Do not use supplemental engine oil additives, cleaners or other engine
treatments. They are unnecessary and could lead to engine damage that
is not covered by Ford warranty.
Change your engine oil and filter according to the appropriate schedule
listed inscheduled maintenance information.
When changing the oil filter on the 2.3L engine, you must also replace
the filter cap O-ring. The oil filter drain plug O-ring must also be
replaced whenever the oil filter drain plug is removed. Reuse of the
O-rings may cause engine oil leakage and may result in severe engine
damage. The customer warranty may be void for any damage to the
engine if the O-rings are not replaced.
Ford production and Motorcraft replacement oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, start-up
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter or
another with equivalent performance for your engine application.
BATTERY
Your vehicle is equipped with a
Motorcraft maintenance-free battery
which normally does not require
additional water during its life of
service.
If your battery has a cover/shield, make sure it is reinstalled
after the battery has been cleaned or replaced.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.

FILL RANGE” in the coolant reservoir. If the level falls below, add
coolant per the instructions in theAdding engine coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50/50 mixture of coolant and water provides the following:
•Freeze protection down to -34°F (-36°C).
•Boiling protection up to 265°F (129°C).
•Protection against rust and other forms of corrosion.
•Proper function of calibrated gauges.
When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the “FULL COLD” level or within the
“COLD FILL RANGE” as listed on the engine coolant reservoir
(depending upon application).
•Refer toscheduled maintenance informationfor service interval
schedules.
•Be sure to read and understandPrecautions when servicing your
vehiclein this chapter.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool,until the appropriate fill level is obtained.

WARNING:Do not add engine coolant when the engine is hot.
Steam and scalding liquids released from a hot cooling system
can burn you badly. Also, you can be burned if you spill coolant on hot
engine parts.
WARNING:Do not put engine coolant in the windshield washer
fluid container. If sprayed on the windshield, engine coolant
could make it difficult to see through the windshield.
•Add Motorcraft Premium Gold Engine Coolant or equivalent
meeting Ford specification WSS-M97B51-A1.Refer to
Maintenance product specifications and capacitiesin this chapter.
Note:Use of Motorcraft Cooling System Stop Leak Pellets or an
equivalent product meeting Ford specification WSS-M99B37-B6, may
darken the color of Motorcraft Premium Gold Engine Coolant from
yellow to golden tan.
Note:When adding more than 1 quart (1.0 liter) of coolant it is
necessary to use the coolant bleed valve. Failure to bleed the cooling
system when adding engine coolant may cause engine damage. Refer to
the Cooling section of theWorkshop Manual.
•Do not add/mix an orange-colored, extended life coolant such
as Motorcraft Specialty Orange Engine Coolant, meeting Ford
specification WSS-M97B44-D, or DEX-COOL
brand with the
factory-filled coolant.Mixing Motorcraft Specialty Orange Engine
Coolant or any orange-colored extended life product such as
DEX-COOL
brand with your factory filled coolant can result in
degraded corrosion protection.
•A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.
•Do not use alcohol, methanol, brine or any engine coolants
mixed with alcohol or methanol antifreeze (coolant).Alcohol
and other liquids can cause engine damage from overheating or
freezing.
•Do not add extra inhibitors or additives to the coolant.These
can be harmful and compromise the corrosion protection of the engine
coolant.

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 approved 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 endorses the use of reformulated “cleaner-burning” gasolines to
improve air quality, per the recommendations in theChoosing the right
fuelsection.
Running out of fuel
Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.
If you have run out of fuel:
•You 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. On restarting, cranking time will take a few seconds longer
than normal.
•Normally, adding 1 gallon (3.8L) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than
1 gallon (3.8L) may be required.
•TheService engine soon
indicator may come on. For more
information on theService engine soon
indicator, refer to
Warning lights and chimesin theInstrument Clusterchapter.
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 1,000 miles
(1,600 km) of driving (engine break-in period). You will get a more
accurate measurement after 2,000 miles–3,000 miles
(3,000 km–5,000 km).

•Avoid running out of fuel.
•Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
•Have the items listed inscheduled maintenance information
performed according to the specified schedule.
The scheduled maintenance items listed inscheduled maintenance
informationare 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.
WARNING: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 theService engine soon
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.
An improperly operating or damaged exhaust system may allow exhaust
to enter the vehicle. Have a damaged or improperly operating exhaust
system inspected and repaired immediately.
WARNING: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 also lists engine displacement.
Please consult yourWarranty Guide/Customer Information Guidefor
complete emission warranty information.
On board diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the On
2009 Milan(mln)
Owners Guide, 2nd Printing

Board Diagnostics System (OBD-II). The OBD-II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists your
authorized dealer in properly servicing your vehicle. When theService
engine soon
indicator illuminates, the OBD-II system has detected
a malfunction. Temporary malfunctions may cause theService engine
soon
indicator 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—the engine may misfire or run
poorly.
3. The fuel cap may not have been securely tightened. SeeFuel filler
capin this chapter.
4. Driving through deep water—the electrical system may be wet.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel, properly tightening the fuel cap or letting the
electrical system dry out. After three driving cycles without these or any
other temporary malfunctions present, theService engine soon
indicator should stay off the next time the engine is started. A driving
cycle consists of a cold engine startup followed by mixed city/highway
driving. No additional vehicle service is required.
If theService engine soon
indicator remains on, have your vehicle
serviced at the first available opportunity. Although some malfunctions
detected by the OBD-II may not have symptoms that are apparent,
continued driving with theService engine soon
indicator on can
result in increased emissions, lower fuel economy, reduced engine and
transmission smoothness, and lead to more costly repairs.
Readiness for Inspection/Maintenance (I/M) testing
Some state/provincial and local governments may have
Inspection/Maintenance (I/M) programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection could prevent
you from getting a vehicle registration. Your vehicle may not pass the I/M
test if theService engine soon
indicator is on or not working
properly (bulb is burned out), or if the OBD-II system has determined
that some of the emission control systems have not been properly
checked. In this case, the vehicle is considered not ready for I/M testing.
If theService engine soon
indicator is on or the bulb does not
work, the vehicle may need to be serviced. Refer to the On board
diagnostics (OBD-II) description in this chapter.

If the vehicle’s engine or transmission has just been serviced, or the
battery has recently run down or been replaced, the OBD-II system may
indicate that the vehicle is not ready for I/M testing. To determine if the
vehicle is ready for I/M testing, turn the ignition key to the on position
for 15 seconds without cranking the engine. If theService engine
soon
indicator blinks eight times, it means that the vehicle is not
ready for I/M testing; if theService engine soon
indicator stays on
solid, it means that the vehicle is ready for I/M testing.
The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway/highway followed by
20 minutes of stop-and-go driving with at least four 30-second 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. If
the vehicle is still not ready for I/M testing, the above driving cycle will
have to be repeated.

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/MAX or upper and lower 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/MAX or upper and
lower lines. Be sure to put the cap back on the reservoir. Refer to
Maintenance product specifications and capacitiesin this chapter for
the proper fluid type.
BRAKE/CLUTCH FLUID
Brake and clutch systems are supplied from the same reservoir.
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
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.
