2019 MAZDA MODEL 3 HATCHBACK Owners Manual (in English)

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.

▼Front Passenger Air Bag
The front passenger air bag is mounted in
the front passenger dashboard.
The inflation mechanism for the front
passenger air bag is the same as the
driver's air bag.
For more details about air bag
deployment, refer to "SRS Air Bag
Deployment Crite
ria" (page 2-68).
(With Front Passenger Occupant
Classification System)
In addition, the front passenger air bag is
designed to only deploy in accordance
with the total seated weight on the front
passenger seat. For details, refer to the
front passenger occupant classification
system (page 2-71).
▼ Driver and Front Passenger Knee
Air Bags*
The knee air bags are equipped under the
instrument panel.
If the air bag crash
sensors receive a
frontal impact of greater than moderate
force, the knee air bags deploy
immediately to reduce impact to the driver
and front passenger's legs.
For more details about air bag
deployment, refer to "SRS Air Bag
Deployment Criteria" (page 2-68).
▼ Side Air Bags
The side air bags are mounted in the
outboard sides of the front seatbacks.
When the air bag crash sensors detect a
side impact of greater than moderate force,
the system inflates the side air bag only on
the side in which the vehicle was hit. The
side air bag inflates quickly to reduce
injury to the driver or front passenger's
chest caused by directly hitting interior
parts such as a door or window.
For more details about air bag
deployment, refer to "SRS Air Bag
Deployment Criteria" (page 2-68).

(With Front Passenger Occupant
Classification System)
In addition, the front passenger side air
bag is designed to only deploy in
accordance with the total seated weight on
the front passenger seat. For details, refer
to the front passenger occupant
classification system (page 2-71).

▼ Curtain Air Bags
The curtain air bags are mounted in the
front and rear window pillars, and the roof
edge along both sides.
When the air bag cra
sh sensors detect a
side impact of greater than moderate force,
the curtain air bag inflates quickly and
helps to reduce injury mainly to the driver
and front and rear outboard passengers'
heads caused by direct ly hitting interior
parts such as a door or window.
For more details about air bag
deployment, refer to "SRS Air Bag
Deployment Criteria" (page 2-68).
In a side impact:
Greater than moderate impact to one side
of the vehicle will cau se the curtain air bag
on that side only to inflate.

Only one side curtain air bag will deploy
on the side of the veh icle that receives the
force of an impact.
(With Front Passenger Occupant
Classification System)
In a roll-over:
In response to a vehicle roll-over, both
curtain air bags inflate.

Both curtain air bags will deploy after the
roll-over accident is detected.
