ECU MAZDA MODEL 3 HATCHBACK 2020 (in English) User Guide

WA R N I N G
Use the correct size child-restraint system:
For effective protection in vehicle accidents
and sudden stops, 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 according 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
vehicle 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 indicator light illuminates.
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.

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.

3. 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 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 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.
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.

▼If You Must Use th
e 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 shou lder belt over the
shoulder.
NEVER put a rear-fac ing 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
*1
child-restraint system cannot be secured in
the front passenger's seat and should be
used in the rear 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:
Mazda vehicles equipped with curtain
air bag will have an "SRS AIRBAG"
marking on the window pillars along the
roof edge.
WA R N I N G
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.

6. 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 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-rest raint 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 sy stem, it may not
employ seat belts which are in
automatic locking mode.
7. Seat your child safely in the
child-restraint sy stem and secure the
child according to the instructions
from the child-restraint system
manufacturer.
8. Switch the ignition 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 i gnition to OFF, and
then re-install th e child-restraint
system (page 2-72).

WA R N I N G
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 2-72). 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.
