Never get under a vehicle while it is
supported only by a jack. If you must work
under a vehicle, use safety stands.
*
[SV02200(ALL)06/95]
q
Keep all lit cigarettes and other smoking
materials away from the battery and all
fuel-related parts.
*
[SV02500(ALL)03/95]
If you disconnect the battery, the engine must
ªrelearnº its idle conditions before your vehicle
will drive properly. To find out how the engine
does this, seeBatteryin this chapter.

To close the hood, raise it so that the support
rod comes away from the slotted hole in the
hood. Place the support rod in its retaining clip
and close the hood with enough force to make it
latch. Be sure to oil the hood latch every six
months to maintain smooth operation.
*
[SV03900(ALL)05/90]
Always attempt to lift the hood after closing to
be sure it is securely latched.

Cleaning the Engine
*
[SV05590(ALL)04/95]
A clean engine is more efficient because a
buildup of grease and dirt acts as an insulator,
keeping the engine warmer than usual.
*
[SV05592(ALL)07/95]
q
Extreme care must be used if a power washer
is used to clean the engine. The high pressure
fluid could penetrate sealed parts and
assemblies causing damage or malfunctions.
[SV05594(ALL)08/95]
q
In order to avoid possible cracking of the
engine block, do not spray a hot engine with
cold water.
[SV05596(ALL)06/95]
q
The alternator and air intake must be
covered. Covering these components will help
prevent water damage.
*
[SV05598(ALL)04/95]
q
Never wash or rinse the engine while it is
running. Water getting into the engine may
cause internal damage.

[SV06950(ALL)03/91]
To replace and secure the fuel cap; place it in
position and rotate it clockwise until it clicks
(ratchets). Doing so will not damage or break
the fuel cap. The ratcheting mechanism allows
the fuel cap to be sealed without overtightening.
*
[SV06990(ALL)07/95]
If you lose the fuel cap, replace it with an
authorized Motorcraft or equivalent part.
%*
[SV07000(ALL)05/95]
RWARNING
If you do not use the proper fuel cap, the
pressure in the fuel tank can damage the
fuel system or cause it to work improperly
in a collision.
*
[SV07025(ALL)05/95]
NOTE: If you replace your fuel cap with an
aftermarket fuel filler cap, the customer
warranty may be void for any damage
to the fuel tank and/or fuel system.
*
[SV07050(ALL)05/95]
RWARNING
If the fuel cap is venting vapor or if you
hear a hissing sound, wait until it stops
before completely removing the cap.
*
[SV07060(ALL)11/89]
A venting fuel tank is not an abnormal
condition. It may be caused by:
*
[SV07061(ALL)07/95]
q
Too volatile a fuel for the weather conditions.
The service stations sometimes sell winter
grade fuel in the summer.
*
[SV07062(ALL)11/89]
q
Pulling a heavy load on hot days, or at high
altitudes.
*
[SV07063(ALL)11/89]
q
Extended periods of idling with the engine
RPM increased above the normal idle range.
*
[SV07064(ALL)11/89]
q
Parking vehicle in full sunlight for extended
periods on extremely hot days.

Choosing the Right Fuel
*
[SV07600(ALL)06/95]
Use only UNLEADED FUEL in your vehicle.
Using leaded fuel is prohibited by federal law.
Your warranty may not apply if your vehicle is
damaged because you used the wrong fuel.
*
[SV07625(ALL)08/95]
Vehicle inspection programs may detect
misfueling. Under these circumstances, you may
be required by law to make costly repairs at
your own expense.
%*
[SV08750(ALL)08/95]
Octane recommendations
*
[SV08800(ALL)08/95]
Your engine is designed to use regular
unleaded 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 on a label
on the pumps.
*
[SV08900(ALL)06/95]
one inch art:0060001-C
Typical octane rating label
*
[SV09050(ALL)07/95]
In some parts of the country, ªregularº grade
fuels are sold with octane ratings of 86 or even
less, especially in high altitude areas. We
recommend that you do not use these fuels.
Always use a fuel with an octane rating of 87,
even if it is sold as a ªmidgradeº or ªpremium.º
[SV09200(ALL)08/95]
Do not be concerned if your vehicle sometimes
knocks lightly when you drive up a hill or when
you accelerate. However, if a fuel with the
recommended octane rating knocks heavily
under all driving conditions or knocks lightly
driving at cruising speed on level roads, see
your dealer or a qualified service technician.
Persistent, heavy knocking can damage the
engine.

