2021 MAZDA MODEL CX-9 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
2-82).
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 front
pretensioner system gets on the skin or
in the eyes, wash it off 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 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 de tect 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 su pplemental 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 ac cidentally 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 th e 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 de ploy, which could result in death or serious
injury. To prevent damage to the components e ssential 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 pret ensioner system components must be replaced
after any collision which caused them to depl oy 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 se ats, front dashboard, the steering wheel or
parts 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 injuri es. 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 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

Constant Monitoring
The following components of the air bag systems are monitored by a diagnostic system:

Front air bag sensors
Crash sensors, and diagnostic module (SAS unit)
Side crash sensors
Air bag modules
Front seat belt pretensioners
Air bag/Front seat belt pretensioner system warning light
Related wiring
(With Front Passenger Occupant Classification System)
Front passenger occupant classification sensor
Front passenger occupant classification module
Front passenger air bag deactivation indicator light

The diagnostic module continuously monitors the system's readiness. This begins when the
ignition is switched ON and continue s while the vehicle is being driven.
