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 (3.6L ENGINE ONLY)
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 states Ethanol (E-85) or Unleaded
Gasoline Only and/or 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

WARNING!(Continued)
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. 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 requirements of
Material Standard MS-6395 be used. MS-6395 contains
additional requirements, developed during extensive fleet
testing, to provide additional protection to FCA US LLC
engines.
