Mazda 3 (2024 year). Manual in english

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 systems
it is clearly unsafe due to air bags.

NOTE

Even if your vehicle is equipped with
front passenger occupant classiﬁcation
sensor (page 3-18), 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 therefore must
be installed on the seats that take
tethers to be eﬀective.

Some child-restraint systems also
employ specially designed ISOFIX/
LATCH

attachments; refer to " How

to Use the ISOFIX Lower Anchor
(Mexico)/LATCH Lower Anchor
(Except Mexico)"(page 3-67).

Anchor Bracket Overview

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, if the
seat is equipped with a head restraint,
remove it. Always follow the
instruction manual accompanying the
child-restraint system.

Warnings and Cautions

for Using the Anchor

Bracket

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.

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.

(Mexico)

If the top tether strap does not reach
the anchor bracket, purchase and use
an extension strap provided by the CRS
manufacturer.

How to Use the

Automatic Locking Mode

(Except Mexico)

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 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. First, adjust the front seat to allow

clearance between the
child-restraint system and the front
seat.
Refer to How to Use the Front Seats
on page 3-34.

2. Make sure the seatback is securely

latched by pushing it back until it is
fully locked.

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.
Refer to How to Use the Head
Restraints on page 3-44.

4. 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.

5. To get the retractor into the

automatic 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 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.

7. If your child-restraint system

requires the use of a tether strap,
refer to the manufacturer's

Equipment to Protect Occupants/Pedestrians

instructions to hook and tighten the
tether strap.

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
an occupant classiﬁcation 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 ISOFIX/LATCH

child-restraint system cannot be
secured in the front passenger's seat
and should be used in the second-row
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.

1 ISOFIX (Mexico)/LATCH (Except

Mexico)

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:

pillars along the roof edge.

Warnings and Cautions
for Using the Front Seat

for Children

WARNING

Always move the front passenger seat
as far back as possible if installing a
front-facing child-restraint system on
it is unavoidable.

As your vehicle has front air bags and
doubly so because your vehicle has
side air bags, a front-facing
child-restraint system should be put on
the front passenger seat only when it is
unavoidable.
Even if the front passenger air bag
deactivation indicator light illuminates,
always move the seat as far back as
possible, because the force of a
deploying air bag could cause serious
injury or death to the child.

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 in a moderate collision, the
child-restraint system can be hit by a
deploying air bag and moved violently
backward resulting in serious injury or
death to the child. Even though you
may feel assured that the front
passenger air bag will not deploy
based on the fact that the front
passenger air bag deactivation
indicator light illuminates, you should
not use a rear-facing child-restraint
system in the front seat.

2023-4-17 20:22:43

Always remove the head restraint and
install child-restraint system (except
when installing a backless booster
seat).

Always install the head restraint and
adjust it to the appropriate position
after removing the child-restraint
system.

Do not allow a child or anyone to
lean over to or against the side
window of a vehicle with side and
curtain air bags.

It is dangerous to allow anyone to lean
over to or against the side window, the
area of the front passenger seat, the
front and rear window pillars and the
roof edge along both sides from which
the side and curtain air bags deploy,
even if a child-restraint system is used.
The impact of inﬂation from a side or
curtain air bag could cause serious
injury or death to an out of position
child. Furthermore, leaning over to or
against the door could block the side
and curtain air bags and eliminate the
advantages of supplemental
protection. Because the front seats are
equipped with front air bags, the rear
seat is always a better location for
children. Take special care not to allow
a child to lean over to or against the
side window, even if the child is seated
in a child-restraint system.

How to Install a

Child-Restraint System

on the Front Passenger's

Seat (With Front

Passenger Occupant

Classiﬁcation System)

1. Make sure the vehicle power is

switched oﬀ.

2. Slide the seat as far back as

possible.

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-restraint system on

the seat without putting your
weight on the seat and fasten the
seat belt. See the manufacturer's
instructions on the child-restraint
system for belt routing instructions.

5. To get the retractor into the

automatic 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 clicking noise from the
retractor will be heard during
retraction if the system is in
automatic locking mode. If the belt
does not lock the seat down tight,
repeat the previous step and also
this one.

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.



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 from the child-restraint
system manufacturer.

8. Switch the vehicle power ON and

make sure the front passenger air
bag deactivation indicator light
illuminates after installing a
child-restraint system on the front
passenger seat.
If the front passenger air bag
deactivation indicator light does
not illuminate, remove the
child-restraint system, switch the
vehicle power to OFF, and then
re-install the child-restraint system
(page 3-18).

WARNING

Do not seat a child in a child-restraint
system on the front passenger seat if
the front passenger air bag
deactivation indicator light does not
illuminate.

