangerous. In a
collision, the full width of the belt is
not available to absorb the impact.
This puts more force on the bones
beneath the belt, which could cause
serious injury or death. So, if your seat
belt is twisted, you must straighten the
seat belt to remove any twists and to
allow the full width of the belt to be
used.
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.

Installing Child-RestraintSystems
▼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 occupant classi
fication
sensor (page 2-71), 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 e ffective. 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 ISOFIX/
LATCH
*1 attachments; refer to "Using
ISOFIX Lower Anchor (Mexico)/Using
LATCH Lower Anchor (Except
Mexico)" (page 2-50).
*1 ISOFIX (Mexico)/LATCH (Except Mexico)
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.
▼ Anchor Bracket
Anchor brackets for securing
child-restraint systems are equipped in
the vehicle. Locate each anchor
position using the illustration.
To install a child-restraint system,
remove the head restraint. Always
follow the instruction manual
accompanying the child-restraint
system.

Anchor bracket location
Use the indicated anchor bracket
locations when installing a
child-restraint system equipped with a
tether.

Do not allow a child or anyone to
lean over to or against the side
window of a vehicle with side and
curtain air bags:
It is dangerous to allow anyone to lean
over to 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 to or
against the front door could block the
side and curtain air bags and eliminate
the advantages of supplemental
protection. Because the front seats are
equipped with fron t air bags, the rear
seat is always a better location for
children. Take special care not to allow
a child to lean over to or against the
side window, even if the child is seated
in a child-restraint system.
Always remove the head restraint and
install child-restraint system (except
when installing a backless booster
seat):
Installing a child-restraint system
without removing the head restraint is
dangerous. The child-restraint system
cannot be installed correctly which
may result in death or injury to the
child in a collision.Always install the head restraint and
adjust it to the appropriate position
after removing the child-restraint
system:
Driving with the head restraint
removed is dangerous as impact to the
occupant's head cannot be prevented
during emergency braking or in a
collision, which could result in a
serious accident, injury or death.
Refer to Head Restraints on page 2-17.

Never attach two child-restraint
systems to the same ISOFIX/LATCH*1
lower anchor:
Attaching two child-restraint systems
to the same ISOFIX/LATCH
*1 lower
anchor is dangerous. In a collision, one
anchor may not be strong enough to
hold two child-restraint system
attachments, and it may break, causing
serious injury or death. If you use the
seat position for another child-restraint
system when an outboard ISOFIX/
LATCH
*1 position is occupied, use the
center seat belts instead, and the
tether if tether-equipped.
Make sure the child-restraint system is
properly secured:
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. Follow the child-restraint
system manufacturer's instructions on
belt routing to secure the seat just as
you would with a child in it so that
nobody is tempted to put a child in an
improperly secured seat later on.
When not in use, remove it from the
vehicle or fasten it with a seat belt, or
attach it to BOTH ISOFIX/LATCH
*1
lower anchors for ISOFIX/LATCH*1
child-restraint systems.
Make sure there are no seat belts or
foreign objects near or around the
ISOFIX/LATCH
*1 child-restraint
system:
Not following the child-restraint system
manufacturer's instructions when
installing the child-restraint system is
dangerous. If seat belts or a foreign
object prevent the child-restraint
system from being securely attached to
the ISOFIX/LATCH
*1 lower anchors
and the child-restraint system is
installed improperly, the child-restraint
system could move in a sudden stop or
collision causing serious injury or death
to the child or other occupants. When
installing the child-restraint system,
make sure there are no seat belts or
foreign objects near or around the
ISOFIX/LATCH
*1 lower anchors.
Always follow the child-restraint
system manufacturer's instructions.
*1ISOFIX (Mexico)/LATCH (Except Mexico)
Installation on rear outboard seats
1. First, adjust the front seat to allow clearance between the
child-restraint system and the front
seat.
Refer to Adjusting the Driver's Seat
on page 2-5.
Refer to Adjusting the Front
Passenger's Seat on page 2-13.
2. Make sure the seatback is securely latched by pushing it back until it is
fully locked.

3. Forward

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.
Always install the head restraint and
adjust it to the appropriate position
after removing the child-restraint
system:
Driving with the head restraint
removed is dangerous as impact to the
occupant's head cannot be prevented
during emergency braking or in a
collision, which could result in a
serious accident, injury or death.
Refer to Head Restraints on page 2-17.

Installation on rear center seat
The ISOFIX/LATCH*1 lower anchors at
the center of the rear seat are much
further apart than the sets of ISOFIX/
LATCH
*1 lower anchors for
child-restraint system installation at
other seating positions. Child-restraint
systems with rigid ISOFIX/LATCH
*1
attachments cannot be installed on the
center seating position. Some ISOFIX/
LATCH
*1 equipped child-restraint
systems can be placed in the center
position and will reach the nearest
ISOFIX/LATCH
*1 lower anchors which
are 434 mm (17.1 in) apart. ISOFIX/
LATCH
*1 compatible child-restraint
systems (with attachments on belt
webbing) can be used at this seating
position only if the child-restraint
system manufacturer's instructions
state that the child-restraint system can
be installed to ISOFIX/LATCH
*1 lower
anchors that are 434 mm (17.1 in)
apart. Do not attach two child-restraint
systems to the same ISOFIX/LATCH
*1
lower anchor. If your child-restraint
system has a tether, it must also be
used for your child's optimum safety.

The procedure is the same as the
installation for the rear outboard seats.

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 si de 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 norm ally 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 modi fications 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, and
that the front passenger occupant
classi fication system and the seats
retain an undamaged air bag
connection.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 operate a vehicle with
damaged air bag/seat belt
pretensioner system components:
Expended or damaged air bag/seat
belt pretensioner system components
must be replaced after any collision
which caused them to deploy or
damage them. Only a trained
Authorized Mazda Dealer can fully
evaluate these systems to see that they
will work in any subsequent accident.
Driving with an expended or damaged
air bag or pretensioner unit will not
a ff ord you the necessary protection in
the event of any subsequent accident
which could result in serious injury or
death.
Do not remove interior air bag parts:
Removing any components such as the
front seats, front dashboard, the
steering wheel or pa rts on the front
and rear window pillars and along the
roof edge, containing air bag parts or
sensors is dangerous. These parts
contain essential air bag components.
The air bag could accidentally activate
and cause serious injuries. Always have
an Authorized Mazda Dealer remove
these parts.
