WARNING
Installation of Front-End Equipment:
Installation of front-end equipment, such as frontal protection bar (kangaroo bar, bull
bar, push bar, etc.), 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. Never install any front-end equipment to your vehicle.
Suspension Adjustment:
Adjusting the vehicle suspension is dangerous. If the vehicle's height or the
suspension is changed, the vehicle will be unable to accurately detect a collision
resulting in incorrect or unexpected air bag deployment and the possibility of serious
injuries.
Modification of 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. Don't make any
modifications to the supplemental restraint system. This includes installing trim,
badges, or anything else over the air bag modules. It also includes installing extra
electrical equipment on or near system components or wiring.
NOTE
lWhen 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.
lShould 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.

Air Bag System Description
The supplemental restraint systems (SRS) have two basic subsystems:
lThe air bag system with inflators and air bags.
lThe electrical system with crash sensors and diagnostic module.
The air bags are mounted in the following locations: the center of the steering wheel, the
passenger-side of the dashboard. They are out of sight until activated.
The passenger air bag has a deactivation switch located on the center console (page 2-23).

module (SAS unit)
Inflators and air bags Crash sensor

How the Air Bags Work
When air bag crash sensors detect a frontal impact of greater than moderate force, an
electrical current is sent to the inflators.
Gases are produced to inflate the air bags and after the inflation, the air bags quickly
deflate.
The air bags will function only once. After that, the air bags will not work again and
must be replaced.
Only an Authorized Mazda Dealer can replace the system components.

lRear-ending or running under a truck's
tail gate may not provide the stopping
force necessary for air bag deployment.
Non-activation of air bags
Air bags will not normally inflate in the
following cases:
lCollision from the rear.
lImpact to the side.
lVehicle roll-over.
qConstant Monitoring
The following components of the air bag
systems are monitored by a diagnostic
system:
lSAS unit
lCrash sensor
lAir bag modules
lSeat belt pretensioners
lRelated wiring
lPassenger air bag deactivation switch
A diagnostic module continuously
monitors the systems' readiness. This
begins when the ignition switch is turned
to the ON position and continues while
the vehicle is being driven.
q Air Bag/Seat Belt Pretensioner
System Warning Light
If the air bag/seat belt pretensioner system
is normal, the warning light illuminates
when the ignition switch is turned to the
ON position or after the engine is cranked.
After about 6 seconds it goes out.

A system malfunction is indicated when
the warning light constantly flashes,
illuminates or doesn't illuminate at all
when the ignition switch is turned to the
ON position. If any of these occur, consult
an Authorized Mazda Dealer as soon as
possible. The system may not work in an
accident.
WARNING
Self-Servicing the Air Bag/
Pretensioner Systems:
Self-servicing or tampering with the
systems is dangerous. An air bag/
pretensioner could accidentally
activate or become disabled. This
could cause serious injuries. Never
tamper with the systems and always
have an Authorized Mazda Dealer
perform all servicing and repairs.
qMaintenance
The air bag systems do not require regular
maintenance. But if any of the following
occurs, take your vehicle to an Authorized
Mazda Dealer as soon as possible:
lThe air bag system warning light
flashes.
lThe air bag system warning light
remains illuminated.
lThe air bag system warning light
remains off when the ignition switch is
turned to the ON position.
lThe air bags inflate.
WARNING
Damaged Air Bag Sensors:
Driving with damaged air bag sensors
is dangerous. A collision, even one not
strong enough to inflate the air bags,
could damage the sensors. If there was
a subsequent collision, a damaged
sensor would not inflate the air bags.
Always have an Authorized Mazda
Dealer inspect the air bag systems
after a collision.
Removing Interior Parts:
Removing any components such as the
front dashboard, the steering wheel or
parts containing air bag parts or
sensors is dangerous. These parts
contain essential air bag parts. The air
bag could accidentally activate and
cause serious injuries. Always have an
Authorized Mazda Dealer remove
these parts.
Air Bag Disposal:
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 can
result. Ask an Authorized Mazda
Dealer how to safely dispose of an air
bag or how to scrap an air bag
equipped vehicle.

Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use ONLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a minimum.
MX-5/Miata
Your Mazda will perform best with fuel listed in the table.
FuelOctane Rating*(Anti-knock index)
Premium unleaded fuel 91 [ (R+M)/2 method] or above (96 RON or above)
* U.S. federal law requires that octane ratings be posted on gasoline station pumps.
You may use a regular unleaded fuel with an Octane Rating from 87 to 90 (91 to 95 RON)
but this will slightly reduce performance.
Fuel with a rating lower than 87 octane (91 RON) could cause the emission control system
to lose effectiveness. It could also cause engine knocking and serious engine damage.
MAZDASPEED MX-5
Fuel Octane Rating*(Anti-knock index)
Premium unleaded fuel 91 [ (R+M)/2 method] or above (96 RON or above)
* U.S. federal law requires that octane ratings be posted on gasoline station pumps.
CAUTION
lUSE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic converter or the oxygen sensor. The lead will
accumulate on the oxygen sensor and the catalyst inside the converter. This will result
in a malfunction of the emission control system, causing poor performance.
lYour vehicle can only use oxygenated fuels containing no more than 10% ethanol by
volume. Damage to your vehicle may occur when ethanol exceeds this
recommendation, or if the gasoline contains any methanol. Stop using gasohol of any
kind if your vehicle engine is performing poorly.
lNever add fuel system additives. Never add cleaning agents other than those specified
by Mazda. Other cleaning agents and additives may damage the system. Consult an
Authorized Mazda Dealer.
l(MAZDASPEED MX-5)
Never use fuel other than premium unleaded fuel for your vehicle. Use of other fuel
could cause poor engine performance and serious engine knocking.
Gasoline blended with oxygenates such as alcohol or ether compounds are generally
referred to as oxygenated fuels. The common gasoline blend that can be used with your
vehicle is ethanol blended at no more than 10%. Gasoline containing alcohol, such as
ethanol or methanol, may be marketed under the name “Gasohol ”.
