Child-Restraint Precautions
Mazda strongly urges the use of child-restraint systems for children small enough to use
them.

You are required by law to use a child-restraint system for children in the U.S. and Canada.
Check your local and state or provincial laws for specific requirements regarding the safety
of children riding in your vehicle.

Whatever child-restraint system you consider, please pick the appropriate one for the age
and size of the child, obey the law and follow th e instructions that come with the individual
child-restraint system.

A child who has outgrown child-restraint systems should sit in the rear and use seat belts,
both lap and shoulder. If the shoulder belt crosses the neck or face, move the child closer to
the center of the vehicle in the outboard seats, and towards the buckle on the right if the
child is seated on the center seat.

Statistics confirm that the rear seat is the best place for all children up to 12 years of age,
and more so with a supplement al restraint system (air bags).

A rear-facing child-restraint system should NEVER be used on the front seat with the air
bag system activated. The front passenger's seat is also the least preferred seat for other
child-restraint systems.

(With Front Passenger Occupa nt Classification System)
To reduce the chance of injuries caused by de ployment of the front passenger air bag, the
front passenger occupant classification sensor works as a part of the supplemental restraint
system. This system deactivates the front passe nger front and side air bags and also the front
passenger seat belt pretensioner system when the front passenger air bag deactivation
indicator light illuminates.

When an infant or small child sits on the front passenger seat, the system shuts off the front
passenger front and side air bags and seat belt pretensioner system, so make sure the front
passenger air bag deactivation indicator light illuminates.

Even if the front passenger air bag is shut of f, Mazda strongly recommends that children be
properly restrained and child-restraint systems of all kinds are properly secured on the rear
seats which are the best place for children.

For more details, refer to "Front passenge r occupant classification sensor" (page 2-66).

WARNING
Use the correct size child-restraint system:
For effective protection in vehicle accidents and sudden stop s, a child must be properly
restrained using a seat belt or child-restraint system depending on age and size. If not, the
child could be seriously injured or even killed in an accident.
Follow the manufacturer's instructions and always keep the child-restraint system buckled
down:
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 any child-restraint
system is properly secured in place accordin g to the child-restraint system manufacturer's
instructions. When not in use, remove it from the vehicle or fasten it with a seat belt, or attach
it to BOTH ISOFIX/LATCH
*1 lower anchors for ISOFIX/LATCH*1 child-restraint systems and the
corresponding tether anchor.
*1 ISOFIX (Mexico)/LATCH (Except Mexico)
Always secure a child in a proper child-restraint system:
Holding a child in your arms while the vehicl e is moving is extremely dangerous. No matter
how strong the person may be, he or she cannot hold onto a child in a sudden stop or collision
and it could result in serious injury or death to the child or other occupants. Even in a
moderate accident, the child may be exposed to air bag forces that could result in serious
injury or death to the child, or the child may be slammed into an adult, causing injury to both
child and adult.
Never use a rear-facing child-restraint system in the front seat with an air bag that could
deploy:
Rear-facing child-restraint systems on the front seat are particularly dangerous even though
you may feel assured that a front passenger air bag will not deploy based on the fact that the
front passenger air bag deactivation indicato r light illuminates. The child-restraint system
can be hit by a deploying air bag and moved viol ently backward resulting in serious injury or
death to the child.

Vehicles with a front passenger air bag have the following warning label. The warning label
reminds you not to put a rear-facing child-restra int system on the front passenger seat at any
time.
(Mexico)
NEVER use a rearward facing child restraint on a seat protected by an ACTIVE AIRBAG in front
of it, DEATH or SERIOUS INJURY to the CHILD can occur.
Vehicles with a front passenger air bag have th e following warning label. The warning label
reminds you not to put a rear-facing child-restra int system on the front passenger seat at any
time.

Do not install a front-facing child-restraint system on the front passenger seat unless it is
unavoidable:
In a collision, the force of a deploying air bag co uld cause serious injury or death to the child. If
installing a front-facing child-restraint system on the front passenger seat is unavoidable,
move the front passenger seat as far back as possible and adjust the seat bottom (height
adjustable seat bottom) to the highest posi tion at which the seat belt fastening the
child-restraint system is securely tightened.

Never use one seat belt on more than one person at a time:
Using one seat belt for more than one person at a time is dangerous. A seat belt used in this
way cannot spread the impact forces properly and the two passengers could be crushed
together and seriously injured or even killed. Never use one belt for more than one person at a
time and always operate the vehicle with each occupant properly restrained.
CAUTION
A seat belt or child-restraint system can become very hot in a closed vehicle during warm
weather. To avoid burning yourself or a child, check them before you or your child touches
them.
NOTE
Your Mazda is equipp ed with ISOFIX/LATCH*1 lower anchors for attachment of specially
designed ISOFIX/LATCH
*1 child-restraint systems on the rear seats. When using these
anchors to secure a child-rest raint system, refer to "Using IS OFIX Lower Anchor (Mexico)/
Using LATCH Lower Anchor (Except Mexico)" (page 2-47).

Installing Child-RestraintSystems
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 systems it is clearly unsafe
due to air bags.

NOTE
Even if your vehicle is equipped with front
passenger occupant classification sensor
(page 2-66), 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-restrain t systems now come
with tethers and therefore 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
2-47).

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.

WARNING
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.
Tether strapForward
Tether strap
Forward
Always install the head restraint and adjust
it to the appropriate position after
removing the child-restraint system:
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 system
to the rear LATCH
lower anchors. Refer to “Using LATCH
Lower Anchor” (page 2-47).
NOTE
Follow the child-restraint system
manufacturer's instru ctions carefully. If
you are not sure whether you have a
LATCH system or tether, check in the
child-restraint system 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.
