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

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.

LATCH Child-Restraint Systems
Your Mazda is equipped with LATCH lower anchors for attachment of specially designed
LATCH child-restraint systems in the rear seat. 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.

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: 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.

qLATCH Child-Restraint System
Installation Procedure (Rear
Center Seat)
The LATCH lower anchors at the center
of the rear seat are much further apart than
the sets of LATCH lower anchors for
child-restraint system installation at other
seating positions. Child-restraint systems
with rigid LATCH attachments cannot be
installed on the center seating position.
Some LATCH equipped child-restraint
systems can be placed in the center
position and will reach the nearest
LATCH lower anchors which are 400 mm
(15.75 in) apart. LATCH 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 LATCH lower anchors that are
400 mm (15.75 in) apart. Do not attach
two child-restraint systems to the same
LATCH lower anchor. If your child-
restraint system has a tether, it must also
be used for your child's optimum safety.
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 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.
1. Make sure the seatback is securely latched by pushing it back until it is
fully locked.
2. 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 LATCH lower
anchors for the attachment of a child-restraint
system.

If your vehicle is also equipped with a driver and front passenger occupant
classification system, refer to the Driver and Front Passenger Occupant Classification
System (page 2-57) for details.
If your vehicle is equipped with a driver and 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 2-26).
Carefully consider which child-restraint system is necessary for your child 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, side
collisions 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. Even if the front
passenger air bag deactivation indicator light illuminates, always move the front
passenger seat as far back as possible. A sleeping child is more likely to lean against
the door and be hit by the side air bag in a moderate collision to the front-passenger
side of the vehicle. Whenever possible, always secure a child 12 years and under on
the rear seat with an appropriate child-restraint system for the child's age and size.

Do not increase the total seated weight on the front passenger seat:When an infant or small child sits on the front passenger seat, increasing the total
seated weight on the front passenger seat is dangerous. The front passenger seat
weight sensors will detect the increased total seated weight, which could result in the
unexpected deployment of the front passenger front and side air bags and seat belt
pretensioner system in an accident and may cause serious injury. Increasing the total
seated weight on the front passenger seat could result in the front passenger front
and side air bags and seat belt pretensioner system deployment in an accident under
the following conditions, for example:
ØLuggage or other items are placed on the seat with the child in the child-restraint
system.
Ø A rear passenger or luggage push or pull down on the front passenger seatback.
Ø A rear passenger steps on the front passenger seat rails with their feet.
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 front passenger front and side air bags and seat belt pretensioner systems will
deactivate if the front passenger air bag deactivation indicator light illuminates.
CAUTION
Ø To assure proper deployment of the front air bag and to prevent damage to the
sensors in the front seat bottoms:
ØDo not place sharp objects on the front seat bottoms or leave heavy luggage on
them.
ØDo not spill any liquids on the front seats or under the front seats.
Ø To allow the sensors to function properly, always perform the following:
ØAdjust the front seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.
ØIf you place your child on the front passenger seat, secure the child-restraint
system properly and slide the front passenger seat as far back as possible (page
2-36).

lThe front passenger air bag deactivation indicator light may illuminate repeatedly if luggage or
other items are put on the front passenger seat, or if the temperature of the vehicle's interior
changes suddenly.
lThe front passenger air bag deactivation indicator light may illuminate for 10 seconds if the total
seated weight on the front passenger seat changes.
lThe air bag/front seat belt pretensioner system warning light might illuminate if the front
passenger seat receives a severe impact.
lIf the front passenger air bag deactivation indicator light does not illuminate after installing a
child-restraint system on the front passenger seat, first, re-install your child-restraint system
according to the procedure in this owner's manual. Then, if the front passenger air bag
deactivation indicator light still does not illuminate, install the child-restraint system on the rear
seat and consult an Authorized Mazda Dealer as soon as possible.
lIf the front passenger air bag deactivation indicator light illuminates when an adult is seated in
the front passenger seat, have the passenger re-adjust their posture by sitting with their feet on the
floor, and then re-fastening the seat belt. If the front passenger air bag deactivation indicator light
still illuminates, move the passenger to the rear seat. If sitting in the rear seat is not possible, slide
the front passenger seat as far back as possible.
qDriver and Front Passenger Buckle Switches
