WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member, your roadside assistance center.
If equipped with air suspension, the air suspension control must be
turned to the OFF position.
The Ford approved towing procedure is flatbed or wheel lift with
dollies.
On 4x2 vehicles, it is acceptable to tow the vehicle with the front wheels
on the ground (without dollies) and the rear wheels off the ground.
If the vehicle is towed by other means or incorrectly, vehicle
damage may occur.
Do not tow with slingbelt equipment. Ford Motor Company has not
developed or approved a slingbelt towing procedure.

SERVICE RECOMMENDATIONS
To help you service your vehicle:
²We highlight do-it-yourself items in the engine compartment for easy
location.
²We provide a ``Service Guide'' which makes tracking routine service
easy.
If your vehicle requires professional service, your dealership can provide
necessary parts and service. Check your ``Warranty Guide'' 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 ``relearn'' its idle
conditions before your vehicle will drive properly, as explained inBattery
in this chapter.
Working with the engine off
²Automatic transmission:
1. Set the parking brake and
ensure the gearshift is securely latched in P (Park).
2. Turn off the engine and remove the key.

²If the oil level isbetween the ADD and FULL marks (4.0L
engines)orbetween the MIN and MAX marks (5.0L engines)
the oil level is acceptable.DO NOT ADD OIL.
²If the oil level is below the ADD
mark (4.0L engines) or MIN mark
(5.0L engines), add enough oil to
raise the level within the
ADD-FULL range (4.0L engines)
or MIN-MAX range (5.0L
engines).
²Oil levels above the letter F in FULL (4.0L engines) or the MAX mark
(5.0L engines) may cause engine damage. Some oil must be removed
from the engine by a service technician.
7. Put the indicator back in and ensure it is fully seated.
Adding engine oil
1. Check the engine oil. For instructions, refer toChecking the engine
oilin this chapter.
2. If the fluid level is not within the normal range, add only certified
engine oil of the preferred viscosity. Add engine oil through the oil filler
cap. Remove the filler cap and use a funnel to pour oil in the opening.
3. Recheck the oil level. Make sure the oil level is not above the MAX
mark or the letter F in FULL on the dipstick.

Engine oil recommendations
Look for this certification mark.
Ford oil specification is WSS-M2C153-G.
Use SAE 5W-30 motor oil certified for gasoline engines by the American
Petroleum Institute.
Do not use supplemental engine oil additives, oil treatments or engine
treatments. They are unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your warranty.
Changing the engine oil and filter
Change your engine oil and filter according to the following mileage and
time requirements, whichever occurs first:
²Normal Schedule ± 8,000 km (5,000 miles) or six months.
²Severe Duty Schedule - 5,000 km (3,000 miles) or three months.
Severe duty operation would include extensive idling, trailer towing,
driving in severe dust and police, taxi or delivery service.
Ford production and aftermarket (Motorcraft) 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, startup
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.
Maintenance and care

²5.0L engine
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge will be near the
center of the NORMAL band).
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.
5.If your vehicle is equipped with a 4.0L EFI engine,the fluid level
should be in the FULL HOT range. Do not add fluid if the level is in this
range.
6.If your vehicle is equipped with a 4.0L SOHC engine or a 5.0L
engine,the fluid level should be between the MIN and MAX lines. Do
not add fluid if the level is in this range.
7. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the correct operating range. Be sure to put the
cap back on the reservoir.
TRANSMISSION FLUID
Checking and adding automatic transmission fluid
Follow the scheduled service intervals outlined in the ``Service Guide''.
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and/or dipstick handle
and also in theLubricant specificationssection in theCapacities and
specificationschapter.

DRIVELINE UNIVERSAL JOINT AND SLIP YOKE
The universal joints standard with your vehicle do not require
lubrication. If the original universal joints are replaced with universal
joints equipped with grease fittings, lubrication will be necessary.
BATTERY
Your vehicle may be equipped with a
Superstart maintenance-free battery.
If the original equipment battery
needs replacing, it may be replaced
with a low-maintenance battery. The
low-maintenance battery normally
does not require additional water
during its life of service. However,
for severe usage or in high
temperature climates, check your
battery electrolyte level, at least
every 24 months or 40,000 km
(24,000 miles). Keep the electrolyte
in each cell up to the ``level'' indicator. Do not overfill the battery cells.
If the electrolyte level in the battery is low, you can add plain tap water
to the battery, as long as you do not use hard water (water with a high
alkali content). If possible, however, try to only fill the battery cells with
distilled water. If the battery needs water often, have the charging
system checked.
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 terminal(s) and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water. Reinstall the cables when
you are done cleaning them, and apply a small quantity of grease to the
top of each battery terminal to help prevent corrosion.
If your battery has a cover/shield, make sure it is reinstalled
after the battery is replaced.
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

toward the windshield to remove it
from the arm.
3. Attach the new wiper to the
wiper arm and press it into place
until a click is heard.
INFORMATION ABOUT TIRE QUALITY GRADES
New vehicles are fitted with tires
that have their Tire Quality Grade
(described below) molded into the
tire's sidewall. These Tire Quality
Grades are determined by standards
that the United States Department
of Transportation has set.
Tire Quality Grades apply to new
pneumatic tires for use on
passenger cars. They do not apply
to deep tread, winter-type snow
tires, space-saver or temporary use
spare tires, tires with nominal rim
diameters of 10 to 12 inches or limited production tires as defined in
Title 49 Code of Federal Regulations Part 575.104(c)(2).
U.S. Department of Transportation-Tire quality grades:The U.S.
Department of Transportation requires Ford to give you the following
information about tire grades exactly as the government has written it.
Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified
government test course. For example, a tire grade 150 would wear one
and one-half (1 1/2) times as well on the government course as a tire

grade 100. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices, and
differences in road characteristics and climate.
Traction A B C
The traction grades, from highest to lowest are A, B, and C, and they
represent the tire's ability to stop on wet pavement as measured under
test surfaces of asphalt and concrete. A tire marked C may have poor
traction performance.
The traction grade assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering
(turning) traction.
Temperature A B C
The temperature grades are A (the highest), B, and C, representing the
tire's resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
The temperature grade for this tire is established for a tire that
is properly inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
SERVICING YOUR TIRES
Checking the tire pressure
²Use an accurate tire pressure gauge.
²Check the tire pressure when tires are cold, after the vehicle has been
parked for at least one hour or has been driven less than 5 km (3
miles).
