2020 MAZDA MODEL 3 HATCHBACK Owners Manual (in English)

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.

(Mexico)
NEVER use a rearward facing child restraint
on a seat protected by an ACTIVE AIRBAG in
front of it, DEATH or SERIOUS INJURY to the
CHILD can occur.
Vehicles with a front passenger air bag
have the following warning label. The
warning label reminds you not to put a
rear-facing child-restraint system on the
front passenger seat at any time.

(Except Mexico)
Vehicles with a front passenger air bag
have the following warning label. The
warning label reminds you not to put a
rear-facing child-restraint system on the
front passenger seat at any time.
Do not install a front-facing child-restraint
system on the front passenger seat unless it
is unavoidable:
In a collision, the force of a deploying air
bag could cause serious injury or death to
the child. If installing a front-facing
child-restraint system on the front
passenger seat is unavoidable, move the
front passenger seat as far back as
possible.
Seating a child in a child-restraint system
on the front passenger seat is dangerous
under certain conditions (With Front
Passenger Occupant Classification System):
Your vehicle is equipped with front
passenger seat weight sensors. Even with
the front passenger seat weight sensors, if
you must use the front passenger seat to
seat a child, using a child-restraint system
on the front passenger seat under the
following conditions increases the danger
of the front passenger air bag deploying
and could result in serious injury or death
to the child.
The front passenger air bag deactivation
indicator light does not illuminate when
seating a child in the child-restraint
system.

Luggage or other items are placed on the
seat with the child in the child-restraint
system.
 A rear passenger or luggage pushing or
pulling down on the front passenger
seatback.
 Luggage or other items are placed on the
seatback or hung on the head restraint.
 The seat is washed.
 Liquids are spilled on the seat.
 The front passenger seat is moved
backward, pushing into luggage or other
items placed behind it.
 The front passenger seatback contacts
the rear seat.
 Luggage or other items are placed
between the front passenger seat and
driver seat.
 An electric device is put on the front
passenger's seat.
 An additional electrical device, such as a
seat warmer is installed to the surface of
the front passenger seat.
 Any accessories, which might increase
the total seated weight on the front
passenger seat, are attached to the front
passenger seat.
The designated positions with seat belts on
the rear seats are the safest places for
children. Always use seat belts and child
restraints.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.
Never use one seat belt on more than one
person at a time:
Using one seat belt for more than one
person at a time is dangerous. A seat belt
used in this way cannot spread the impact
forces properly and the two passengers
could be crushed together and seriously
injured or even killed. Never use one belt for
more than one person at a time and always
operate the vehicle with each occupant
properly restrained.
