DO NOT USE E-85 IN NON-FLEX
FUEL VEHICLES
Non-Flex Fuel Vehicles (FFV) are compatible with gaso-
line containing up to 15% ethanol (E-15). Use of gaso-
line with higher ethanol content may void the New
Vehicle Limited Warranty.
If a Non-FFV vehicle is inadvertently fueled with
E-85 fuel, the engine will have some or all of these
symptoms:
•
Operate in a lean mode.
•
OBD II Malfunction Indicator Light on.
•
Poor engine performance.
•
Poor cold start and cold drivability.
•
Increased risk for fuel system component corrosion.
CNG AND LP FUEL SYSTEM
MODIFICATIONS
Modifications that allow the engine to run on Com-
pressed Natural Gas (CNG) or Liquid Propane (LP) may
result in damage to the engine, emissions, and fuel
system components. Problems that result from running
CNG or LP are not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty.
MMT IN GASOLINE
Methylcyclopentadienyl Manganese Tricarbonyl (MMT)
is a manganese-containing metallic additive that is
blended into some gasolines to increase octane. Gaso-
line blended with MMT provides no performance advan-
tage beyond gasoline of the same octane number with-
out MMT. Gasoline blended with MMT reduces spark
plug life and reduces emissions system performance in
some vehicles. The manufacturer recommends that
gasoline without MMT be used in your vehicle. The
MMT content of gasoline may not be indicated on the
gasoline pump; therefore, you should ask your gasoline
retailer whether the gasoline contains MMT. MMT is
prohibited in Federal and California reformulated
gasoline.
FUEL SYSTEM CAUTIONS
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•
The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine per-
formance and damage the emissions control
system.
•
An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate ser-
vice. Contact an authorized dealer for service
assistance.
•
The use of fuel additives, which are now being sold
as octane enhancers, is not recommended. Most
of these products contain high concentrations of

CAUTION!
methanol. Fuel system damage or vehicle perfor-
mance problems resulting from the use of such
fuels or additives is not the responsibility of the
manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.
NOTE:
Intentional tampering with the emissions control system
can result in civil penalties being assessed against you.
