MAZDA MODEL MX-5 MIATA 2018 Service Manual

If your vehicle is also equipped with a passenger occupant classification system, refer
to the Passenger Occupant Classification System (page 2-40) for details.
If your vehicle is equipped with a passenger occupant classification system, the passenger
air bag deactivation indicator light illuminates for a specifie d time after the ignition is
switched ON.


Small children mu st be protected by a child-restraint system as stipulated by law in every
state and province. In certain s tates and provinces, larger children must use a child-restraint
system (page 2-15).

Carefully consider which child-restraint system is necessary fo r your child and follow the
installation directions in this Owner's Manual as well as the c hild-restraint system
manufacturer's instructions.
Do not use a child-restraint system which employs an upper teth er because there is no
appropriate means to anchor the tether.
WA R N I N G
Seat belts must be worn in air bag equipped vehicles:
Depending only on the air bags for protection during an accident is dangerous. Alone, air
bags may not prevent serious injuries. The appr opriate air bags can be expected to inflate
only in the first accident, such as frontal, near frontal or side collisions that are at least
moderate. Vehicle occupants shou ld always wear seat belts.

Always make sure the passenger air bag deactivation indicator light is illuminated when
using a child-restraint system (With Passenger Occupant Classification System):
Seating a child in a child-restraint system that is installed on the passenger seat with the
passenger air bag deactivation indicator light not illuminated is extremely dangerous. In an
accident, an air bag could inflate and cause seri ous injuries or even death to the child seated
in the child-restraint system. Always make su re the passenger air bag deactivation indicator
light is illuminated.
Refer to Occupant Classification System on page 2-40.

Do not sit too close to the driver and passenger air bags:
Sitting too close to the driver and passenger air bag modules or placing hands or feet on them
is extremely dangerous. The driver and passeng er air bags inflate with great force and speed.
Serious injuries could occur if someone is too close. The driver should always hold onto only
the rim of the steering wheel. The passenger should keep both feet on the floor. Seat
occupants should adjust their seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.
Do not sit too close to a door or lean against doors in vehicles with side air bags:
Sitting too close to the side air bag module s or placing hands on them is extremely
dangerous. A side air bag inflates with great force and speed directly out of the outboard
shoulder of the seat and expands along the door on the side the car is hit. Serious injury could
occur if someone is sitting too close to the d oor or leaning against a window in the seats.
Furthermore, sleeping up against the door or hanging out the driver-side window while
driving could block the side air bag and eliminate the advantages of supplemental
protection. Give the side air bags room to work by sitting in the center of the seat while the
vehicle is moving 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 extremely dangerous. The side air bags
inflate with
great force and speed directly expanding along th e door on the side the car is hit. Serious
injury could occur if someone is sitting too clos e to the door. Give the side air bags room to
work by sitting in the 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 passenger air bags deploy:
Attaching an object to the driver and passenger air bag modules or placing something in
front of them is dangerous. In an accident, an object could interfere with air bag inflation and
injure the occupants.
Do not attach objects on or around the area where a side air bag deploys:
Attaching objects to the seat in such a way as to cover the outboard side of the seat in any
way is dangerous. In an accident the object could interfere with the side air bag, which
inflates from the outboard side of the seats, impe ding the added protection of the side air bag
system or redirecting the air bag in a way that is dangerous. Furthermore, the bag could be
cut open releasing the gas.
Do not hang net bags, map pouches or backpacks with side straps on the seats. Never use
seat covers on the seats. Always keep the side air bag modules in your seats free to deploy in
the event of a side collision.

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 inflati ng 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 accura tely 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 restr aint 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 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 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 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 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 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.
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 colli sion, the pretensioner operates on the side in which the
collision occurs. The pretensioners operate differently dependi ng on what types of air bags
are equipped. For more details about seat belt pretensioner operation, refer to the SRS Air
Bag Deployment Criteria (page 2-37).
▼ 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 main
ly to the driver's head or chest
caused by directly hitting the steering wheel.
For more details about air bag de ployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-37).
(With Passenger Occupant Classification System)
The driver's dual-stage air bag controls air bag inflation in t wo 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 deployment, refer to "SRS Air Ba
g Deployment Criteria"
(page 2-37).
(With Passenger Occupant Classification System)
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 2-40).

▼Side Air Bags
The side air bags are mounted in the outboard sides of the seat
backs.
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 2-37).
(With Passenger Occupant Classification System)
In addition, the passenger side bag is designed to only deploy when 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 2-40).
