2020 MAZDA MODEL 3 HATCHBACK Owners Manual (in English)

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 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 accident, an object could interfere with
air bag inflation and injure the occupants.
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 seats, 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
curtain air bag activates such as on the
windshield glass, side door glass, front and
rear window pillars 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
redirecting 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 the 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 vehi cle's height or the
suspension is modified, 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
specified for your Mazda:
Use of any tire or wheel other than those specified for your Mazda (page 9-9) 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 off-road:
Driving your Mazda off-road is
dangerous because the vehicle has not
been designed to do so. Driving the
vehicle off-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.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 normally
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 parts on the front and rear
window pillars and al ong 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 Deal er 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.

How the SRS Air BagsWo r k
▼How the SRS Air Bags Work
Your Mazda is equipped with the
following types of SRS air bags. SRS air
bags are designed to work together with
the seat belts to help to reduce injuries
during an accident.
The SRS air bags are designed to provide
further protection for passengers in
addition to the seat belt functions. Be sure
to wear seat belts properly.
▼Front Seat Bel
t Pretensioners
The front seat belt pretensioners are
designed to deploy in moderate or severe
frontal, near frontal collisions.
In addition, the pretensioners operate
when a side collision or a roll-over
accident is detected. The pretensioners
operate differently depending on what
types of air bags are equipped. For more
details about seat belt pretensioner
operation, refer to the SRS Air Bag
Deployment Criteria (page 2-68).
▼Driver Air Bag
The driver's air bag is mounted in the
steering wheel.
When air bag crash sensors detect a frontal
impact of greater than moderate force, the
driver's air bag inflates quickly helping to
reduce injury mainly to the driver's head
or chest caused by directly hitting the
steering wheel.
For more details about air bag
deployment, refer
to "SRS Air Bag
Deployment Criteria" (page 2-68).
(With Front Passenger Occupant
Classification System)
The driver's dual-stag e air bag controls air
bag inflation in two energy stages. During
an impact of moderate severity, the
driver's air bag deploys with lesser energy,
whereas during more severe impacts, it
deploys with more energy.
