Indiscriminate use of fuel system cleaning agents
should be avoided. Many of these materials intended
for gum and varnish removal may contain active sol-
vents or similar ingredients. These can harm fuel sys-
tem gasket and diaphragm materials.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as ethanol.
CAUTION!
DO NOT use E-85, gasoline containing methanol, or
gasoline containing more than 15% ethanol (E-15).
Use of these blends may result in starting and driv-
ability problems, damage critical fuel system compo-
nents, cause emissions to exceed the applicable
standard, and/or cause the Malfunction Indicator
Light to illuminate. Please observe pump labels as
they should clearly communicate if a fuel contains
greater than 15% ethanol (E-15).
Problems that result from using gasoline containing
more than 15% ethanol (E-15) or gasoline containing
methanol are not the responsibility of the manufacturer
and may void or not be covered under New Vehicle Lim-
ited Warranty.
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.
METHYLCYCLOPENTADIENYL
MANGANESE TRICARBONYL (MMT)
IN GASOLINE
MMT is a manganese-containing metallic additive that
is blended into some gasolines to increase octane.
Gasoline blended with MMT provides no performance
advantage beyond gasoline of the same octane number
without MMT. Gasoline blended with MMT reduces
spark plug life and reduces emissions system perfor-
mance in some vehicles. The manufacturer recom-
mends that gasoline without MMT be used in your
vehicle. The MMT content of gasoline may not be indi-
cated on the gasoline pump; therefore, you should ask
the gasoline retailer whether the gasoline contains
MMT. MMT is prohibited in Federal and California refor-
mulated 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
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.
