designed for automotive use or are not
properly installed. For example, when
operated, such systems may cause the
engine to stumble or stall. In addition,
such systems may themselves be
damaged or their operation affected by
operating your vehicle. (Citizens band
[CB] transceivers, garage door openers,
and other transmitters whose power
output is 5 watts or less will not
ordinarily affect your vehicle's
operation.)

Cleaning the Engine
*
[SV06000( 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.
*
[SV06020( ALL)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.
*
[SV06040( ALL)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.
*
[SV06060( ALL)04/95]
q
The alternator, distributor and air intake must
be covered. Covering these components will
help prevent water damage.
*
[SV06080( ALL)04/95]
q
Never wash or rinse the engine while it is
running. Water getting into the engine may
cause internal damage.

Filling the Fuel Tank

[SV06550( ALL)05/95]
1. After opening the fuel filler door, remove
the cap carefully and slowly by turning it
counterclockwise 1/2 to 3/4 turn.
[SV06650( ALL)05/95]
RWARNING
The fuel system may be under pressure. If
the fuel cap is venting vapor or if you
hear a hissing sound while disengaging
the fuel cap, wait until it stops before
completely removing the cap. Otherwise,
fuel may spray out and injure you or
others.

236 [SV08750( ALL)05/95]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%).
