REFUELING THE
VEHICLE

Refueling The Vehicle

Stop the engine before refueling.

Fuel Requirements

Vehicles with catalytic converters or
oxygen sensors must use ONLY
UNLEADED FUEL, which will reduce
exhaust emissions and keep spark plug
fouling to a minimum.
Fuel: Premium
unleaded fuel.
Octane Rating
(Anti-knock index): 91
(R + M)/2 method or
above (96 RON or
above) (U.S. federal
law requires that octane ratings be
posted on gasoline station pumps).
Regular unleaded fuel with an octane
rating from 87 to 90 (91 to 95 RON) can
be used, but this will reduce
performance slightly, such as reduced
engine output, and engine knocking.
Fuel with a rating lower than 87 octane
(91 RON) will negatively affect the
emission control system performance
and could also cause engine knocking
and serious engine damage.
While operating on gasoline with an
octane number of 87, 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 authorized dealer
immediately. Use of gasoline with an
octane number lower than 87 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.
Gasoline blended with oxygenates such
as alcohol or ether compounds are
generally referred to as oxygenated fuels.
The common gasoline blend that can
be used with your vehicle is ethanol
blended at no more than 15%. Gasoline
containing alcohol, such as ethanol or
methanol, may be marketed under the
name "Gasohol".
Vehicle damage and problems resulting
from the use of the following may not
be covered by the New Vehicle Limited
Warranty:
Alcohol containing more than 15%
ethanol.
Gasoline or alcohol containing
methanol.
Leaded fuel or leaded alcohol.

Reformulated Gasoline

Many areas of the country require the
use of cleaner burning gasoline referred
to as "Reformulated Gasoline".
Reformulated gasoline contains
oxygenates and are specifically blended
to reduce vehicle emissions and
improve air quality.
The use of reformulated gasoline is
recommended. Properly blended
reformulated gasoline will provide
improved performance and durability of
engine and fuel system components.
Gasoline/Oxygenate
Blends
Some fuel suppliers blend unleaded
gasoline with oxygenates 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 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).
