to check the bulb. If it comes on after the engine is
started, one of the engine's emission control systems
may be malfunctioning. The light may illuminate
without a driveability concern being noted. The
vehicle will usually be drivable and will not require
towing.
What you should do if the Service Engine Soon
light illuminates
Light turns on solid:
This means that the OBD II system has detected a
malfunction.
Temporary malfunctions may cause yourService
Engine Soonlight to illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may
misfire or run poorly.)
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed
and securely tightened.
These temporary malfunctions can be corrected by
filling the fuel tank with high quality fuel of the
recommended octane and/or properly installing and
securely tightening the gas cap. After three driving
cycles without these or any other temporary
malfunctions present, theService Engine Soonlight
should turn off. (A driving cycle consists of a cold
engine startup followed by mixed city/highway
driving.) No additional vehicle service is required.
If theService Engine Soonlight remains on, have
your vehicle serviced at the first available
opportunity.
Light is blinking:
Engine misfire is occurring which could damage your
catalytic converter. You should drive in a moderate
fashion (avoid heavy acceleration and deceleration)
and have your vehicle serviced at the first available
opportunity.
Instrumentation

The fuel system may be under pressure. If
the fuel filler cap is venting vapor or if you
hear a hissing sound, wait until it stops before
completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.
If you do not use the proper fuel filler cap,
excessive pressure or vacuum in the fuel
tank may damage the fuel system or cause the fuel
system to work improperly in a collision, which
may result in possible personal injury.
Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel
is prohibited by law and could damage your vehicle.
Do not use fuel containing methanol. It can damage
critical fuel system components.
Your vehicle was not designed to use fuel or fuel
additives with metallic compounds, including
manganese-based compounds containing MMT.
Repairs to correct the effects of using a fuel for
which your vehicle was not designed may not be
covered by your warranty.
Octane recommendations
Your vehicle is
designed to use
ªRegularº unleaded
gasoline with an
(R+M)/2 octane rating of 87. We do not recommend
the use of gasolines labeled as ªRegularº that are
sold with octane ratings of 86 or lower in high
altitude areas.
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 dealer or
87(R+M)/2 METHOD
Maintenance and care
169

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 ªRegularº unleaded gasoline.
ªPremiumº unleaded 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.
It should not be necessary to add any aftermarket
products to your fuel tank if you continue to use
high quality fuel of the recommended octane rating.
Aftermarket products could cause damage to the
fuel system. Repairs to correct the effects of using
an aftermarket product in your fuel may not be
covered by your warranty.
Many of the world's automakers issued the
World-wide Fuel Charter that recommends gasoline
specifications to provide improved performance and
emission control system protection for your vehicle.
Gasolines that meet the World-wide Fuel Charter
should be used when available. Ask your fuel
supplier about gasolines that meet the World-wide
Fuel Charter.
Cleaner air
Ford approves the use of reformulated
ªcleaner-burningº gasolines to improve air quality.
These gasolines may contain oxygenates up to 10%
ethanol or 15% MTBE.
Running out of fuel
Avoid running out of fuel because this situation may
have an adverse affect on powertrain components.
Maintenance and care
170

The advertised capacity is the amount of the
indicated capacity and the empty reserve combined.
Indicated capacity is the difference in the amount of
fuel in a full tank and a tank when the fuel gauge
indicates empty. Empty reserve is the small amount
of usable fuel remaining in the fuel tank after the
fuel gauge indicates empty.
The amount of empty reserve varies and should
not be relied upon to increase driving range.
When refueling your vehicle after the fuel
gauge indicates empty, you might not be able to
refuel the full amount of the advertised
capacity of the fuel tank due to the empty
reserve still present in the tank.
For consistent results when filling the fuel tank:
²Use the same filling rate setting (low Ð medium
Ð high) each time the tank is filled.
²Allow three automatic click-offs when filling.
²Always use fuel with the recommended octane
rating.
²Use a known quality gasoline, preferably a
national brand.
²Use the same side of the same pump and have
the vehicle facing the same direction each time
you fill up.
²Have the vehicle loading and distribution the
same every time.
Your results will be most accurate if your filling
method is consistent.
Calculating fuel economy
1. Fill the fuel tank completely and record the initial
odometer reading (in kilometers or miles).
2. Each time you fill the tank, record the amount of
fuel added (in liters or gallons).
3. After at least three to five tank fill-ups, fill the
fuel tank and record the current odometer reading.

1Add 118 ml (4 oz.) of Additive Friction Modifier C8AZ-19B546-A or
equivalent meeting Ford specification EST-M2C118-A for complete
refill of Traction-Lok axles.
Ford design rear axles contain a synthetic lubricant that does not
require changing unless the axle has been submerged in water.
2Ensure the correct automatic transmission fluid is used.
Transmission fluid requirements are indicated on the dipstick or on
the dipstick handle. MERCONtand MERCONtV are not
interchangeable. DO NOT mix MERCONtand MERCONtV. Refer to
your Scheduled Maintenance Guide to determine the correct service
interval.
