4. To get the retractor into the automaticlocking 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 firmlyinto 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 the automatic locking mode. If the

repeat this step.
NOTE
Inspect 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.
6. If your child-restraint system requires the use of a tether strap, refer to the
manufacturer's instructions to hook
and tighten the tether strap.
WA R N I N G

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 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.

▼If You Must Use th
e 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 shou lder belt over the
shoulder.
NEVER put a rear-fac ing child-restraint
system on the front passenger seat whether
your vehicle is equipped with an occupant
classification 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 ISOFIX/LATCH
*1
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.
*1 ISOFIX (Mexico)/LATCH (Except Mexico)
NOTE
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.
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.
WA R N I N G
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 because 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, you should not
use a rear-facing child-restraint system in
the front seat.

6. Push the child-restraint system firmlyinto 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
Inspect this function before each use
of the child-rest raint 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.
Follow the child- restraint system
manufacturer's instructions
carefully.
Depending on the type of
child-restraint sy stem, it may not
employ seat belts which are in
automatic locking mode.
7. Seat your child safely in the
child-restraint sy stem and secure the
child according to the instructions
from the child-restraint system
manufacturer.
8. Switch the ignition ON and 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 i gnition to OFF, and
then re-install th e child-restraint
system (page 2-72).

WA R N I N G
Do not seat a child in a child-restraint
system on the front passenger seat if the
front passenger air bag deactivation
indicator light does not illuminate:
While it is always better to install any
child-restraint system on the rear seat, it is
imperative that a child-restraint system
ONLY be used on the front passenger seat if
the deactivation indicator light illuminates
when the child is seated in the
child-restraint system (page 2-72). Seating
a child in a child-restraint system installed
on the front passenger seat with the front
passenger air bag deactivation indicator
light not illuminated is dangerous. If this
indicator light does not illuminate, this
means that the front passenger front and
side air bags, and knee air bags, and seat
belt pretensioners are ready for
deployment. If an accident were to deploy
an air bag, a child in a child-restraint
system sitting in the front passenger seat
could be seriously injured or killed. If the
indicator light does not illuminate after
seating a child in a child-restraint system
on the front passenger seat, seat a child in
a child-restraint system on the rear seat
and consult an Authorized Mazda Dealer
as soon as possible.
▼ Using ISOFIX Lower Anchor
(Mexico)/Using LATCH Lower
Anchor (Except Mexico)
Your Mazda is equipped with ISOFIX/
LATCH
*1 lower anchors for attachment of
specially designed ISOFIX/LATCH
*1
child-restraint systems in the rear seats.
Both anchors must be used, otherwise the
seat will bounce around and put the child
in danger. Most ISOFIX/LATCH
*1
child-restraint system s must also be used
in conjunction with a te ther to be effective.
If they have a tether you must use it to
better assure your child's safety.
WA R N I N G
Follow the manufacturer's instructions for
the use of the child-restraint system:
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
the child-restraint system is properly
secured in place according to the
child-restraint system manufacturer's
instructions.

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-re straint 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.
*1 ISOFIX (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

If your vehicle is also equipped with a
front passenger occupant classification
system, refer to the Front Passenger
Occupant Classification System (page
2-71) for details.
If your vehicle is equipped with a front
passenger occupant classification system,
the front passenger air bag deactivation
indicator light illuminates for a specified
time after the ignition is switched ON.


Small children must be protected by a
child-restraint system as stipulated by law
in every state and province. In certain
states and provinces, larger children must
use a child-restraint system (page 2-32).

Carefully consider wh ich child-restraint
system is necessary for your child and
follow the installation directions in this
Owner's Manual as well as the
child-restraint syst em manufacturer's
instructions.
WA R N I N G
Seat belts must be worn in air bag
equipped vehicles:
Depending only on the air bags for
protection during an accident is
dangerous. Alone, air bags may not
prevent serious injuries. The appropriate air
bags can be expected to inflate only in the
first accident, such as frontal, near frontal
or side collisions or roll-over accidents that
are at least moderate. Vehicle occupants
should always wear seat belts.

Children should not ride in the front
passenger seat:
Placing a child, 12 years or under, in the
front seat is dangerous. The child could be
hit by a deploying air bag and be seriously
injured or even killed. A sleeping child is
more likely to lean against the door and be
hit by the side air bag in moderate collision
to the front-passenger side of the vehicle.
Whenever possible, always secure a child
12 years and under on the rear seats with
an appropriate child-restraint system for
the child's age and size.
