MAZDA MODEL MX-5 2020 (in English) Workshop Manual

Do not touch the components of the supplemental restraint system after the air bags have
inflated:
Touching the components of the supplemental restraint system after the air bags have
inflated is dangerous. Immediately after inflation , they are very hot. You could get burned.
Never install any front-end equipment to your vehicle:
Installation of front-end equipment, such as frontal protection bar (kangaroo bar, bull bar,
push bar, or other similar devices), snowplow , or winches, is dangerous. The air bag crash
sensor system could be affected. This could cause air bags to inflate unexpectedly, or it could
prevent the air bags from inflating during an accident. Occupants could be seriously injured.
Do not modify the suspension:
Modifying the vehicle suspension is dangerous. If the vehicle's height or the suspension is
modified, the vehicle will be unable to accurately detect a collision resulting in incorrect or
unexpected air bag deployment and the possibility of serious injuries.
Do not modify a door or leave any damage unrepaired. Always have an Authorized Mazda
Dealer inspect a damaged door:
Modifying a door or leaving any damage unrepai red is dangerous. Each door has a side crash
sensor as a component of the supplemental restraint system. If holes are drilled in a door, a
door speaker is left removed, or a damaged d oor 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 impa ct correctly, the side air bags and the 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 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 seats. It is important to protect the air bag wiring and
connections to assure that the bags do not accidentally deploy, and that the passenger
occupant classification system and the seats retain an undamaged air bag connection.
Do not place luggage or other objects under the seats:
Placing luggage or other objects under the 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 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 seats, front dashboard, the steering wheel, containing
air bag parts or sensors is dangerous. These pa rts 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 resul t. 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 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.
Vehicles with a passenger air bag have a warning label attached as shown in the
following.

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.
▼Seat Belt Pretensioners
The seat belt pretensioners are designed to deploy in moderate or severe frontal, near frontal
collisions.
In addition, during a side collision, the pretensioner operates . The pretensioners operate
differently depending on what types of air bags are equipped. F or more details about seat
belt pretensioner operation, refer to the SRS Air Bag Deployment Criteria (page 2-46).
▼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 Ba g Deployment Criteria"
(page 2-46).
(Except Mexico)
The driver's dual-stage air bag controls air bag inflation in two energy stages. During an
impact of moderate severity, the driver's air bag deploys with lesser energy, whereas during
more severe impacts, it deploys with more energy.

▼Passenger Air Bag
The passenger air bag is mounted in the passenger dashboard.
The inflation mechanism for the passenger air bag is the same as the driver's air bag.
For more details about air bag de ployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-46).
In addition, the passenger air bag is designed to only deploy w hen the passenger occupant
classification sensor detects a passenger sitting on the passen ger's seat. For details, refer to
the passenger occupant classification system (page 2-49).
▼Side Air Bags
The side air bags are mounted in the outboard sides of the seatbacks.
When the air bag crash sensors detect a side impact of greater than moderate force, the
system inflates the side air bag only on the side in which the vehicle was hit. The side air
bag inflates quickly to reduce injury to the driv er or passenger's head and chest caused by
directly hitting interior pa rts such as a door or window.
For more details about air bag de ployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-46).
In addition, the passenger side air bag is designed to only dep loy when the passenger
occupant classification sensor detects a passenger sitting on t he passenger's seat. For details,
refer to the passenger occupant classification system (page 2-4 9).

Limitations to SRS Air Bag
In severe collisions such as those described previously in "SRS Air Bag Deployment
Criteria", the applicable SRS air bag equipment will deploy. However, in some accidents,
the equipment may not deploy depending on the type of collision and its severity.

Limitations to fron t/near front collision detection:
The following illustrations are examples of front/near front co llisions that may not be
detected as severe enough to deploy the SRS air bag equipment.