Fuel quality
*
[SV09450(ALL)06/95]
If you are experiencing 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.
*
[SV09455(ALL)08/95]
Using a high-quality fuel makes your vehicle
more responsive and maintains its good fuel
economy and emissions by:
*
[SV09460(ALL)08/95]
q
minimizing deposits in fuel injectors,
combustion chambers and on intake valves.
*
[SV09465(ALL)08/95]
q
assuring quick starting and smooth warm-up.
*
[SV09470(ALL)08/95]
q
protecting the fuel system from vapor lock in
very hot weather, which causes the engine to
hesitate or stall and makes restarts difficult.
*
[SV09475(ALL)08/95]
q
protecting your fuel system from rusting.
*
[SV09480(ALL)08/95]
q
preventing the fuel lines from freezing.
*
[SV09485(ALL)08/95]
q
preventing the fuel system from ªgumming
upº when your vehicle is not used for long
periods of time.
*
[SV09500(ALL)06/95]
It should not be necessary to add any
aftermarket products to your fuel tank if you
continue to use a high-quality fuel.

[SV09600(ALL)04/95]
Gasolines for clean air
*
[SV09900(ALL)06/95]
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%).

[SV11000(ALL)01/95]
You may occasionally hear and/or feel a slight
thump occurring one or two seconds after a
gentle stop. This is normal and generally occurs
with the fuel tank 3/4 full. It is caused by the
wave action of the fuel within the tank.
%*
[SV11300(ALL)05/95]
Running Out of Fuel
*
[SV11400(ALL)05/95]
If your vehicle runs out of fuel, try to stop on
level ground away from traffic. Add at least two
gallons (8 liters) of fuel to start your vehicle
again. If your vehicle is not on level ground,
you may need as much as five gallons (20 liters)
of fuel to start it.
*
[SV11450(ALL)08/95]
NOTE: Avoid running out of fuel because this
situation may have an adverse effect on
modern powertrain components.
*
[SV11500(ALL)07/95]
You may need to crank the engine several times
before the fuel system starts to pump fuel from
the tank to the engine.

[SV11600(ALL)05/95]
Fuel Economy
*
[SV11700(ALL)07/95]
Fuel economy is an estimate of the efficiency of
your vehicle and can be calculated as Miles Per
Gallon (MPG) or Liters Per 100 Kilometers
(L/100K). Do not calculate the fuel economy
during your vehicle's break-in period. This
would not be an accurate estimate of how much
fuel your vehicle will normally use.
*
[SV11800(ALL)05/95]
To calculate fuel economy:
*
[SV11900(ALL)06/95]
1. Fill the tank completely and record the
initial odometer reading.
*
[SV12000(ALL)06/95]
2. Every time you buy fuel record the
amount (in gallons or liters) purchased.
[SV12200(ALL)08/95]
3. After at least three to five tankfuls, fill the
fuel tank and record the final odometer
reading.

economy:

[SV12250(ALL)08/95]
q
English: MPG = (total miles driven)v
(gallons used)
[SV12275(ALL)08/95]

Metric: L/100k = (100 x liters used)v(total
kilometers driven)

Comparisons With Environmental
Protection Agency (EPA) and Transport
Canada (TC) Fuel Economy Estimates
*
[SV12400(ALL)08/95]
EPA and TC fuel economy figures are obtained
from laboratory tests under simulated road
conditions and thus are estimates which may not
reflect the actual conditions you experience or
your personal style of driving. The EPA or TC
fuel economy estimate is not a guarantee that
you will achieve the fuel economy shown.
