WARNING!
You can be badly injured working on or around a motor vehicle. Do only service work for which you have the knowledge and the right equipment. If you have
any doubt about your ability to perform a service job, take your vehicle to a competent mechanic.
Failure to properly inspect and maintain your vehicle could result in a component malfunction and effect vehicle handling and performance. This could cause
an accident.

TECHNICAL SPECIFICATIONS379
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with
oxygenates such as ethanol.
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 Limited
Warranty.
DO NOT USE E-85 IN NON-FLEX FUEL
V
EHICLES
Non-Flex Fuel Vehicles (FFV) are compatible with
gasoline containing up to 15% ethanol (E-15). Use
of gasoline 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
M
ODIFICATIONS
Modifications that allow the engine to run on
Compressed 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 manufacturer and may void or
not be covered under the New Vehicle Limited
Warranty.
METHYLCYCLOPENTADIENYL
M
ANGANESE TRICARBONYL (MMT) IN
G
ASOLINE
MMT is a manganese-containing metallic additive
that is blended into some gasoline 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 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.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 drivability problems, damage critical fuel
system components, 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).
