increase the engine coolant concentration above
60%. Leave a 50/50 mixture of engine coolant and
water in your vehicle year-round in non-extreme
climates.
CHECKING AND ADDING POWER STEERING
FLUID
Check the power
steering fluid. Refer to
the ªService Guideº for
the service interval
schedules. If adding
fluid is necessary, use
only MERCONtAT F.
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.
Perform steps 4 and 5 following the procedure for
your engine.

4. Check the fluid level
in the reservoir. It
should be between the
MIN and MAX lines. Do
not add fluid if the
level is within 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 and MAX lines. Be sure to
put the cap back on the reservoir.
TRANSMISSION FLUID
Checking automatic transmission fluid
Refer to your ªService Guideº for scheduled intervals
for fluid checks and changes. Your transaxle does
not consume fluid. However, the fluid level should
be checked if the transaxle is not working properly,
i.e., if the transaxle slips or shifts slowly or if you
notice some sign of fluid leakage.
Automatic transmission fluid expands when
warmed. To obtain an accurate fluid check,
drive the vehicle until it is warmed up
(approximately 30 km [20 miles]). If your
vehicle has been operated for an extended
period at high speeds, in city traffic during hot
weather or pulling a trailer, the vehicle should
be turned off for about 30 minutes to allow
fluid to cool before checking.
1. Drive the vehicle 30 km (20 miles) or until it
reaches normal operating temperature.

2. Park the vehicle on a level surface and engage the
parking brake.
3. With the parking brake engaged and your foot on
the brake pedal, start the engine and move the
gearshift lever through all of the gear ranges. Allow
sufficient time for each gear to engage.
4. Latch the gearshift lever in P (Park) and leave the
engine running.
5. Remove the dipstick, wiping it clean with a clean,
dry lint free rag.
6. Install the dipstick making sure it is fully seated in
the filler tube.
7. Remove the dipstick and inspect the fluid level.
The fluid should be in the designated areas for
normal and room temperature.
Low fluid level
Do not drive the
vehicle if the fluid level
is at the bottom of the
dipstick and the outside temperatures are above
10ÉC (50ÉF).
Correct fluid level
The transmission fluid should be checked at normal
operating temperatures 66ÉC-77ÉC (150ÉF-170ÉF) on
a level surface. The normal operating temperature
can be reached after approximately 30 km (20
miles) of driving.
The transmission fluid
should be in this range
if at normal operating
temperature (66ÉC-77ÉC [150ÉF-170ÉF]).

When lifting a plastic-cased battery,
excessive pressure on the end walls could
cause acid to flow through the vent caps, resulting
in personal injury and/or damage to the vehicle or
battery. Lift the battery with a battery carrier or
with your hands on opposite corners.
Keep batteries out of reach of children.
Batteries contain sulfuric acid. Avoid contact
with skin, eyes or clothing. Shield your eyes when
working near the battery to protect against
possible splashing of acid solution. In case of acid
contact with skin or eyes, flush immediately with
water for a minimum of 15 minutes and get
prompt medical attention. If acid is swallowed, call
a physician immediately.
Because your vehicle's engine is electronically
controlled by a computer, some control conditions
are maintained by power from the battery. When the
battery is disconnected or a new battery is installed,
the engine must relearn its idle conditions before
your vehicle will drive properly. To begin this
process:
1. Set your parking brake.
2. Put the gearshift in P (Park), turn off all
accessories and start the engine.
3. Let the engine idle for at least one minute.
4. The relearning process will automatically
complete as you drive the vehicle.
²If you do not allow the engine to relearn its idle,
the idle quality of your vehicle may be adversely
affected until the idle is eventually relearned.
Maintenance and care

