²If fuel is splashed in the eyes, remove contact lenses, flush with water
for 15 minutes and seek medical attention.
²Be 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. Consult a physician
immediately.
Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel is prohibited by law
and could damage your vehicle.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based compounds containing MMT.
Vehicles certified to California emission standards (indicated on the
underhood Vehicle Emissions Control Information label) are designed to
operate on California reformulated gasolines. If California reformulated
gasoline is not available when you refuel, your vehicle can be operated
on non-California fuels. However, even though your engine will perform
adequately on other gasolines, the performance of the emission control
devices and systems may be adversely affected.
Repair of damage caused by using a fuel that your vehicle was not
designed for may not be covered by your warranty.
Octane recommendations
Your vehicle is designed to use
``Regular'' unleaded with an (R+M)/2
octane rating of 87. We do not
recommend gasolines labeled as
``Regular'' in high altitude areas that
are sold with octane ratings of 86 or
even less.
Do not be concerned if your vehicle sometimes knocks lightly. However,
if it knocks heavily under most driving conditions on fuel with the
87

recommended octane, see your dealer or a qualified service technician to
prevent any engine damage.
Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems during a cold start, try a different brand of ``Regular'' gasoline.
``Premium'' gasoline is not recommended (particularly in the United
States) because it may cause these problems to become more
pronounced. If the problems persist, see your dealer or a qualified
service technician.
The American Automobile Manufacturers Association (AAMA) issued a
gasoline specification to provide information on high quality fuels that
optimize the performance of your vehicle. We recommend the use of
gasolines that meet the AAMA specification if they are available.
It should not be necessary to add any aftermarket products to your fuel
tank if you continue to use a high-quality fuel.
Cleaner air
Ford approves the use of gasolines to improve air quality, including
reformulated gasolines that contain oxygenates up to 10% ethanol or
15% MTBE.
Do not use gasolines containing methanol, which can damage critical fuel
system components. Damage resulting from the use of methanol may not
be covered by your warranty.
Calculating fuel economy
To accurately calculate your vehicle's fuel economy:
1. Fill the tank completely and record the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added (in liters
or gallons).
3. After at least three to five fuel tank fill-ups, fill the fuel tank and
record the current mileage reading.
4. Use one of the following equations to calculate fuel economy.
Liters used x 1004Total kilometers traveled
Total miles traveled4Total gallons used
Keep a record for at least one month. This will provide an accurate
estimate of the vehicle's fuel economy.

MERCON Vtapproved. Some fluids have been approved as meeting both
MERCONtand MERCONtV requirements and will be labeled as such.
Fluids labeled as meeting only MERCONtor only MERCONtV
