belt MAZDA MODEL CX-9 2020 (in English) Service Manual

Never use a rear-facing child-restraint system in the front seat with an air bag that could
deploy:
Rear-facing child-restraint systems on the front seat are particularly dangerous even though
you may feel assured that a front passenger air bag will not deploy based on the fact that the
front passenger air bag deactivation indicator light illuminates. The child-restraint system
can be hit by a deploying air bag and moved viol ently backward resulting in serious injury or
death to the child.
Do not sit too close to the driver and front passenger air bags:
Sitting too close to the driver and front passenger air bag modules or placing hands or feet on
them is extremely dangerous. The driver and front passenger air bags inflate with great force
and speed. Serious injuries could occur if someon e is too close. The driver should always hold
onto only the rim of the steering wheel. The front seat passenger should keep both feet on the
floor. Front seat occupants should adjust their seats as far back as possible and always sit
upright against the seatbacks with seat belts worn properly.
Sit in the center of the seat and wear seat belts properly:
Sitting too close to the side air bag modules or placing hands on them, or sleeping up against
the door or hanging out the windows is extrem ely dangerous. The side and curtain air bags
inflate with great force and speed directly expanding
along the door on the side the car is hit.
Serious injury could occur if someone is sitting too close to the door or leaning against a
window, or if rear seat occupants grab the side s of the front seatbacks. Give the side and
curtain air bags room to work by sitting in th e center of the seat while the vehicle is moving
with seat belts worn properly.
Do not attach objects on or around the area where driver and front passenger air bags
deploy:
Attaching an object to the driver and front passenger air bag modules or placing something
in front of them is dangerous. In an acci dent, an object could interfere with air bag
inflation
and injure the occupants.

Use of any tire or wheel other than those specified for your Mazda (page 9-7) is
dangerous. Use of such wheels will prevent the 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 possibility of serious injuries. The gross axle weight
rating (GAWR) and the gross vehicle weight rati ng (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 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 le ft 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 wiri ng 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.
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 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 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 damage d 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 foll owed, 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.

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 Belt Pretensioners
The front seat belt pretensioner
s 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 pret ensioner operation, refer to the SRS Air Bag
Deployment Criteria (page 2-81).
▼ 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 2-81).
(With Front Passenger Occupant Classification System)
The driver's dual-stage air bag controls air bag inflation in two energy stages. During an
impact of moderate severity, the driver's ai r bag deploys with lesser energy, whereas during
more severe impacts, it de ploys 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.

Front Passenger Occupant Classification System*
First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-69) carefully.
▼Front Passenger Occupant
Classification Sensor
Your vehicle is equipped with a front passenger occupant classification sensor as a part of
the supplemental restraint system. This sensor is equipped in the front passenger's seat
cushion. This sensor measures the electrostatic capacity of the front passenger's seat. The
SAS unit is designed to prevent the front pass enger front and side air bags and seat belt
pretensioner system from deploying if the front passenger air bag deactivation indicator
light turns on.
To reduce the chance of injuries caused by de ployment of the front passenger air bag, the
system deactivates the front passenger front and side air bags and also the seat belt
pretensioner system when the front passenger air bag deactivation indicator light turns on.
Refer to the following table for the front pa ssenger air bag deactivation indicator light
illumination conditions.

This system shuts off the front passenger front and side air bags and seat belt pretensioner
system, so make sure the front passenger air bag deactivation indicator light turns on
according to the following table.

The air bag/front seat belt pretensioner system warning light flashes and the front passenger
air bag deactivation indicator light illuminates if the sensors have a possible malfunction. If
this happens, the front passenger front and side air bags and seat belt pretensioner system
will not deploy.
Front passenger air bag de activation indicator light
This indicator light turns on to remind you that the front passenger front and side air bags
and seat belt pretensioner wi ll not deploy during a collision.

deactivation indicator light on/ off condition chart indicates.
If the front passenger air bag deactivation indi cator light does not turn on when the ignition
is switched ON and does not turn on as indicated in the front passenger air bag deactivation
indicator light on/off condition chart, do not allow an occupant to sit in the front passenger
seat and consult an Authorized Mazda Dealer as soon as possible. The system may not work
properly in an accident.
WA R N I N G
Do not allow an occupant in the front passenger's seat to sit with a posture which makes it
difficult for the front passenger occupant classification sensor to detect the occupant
correctly:
Sitting in the front passenger's seat with a posture which makes it difficult for the front
passenger occupant classification sensor to dete ct the occupant correctly is dangerous. If the
front passenger occupant classification sensor ca nnot detect the occupant sitting on the front
passenger's seat correctly, the front passeng er front and side air bags and pretensioner
system may not operate (non-deploy) or they may operate (deploy) accidentally. The front
passenger will not have the supplementary prot ection of the air bags or the accidental
operation (deployment) of the air bags could result in serious injury or death.
Under the following conditions, the front passenger occupant classification sensor cannot
detect a passenger sitting on the front passenger's seat correctly and the deployment/
non-deployment of the air bags cannot be controlled as indicated in the front passenger air
bag deactivation indicator light on/off condition chart. For example:

The front passenger front and side air bags and seat belt pretensioner systems will deactivate
if the front passenger air bag deactivation indicator light turns on.
CAUTION
 To assure proper deployment of the front air bag and to prevent damage to the sensor in
the front seat cushion:
 Do not place sharp objects on the front seat cushion or leave heavy luggage on them.
 Do not spill any liquids on the fr ont seats or under the front seats.
 To allow the sensors to function pr operly, always perform the following:
 Adjust the front seats as far back as possibl e and always sit upright against the seatbacks
with seat belts worn properly.
 If you place your child on the front passe nger seat, secure the child-restraint system
properly and slide the front passenger seat as far back as possible (page 2-59).
NOTE
The system requires about 10 seconds to alternate between turning the front passenger
front and side air bags and seat belt pretensioner system on or off.
The front passenger air bag deactivation indicator light may turn on repeatedly if luggage
or other items are put on the front passenger se at, or if the temperature of the vehicle's
interior changes suddenly.
The front passenger air bag deactivation indicator light may turn on for 10 seconds if the
electrostatic capacity on the front passenger seat changes.
The air bag/front seat belt pr etensioner system warning light might turn on if the front
passenger seat receives a severe impact.
If the front passenger air bag deactivation indicator light does not turn on after installing
a child-restraint system on the front passenger seat, first, re-install your child-restraint
system according to the procedure in this owner's manual. Then, if the front passenger air
bag deactivation indicator light still does not turn on, install the child-restraint system on
the rear seat and consult an Authorized Mazda Dealer as soon as possible.
If the front passenger air bag deactivation indicator light turns on when an occupant is
seated directly 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 remains turned on, 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.
