WARNING
Hot Air Bag Inflators:
Hot air bag inflators are dangerous. Immediately after inflation, the inflators in the
steering wheel, dashboard, seatbacks, or the front and rear window pillars and along
the roof edge are very hot. You could get burned. Don't touch the internal components
of the air bag modules after the bags have inflated.
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. Front 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. An Authorized Mazda
Dealer can provide the special care needed in the removal and installation of front
seats. It is important to protect the side and curtain air bag wiring and connections to
assure that the bags do not accidentally deploy and that the seats retain an
undamaged air bag connection.
CAUTION
To prevent damage to the side and curtain air bag wiring, don't place luggage or other
objects under the front seats.

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, in the outboard sides of the front seatbacks and the front
and rear window pillars, along the roof edge. They are out of sight until activated.

*1 The driver's seat slide position sensor determines whether the driver's seat is fore or aft
of a reference position. The sensor is designed to control the deployment of the driver's
air bag depending on how close the driver's seat is to the steering wheel.
*2 The buckle switches on the front seat belts determine whether or not the front seat belts
are securely fastened and further control the deployment of the air bags on the front
seats.
*3 The front, dual stage air bags control air bag inflation in two energy stages. During an
impact of moderate severity the front air bags deploy with lesser energy, whereas
during more severe impacts, they deploy with more energy.
Deployment of the front air bags may differ between the driver and the front passenger
depending on the driver's seat position and front seat belt usage, which allow for further
controlling of the system.

qHow the Air Bags Work
When air bag crash sensors detect a frontal or side 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 systems.
The front air bags will deploy
only on the frontal impact.
The side air bag will deploy only on the side
the vehicle receives the force of the impact.
The curtain air bag will deploy only on the side
the vehicle receives the force of the impact.
The side and curtain air bags will deploy
together on the same side.

lVehicle roll-over may not provide
enough side force to deploy the side
and curtain air bags.
lSide impacts with two-wheeled
vehicles may not provide enough force
to deploy the side and curtain air bags.
Non-activation of side and curtain air
bags
The side and curtain air bags will not
normally inflate in the following cases:
lCollision from the rear.
lCollision from the front, but it may
deploy the front air bags.

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 seat, 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 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.
Your Mazda will perform best with fuel listed in the table.
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.
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.
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.
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”.
Vehicle damage and drivability problems resulting from the use of the following may not
be covered by the Mazda warranty.
lGasohol containing more than 10% ethanol.
lGasoline or gasohol containing methanol.
lLeaded fuel or leaded gasohol.
