Octane recommendations
[SV08800( ALL)05/95]
Your engine is designed to use fuel with an
octane rating of 87. In most cases it is not
necessary to use a fuel with an octane rating
higher than 87. At service stations, the octane
rating is displayed in a label on the pumps.
[SV08900( ALL)05/95]
one inch art:0060001-C[SV09100( ALL)05/95]
Using a fuel with a lower octane rating can
cause persistent and heavy knocking, which can
damage the engine.
[SV09200( ALL)05/95]
Do not be concerned if your vehicle sometimes
knocks lightly when you drive up a hill or when
you accelerate. However, see your dealer or a
qualified service technician if persistent heavy
knocking occurs because this can damage the
engine.
[SV09350( ALL)05/95]
If your vehicle has problems with starting, rough
idle or hesitation problems when the engine is
cold, it may be caused by fuel with low
volatility. Try a different brand of fuel. If the
condition persists, see your dealer or a qualified
service technician.
[SV09800( ALL)05/95]
Gasolines for clean air
[SV09900( ALL)05/95]
Fuels in certain areas of the country are required
to contain oxygenates to improve air quality.
Common oxygenates are ethanol or grain alcohol
(blended at no more than 10%), methanol or
wood alcohol (blended at no more than 5% with
cosolvents and additives), and MTBE or methyl
tertiary butyl ether (blended at no more than
15%).

Your vehicle's coolant protects your engine from
overheating in the summer and from freezing in
the winter. Check the level of the coolant at least
once a month. Simply look at the engine coolant
reservoir located in the engine compartment. To
locate the reservoir, see the diagram of your
vehicle's engine underEngine Type, in this
chapter.
*
[SV17850( ALL)05/95]
The coolant additives also protect the entire
cooling system from internal passageway
corrosion and these additives lubricate the water
pump. The coolant should be serviced as noted
in theMaintenance Schedule and Recordbooklet.

Ford Premium Cooling System Fluid is an
optimized formula that will protect all metals
and rubber elastomers used in Ford engines for
four years or 50,000 miles (80,000 km). It is not
necessary and not recommended to use
supplemental coolant additives in your gasoline
powered vehicle. These additives may harm
your engine cooling system. Follow the
recommended service interval for changing your
engine coolant.
*
[SV19450( ALL)04/94]
NOTE: When you change or add engine
coolant, it is important to maintain
your engine coolant concentration
between 40%(-11ÊF [-24ÊC]) and 60%
(-62ÊF [-52ÊC]),depending on your local
climate conditions. Below 40% you will
lose freeze protection and above 60%
your engine may overheat on a warm
day.
[SV19460( ALL)12/94]
NOTE: The use of an improper coolant may
void your warranty for the engine
cooling system. Use only a premium
nationally recognized brand name
engine coolant. Do not use alcohol,
methanol antifreeze or engine coolant
mixed with alcohol or methanol
antifreeze. If you do not use the proper
coolant, the aluminum radiator on your
vehicle will corrode.

Leave the engine coolant in all year. Make sure
that the coolant will not freeze at the
temperature level in which you drive during
winter months. Keep a mixture of engine coolant
in your engine that has a protection rating of at
least-34ÊF (-37ÊC), orwhatever protection rating
is appropriate for the climate in which you live.

Information About Tire Quality Grades
*
[SV28200( ALL)01/95]
New vehicles are fitted with tires that have their
Tire Quality Grade (described below) molded
into the tire's sidewall. These Tire Quality
Grades are determined by standards that the
United States Department of Transportation has
set.
*
[SV28250( ALL)01/95]
Tire Quality Grades apply to new pneumatic
tires for use on passenger cars. They do not
apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires
with nominal rim diameters of 10 to 12 inches or
limited production tires as defined in Title 49
Code of Federal Regulations Part 575.104(c)(2).
*
[SV28300( ALL)01/95]
U.S. Department of Transportation Ð Tire
quality grades:The U.S. Department of
Transportation requires Ford to give you the
following information about tire grades exactly
as the government has written it.
%*
[SV28399( ALL)01/95]
Treadwear
*
[SV28400( ALL)01/95]
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course. For example, a tire
graded 150 would wear one and one-half (1 1/2)
times as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteristics
and climate.

Emission Control System
*
[SV52500( ALL)05/95]
Your vehicle is equipped with a catalytic
converter which enables your vehicle to comply
with applicable exhaust emission requirements.
*
[SV52550( ALL)05/95]
RWARNING
Exhaust leaks may result in the entry of
harmful and potentially lethal fumes into
the passenger compartment. Under
extreme conditions excessive exhaust
temperatures could damage the fuel
system, the interior floor covering, or
other vehicle components, possibly
causing a fire.
*
[SV52600( ALL)05/95]
To make sure that the catalytic converter and the
other emission control parts continue to work
properly:
*
[SV52700( ALL)01/95]
q
Use only unleaded fuel.
*
[SV52800( ALL)01/95]
q
Avoid running out of fuel.
*
[SV52900( ALL)01/95]
q
Do not turn off the ignition while your

Have the services listed in theMaintenance
Schedule and Recordbooklet performed
according to the specified schedule. The
scheduled maintenance services are required
because they are considered essential to the
life and performance of your vehicle and to
its emissions system.

[SV53075( ALL)03/95]
In general, maintenance, replacement, or service
of the emissions control devices or systems in
your new Ford Motor Company vehicle or
engine may be performed at your expense by
any automotive repair establishment or
individual using automotive parts equivalent to
those which your vehicle or engine was
originally equipped.
*
[SV53150( ALL)05/95]
Ford strongly recommends the use of genuine
Ford replacement parts. If other than Ford or
Motorcraft parts or Ford authorized
remanufactured parts are used for maintenance
replacements or for the service of components
affecting emissions control, such non-Ford parts
should be equivalent to genuine Ford Motor
Company parts in performance and durability. It
is the owner's responsibility to determine the
equivalency of such parts. Please consult your
warranty booklet for complete warranty
information.
*
[SV53175( ALL)05/95]
RWARNING
Do not park, idle, or drive your vehicle in
dry grass or other dry ground cover. The
emission system heats up the engine
compartment and exhaust system, which
can start a fire.
*
[SV53200( ALL)05/95]
Watch for fluid leaks, strange odors, smoke, loss
of oil pressure, the charge warning light, the
check engine light, or the temperature warning
light. These sometimes indicate that the emission
system is not working properly.
*
[SV53300( ALL)01/95]
Do not make any unauthorized changes to your
vehicle or engine. Changes that cause more
unburned fuel to reach the exhaust system can
increase the temperature of the engine or
exhaust system.
