FUEL REQUIREMENTS
6.4L Engine
This engine is designed to meet all emis-
sions regulations and provide improved
fuel economy and performance when us-
ing high-quality premium unleaded gaso-
line with an octane rating of 91 or higher.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before consid-
ering service for the vehicle. Engine damage resulting
from operating from operating with heavy spark knock
may void or not be covered by the new vehicle warranty.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline”.
Reformulated gasoline contain oxygenates and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The use of reformulated gasoline is recommended. Prop-
erly blended reformulated gasoline will provide im-
proved performance and durability of engine and fuel
system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as ethanol.

STARTING AND OPERATING 471
Page 474 of 636

CAUTION!
DO NOT use gasoline containing methanol or gaso-
line 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).
Problems that result from using gasoline containing
Methanol or gasoline containing more than 10% ethanol
are not the responsibility of the manufacturer and may
void or not be covered under New Vehicle Limited
Warranty.
E-85 Usage In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gaso-
line containing up to 10% ethanol (E10). Gasoline with
higher ethanol content may void the New Vehicle Lim-
ited 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.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT)
is a manganese-containing metallic additive that is

Page 475 of 636

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.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and they would result in additional cost.
Therefore, you should not have to add anything to the
fuel.
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 sys-
tem.
•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 your authorized dealer for service
assistance.

CAUTION!(Continued)
•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.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as
a garage, and never sit in a parked vehicle with the
engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.
•Guard against carbon monoxide with proper main-
tenance. Have the exhaust system inspected every

WARNING!(Continued)
time the vehicle is raised. Have any abnormal
conditions repaired promptly. Until repaired, drive
with all side windows fully open.
ADDING FUEL
1. Press the fuel filler door release switch (located under
the headlamp switch).
2. Open the fuel filler door.

NOTE:In certain cold conditions, ice may prevent the
fuel door from opening. If this occurs, lightly push on the
fuel door to break the ice buildup and re-release the fuel
door using the inside release button. Do not pry on the
door.3. There is no fuel filler cap. A flapper door inside the
pipe seals the system.
4. Insert the fuel nozzle fully into the filler pipe, the
nozzle opens and holds the flapper door while refuel-
ing.
5. Fill the vehicle with fuel, when the fuel nozzle “clicks”
or shuts off the fuel tank is full.
6. Wait 5 seconds before removing the fuel nozzle to
allow fuel to drain from nozzle.
7. Remove the fuel nozzle and close the fuel door.
Emergency Gas Can Refueling
•Most gas cans will not open the flapper door.
•A funnel is provided to open the flapper door to allow
emergency refueling with a gas can.
•Retrieve funnel from the spare tire storage area.
Fuel Filler Door

•Insert funnel into same filler pipe opening as the fuel
nozzle.
•
Ensure funnel is inserted fully to hold flapper door open.
•Pour fuel into funnel opening.
•Remove funnel from filler pipe, clean off prior to
putting back in the spare tire storage area.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
•Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and may cause the “Malfunction Indicator
Light” to turn on.
•A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the
ground while filling.

Emergency Fuel Filler Door Release
If you are unable to open the fuel filler door, use the fuel
filler door emergency release.
1. Open the liftgate.
2. Push the inboard edge of the left storage bin to the
center, this will pop up the outboard edge.
3. Grab popped up outboard edge with other hand to
disengage snaps.
4. Remove the storage bin.
5. Pull the release cable to open the fuel door, push the
release cable back to the home position to re-seat the
fuel door latch to the closed position.NOTE:If the fuel door does not latch after the manual
release cable has been activated, the actuator latch should
be manually returned to the closed position.
