1_ IMPORTANT PRELIMNARY INFORMATION
BREAK-IN PERIOD
Following a few simple precautions for the first few
handfed miles can add to the future performance,
economy and long life of your car.
• Do not race the engine.
• Drive at varying speeds, trying not to "strain" the
engine.
• Avoid hard stops, except in emergencies.
This will allow the brakes to seat properly.
After 2,000 miles of driving, your vehicle's first
maintenance should be performed at your Mazda dealer.
1- 1
WARRANTIES
Please refer to the separate warranty and service book,
as furnished with each Mazda vehicle for details.
FUEL REQUIREMENTS
Your new Mazda is designed to operate only on
UNLEADED GASOLINE of approximately 91 Research
Octane or higher when the engine is adjusted to
factory recommended specifications. The gasoline
should also have a Motor Octane of at least 83 .
Unleaded gasoline
is essential for proper emission
control system operation, and it will minimize spark
plug fouling.
Caution:
Never use fuel system cleaning agents
added to the fuel
tank or added to the carburetor. These materials may
be detrimental to the catalytic converter.
Operation In Foreign Countries
If you plan to drive your vehicle outside the United
States and Canada, check the quality of gasoline
available in area you expect to visit. In some count-
ries are so low in octane rating that excessive knock-
ing and lead fouling of spark plugs may result from
their use.
Also, if leaded fuels are used in vehicle with the
CATALYTIC CONVERTER, it can damage the con-
verter and can cause other related problem.

OPERATING CAUTION
Your Mazda Emission Control System can produce
oonsiderable heat. T0 - avoid problems, please be sure
to observe the following precaution:
Do
not operate or park the vehicle in areas where
flammable materials such as
dry grass may come
into contact with the hot exhaust system.
Under certain weather conditions, these materials
could be ignited by a hot exhaust system.
Failure to observe the above precaution could result
in damage to your vehicle.
CATAL VTIC CONVERTER
The catalytic converter is an emission control device
added
to the exhaust system. The converter has pellets
coated with a catalytic material containing platinum
and palladium. These material stimulate a chemical
reaction
that assists in converting carbon monoxide
(CO) and hydrocarbons (He) into harmless carbon
dioxide
and water vapor.
OPERATING PRECAUTIONS FOR CARS
EQUIPPED WITH
CATAL VTIC CONVERTER
To help av oi d overheating the exhaust system and to
maintain catalylic converter performance, the follow-
ing precautions should be observed:
1 -2
1. UNLEADED FUEL only must be used.
2.
00 not park the car over or near inflammable
objects such
as dry grass.
3.
00 not operate the vehicle when there are signs
of engine malfunction, such
as engine misfire or
other noticeable loss of performance.
4. Do
not misuse or abuse the vehicle engine.
Examples
of misuse are coasting with ignition off,
going
down steep grades in gear with ignition off
and operating with the
choke knob pulled out
when the engine is already warm.
5. Do
not operate extended high speed idling of the
engine (5 minutes or more) by using the choke when
the engine
is cold.

6. Avoid th e fuel tank from becoming empty.
7. Do not modify or tamper with any part of
the
engine or emission control system. All inspections
and adjus
tments require a qualified technician.
Failure
to observe the above precautions could result
in damages to the catalytic converter and your vehicle.
If
the catalytic converter should begin to overheat,
the heat hazard warning light will come on.

c ':--' H
Heat hazard warning light
1-3
What to do:
1. Reduce speed, park your car in a safe spot where
there are
no flammable materials and turn the engine
off . Wait 5 minutes or more.
2. Check spark plug wire connections. If any
of them
are disconnected, reconnect them properly.
3.
If the spark plug wires are properly connected, have
your author ized Maz da dealer locate and correct
the trouble as soon as possible. Park your car until
the heat hazard warning light goes out and drive
your vehicle to a dealer slowly.
This warning light also comes on when
the ignition
switch
is turned on (as a check of bulb operation),
and should
go out after the engine has been started.
EMISSION CONTROL SYSTEM LAWS
Any modification of the original'equipment emissions
control systems prior
to the first sale and registra·
tion of a new vehicle is su bject to penalties under
Federal law in
the United States. Any such modifi-
cations made thereafter may also be subject to penal-
t ie s in some states.

