3. Remove the head restraint. However,when installing a backless booster seat,
always install the vehicle head restraint
to the seat where the backless booster
seat is installed.
4. Place the child-res traint system on the

locking mode, pull the shoulder belt
portion of the seat belt until the entire
length of the belt is out of the retractor.
6. Push the child-restraint system firmly into the vehicle seat. Be sure the belt
retracts as snugly as possible. A

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-restraint system, it may not
employ seat belts which are in
automatic locking mode.
7. Seat your child safely in the
child-restraint system and secure the
child according to the instructions

▼(Mexico) Using ISOFIX Lower Anchor (Second-row Seats)/(Except M
exico) Using
LATCH Lower Anchor ( Second-row Seats)
Your Mazda is equipped with ISOFIX/LATCH*1 lower anchors for attachment of specially
designed ISOFIX/LATCH
*1 child-restraint systems in the second-row seats. Both anchors
must be used, otherwise the seat will bounce around and put the child in danger. Most
ISOFIX/LATCH
*1 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.
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 inju ry 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 fa sten it with a seat belt, or attach it to BOTH
ISOFIX/LATCH
*1 lower anchors for ISOFIX/LATCH*1 child-restraint systems.

If your vehicle is also equipped with a front passenger occupant classification system,
refer to the Front Passenger O ccupant Classification System (pa ge 2-84) for details.
If your vehicle is equipped with a front passenger occupant cla ssification 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 chi ldren must use a child-restraint
system (page 2-44).

Carefully consider whic h child-restraint system is necessary fo r your child and follow the
installation directions in this Owner's Manual as well as the c hild-restraint system
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 occu pants 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 ba g 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-restrain t system for the child's age and size.

WA R N I N G
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
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,
always verify that they are securely closed:
Doors and the liftgate not securely closed
are dangerous, if the vehicle is driven with
a door and the liftgate not securely closed,
the door and the liftgate could open
unexpectedly resulting in an accident.
Always confirm the safety around the
vehicle before opening a door and the
liftgate:
Suddenly opening a door and the liftgate 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 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 or a
passing pedestrian could be hit, resulting
in an unexpected accident or injury.
NOTE
Always stop the engine and lock the
doors. In addition, to prevent theft of
valuables, do not leave them inside the
cabin.
If the key is left in the following areas
and you leave the vehicle, the doors may
be locked depending on the radio wave
conditions even if th e key is left in the
vehicle.
