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 storage areas 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 storage areas. It also includes installing
extra electric 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.
To prevent damage to the side and curtain air bag wiring, don’t place luggage or other
objects under the front seats.

SRS Air Bags
Form No. 8R65-EA-03C
The supplemental restraint systems (SRS) have two basic subsystems:
•The air bag system with inflators and air bags.
•The electric 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.
*1The 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.
*2The 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.
*3The 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.

How 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 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 front air bags will deploy
only on the frontal impact.
The side and curtain air bags will deploy together
on the same side.

begins when the ignition switch is turned
to the ON position and continues while
the vehicle is being driven.

Air Bag/Front Seat Belt
Pretensioner System Warning
Light
If the air bag/front seat belt pretensioner
system is OK, the warning light comes on
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, stays
on or doesn’t come on 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.

Maintenance
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:
•The air bag system warning light
flashes.
•The air bag system warning light stays
on.
•The air bag system warning light stays
off when the ignition switch is turned
to the ON position.
•The air bags inflate.
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.

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 and Engine Exhaust Precautions
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.
*U.S. federal law requires that octane ratings be posted on gasoline station pumps.
You may use a regular unleaded fuel with 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.
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.
•Gasohol containing more than 10% ethanol.
•Gasoline or gasohol containing methanol.
•Leaded fuel or leaded gasohol.
Fuel Requirements
Fuel Octane Rating* (Anti-knock index)
Premium unleaded fuel 91 [ (R+M)/2 method] or above (96 RON or above)
•USE 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.
•Your 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.
•Never 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.

Use tires of the correct size
specified for your Mazda on all
four wheels.
Use tires of the same
manufacturer, brand and tread
pattern on all four wheels.
Do not mix worn tires.
•The DSC may not operate correctly
when using tire chains or the
temporary spare tire.
•If repair or replacement of the
steering or other surrounding
equipment is necessary, have it done
at an Authorized Mazda Dealer. If
the center position of the steering
deviates, the DSC may not operate
correctly because there is a sensor
in the steering which detects driving
conditions.
CAUTION

The tire pressure monitoring system
(TPMS) monitors the pressure for each
tire.
If tire pressure is too low or too high in
one or more tires, the system will inform
the driver via the warning light in the
instrument panel and the warning beep.
The tire pressure sensors installed on each
wheel send tire pressure data by radio
signal to the receiver unit in the vehicle.
TPMS does not alleviate your need to
check the pressure and condition of all
four tires before you drive each day.
Tire Pressure Monitoring
System*
Tire pressure sensors
•When the tire pressure monitoring
system warning light is lit, one or
more of your tires is significantly
under-inflated. You should stop and
check your tires as soon as possible,
and inflate them to the proper
pressure as indicated on the
vehicle’s tire information placard.
Driving on a significantly under-
inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and
may affect the vehicle’s handling
and stopping ability. Each tire,
including the spare, should be
checked monthly when cold and set
to the recommended inflation
pressure as specified in the vehicle
placard and owner’s manual.
•To avoid false readings, the system
samples for a little while before
indicating a problem. As a result it
will not instantaneously register a
rapid tire deflation or blow out.
NOTE
This device complies with part 15 of
the FCC Rules. Operation is subject to
the following two conditions: (1) This
device may not cause harmful
interference, and (2) this device must
accept any interference received,
including interference that may cause
undesired operation.
