•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. The use of leaded fuel is prohibited by law.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based additives.
Choosing the Right Fuel (Gasoline Vehicles)
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 the vehicle that is caused by the
use of fuel not recommended will not be covered under warranty.
Choosing the Right Fuel With a Flex Fuel Vehicle (If Equipped)
Use only UNLEADED gasoline or UNLEADED gasoline blended with
a maximum of 85% ethanol (E-85) in your Flex Fuel Vehicle (FFV).
If your vehicle is flex fuel capable, it will have a yellow bezel placed over
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)
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 a vehicle that is caused by use of fuel not
recommended will not be covered under warranty.
Octane Recommendations
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 under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized dealer to
prevent any engine damage.

Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
BRAKE FLUID CHECK
Fluid levels between the MIN and MAX lines are within the normal
operating range; there is no need to add fluid. If the fluid levels are
outside of the normal operating range, the performance of the system
could be compromised; seek service from your authorized dealer
immediately.
POWER STEERING FLUID CHECK
Check the power steering fluid. Refer toscheduled maintenance
information.
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
2. While the engine idles, turn the steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the reservoir. It should be between the MIN
and MAX lines. Do not add fluid if the level is in this range.
5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the range between the MIN and MAX lines. Be
sure to put the cap back on the reservoir. Refer to theCapacities and
Specificationschapter for the proper fluid type.
FUEL FILTER
Your vehicle is equipped with a lifetime fuel filter that is integrated with
the fuel tank. Regular maintenance or replacement is not needed.
WASHER FLUID CHECK
WARNING:If you operate your vehicle in temperatures below
40°F (5°C), use washer fluid with antifreeze protection. Failure
to use washer fluid with antifreeze protection in cold weather could
result in impaired windshield vision and increase the risk of injury or
accident.
Add fluid to fill the reservoir if the level is low. Only use a washer fluid
that meets Ford specifications. See the technical specifications chart in
theCapacities and Specificationschapter.
