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 the automatic locking mode. If the
belt does not lock the seat down tight,
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.
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

Essential Safety Equipment
Child-Restraint
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
2-12.
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 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 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
 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.
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 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.

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
 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.
 Follow the child-restraint system
manufacturer's instructions carefully.
Depending on the type of child-r estraint
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. 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 ignition to OFF, and
then re-install the child-restraint system
(page
2-57).

Essential Safety Equipment
Child-Restraint
Using LATCH Lower Anchor
Your Mazda is equipped with LATCH lower anchors for attachment of specially designed
LATCH 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 LATCH child-restraint systems
must also be used in conjunction with a tether to be effective. If they have a tether you must
use it to better assure your child's safety.
WARNING
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 LATCH lower anchor: Attaching two child-restraint systems to the same LATCH 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 LATCH 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
latch it down to BOTH LATCH lower anchors for LATCH child-restraint systems.
Make sure there are no seat belts or foreign objects near or around the LATCH 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 LATCH 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 LATCH lower anchors. Always follow the child-restraint system
manufacturer's instructions.

Installation on rear outboard seats
1. First, adjust the front seat to allow
clearance between the child-restraint
system and the front seat (page
2-5).
2. Make sure the seatback is securely
latched by pushing it back until it is
fully locked.
3. Expand the area between the seat
bottom and the seatback slightly to
verify the locations of the LATCH
lower anchors.

NOTE
The markings above the LATCH lower
anchors indicate the locations of the
LATCH lower anchors for the attachment
of a child-restraint system.
4. Remove the head restraint.
Refer to Head Restraints on page
2-12.
5. Secure the child-restraint system
using BOTH LATCH lower anchors,
following the child-restraint system
manufacturer's instruction. Pull on the
child-restraint to be sure both anchors
are engaged.
6. If your child-restraint system came
equipped with a tether, that means it is
very important to properly secure the
tether for child safety. Please carefully
follow the child-restraint system
manufacturer's instructions when
installing tethers.
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 remove the head restraint and
set the tether strap: 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.

Essential Safety Equipment
SRS Air Bags
If your vehicle is also equipped with a front passenger occupant classification system,
refer to the Front Passenger Occupant Classification System (page
2-57) 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 stipulat\
ed by law in every
state and province. In certain states and provinces, larger children must use a child-restraint
system (page
2-22).
Carefully consider which child-restraint system is necessary for your ch\
ild and follow
the installation directions in this Owner's Manual as well as the child-\
restraint system
manufacturer's instructions.
WARNING
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.

WARNING
Always take all children and pets with
you or leave a responsible person with
them:Leaving a child or a pet unattended in
a parked vehicle is dangerous. In hot
weather, temperatures inside a vehicle
can become high enough to cause
brain damage or even death.
Do not leave the key in your vehicle with
children and keep them in a place where
your children will not find or play with
them: Leaving children in a vehicle with the
key is dangerous. This could result in
someone being badly injured or even
killed.
Keep all doors locked when driving: Unlocked doors in a moving vehicle
are dangerous. Passengers can fall out
if a door is accidentally opened and
can more easily be thrown out in an
accident.
Always close all the windows and
moonroof, lock the doors and the
liftgate/trunk lid and take the key
with you when leaving your vehicle
unattended: Leaving your vehicle unlocked is
dangerous as children could lock
themselves in a hot vehicle, which
could result in death. Also, a vehicle left
unlocked becomes an easy target for
thieves and intruders. After closing the doors and the liftgate/
trunk lid, always verify that they are
securely closed:
Doors and the liftgate/trunk lid not
securely closed are dangerous, if the
vehicle is driven with a door and the
liftgate/trunk lid not securely closed,
the door and the liftgate/trunk lid
could open unexpectedly resulting in
an accident.
Always confirm the safety around the
vehicle before opening a door and the
liftgate/trunk lid: Suddenly opening a door and the
liftgate/trunk lid is dangerous. A
passing vehicle or a pedestrian could
be hit and cause an accident.
CAUTION
Always confirm the conditions around
the vehicle before opening/closing the
doors and the liftgate/trunk lid and use
caution during strong winds or when
parked on an incline. Not being aware
of the conditions around the vehicle is
dangerous because fingers could get
caught in the door and the liftgate/
trunk lid or a passing pedestrian could
be hit, resulting in an unexpected
accident or injury.
