Note:
You may use either regular
unleaded gasoline or ethanol
fuel up to 85% (E-85).
See "Ethanol (E-85) Fuel"
later in this section for more
information.
The use of gasoline with an octane
rating lower than that recom-
mended may cause engine knock.
Continued use can cause engine
damage and void the warranty.
If you detect a heavy engine knock
even when using a gasoline of the
recommended octane rating,
have the engine checked. Short
periods of engine knock during hill
climbing and acceleration are
acceptable.

Ethanol (E-85) Fuel

NOTICE
Do not use methanol.
Your vehicle was not designed
for fuels that contain methanol.
Methanol can corrode metal
parts in your fuel system and
can also damage plastic and
rubber parts. Damage caused
by the use of fuels that contain
methanol would not be
covered by your warranty.
NOTICE
Some additives are not compat-
ible with E-85 fuel and may
harm your fuel system. Damage
caused by the use of additives
may not be covered by your
new vehicle warranty. Do not
use additives with E-85 fuel.
Section 4
You may use either regular
unleaded gasoline or ethanol fuel
up to 85% (E-85).
E-85 fuel is a blend of
approximately 85% ethanol
and 15% gasoline. E-85 is a high-
octane, renewable fuel made
primarily from corn.
At a minimum, ethanol fuel
should meet either ASTM D 5798
or EN 15293 specifications.
Fuel labeled E-85 that meets the
required specifications will contain
70% to 85% ethanol.
Note:
Filling the fuel tank with fuel
mixtures that do not meet
required ethanol fuel specifica-
tions can affect driveability and
could cause the malfunction
indicator light to come on.
See "Malfunction Indicator
Light" under "Indicator and
Warning Lights" in Section 1 for
more information.
