•Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
•Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
•Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
•
Be particularly careful if you are taking Antabuse or other forms of
disulfiram for the treatment of alcoholism. Breathing gasoline vapors, or
skin contact could cause an adverse reaction. In sensitive individuals,
serious personal injury or sickness may result. If fuel is splashed on the
skin, promptly wash skin thoroughly with soap and water. Consult a
physician immediately if you experience an adverse reaction.
FUEL QUALITY
Note:Use of any fuel other than those recommended may cause
powertrain damage and a loss of vehicle performance; repairs may not be
covered under warranty.
Choosing the Right Fuel (Gasoline Engines)
Use only UNLEADED gasoline or UNLEADED gasoline blended with a
maximum of 15% ethanol in your gasoline vehicle. If your vehicle is a
Flex Fuel Vehicle (FFV), it will have a yellow bezel placed over the fuel
fill inlet.
Do not use:
•Fuels containing more than 15% ethanol or E-85 fuel.
•Fuels containing methanol.
•Fuels containing metallic based additives, including manganese-based
compounds.
•Fuels containing the octane booster additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
•Leaded-fuel (The use of leaded fuel is prohibited by law).
Note:Use of any fuel other than recommended fuel can cause
powertrain damage, impair the emission control system or cause loss of
vehicle performance. Any damage to vehicle that is caused by use of fuel
not recommended will not be covered under warranty.

the fuel fill inlet
Do not use:
•fuels containing more than 85% ethanol or E-100 fuel
•fuels containing methanol
•fuels containing metallic based additives, including manganese-based
compounds
•fuels containing the octane booster additive, methylcyclopentadienyl
manganese tricarbonyl (MMT)
•leaded-fuel (The use of leaded fuel is prohibited by law)
Note:Use of any fuel other than recommended fuel can cause

Octane recommendations
3.5L V6 engine:
Regular unleaded gasoline with a pump (R+M)/2 octane rating of 87 is
recommended. Some stations offer fuels posted as Regular with an
octane rating below 87, particularly in high altitude areas. Fuels with
octane levels below 87 are not recommended.
2.0L/3.5L EcoBoost® engines:
Regular unleaded gasoline with a pump (R+M)/2 octane rating of 87 is
recommended. Some stations offer fuels posted as “Regular” with an
octane rating below 87, particularly in high altitude areas. Fuels with
octane levels below 87 are not recommended. Premium fuel will provide
improved performance and is recommended for severe duty usage such
as trailer tow.
Do not be concerned if your engine
sometimes knocks lightly. However, if
it knocks heavily while you are using
fuel with the recommended octane
rating, see your authorized dealer to
prevent any engine damage.
