2019 MAZDA MODEL 3 HATCHBACK wiring

Have your seat belts changed immediately
if the pretensioner or load limiter has been
expended:
Always have an Authorized Mazda Dealer
immediately inspect the seat belt
pretensioners and air bags after any
collision. Like the air bags, the seat belt
pretensioners and load limiters will only
function once and must be replaced after
any collision that caused them to deploy. A
seat belt with an expended pretensioner or
load limiter is still better than wearing no
seat belt at all; however, if the seat belt
pretensioners and load limiters are not
replaced, the risk of injury in a collision will
increase.
Do not modify the components or wiring,
or use electronic testing devices on the
pretensioner system:
Modifying the components or wiring of the
pretensioner system, including the use of
electronic testing devices is dangerous. You
could accidentally activate it or make it
inoperable which would prevent it from
activating in an accident. The occupants or
repairers could be seriously injured.
Properly dispose of the pretensioner
system:
Improper disposal of the pretensioner
system or a vehicle with non-deactivated
pretensioners is dangerous. Unless all
safety procedures are followed, injury could
result. Have an Authorized Mazda Dealer
safely dispose of the pretensioner system or
scrap a pretensioner system equipped
vehicle.NOTE
The pretensioner system may not
operate depending on the type of the
collision. For details, refer to the SRS
Air Bag Deployment Criteria (page
2-68).
Some smoke (non-toxic gas) will be
released when the air bags and
pretensioners deploy. This does not
indicate a fire. This gas normally has no
effect on occupants, however, those with
sensitive skin may experience light skin
irritation. If residue from the
deployment of the air bags or the
pretensioner system gets on the skin or
in the eyes, wash it off as soon as
possible.

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.

If the front passenger air bag
deactivation indicator light illuminates
when an adult is seated in the front
passenger seat, have the passenger
re-adjust their posture by sitting with
their feet on the floor, and then
re-fastening the seat belt. If the front
passenger air bag deactivation indicator
light still illuminates, move the
passenger to the rear seat. If sitting in
the rear seat is not possible, slide the
front passenger seat as far back as
possible. Consult an Authorized Mazda
Dealer as soon as possible.
▼Driver and Front Passenger Buckle
Switches
The buckle switches on the front seat belts
detect whether or not the front seat belts
are securely fastened and further control
the deployment of the air bags.

ts of the air bag
