wiring MAZDA MODEL 3 4-DOOR 2018 Owners Manual

(With Front Passenger Occupant
Classification System)
In addition, the pretensioner system for the
front passenger, like the front and side
passenger air bag, is designed to only
deploy when the front passenger occupant
classification sensor detects a passenger
sitting on the front passenger's seat.
For details, refer to the front passenger
occupant classification sensor (page 2-
61).

Load limiter:
The load limiting system releases belt
webbing in a controlled manner to reduce
belt force on the occupant's chest. While
the most severe load on a seat belt occurs
in frontal collisions, the load limiter has an
automatic mechanical function and can
activate in any accident mode with
sufficient occupant movement.
Even if the pretensioners have not fired,
the load limiting function must be checked
by an Authorized Mazda Dealer.
WA R N I N G
Wear seat belts only as recommended in
this owner's manual:
Incorrect positioning of the driver and front
passenger seat belts is dangerous. Without
proper positioning, the pretensioner and
load limiting systems cannot provide
adequate protection in an accident and
this could result in serious injury. For more
details about wearing seat belts, refer to
"Fastening the seat belts" (page 2-15).
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.

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 9-10) is
dangerous. Use of such wheels will prevent th e 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 possibili ty 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 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 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 un repaired is dangerous. Each front door has a
side crash sensor as a component of the suppleme ntal 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 ma y 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 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.

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 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.
