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
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.

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.
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 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 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.

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.

Child-Restraint
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. Raise the head restraint to the top
locked position.
Refer to Head Restraints on page
2-11.
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.

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 2-56) 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.

Essential Safety Equipment
SRS Air Bags
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:
 Luggage or other items are placed on the seat with the child in the child-restraint
system. A rear passenger or luggage push or pull down on the front passenger seatback. A rear passenger steps on the front passenger seat rails with their feet. Luggage or other items are placed on the seatback or hung on the head restraint. Heavy items are placed in the seatback map pocket. The seat is washed. Liquids are spilled on the seat. The front passenger seat is moved backward, pushing into luggage or other items
placed behind it. The front passenger seatback contacts the rear seat. Luggage or other items are placed between the front passenger seat and driver seat. Any accessories which might increase the total seated weight on the front passenger
seat are attached to the front passenger seat.
CAUTION
 To assure proper deployment of the front air bag and to prevent damage to the sensors in
the front seat bottoms:
 Do not place sharp objects on the front seat bottoms or leave heavy luggage on them. Do not spill any liquids on the front seats or under the front seats.
 To allow the sensors to function properly, always perform the following:
 Adjust the front seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly. If 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 2-30).

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 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, always verify
that they are securely closed:
Doors not securely closed are
dangerous, if the vehicle is driven with
a door not securely closed, the door
could open unexpectedly resulting in
an accident.
Always confirm the safety around the
vehicle before opening a door: Suddenly opening a door 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 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 or a passing pedestrian could
be hit, resulting in an unexpected
accident or injury.
