FLEXIBLE FUEL (3.6L ENGINE
ONLY) — IF EQUIPPED
E-85 General Information
The information in this section is for Flexible
Fuel vehicles only. These vehicles can be iden-
tified by a unique fuel filler door label that states
Ethanol (E-85) or Unleaded Gasoline Only.
This section only covers those subjects that are
unique to these vehicles. Please refer to the
other sections of this manual for information on
features that are common between Flexible
Fuel and gasoline-only powered vehicles.
Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline.
WARNING!
Ethanol vapors are extremely flammable and
could cause serious personal injury. Never
have any smoking materials lit 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
Your vehicle will operate on both unleaded
gasoline with a minimum Research Octane
Number (RON) of 91, or E-85 fuel, or any
mixture of these two. For best results, a refuel-
ing pattern that alternates between E-85 and
unleaded gasoline should be avoided.
When you do switch fuel types it is recom-
mended that:
•
You do not add less than 5 gallons (19 Liters)
when refueling.
•
You operate the vehicle immediately after
refueling for a period of at least 5 minutes.
Observing these precautions will avoid possible
hard starting and/or significant deterioration in
driveability during warm up.
NOTE:
•
When the ambient temperature is above
90° F (32° C), you may experience hard
starting and rough idle following start up
even if the above recommendations are
followed.
