▼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.
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 accordin g 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 inju ry or death. If you use the seat position for
another child-restraint system when an outboar d 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 routin g 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 manu facturer's instructions when installing the
child-restraint system is dangerous. If seat be lts 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-restr aint system could move in a sudden stop or
collision causing serious injury or death to th e 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 allowclearance 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 open seams on the rear of
the seat bottom slig htly 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. However,
when installing a backless booster seat,
always install the vehicle head restraint
to the seat where the backless booster
seat is installed.
Refer to Head Restra ints 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.
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 your vehicle is also equipped with a front passenger occupant classification system,
refer to the Front Passenger O ccupant Classification System (pa ge 2-61) 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 2-23).

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 appr opriate air bags can be expected to inflate
only in the first accident, such as frontal, near frontal or side collision s 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.

Door Locks
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.
