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.
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.

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. 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 mon-
oxide 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
time the vehicle is raised. Have any abnormal condi-
tions repaired promptly. Until repaired, drive with
all side windows fully open.

FLEXIBLE FUEL (2.4L ENGINE ONLY) —
IF EQUIPPED
E-85 General Information
The information in this section is unique for Flexible Fuel
vehicles only. These vehicles can be identified by a unique
fuel filler door label that statesEthanol (E-85) or Unleaded
Gasoline Only and a yellow fuel cap. Please refer to the
other sections of this manual for information on features
that are common between Flexible Fuel and non-Flexible
Fuel powered vehicles.
CAUTION!
Only vehicles with the E-85 fuel filler door label or a
yellow gas cap can operate on E-85.
Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% ethanol and 15%
unleaded gasoline.
WARNING!
Ethanol vapors are extremely flammable and could
cause serious personal injury. Never have any smoking
materials lit or products that can cause spark in or near
the vehicle when removing the fuel filler tube cap (gas
cap) or filling the tank. Do not use E-85 as a cleaning
agent and never use it near an open flame.
Fuel Requirements
If your vehicle is E-85 compatible, it will operate on
unleaded gasoline with any octane rating, or solely E-85
fuel, or any mixture of these fuels.
For best results, avoid fueling patterns alternating be-
tween E-85 and unleaded gasoline.
When switching fuel types:
• Add 5 gallons (19 liters) or more when refueling.
• Drive the vehicle immediately after refueling for at least
5 miles (8 km).
Observing these precautions will avoid possible hard start-
ing and/or driveability problems during warm up.
518 TECHNICAL SPECIFICATIONS

NOTE:
•Use seasonally adjusted E-85 fuel (ASTM D5798). With
non-seasonally adjusted E-85 fuel, hard starting and
rough idle following start up may be experienced even if
the above recommendations are followed, especially
when the ambient temperature is below 32°F (0°C).
• Some additives used in regular gasoline are not fully
compatible with E-85 and may form deposits in your
engine. To eliminate driveability issues that may be
caused by these deposits, a supplemental gasoline addi-
tive, such as MOPAR Injector Cleanup or Techron may
be used.Selection Of Engine Oil For Flexible Fuel Vehicles
(E-85) And Gasoline Vehicles
FFV vehicles operated on E-85 require specially formulated
engine oils. These special requirements are included in
MOPAR engine oils, and in equivalent oils meeting FCA
US Material Standard MS-6395. It is recommended that
engine oils that are API Certified and meet the require-
ments of Material Standard MS-6395 be used. MS-6395
contains additional requirements, developed during exten-
sive fleet testing, to provide additional protection to FCA
US LLC engines.
Starting
The characteristics of E-85 fuel make it unsuitable for use
when ambient temperatures fall below 0°F (-18°C). In the
range of 0°F (-18°C) to 32°F (0°C), an increase in the time it
takes for your engine to start may be experienced, and a
deterioration in driveability (sags and/or hesitations) until
the engine is fully warmed up. These issues may be
improved with the use of seasonally adjusted E-85 fuel.
NOTE: Use of the engine block heater (if equipped) may
improve engine start time when using E-85 fuel when the
ambient temperature is less than 32°F (0°C).9
TECHNICAL SPECIFICATIONS 519

Cruising Range
Because E-85 fuel contains less energy per gallon/liter than
gasoline, an increase in fuel consumption will be experi-
enced. The miles per gallon (mpg)/kilometers per liter and
the driving range will decrease by approximately 30%,
compared to gasoline operation.
Replacement Parts
All fuel and engine components in your Flexible Fuel
Vehicle (FFV) are designed to be compatible with ethanol.
Ethanol compatible service components are required.
CAUTION!
Replacing fuel system components with non-ethanol
compatible components can damage your vehicle.
Maintenance
CAUTION!
Do not use ethanol mixture greater than 85% in your
vehicle. It will cause difficulty in cold starting and may
affect drivability.

CAUTION!
•Mixing of engine coolant (antifreeze) other than speci-
fied Organic Additive Technology (OAT) engine cool-
ant (antifreeze), may result in engine damage and may
decrease corrosion protection. Organic Additive Tech-
nology (OAT) engine coolant is different and should
not be mixed with Hybrid Organic Additive Technol-
ogy (HOAT) engine coolant (antifreeze) or any “glob-
ally compatible” coolant (antifreeze). If a non-OAT
engine coolant (antifreeze) is introduced into the cool-
ing system in an emergency, the cooling system will
need to be drained, flushed, and refilled with fresh
OAT coolant (conforming to MS.90032), by an autho-
rized dealer as soon as possible.
• Do not use water alone or alcohol-based engine
coolant (antifreeze) products. Do not use additional
rust inhibitors or antirust products, as they may not
be compatible with the radiator engine coolant and
may plug the radiator.
• This vehicle has not been designed for use with
propylene glycol-based engine coolant (antifreeze).
Use of propylene glycol-based engine coolant (anti-
freeze) is not recommended.
