Cleaning the Engine
*
[SV05920(BEF )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.
*
[SV05940(BEF )05/95]
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.
*
[SV05960(BEF )04/95]
q
In order to avoid possible cracking of the
engine block or fuel injection pump, do not
spray a hot engine or injection pump with
cold water.
*
[SV05980(BEF )04/95]
q
The alternator, distributor and air intake must
be covered. Covering these components will
help prevent water damage.
*
[SV06000(BEF )04/95]
q
Never wash or rinse the engine while it is
running. Water getting into the engine may
cause internal damage.

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(BEF )11/89]
A venting fuel tank is not an abnormal
condition. It may be caused by:
*
[SV07061(BEF )03/90]
q
Too volatile a fuel for the weather conditions.
The service stations sometimes sell winter
grade fuel in the summer.
*
[SV07062(BEF )11/89]
q
Pulling a heavy load on hot days, or at high
altitudes.
*
[SV07063(BEF )11/89]
q
Extended periods of idling with the engine
RPM increased above the normal idle range.
*
[SV07064(BEF )11/89]
q
Parking vehicle in full sunlight for extended
periods on extremely hot days.
*
[SV07500( ALL)05/95]
Choosing the Right Fuel
*
[SV07600( ALL)05/95]
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.
*
[SV07700( ALL)05/95]
Vehicle inspection programs may detect
misfueling. Under these circumstances, you may
be required by law to make costly repairs at
your own expense.

Octane recommendations
*
[SV08725( ALL)04/95]
Your vehicle 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)05/95]
one inch art:0060001-C
Typical octane rating label
*
[SV09050( ALL)05/95]
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)05/95]
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.
*
[SV09435( ALL)05/95]
Fuel quality
*
[SV09450( ALL)05/95]
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.

[SV09452( ALL)05/95]
Using a high-quality fuel makes your vehicle
more responsive and maintains its good fuel
economy and emissions by:
*
[SV09455( ALL)05/95]
q
protecting your fuel system from rusting.
*
[SV09460( ALL)05/95]
q
preventing the fuel lines from freezing.
*
[SV09465( ALL)05/95]
q
improving vehicle starting and warm-up.
*
[SV09470( ALL)05/95]
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)05/95]
q
minimizing deposits in fuel injectors,
combustion chambers, and on intake valves.
*
[SV09480( ALL)05/95]
q
preventing your fuel system from ªgumming
upº when your vehicle is not used for long
periods of time.

[SV09485( ALL)05/95]
q
preventing your engine from knocking and
pinging.
*
[SV09500( ALL)05/95]
It should not be necessary to add any
aftermarket products to your fuel tank if you
continue to use a high-quality fuel.
*
[SV09875( ALL)04/95]
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%).
[SV09950( ALL)04/95]
Reformulated gasoline is also required in certain
areas of the U.S. These fuels are designed to
further reduce the emissions from your vehicle.

Fuel Economy
*
[SV11700( ALL)05/95]
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).
*
[SV11750( ALL)05/95]
Do not calculate 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)05/95]
1. Fill the tank completely and record the inital
odometer reading.
*
[SV12000( ALL)05/95]
2. Every time you buy fuel record the
amount (in gallons or liters) purchased.
*
[SV12200( ALL)05/95]
3. After at least three to five tankfuls, fill the
fuel tank and record the final odometer
reading.
*
[SV12225( ALL)05/95]
4. Use these equations to calculate your fuel
economy.
*
[SV12250( ALL)05/95]
q
English: MPG = (total miles)/(gallons used).
*
[SV12275( ALL)05/95]
q
Metric: L/100K = (liters used) x 100/(total
kilometers)

Comparisons With EPA Fuel Economy
Estimates
*
[SV12400(BEF )05/95]
EPA fuel economy figures are obtained from
laboratory tests under simulated road conditions
and may not reflect the actual conditions you
experience or your style of driving. The EPA
fuel economy estimate is not a guarantee that
you will achieve the fuel economy shown.

Improving Fuel Economy
*
[SV12600( ALL)05/95]
Fuel economy is affected by a number of
variables which can reduce efficiency. You can
improve fuel economy by understanding these
variables and minimizing their effect.
*
[SV12700( ALL)05/95]
The following decrease fuel economy:
*
[SV12800( ALL)05/95]

Checking and Adding Engine Oil
*
[SV13800( ALL)03/95]
Since the proper amount of engine oil is
important for safe engine operation, check the oil
using the dipstick each time you put fuel in
your vehicle. Remember the engine must be off,
the oil must be warm and the vehicle must be
parked on level ground.
*
[SV13900( ALL)03/95]
Checking the engine oil level:
*
[SV14000( ALL)02/95]
1. Turn the engine off after it has warmed up
and allow a few minutes for the engine oil
to drain back into the oil pan.
*
[SV14050(B F )03/95]
2. Set the parking brake, making sure that the
gearshift is securely latched in P (Park)
(automatic transmission) or 1 (First) (manual
transmission).
*
[SV14100( ALL)02/95]
3. Open the hood. Protect yourself from engine
heat.
*
[SV14200( ALL)03/95]
4. Locate the engine oil dipstick (highlighted in
yellow) and carefully pull it out of the
engine.
*
[SV14300( ALL)01/95]
5. Wipe the dipstick clean and put it back into
position, making sure it is fully seated.

6. Carefully, pull the dipstick out again. If the
oil level is below the ªADD 1 QT.º line, add
engine oil as necessary. If the oil level is
beyond the letter ªFº in FULL, engine
damage or high oil consumption may occur
and some oil must be removed from the
engine.
*
[SV14600( ALL)01/95]
7. Put the dipstick back in and make sure it is
fully seated.
*
[SV14800( ALL)01/95]
It may be necessary to add some oil between oil
changes. Make sure you use a CERTIFIED
engine oil of the preferred viscosity. Your
vehicle's warranty coverage may not apply if
engine damage is caused by the use of improper
engine oil.
*
[SV15000( ALL)03/95]
Add engine oil through the oil filler cap
highlighted in yellow. To add oil, remove the
filler cap and use a funnel to pour oil into the
opening. Be careful not to overfill the engine.
Recheck the oil level after you finish adding oil.
*
[SV16500( ALL)04/95]
Change the engine oil and oil filterper the
following, whichever occurs first.
