2021 MAZDA MODEL 3 HATCHBACK Owners Manual

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.
*1ISOFIX (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.

NOTE
The ISOFIX/LATCH*1 lower
anchors marking on the cover
indicates the position of the
ISOFIX/LATCH
*1 lower anchors
for the attachment of a
child-restraint system.
Store the removed cover so that it
does not get lost.
4. 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.
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-restraint 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)
WARNING
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.

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
di fferent 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 Classi fication 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 in flating air bag.
Reduce the possibility of injuries
during an accident that is not
designed for air bag in flation, 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.

SRS Air Bags
*Some models.2-55
Mazda3_8JM2-EA -20H_Edition1_new 2020-7-10 17:21:34

If your vehicle is also equipped with a
front passenger occupant
classification system, refer to the Front
Passenger Occupant Classi fication
System (page 2-70) for details.
If your vehicle is equipped with a front
passenger occupant classi fication
system, the front passenger air bag
deactivation indicator light illuminates
for a speci fied 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 in flate 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 in flate 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 in flation 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 place any objects on the
assist grips. Only hang clothes
directly on the coat hooks.
Do not touch the components of the
supplemental restraint system after
the air bags have in flated:
Touching the components of the
supplemental restraint system after the
air bags have infl ated is dangerous.
Immediately after inflation, they are
very hot. You could get burned.
Never install any front-end equipment
to your vehicle:
Installation of front-end equipment,
such as frontal protection bar
(kangaroo bar, bull bar, push bar, or
other similar devices), snowplow, or
winches, is dangerous. The air bag
crash sensor system could be a ffected.
This could cause air bags to inflate
unexpectedly, or it could prevent the
air bags from inflating during an
accident. Front occupants could be
seriously injured.
Do not modify the suspension:
Modifying the vehi cle suspension is
dangerous. If the vehicle's height or
the suspension is modi fied, the vehicle
will be unable to accurately detect a
collision or roll-over accident resulting
in incorrect or unexpected air bag
deployment and the possibility of
serious injuries.To prevent false detection by the air
bag sensor system, heed the
following:
 Do not use tires or wheels other than
those speci fied for your Mazda:
Use of any tire or wheel other than
those specified for your Mazda (page
9-10) is dangerous. Use of such
wheels will prevent the vehicle's
accident detections system from
accurately detecting a collision or
roll-over accident resulting in
incorrect or unexpected air bag
deployment and the possibility of
serious injuries.
 Do not overload your vehicle:
Overloading your vehicle is
dangerous as it could prevent the air
bag crash sensor system from
accurately detecting a collision or
roll-over accident resulting in
incorrect or unexpected air bag
deployment and the possibility of
serious injuries. The gross axle
weight rating (GAWR) and the gross
vehicle weight rating (GVWR) for
your vehicle are on the Motor
Vehicle Safety Standard Label on the
driver's door frame. Do not exceed
these ratings.
 Do not drive the vehicle o ff-road:
Driving your Mazda off-road is
dangerous because the vehicle has
not been designed to do so. Driving
the vehicle o ff-road could prevent
the air bag crash sensor system from
accurately detecting a collision or
roll-over accident resulting in
incorrect or unexpected air bag
deployment and the possibility of
serious injuries.