While it is always better to install any
child-restraint system on the rear seat,
it is imperative that a child-restraint
system

ONLY

be used on the front

passenger seat if the deactivation
indicator light illuminates when the
child is seated in the child-restraint
system (page 3-18). Seating a child in
a child-restraint system installed on the
front passenger seat with the front
passenger air bag deactivation
indicator light not illuminated is
dangerous. If this indicator light does
not illuminate, this means that the
front passenger front and side air bags,
and knee air bags, and seat belt
pretensioners are ready for
deployment. If an accident were to
deploy an air bag, a child in a
child-restraint system sitting in the
front passenger seat could be seriously
injured or killed. If the indicator light
does not illuminate after seating a
child in a child-restraint system on the
front passenger seat, seat a child in a
child-restraint system on the rear seat
and consult an Authorized Mazda
Dealer as soon as possible.

Using the ISOFIX Lower

Anchor (Mexico)/LATCH

Lower Anchor (Except

Mexico)

Your Mazda is equipped with ISOFIX/
LATCH

lower anchors for attachment

of specially designed ISOFIX/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 ISOFIX/
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.

Mexico)

Warnings and Cautions

for Using the ISOFIX

Lower Anchor (Mexico)/

LATCH Lower Anchor

(Except Mexico)

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 ISOFIX/LATCH

lower anchor.

Attaching two child-restraint systems
to the same ISOFIX/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 ISOFIX/
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
attach it to BOTH ISOFIX/LATCH

lower anchors for ISOFIX/LATCH

child-restraint systems.

Make sure there are no seat belts or
foreign objects near or around the
ISOFIX/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 ISOFIX/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
ISOFIX/LATCH

lower anchors.

Always follow the child-restraint
system manufacturer's instructions.

manufacturer's instructions when
installing tethers.

1 ISOFIX (Mexico)/LATCH (Except

Mexico)

Installation on rear center seat

The ISOFIX/LATCH

lower anchors at

the center of the second-row seat are
much further apart than the sets of
ISOFIX/LATCH

lower anchors for

child-restraint system installation at
other seating positions. Child-restraint
systems with rigid ISOFIX/LATCH

attachments cannot be installed on the
center seating position. Some ISOFIX/
LATCH

equipped child-restraint

systems can be placed in the center
position and will reach the nearest
ISOFIX/LATCH

lower anchors which

are 434 mm (17.1 in) apart. ISOFIX/
LATCH

compatible child-restraint

systems (with attachments on belt
webbing) can be used at this seating
position only if the child-restraint

system manufacturer's instructions
state that the child-restraint system can
be installed to ISOFIX/LATCH

lower

anchors that are 434 mm (17.1 in)
apart. Do not attach two child-restraint
systems to the same ISOFIX/LATCH

lower anchor. If your child-restraint
system has a tether, it must also be
used for your child's optimum safety.

The procedure for installation on the
rear outboard seats is the same.

Warnings and Cautions

When Using the Doors

WARNING

Opening/closing of the doors must be
done by an adult.

If a person's hand, foot, or neck is
pinched in a door, it could result in
serious injury.

Do not drive the vehicle with the
door-ajar warning light/indication
turned on/displayed.

Otherwise, the door may open
unexpectedly and result in an accident.

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, fuel-ﬁller
lid, and liftgate/trunk lid 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/trunk lid, always verify that
they are securely closed.

Doors and the liftgate/trunk lid not
securely closed are dangerous, if the
vehicle is driven with a door and the
liftgate/trunk lid not securely closed,
the door and the liftgate/trunk lid
could open unexpectedly resulting in
an accident.

Always conﬁrm the safety around the
vehicle before opening a door and the
liftgate/trunk lid.

Suddenly opening a door and the
liftgate/trunk lid is dangerous. A
passing vehicle or a pedestrian could
be hit and cause an accident.

CAUTION

Always conﬁrm the conditions around
the vehicle during strong winds or
when parked on an incline before
opening/closing the doors. Neglecting
to check the conditions around the
vehicle could result in ﬁngers getting
caught in the door or a passing
pedestrian being hit, resulting in an
unexpected accident or injury.

Inside Trunk Release

Lever (4-door)

Your vehicle is equipped with an inside
trunk release lever that provides a
means of escape for children and
adults in the event they become locked
inside the trunk.

No matter how careful adults might be
with keys and locking their cars,
parents should be aware that children
may be tempted to play around
vehicles and use the trunk as a hiding
place.

Adults are advised to familiarize
themselves with the operation and
location of the inside trunk release
lever so that all children can be told
about it in an appropriate way, keeping
in mind that most vehicles do not have
such levers.

Warnings and Cautions

for Using the Inside Trunk

Release Lever

WARNING

Close the trunk lid, be sure the seat
backs are latched and do not allow
children to play inside the vehicle.

Leaving the trunk lid open or leaving
children in the vehicle with the keys is
dangerous. Children could open the
trunk lid and climb inside resulting in
possible injury or death from heat
exposure.

Always keep the car from being a
tempting place to play by latching the
rear seats, doors and the trunk, and
keeping the keys where children can
not play with them.

Leaving children or animals unattended
in a parked vehicle is dangerous.
Babies left sleeping and children who
lock themselves in cars or trunks can
die very quickly from heat prostration.
Do not leave your children or pets
alone in a car at any time. Do not leave
the car, the rear folding seats or the
trunk unlocked.
