2023 MAZDA CX3 child seat

If your vehicle is also equipped with a
front passenger occupant
classification system, refer to the Front
Passenger Occupant Classification
System (page 2-66) 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 2-30).

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 remove interior air bag parts:
Removing any components such as the
front seats, front dashboard, the
steering wheel or parts 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.
Properly dispose of the air bag
system:
Improper disposal of an air bag or a
vehicle with live air bags in it can be
extremely dangerous. Unless all safety
procedures are followed, injury could
result. Have an Authorized Mazda
Dealer safely dispose of the air bag
system or scrap an air bag equipped
vehicle.
NOTE
If it becomes necessary to have the
components or wiring system for the
supplementary restraint system
modified to accommodate a person
with certain medical conditions in
accordance with a certified
physician, contact an Authorized
Mazda Dealer, refer to “Customer
Assistance (U.S.A.)” (page 8-2).
When an air bag deploys, a loud
inflation noise can be heard and
some smoke will be released.
Neither is likely to cause injury,
however, the texture of the air bags
may cause light skin injuries on body
parts not covered with clothing
through friction.
Should you sell your Mazda, we urge
you to tell the new owner of its air
bag systems and that familiarization
with all instructions about them,
from the Owner's Manual, is
important.
This highly-visible label is displayed
which warns against the use of a
rear-facing child-restraint system on
the front passenger seat.

deactivation indicator light on/off condition
chart indicates.

If the front passenger air bag
deactivation indicator light does not
illuminate when the ignition is
switched ON and does not illuminate
as indicated in the front passenger air
bag deactivation indicator light on/off
condition chart, do not allow a child to
sit in the front passenger seat and
consult an Authorized Mazda Dealer
as soon as possible. The system may
not work properly in an accident.
WARNING
Do not decrease the total seated
weight on the front passenger seat:
When an adult or large child sits on the
front passenger seat, decreasing the
total seated weight on the front
passenger seat required for air bag
deployment is dangerous. The front
passenger seat weight sensors will
detect the reduced total seated weight
condition and the front passenger front
and side air bags and knee air bags,
and the seat belt pretensioner system
will not deploy during an accident. The
front passenger will not have the
supplementary protection of the air
bag, which could result in serious
injury. Decreasing the total seated
weight on the front passenger seat
could result in an air bag not deploying
under the following conditions, for
example:

Do not increase the total seated
weight on the front passenger seat:
When an infant or small child sits on
the front passenger seat, increasing the
total seated weight on the front
passenger seat is dangerous. The front
passenger seat we ight sensors will
detect the increased total seated
weight, which could result in the
unexpected deployment of the front
passenger front and side air bags and
knee air bags, and seat belt
pretensioner system in an accident and
may cause serious injury. Increasing the
total seated weight on the front
passenger seat could result in the front
passenger front and side air bags and
knee air bags, and seat belt
pretensioner system deployment in an
accident under the following
conditions, for example:
 Luggage or other items are placed on
the seat with the child in the
child-restraint system.
