2021 MAZDA MODEL 3 SEDAN 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 2-67).
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 eff ect 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 o ff as soon as possible.

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 si de 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 norm ally 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 modi fications 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
classi fication 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
a ff ord 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 pa rts 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 systemmodi fied to accommodate a person
with certain medical conditions in
accordance with a certi fied
physician, contact an Authorized
Mazda Dealer, refer to “Customer
Assistance (U.S.A.)” (page 8-2).
When an air bag deploys, a loud in flation 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.

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.
