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 fillups 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 Capacitieschart in this
ªOwner Guideº. 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.

Driving style Ð good driving and fuel economy
habits
Give consideration to the lists that follow and you
may be able to change a number of variables and
improve your fuel economy.
Habits
²Smooth, moderate operation can yield up to 10%
savings in fuel.
²Steady speeds without stopping will usually give
the best fuel economy.
²Idling for long periods of time (greater than one
minute) may waste fuel.
²Anticipate stopping; slowing down may eliminate
the need to stop.
²Sudden or hard accelerations may reduce fuel
economy.
²Slow down gradually.
²Driving at reasonable speeds (traveling at 88 km/h
[55 mph] uses 15% less fuel than traveling at
105 km/h [65 mph]).
²Revving the engine before turning it off may
reduce fuel economy.
²Using the air conditioner or defroster may reduce
fuel economy.
²Using speed control (if equipped) may improve
fuel economy. Speed control can help maintain a
constant speed and reduce speed changes. You
may want to turn off the speed control in hilly
terrain as unnecessary shifting between third and
fourth gears may occur and could result in
reduced fuel economy.
²Warming up a vehicle on cold mornings is not
required and may reduce fuel economy.
²Resting your foot on the brake pedal while driving
may reduce fuel economy.
Maintenance and care
173

²Combine errands and minimize stop-and-go
driving.
Maintenance
²Keep tires properly inflated and use only
recommended size.
²Operating a vehicle with the wheels out of
alignment will reduce fuel economy.
²Use recommended engine oil. Refer toLubricant
Specifications.
²Perform all regularly scheduled maintenance
items. Follow the recommended maintenance
schedule and owner maintenance checks found in
your vehicle Scheduled Maintenance Guide.
Conditions
²Heavily loading a vehicle or towing a trailer may
reduce fuel economy at any speed.
²Carrying unnecessary weight may reduce fuel
economy (approximately 2 km/h [1 mpg] is lost
for every 180 kg [400 lb] of weight carried).
²Adding certain accessories to your vehicle (for
example bug deflectors, rollover/light bars,
running boards, ski/luggage racks) may reduce
fuel economy.
²Using fuel blended with alcohol may lower fuel
economy.
²Fuel economy may decrease with lower
temperatures during the first 12±16 km
(8±10 miles) of driving.
²Driving on flat terrain offers improved fuel
economy as compared to driving on hilly terrain.
²Transmissions give their best fuel economy when
operated in the top cruise gear and with steady
pressure on the gas pedal.
²Close windows for high speed driving.
Maintenance and care
174

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 charging system warning light,
ªService Engine Soonº light or the temperature
warning light, fluid leaks, strange odors, smoke or
loss of oil pressure, 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, sells, leases,
trades vehicles, or supervises a fleet of vehicles are
not permitted to intentionally remove an emission
control device or prevent it from working.
Information about your vehicle's emission system is
on the Vehicle Emission Control Information Decal
located on or near the engine. This decal identifies
engine displacement and gives some tune up
specifications.
Please consult your ªWarranty Guideº for complete
emission warranty information.
Readiness for Inspection/Maintenance (I/M)
testing
In some localities, it may be a legal requirement to
pass an I/M test of the on-board diagnostics system.
If your ªCheck Engine/Service Engine Soonº light is
on, refer to the description in theWarning Lights
and Chimessection of theInstrumentation
chapter. Your vehicle may not pass the I/M test with
the ªCheck Engine/Service Engine Soonº light on.
Maintenance and care
176

If the vehicle's powertrain system or its battery has
just been serviced, the on-board diagnostics system
is reset to a ªnot ready for I/M testº condition. To
ready the on-board diagnostics system for I/M
testing, a minimum of 30 minutes of city and
highway driving is necessary as described below:
²First, at least 10 minutes of driving on an
expressway or highway.
²Next, at least 20 minutes driving in stop-and-go,
city-type traffic with at least four idle periods.
Allow the vehicle to sit for at least eight hours
without starting the engine. Then, start the engine
and complete the above driving cycle. The engine
must warm up to its normal operating temperature.
Once started, do not turn off the engine until the
above driving cycle is complete.
EXTERIOR BULBS
Replacing exterior bulbs
Check the operation of the following lamps
frequently:
²Headlamps
²Tail lamps
²Brakelamps
²High-mount brakelamp
²Turn signals
²Backup lamps
²License plate lamp
Do not remove lamp bulbs unless they will be
replaced immediately. If a bulb is removed for an
extended period of time, contaminants may enter
the lamp housings and affect performance.

Repairing paint chips
Minor scratches or paint damage from road debris
may be repaired with the Ultra Touch Prep and
Finishing Kit (#F7AZ-19K507±BA), touch-up paint
(#ALBZ-19500±XXXXA), or aerosol paint spray
(#ALAZ-19500±XXXXA) from the Ford Car Care
Chemicals line. Please note that the part numbers
(shown as XXXX above) will vary with your vehicle's
specific coloring. Observe the application
instructions on the products.
Remove particles such as bird droppings, tree sap,
insect remains, tar spots, road salt and industrial
fallout immediately.
Cleaning the wheels
Wash with the same detergent as the body of your
vehicle. Do not use acid-based or alcohol-based
wheel cleaners, steel wool, fuel or strong detergents.
Never use abrasives that will damage the finish of
special wheel surfaces. Use a tar remover to remove
grease and tar.
The brushes used in some automatic car washes may
damage the finish on your wheels. Before going to a
car wash, find out if the brushes are abrasive.
Cleaning the engine
In order to identify your vehicle's engine, refer to
Identifying components in the engine
compartmentin the Maintenance and Care chapter.
Engines are more efficient when they are clean
because grease and dirt buildup keep the engine
warmer than normal. When washing:
²Take care when using a power washer to clean
the engine. The high pressure fluid could
penetrate the sealed parts and cause damage.
²Do not spray with cold water to avoid cracking
the engine block or other engine components.

²Never wash or rinse the engine while it is
running; water in the running engine may cause
internal damage.
Cleaning plastic exterior parts
Use vinyl cleaner for routine cleaning. Clean with a
tar remover if necessary. Do not clean plastic parts
with thinners, solvents or petroleum-based cleaners.
Cleaning the exterior lamps
Wash with the same detergent as the exterior of
your vehicle. Use glass cleaner or tar remover if
necessary.
To avoid scratching the lamps, do not use a dry
paper towel, chemical solvents or abrasive cleaners.
Cleaning the wiper blades and windshield
If the wiper blades do not wipe properly, clean the
wiper blade rubber element with undiluted
windshield washer solution or a mild detergent. To
avoid damaging the blades, do not use fuel,
kerosene, paint thinner or other solvents.
If the wiper still does not wipe properly, this could
be caused by substances on the windshield such as
tree sap and some hot wax treatments used by
commercial car washes. Clean the outside of the
