WARNING!
A fire may result if gasoline is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place gas containers on the ground
while filling.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that
the fuel filler cap is loose, improperly installed,
or damaged, a loose gascap indicator will dis-
play in the instrument cluster telltale display
area. Refer to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
Tighten the fuel filler cap properly and push the RIGHT
button to turn off the message. If the problem continues,
the message will appear the next time the vehicle is started.
Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines that have these additives will help improve fuel economy,
reduce emissions, and maintain vehicle performance.
Designated TOP TIER Detergent Gaso-
line contains a higher level of detergents
to further aide in minimizing engine
and fuel system deposits. When avail-
able, the usage of Top Tier Detergent
gasoline is recommended. Visit
www.toptiergas.com for a list of TOP
TIER Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning agents should be
avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and dia-
phragm materials.
VEHICLE LOADING
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo.
The label also specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.
288 STARTING AND OPERATING
FUEL REQUIREMENTS
6.4L Engine
Do not use E-85 flex fuel or ethanol blends greater than
15% in this engine.This engines is designed to meet all
emissions regulations and provide satis-
factory fuel economy and performance
when using high quality unleaded gaso-
line having a posted octane number
range of 87 to 89 as specified by the
(R+M)/2 method. The use of 89 octane
“Plus” gasoline is recommended for optimum performance
and fuel economy.
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 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 consider-
ing service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner burning
gasoline referred to as “Reformulated Gasoline”. Reformu-
lated gasoline contains oxygenates and are specifically
blended to reduce vehicle emissions and improve air quality.
The use of reformulated gasoline is recommended. Prop-
erly blended reformulated gasoline will provide improved
performance and durability of engine and fuel system
components.
Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines that
have these additives will help improve fuel economy,
reduce emissions, and maintain vehicle performance.
428 TECHNICAL SPECIFICATIONS
CNG And LP Fuel System Modifications
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 compo-
nents. 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.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (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. Gaso-
line 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.
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 perfor-
mance 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 service.
Contact your 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 metha-
nol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or
additives is not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty.