²Automotive fuels can be harmful or fatal if
swallowed. Fuel such as gasoline is highly toxic
and if swallowed can cause death or permanent
injury. If fuel is swallowed, call a physician
immediately, even if no symptoms are immediately
apparent. The toxic effects of fuel may not be
visible for hours.
²Avoid inhaling fuel vapors. Inhaling too much fuel
vapor of any kind can lead to eye and respiratory
tract irritation. In severe cases, excessive or
prolonged breathing of fuel vapor can cause
serious illness and permanent injury.
²Avoid getting fuel liquid in your eyes. If fuel is
splashed in the eyes, remove contact lenses (if
worn), flush with water for 15 minutes and seek
medical attention. Failure to seek proper medical
attention could lead to permanent injury.
²Fuels can also be harmful if absorbed through the
skin. If fuel is splashed on the skin and/or
clothing, promptly remove contaminated clothing
and wash skin thoroughly with soap and water.
Repeated or prolonged skin contact with fuel
liquid or vapor causes skin irritation.
²Be particularly careful if you are taking
ªAntabuseº or other forms of disulfiram for the
treatment of alcoholism. Breathing gasoline
vapors, or skin contact could cause an adverse
reaction. In sensitive individuals, serious personal
injury or sickness may result. If fuel is splashed
on the skin, promptly wash skin thoroughly with
soap and water. Consult a physician immediately
if you experience an adverse reaction.
Fuel Filler Cap
Your fuel tank filler cap has an indexed design with
a one-eighth turn on/off feature.
When fueling your vehicle:
1. Turn the engine off.
Maintenance and care
156

2. Carefully turn the filler cap counterclockwise 1/8
of a turn until it stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with
the notches on the filler pipe.
5. Turn the filler cap clockwise 1/8 of a turn until it
stops.
If the ªService Engine Soon/Check Engine ª indicator
comes on and stays on when you start the engine,
the fuel filler cap may not be properly installed.
Turn off the engine, remove the fuel filler cap and
reinstall it being careful to align the cap properly.
If you must replace the fuel filler cap, replace
it with an authorized Motorcraft part. The
customer warranty may be void for any damage
to the fuel tank or fuel system if an authorized
Motorcraft fuel filler cap is not used.
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,
the pressure in the fuel tank can damage
the fuel system or cause it to work improperly in a
collision.

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 meet 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 for which
your vehicle was not designed may not be covered
by your warranty.
Octane recommendations
3.0L V6 Vulcan and Duratec engines
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
a qualified service technician to prevent any engine
damage.
87(R+M)/2 METHOD
Maintenance and care
158

3.4L-32V V8 SHO engine
Your vehicle is
designed to use
ªPremiumº gasoline
with an (R+M)/2
octane rating of 91 or higher for optimum
performance. Gasolines with lower octane ratings
can be used, but performance may decrease. We do
not recommend the use of gasolines labeled as
ªPremiumº in high altitude areas that are sold with
octane ratings of less than 91.
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
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 gasoline. ªPremiumº
unleaded gasoline should not be used (particularly in
the United States) if ªRegularº unleaded gasoline is
recommended 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 fuel specification to provide
information on high quality fuels that optimize the
performance of your vehicle. We recommend the use
of fuels 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.
Running out of fuel
Avoid running out fuel because this situation may
have an adverse affect on modern powertrain
components.
If you have run out of fuel:
²You may need to crank the engine several times
before the system starts to pump fuel from the
tank to the engine.
²Your ªService Engine Soonº light may come on.
For more information on the ªService Engine
Soonº light, refer to theInstrumentationchapter.
Fuel Filter
Your vehicle is equipped with a fuel filter that is
mounted on the underbody.
For fuel filter replacement, see your dealer or a
qualified service technician. Refer to the ªService
Guideº for the appropriate intervals for changing the
fuel filter.
If you replace the fuel filter, replace it 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.
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
Maintenance and care
160

exhaust emission standards. To make sure that the
catalytic converter and other emission control
components continue to work properly:
²Use only unleaded fuel.
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 your ªService Guideº
performed according to the specified schedule.
The scheduled maintenance items listed in the
ªService Guideº are 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.
Lumination 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.
