Installing Child-RestraintSystems
▼Installing Child-Restraint Systems
Accident statistics reveal that a child is
safer in the rear seat
. The front passenger's
seat is clearly the worst choice for any
child under 12, and with rear-facing
child-restraint system s it is clearly unsafe
due to air bags.

NOTE
Even if your vehicle is equipped with front
passenger occupant classification sensor
(page 2-72), which automatically
deactivates the front passenger air bag, a
rear seat is the safest place for a child of
any age or size.

Some child-restraint systems now come
with tethers and t herefore must be
installed on the seats that take tethers to be
effective. In your Mazda, tethered
child-restraint systems can only be
accommodated in the three positions on
the rear seat.

Some child-restraint systems also employ
specially designed ISOFIX/LATCH
*1
attachments; refer to "Using ISOFIX
Lower Anchor (Mexico)/Using LATCH
Lower Anchor (Except Mexico)" (page
2-50).
*1 ISOFIX (Mexico)/LATCH (Except Mexico)
WA R N I N G
Tethered Child-Restraint Systems Work
Only on Tether-Equipped Rear Seats:
Installation of a tether equipped
child-restraint system in the front
passenger's seat defeats the safety design
of the system and will result in an increased
chance of serious injury if the
child-restraint system goes forward
without benefit of being tethered.
Place tether equipped child-restraint
systems where there are tether anchors.
▼Anchor Bracket
Anchor brackets for securing
child-restraint systems are equipped in the
vehicle. Locate each anchor position using
the illustration.
To install a child-restraint system, remove
the head restraint. Always follow the
instruction manual accompanying the
child-restraint system.

Anchor bracket location
Use the indicated anchor bracket locations
when installing a ch
ild-restraint system
equipped with a tether.

WA R N I N G
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.
Always remove the head restraint and
install child-restraint system:
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.

Always install the head restraint and adjust
it to the appropriate position after

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 2-17.
▼Using Automatic Locking Mode
(Except Mexico)
Follow these instructions when using a
child-restraint system, unless you are
attaching a LATCH-equipped
child-restraint syst
em to the rear LATCH
lower anchors. Refer to “Using LATCH
Lower Anchor” (page 2-50).
NOTE
Follow the child- restraint system
manufacturer's instructions carefully. If
you are not sure whether you have a
LATCH system or tether, check in the
child-restraint syst em manufacturer's
instructions and follow them accordingly.
Depending on the type of child-restraint
system, it may use LATCH system instead
of seat belts or if the belt goes across the
child's chest, may recommend against
using automatic locking mode.
1. Make sure the seatback is securely latched by pushing it back until it is
fully locked.
2. 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 Restraints on page 2-17.
3. Secure the child-restraint system with the lap portion of the lap/shoulder belt.
See the manufacturer's instructions on
the child-restraint system for belt
routing instructions.

4. To get the retractor into the automaticlocking 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 firmlyinto 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.
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.
