MAZDA MODEL CX-3 2021 Repair Manual

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.
Tether strapForward
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 ch ild-restraint system
installation at other seating positions.
Child-restraint system s 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 360 mm (14.2 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
360 mm (14.2 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 for installation on the rear
outboard seats is the same.

Supplemental Restraint System (SRS) Precautions
The front and side supplemental restraint system s (SRS) include different types of air bags.
Please verify the different types of air b ags 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)
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 th rown 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 parts of the body.

CX-3_8JL1-EA-20G_Edition1_old 2020-5-22 15:31:00

Hold the driver in a position which allows better control of the vehicle.

If your vehicle is also equipped with a fr ont passenger occupant classification system,
refer to the Front Passenger Occupant Cla ssification System (page 2-66) for details.
If your vehicle is equipped with a front pass enger 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-rest raint 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.
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 occu pants 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 ba g 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-restrain t 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 viol ently 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 someon e 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 extrem ely 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 side s of the front seatbacks. Give the side and
curtain air bags room to work by sitting in th e center of the seat while the vehicle is moving
with seat belts worn properly.
Do not attach objects on or around the area where driver and front passenger air bags
deploy:
Attaching an object to the driver and front passenger air bag modules or placing something
in front of them is dangerous. In an acci dent, an object could interfere with air bag
inflation
and injure the occupants.

CX-3_8JL1-EA-20G_Edition1_old 2020-5-22 15:31:00

Do not attach objects on or around the area where a side air bag deploys:
Attaching objects to the front seat in such a way as to cover the outboard side of the seat in
any way is dangerous. In an accident the object could interfere with the side air bag, which
inflates from the outboard side of the front seat s, impeding the added protection of the side
air bag system or redirecting the air bag in a way that is dangerous. Furthermore, the bag
could be cut open releasing the gas.
Do not hang net bags, map pouches or backpacks with side straps on the front seats. Never
use seat covers on the front seats. Always keep the side air bag modules in your front seats
free to deploy in the event of a side collision.
Do not attach objects on or around the area where a curtain air bag deploys:
Attaching objects to the areas where the curtai n air bag activates such as on the windshield
glass, side door glass, front and rear window pi llars and along the roof edge and assist grips is
dangerous. In an accident the object could interfere with the curtain air bag, which
inflates
from the front and rear window pillars and along the roof edge, impeding the added
protection of the curtain air bag system or redir ecting the air bag in a way that is dangerous.
Furthermore, the bag could be cut open releasing the gas.
Do not place hangers or any other objects on the assist grips. When hanging clothes, hang
them on the coat hook directly. Always keep th e curtain air bag modules free to deploy in the
event of a side collision or roll-over accident.
Do not touch the components of the supplemental restraint system after the air bags have
inflated:
Touching the components of the supplemental restraint system after the air bags have
inflated 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 affected. 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 vehicle suspension is dangerous. If the vehicle's height or the suspension is
modified, the vehicle will be unable to accura tely detect a collision or roll-over accident
resulting in incorrect or unexpected air bag depl oyment 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 th an those specified for your Mazda:
Essential Safety Equipment
SRS Air Bags
2-54
CX-3_8JL1-EA-20G_Edition1_old 2020-5-22 15:31:00

Use of any tire or wheel other than those specified for your Mazda (page 9-7) 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 rati ng (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 off-road:
Driving your Mazda off-road is dangerous beca use the vehicle has not been designed to do
so. Driving the vehicle off-road could prev ent the air bag crash sensor system from
accurately detecting a collision or roll-over acci dent resulting in incorrect or unexpected air
bag deployment and the possibility of serious injuries.
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 le ft 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 normally which could result in
serious injury to occupants.
Do not modify the supplemental restraint system:
Modifying the components or wiri ng 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 inst alling 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 th e 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 de ploy, 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 depl oy 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 damage d 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 se ats, 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 injuri es. 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 foll owed, injury could result. Have an Authorized
Mazda Dealer safely dispose of the air bag sy stem 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 text ure 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 wh ich warns against the use of a rear-facing
child-restraint system on the front passenger seat.
