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 2-71). 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 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.
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*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-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
*1 lower anchors.
Always follow the child-restraint
system manufacturer's instructions.

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.

2. Anchor bracket

(5–Door)
1. Tether strap
2. Anchor bracket
3. Forward

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 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.

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
child-restraint system installation at
other seating positions. Child-restraint
systems 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 child-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
systems to the same ISOFIX/LATCH
*1
lower anchor. If your child-restraint
system has a tether, it must also be
used for your child's optimum safety.

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

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 indicators.
These indicators are visible in the area
where the air bags are installed.
The air bags are installed 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 ba g 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 parts
of the body.
Hold the driver in a position which
allows better control of the vehicle.

Mazda3_8JM2-EA-20H_Edition2_new 2020-8-19 13:13:07

If your vehicle is also equipped with a
front passenger occupant
classification system, refer to the Front
Passenger Occupant Classification
System (page 2-70) 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 which child-restraint
system is necessary for your child and
follow the installation directions in this
Owner's Manual as well as the
child-restraint system manufacturer's
instructions.
WARNING
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.

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.
Do not sit too close to the driver and
front passenger air bags:
Sitting too close to the driver and front
passenger air bag modules or placing
hands or feet on them is extremely
dangerous. The driver and front
passenger air bags inflate with great
force and speed. Serious injuries could
occur if someone is too close. The
driver should always hold onto only the
rim of the steering wheel. The front
seat passenger should keep both feet
on the floor. Front seat occupants
should adjust their seats as far back as
possible and always sit upright against
the seatbacks with seat belts worn
properly.
Sit in the center of the seat and wear
seat belts properly:
Sitting too close to the side air bag
modules or placing hands on them, or
sleeping up against the door or
hanging out the windows is extremely
dangerous. The side and curtain air
bags inflate with great force and speed
directly expanding along the door on
the side the car is hit. Serious injury
could occur if someone is sitting too
close to the door or leaning against a
window, or if rear seat occupants grab
the sides of the front seatbacks. Give
the side and curtain air bags room to
work by sitting in the center of the seat
while the vehicle is moving with seat
belts worn properly.
Do not attach objects on or around
the area where air bags deploy:
Attaching objects to the air bags or
placing something in the area where
the air bags deploy is dangerous. In an
accident, an object could interfere with
air bag inflation and injure the
occupants. Furthermore, the bag could
be damaged causing gases to release.
Always keep the deployment area of
the air bag modules free of any
obstructions.
For example, you should not do any of
the following as it may interfere with
air bag deployment.
Do not put a covering on or lean
anything against areas such as the
dashboard and lower portion of the
instrument panel that blocks the
passenger front air bag and knee air
bags.
 Do not use seat covers on the front
seats and rear seats equipped with
in-seat side air bags.
 Do not hang any backpacks, bags or
pouches that cover the sides of the
seats that block the side air bags.

Do not modify a front door or leave
any damage unrepaired. Always have
an Authorized Mazda Dealer inspect a
damaged front door:
Modifying a front door or leaving any
damage unrepaired is dangerous. Each
front door has a side crash sensor as a
component of the supplemental
restraint system. If holes are drilled in a
front door, a door speaker is left
removed, or a damaged door is left
unrepaired, the sensor could be
adversely affected causing it to not
detect the pressure of an impact
correctly during a side collision. If a
sensor does not detect a side impact
correctly, the side and curtain air bags
and the front seat belt pretensioner
may not operate norm ally which could
result in serious injury to occupants.
Do not modify the supplemental
restraint system:
Modifying the components or wiring of
the supplemental restraint system is
dangerous. You could accidentally
activate it or make it inoperable. Do
not make any modifications to the
supplemental restraint system. This
includes installing trim, badges, or
anything else over the air bag modules.
It also includes installing extra
electrical equipment on or near system
components or wiring. An Authorized
Mazda Dealer can provide the special
care needed in the removal and
installation of front seats. It is
important to protect the air bag wiring
and connections to assure that the
bags do not accidentally deploy, and
that the front passenger occupant
classification system and the seats
retain an undamaged air bag
connection.Do not place luggage or other objects
under the front seats:
Placing luggage or other objects under
the front seats is dangerous. The
components essential to the
supplemental restraint system could be
damaged, and in the event of a side
collision, the appropriate air bags may
not deploy, which could result in death
or serious injury. To prevent damage to
the components essential to the
supplemental restraint system, do not
place luggage or other objects under
the front seats.
Do not operate a vehicle with
damaged air bag/seat belt
pretensioner system components:
Expended or damaged air bag/seat
belt pretensioner system components
must be replaced after any collision
which caused them to deploy or
damage them. Only a trained
Authorized Mazda Dealer can fully
evaluate these systems to see that they
will work in any subsequent accident.
Driving with an expended or damaged
air bag or pretensioner unit will not
afford you the necessary protection in
the event of any subsequent accident
which could result in serious injury or
death.
Do not remove interior air bag parts:
Removing any components such as the
front seats, front dashboard, the
steering wheel or pa rts on the front
and rear window pillars and along the
roof edge, containing air bag parts or
sensors is dangerous. These parts
contain essential air bag components.
The air bag could accidentally activate
and cause serious injuries. Always have
an Authorized Mazda Dealer remove
these parts.
