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.
FFV engine (if equipped)
Your FFV will operate well on ordinary ªRegularº unleaded gasoline, but
only the highest quality fuel ethanol will provide the same level of
protection and performance. To identify if your vehicle is an FFV, check
your VIN or the label on the inside of your fuel filler door. When
checking the VIN, look for the engine type identifier (8th character). If
your vehicle is an FFV, then the character will be labeled as a ª2º.
If you operate your vehicle 50% or more of the time on ethanol, you
should follow a different maintenance schedule. See theScheduled
Maintenance Guidefor more information.
If you are experiencing a rough or rolling idle after start-up with the
outside temperature above 27É C (80É F), the idle should improve within
10 to 30 seconds. If the problems persist below this temperature, see
your dealer or a qualified service technician.
Cleaner air
Ford endorses the use of reformulated ªcleaner-burningº gasolines to
improve air quality.
Running out of fuel
Avoid running out of fuel because this situation may have an adverse
affect on powertrain components.
If you have run out of fuel:
²You may need to cycle the ignition from OFF to ON several times after
refueling, to allow the fuel system to pump the fuel from the tank to
the engine.
²The
indicator may come on. For more information on the
Service engine soonindicator, refer to theInstrument Cluster
chapter.
Fuel Filter
For fuel filter replacement, see your dealer or a qualified service
technician. Refer to the scheduled maintenance guide for the appropriate
intervals for changing the fuel filter.
Replace the fuel filter with an authorized Motorcraft part. The
customer warranty may be void for any damage to the fuel system
if an authorized Motorcraft fuel filter is not used.

ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fill-ups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1,600 km (1,000 miles)
of driving (engine break-in period). You will get a more accurate
measurement after 3,000 km±5,000 km (2,000 miles-3,000 miles).
Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theRefill capacities
section of this chapter.
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 fuel remaining in the fuel
tank after the fuel gauge indicates empty.
The amount of usable fuel in the 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:
²Turn the engine/ignition switch to the off position prior to refueling,
an error in the reading will result if the engine is left running.
²Use the same filling rate setting (low Ð medium Ð high) each time
the tank is filled.
²Allow no more than 2 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).
Maintenance and Specifications

It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of L/100 km (MPG)
expected on the vehicle under optimum conditions. Your fuel economy
may vary depending upon the method of operation and conditions.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
²Use only unleaded fuel (or E85, if equipped with the 3.0L FFV V6
engine).
²Avoid running out of fuel.
²Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
²Have the items listed in yourScheduled Maintenance Guide
performed according to the specified schedule.
The scheduled maintenance items listed in theScheduled Maintenance
Guideare essential to the life and performance of your vehicle and to its
emissions system.
If other than Ford, Motorcraft or Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and durability.
Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.
Illumination of the
indicator, charging system warning light or the
temperature warning light, fluid leaks, strange odors, smoke or loss of
engine power, could indicate that the emission control system is not
working properly.
Exhaust leaks may result in entry of harmful and potentially
lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,

1Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the dipstick or on the dipstick
handle. Check the container to verify the fluid being added is of the
correct type. Refer to yourScheduled Maintenance Guideto determine
the correct service interval.
Some transmission fluids may be labeled as dual usage, such as
MERCONtand MERCONtV. These dual usage fluids are not to be used
in an automatic transmission that requires use of the MERCONttype
fluid. However, these dual usage fluids may be used in transmissions that
require the MERCONtV type fluid.
MERCONtand MERCONtV type fluids are not interchangeable.
DO NOT mix MERCONtand MERCONtV. Use of a transmission
fluid that indicates dual usage (MERCONtand MERCONtV) in
an automatic transmission application requiring MERCONtmay
cause transmission damage. Use of any fluid other than the
recommended fluid may cause transmission damage.
