REQUIREMENTS
using high-quality unleaded "Regular"
gasoline having a posted octane
number of 91 as specified by the
(R+M)/2 method. For optimum
performance and fuel economy the use
of "Premium" 91 octane gasoline or
higher is recommended.
While operating on gasoline with the
required octane number, hearing a light
knocking sound from the engine is not
a cause for concern. However, if the
engine is heard making a heavy
knocking sound, see your dealer
immediately. Use of gasoline with a
lower than recommended octane
number can cause engine failure and
may void or not be covered by the New
Vehicle Limited Warranty.
Poor quality gasoline can cause
problems such as hard starting, stalling,
and hesitations. If you experience these
symptoms, try another brand of
gasoline before considering service for
the vehicle.

Some fuel suppliers blend unleaded
gasoline with oxygenates such as
ethanol.
DO NOT use 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).
Caution!
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.

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.
