SERVICE RECOMMENDATIONS
To help you service your vehicle:
²We highlight do-it-yourself items in the engine compartment for easy
location.
²We provide a ªService Guideº which makes tracking routine service
easy.
If your vehicle requires professional service, your dealership can provide
necessary parts and service. Check your ªWarranty Guideº to find out
which parts and services are covered.
Use only recommended fuels, lubricants, fluids and service parts
conforming to specifications. Motorcraft parts are designed and built to
provide the best performance in your vehicle.
PRECAUTIONS WHEN SERVICING YOUR VEHICLE
Be especially careful when inspecting or servicing your vehicle.
²Do not work on a hot engine.
²When the engine is running, make sure that loose clothing, jewelry or
long hair does not get caught up in moving parts.
²Do not work on a vehicle with the engine running in an enclosed
space, unless you are sure you have enough ventilation.
²Keep all lit cigarettes, open flames and other lit material away from
the battery and all fuel related parts.
If you disconnect the battery, the engine must ªrelearnº its idle
conditions before your vehicle will drive properly, as explained inBattery
in this chapter.
Working with the engine off
1. Set the parking brake and ensure the gearshift is securely latched in P
(Park).
2. Turn off the engine and remove the key.
3. Block the wheels to prevent the vehicle from moving unexpectedly.

WINDSHIELD WASHER FLUID
Checking and adding washer fluid
Check the washer fluid whenever
you stop for fuel. The reservoir is
highlighted with a
symbol.
If the level is low, add enough fluid
to fill the reservoir. In very cold
weather, do not fill the reservoir all
the way.
Do not put engine coolant in the container for the windshield
washer fluid.
ENGINE COOLANT
Check the level of the engine
coolant in the reservoir at least once
a month. Be sure to read and
understandPrecautions when
servicing your vehiclein this
chapter.
If the engine coolant has not been checked for a long period of time, the
engine coolant reservoir may eventually empty. If this occurs, add engine
coolant to the reservoir. For more information on engine coolant

How fail-safe cooling works
If the engine overheats, the engine
will automatically switch to
alternating cylinder operation. Each
disabled cylinder acts as an air
pump and cools the engine.
When this occurs, the engine coolant temperature gauge will move into
the red area, the
,and the service engine soon lights will
illuminate.
The vehicle will still operate, but will have limited engine power and no
air conditioning capability.
Continued operation will increase engine temperature and cause the
engine to completely shut down. The vehicle will coast to a stop.
As the engine temperature cools, the engine may be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
When fail-safe mode is activated
²Pull off the road as soon as possible.
²Immediately turn the engine off to prevent severe engine damage.
²Wait for the engine to cool.
²Check the coolant level.

²Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin, promptly remove contaminated clothing and
wash skin thoroughly with soap and water.
²If fuel is splashed in the eyes, remove contact lenses, flush with water
for 15 minutes and seek medical attention.
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. Consult a physician
immediately.
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 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 that your vehicle was not
designed for may not be covered by your warranty.
Octane recommendations
Your vehicle is designed to use
ªRegularº unleaded with an (R+M)/2
octane rating of 87. We do not
recommend gasolines labeled as
ªRegularº in high altitude areas that
are sold with octane ratings of 86 or
even less.
Do not be concerned if your vehicle sometimes knocks lightly. However,
if it knocks heavily under most driving conditions on fuel with the
recommended octane, see your dealer or a qualified service technician to
prevent any engine damage.

Maintenance and care

Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems during a cold start, try a different brand of ªRegularº gasoline.
ªPremiumº 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.
The American Automobile Manufacturers Association (AAMA) issued a
gasoline specification to provide information on high quality fuels that
optimize the performance of your vehicle. We recommend the use of
gasolines 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.
You may need to crank the engine several times before the system starts
to pump fuel from the tank to the engine. If you run out of fuel, your
Service Engine Soon light may come on. For more information on the
Service Engine Soon light, refer to theInstrumentationchapter.
Calculating fuel economy
To accurately calculate your vehicle's fuel economy:
1. Fill the tank completely and record the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added
(in liters or gallons).
3. After at least three to five fuel tank fill-ups, fill the fuel tank and
record the current mileage reading.