ENGINE EXHAUST GAS CAUTION
(CARBON MONOXIDE)
Engine exhilust gases, though colorless and odorless,
contain carbon monoxide, which is dangerous or even
lethal if inhaled.
1. If at any time you suspect that exhaust fumes are
entering
the passenger compartment, have the source
located and corrected as soon as possible.
2. If it is necessary to drive under such conditions ,
do so only with all windows fully open.
3. Do not operate the engine in confined areas such as
garages
or other closed areas any more than needed
to move vehicle in or out of area.
1- 4
4. When the vehicle is stopped in an unconfined area
with th e engine running for more than a short length
of time, adjust the heating or cooling system to draw
outside air into the vehicle.
REGISTRATION IN FOREIGN COUNTRIES
If you plan to register your Mazda in another countries,
first make sure
that it meets that country's regulations
(e.g. safety standards, air pollution control standards
etc .'.
We advise you to consult us through authorized Mazda
dealer before acting.

removed.
SEAT BEL T/SAFETY RESTRAINT SYSTEMS
To help protect you and your passengers from injuries
in the event of an accident, your Mazda is equipped
with seat lap-shoulder belts.
The seat lap-shoulder belts are equipped with re-
tractors which have inertia locks. The retractors
keep the belts out of the way for convenient entrance
2-5
and exit from the vehicle. The inertia locks allow
the belts to remain slack, for comfort, until a decel-
eration force occurs, such as in a sudden stop or
collision. At that time, the retractors automatically
lock the belts in position and restrain the seat
occupants from being thrown forward.
Note:
1. The
retractor will lock automatically if the belt is
pulled out quickly, or if the car inclines to an angle
greater than 25 degrees.
2. Always adjust the seat to the position in which you
will drive before fastening the seat belts.

SEAT BELTS
To Fasten Front Seat Belts:
1. Grasp the buckle end and tongue plate.
2. Slowly pull the lap-shoulder belt webbing out.
3. If the lap belt is not far enough to permit buckling.
hold the tongue plate at right angles to the lap
belt and pull the lap bell webbing until the desired
length is obtained.
4. Insert the tongue plate into the open end of the
buckle. An audible click should sound, indicating
the belt is securely locked.
5. Position the lap belt across your lap as LOW ON
THE H IPS as possible. To reduce the risk of
sliding under the belt during an accident, adjust
to a SNUG FIT by pulling the belt extending from
the tongue plate. Tne belt retractor is designed
to automatically take up excess webbing and main-
tain tension on the shoulder belt.
2- 6
To Fasten Rear Seat Belts:
1. Grasp the buckle end and longue plate.
2. In one continuous motion pull the belt webbing
(tongue side) ac ross lap far enough to permit buckl·
ing. If the pulling motion is interrupted while
extending the blet, it may be necessa
ry to fully
retract the belt
to release the lock mechanism, so
the belt can be pulled out to the proper length.
3. Insert the tongue plate into the open end of the
buckle.
4. The retractor will automatically take up excess
webbing.
To Unfasten Belts:
To unfasten the belts, depress the push button in
the center of the buckle.
Proper Use and Car. of Seat Belts
To gain maximum effectiveness from the seat belt
system, please follow these
suggestions-
1. Use the seat belts at all times -even on short trips.
2. Never use the same belt for more than one person
at a time.
3. The use
of shOUlder belts is not recommended
for passengers under six years old
or weighing
less Ihan 50 pounds (25 kg), as this increases the
chance of neck injury in an accident.

4. Avoid wearing belts in a twisted condition.
5. Keep sharp edges and damaging objects away from
belts, and
other parts of restraint system.
6. Periodically inspect belt webbings, buckles, anchors
and
other parts for signs of wear, damage or weak-
ness. Replace questionable parts immediately.
7.
To clean the belt webbing, wash it with a mild
soap
or mild detergent.
Do
not use such materials as carbon tetrachloride
or naphtha, etc. Bleaching or redyeing is not rec-
ommended.
8. No modifications
or additions should be made by
the user.
