MAZDA MODEL 3 SEDAN 2019 Repair Manual

▼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.

Do not allow a child or anyone to lean over
or against the side window of a vehicle
with side and curtain air bags:
It is dangerous to allow anyone to lean
over 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 or against the front door could block
the side and curtain air bags and eliminate
the advantages of supplemental
protection. With the front air bag and the
additional side air bag that comes out of
the front seat, the rear seat is always a
better location for children. Take special
care not to allow a child to lean over or
against the side window, even if the child is
seated in a child-restraint system.
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.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.
Front Passenger's Seat Child-Restraint
System Installation (With Front
Passenger Occupant Classification
System)
1. Make sure the ignition is switched off.
2. Slide the seat as fa r 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 syst em 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 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.
▼ Using ISOFIX Lower Anchor
(Mexico)/Using LATCH Lower
Anchor (Except Mexico)
Your Mazda is equipped with ISOFIX/
LATCH
*1 lower anchors for attachment of
specially designed ISOFIX/LATCH
*1
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
*1
child-restraint system s must also be used
in conjunction with a te ther 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 according to the
child-restraint system manufacturer's
instructions.

Never attach two child-restraint systems to
the same ISOFIX/LATCH
*1 lower anchor:
Attaching two child-restraint systems to
the same ISOFIX/LATCH
*1 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
*1 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
*1 lower anchors for ISOFIX/
LATCH
*1 child-restraint systems.
Make sure there are no seat belts or foreign
objects near or around the ISOFIX/LATCH
*1
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
*1 lower anchors and the
child-restraint system is installed
improperly, the child-re straint 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
*1 lower anchors.
Always follow the child-restraint system
manufacturer's instructions.
*1 ISOFIX (Mexico)/LATCH (Except Mexico)
Installation on rear outboard seats
1. First, adjust the front seat to allow clearance between the child-restraint
system and the front seat.
Refer to Adjusting the Driver's Seat on
page 2-5.
Refer to Adjusting the Front
Passenger's Seat on page 2-13.
2. Make sure the seatback is securely
latched by pushing it back until it is
fully locked.

5. Secure the child-restraint system using
BOTH ISOFIX/LATCH
*1 lower
anchors, following the child-restraint
system manufacturer's instruction. Pull
on the child-restrain t 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.
*1 ISOFIX (Mexico)/LATCH (ExceptMexico)
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.

Installation on rear center seat
The ISOFIX/LATCH*1 lower anchors at
the center of the rear seat are much further
apart than the sets of ISOFIX/LATCH
*1
lower anchors for ch ild-restraint system
installation at other seating positions.
Child-restraint syste ms with rigid ISOFIX/
LATCH
*1 attachments cannot be installed
on the center seating position. Some
ISOFIX/LATCH
*1 equipped
child-restraint systems can be placed in the
center position and will reach the nearest
ISOFIX/LATCH
*1 lower anchors which
are 434 mm (17.1 in) apart. ISOFIX/
LATCH
*1 compatible child-restraint
systems (with attachments on belt
webbing) can be used at this seating
position only if the c hild-restraint system
manufacturer's instructions state that the
child-restraint system can be installed to
ISOFIX/LATCH
*1 lower anchors that are
434 mm (17.1 in) apart. Do not attach two
child-restraint sy stems to the same

Supplemental Restraint
System (SRS) Precautions
▼ Supplemental Restraint System
(SRS) Precautions
The front and side supplemental restraint
systems (SRS) include
different types of
air bags. Please verify the different types
of air bags which are equipped on your
vehicle by locating the “SRS AIRBAG”
location in dicators. These indicators are
visible in the area where the air bags are
installed.
The air bags are insta lled in the following
locations:

The steering wheel hub (driver air bag)
The front passenger dashboard (front
passenger air bag)
Under the instrument panel (driver and
front passenger
* knee air bags)
The outboard sides of the front
seatbacks (side air bags)
The front and rear window pillars, and
the roof edge along both sides (curtain
air bags)

Vehicles with the Front Passenger
Occupant Classification System have a
sensor which detects an impending
roll-over accident.

The air bag supplemental restraint systems
are designed to provide supplemental
protection in certain situations so seat belts
are always important in the following
ways:

Without seat belt usage, the air bags
cannot provide adequate protection during
an accident. Seat belt usage is necessary
to:
Keep the occupant from being thrown
into an inflating air bag.
Reduce the possibility of injuries during
an accident that is not designed for air
bag inflation, such as rear impact.
Reduce the possibility of injuries in
frontal, near frontal or side collisions or
roll-over accidents that are not severe
enough to activate the air bags.
Reduce the possibility of being thrown
from your vehicle.
Reduce the possibility of injuries to
lower body and legs during an accident
because the air bags provide no
protection to these p arts of the body.
Hold the driver in a position which
allows better control of the vehicle.

If your vehicle is also equipped with a
front passenger occupant classification
system, refer to the Front Passenger
Occupant Classification System (page
2-71) for details.
If your vehicle is equipped with a front
passenger occupant classification 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 children must
use a child-restraint system (page 2-32).

Carefully consider wh ich child-restraint
system is necessary for your child and
follow the installation directions in this
Owner's Manual as well as the
child-restraint syst em 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 appropriate air
bags can be expected to inflate only in the
first accident, such as frontal, near frontal
or side collisions or roll-over accidents that
are at least moderate. Vehicle occupants
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 bag 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-restraint system for
the child's age and size.
