If you cannot find unleaded fuel or can only get fuel
with an anti-knock index lower than is
recommended for your vehicle, contact a district or
owner relations/customer relationship office.
The use of leaded fuel in your vehicle without
proper conversion may damage the effectiveness of
your emission control system and may cause engine
knocking or serious engine damage. Ford Motor
Company/Ford of Canada is not responsible for any
damage caused by use of improper fuel.
In the United States, using leaded fuel may also
result in difficulty importing your vehicle back into
the U.S.

California Civil Code Section 1793.2(d) requires that,
if a manufacturer or its representative is unable to
repair a motor vehicle to conform to the vehicle’s
applicable express warranty after a reasonable
number of attempts, the manufacturer shall be
required to either replace the vehicle with one
substantially identical or repurchase the vehicle and
reimburse the buyer in an amount equal to the
actual price paid or payable by the consumer (less a
reasonable allowance for consumer use). The
consumer has the right to choose whether to receive
a refund or replacement vehicle.
California Civil Code Section 1793.22(b) presumes
that the manufacturer has had a reasonable number
of attempts to conform the vehicle to its applicable
express warranties if, within the first 18 months of

REPORTING SAFETY DEFECTS (U.S. ONLY)
If you believe that your
vehicle has a defect
which could cause a
crash or could cause injury or death, you should
immediately inform the National Highway Traffic
Safety Administration (NHTSA) in addition to
notifying Ford Motor Company.
If NHTSA receives similar complaints, it may open
an investigation, and if it finds that a safety defect
exists in a group of vehicles, it may order a recall
and remedy campaign. However, NHTSA cannot
become involved in individual problems between
you, your dealer, or Ford Motor Company.
To contact NHTSA, you may either call the Auto
Safety Hotline toll-free at 1–800–424–9393 (or
366–0123 in the Washington D.C. area) or write to:
NHTSA

vehicle safety from the Hotline.

SERVICE RECOMMENDATIONS
To help you service your vehicle:
•We highlight do-it-yourself items in the engine
compartment for easy location.
•We provide a scheduled maintenance guide which
makes tracking routine service easy.
If your vehicle requires professional service, your
dealership can provide the necessary parts and
service. Check yourWarranty Guide/Owner
Information Guideto 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.
•Do not work on a hot engine.
•When the engine is running, keep loose clothing,
jewelry or long hair away from moving parts.
•Do not work on a vehicle with the engine running
in an enclosed space, unless you are sure you
have enough ventilation.
•Keep 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 in theBatterysection in
this chapter.
Working with the engine off
•Automatic transmission:
1. Set the parking brake and ensure the gearshift is
securely latched in P (Park).
Maintenance and Specifications

•4.6LSOHCV8 engine
•Oil levels above the MAX mark 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 to
Checking the engine oilin this chapter.
2. If the engine oil level is not within the normal
range, add only certified engine oil of the
recommended viscosity. Remove the engine oil filler
cap and use a funnel to pour the engine oil into the
opening.
3. Recheck the engine oil level. Make sure the oil
level is not above the MAX mark on the engine oil
level indicator (dipstick).
4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the
filler cap clockwise 1/4 of a turn until three clicks
are heard or until the cap is fully seated.

BATTERY
Your vehicle is
equipped with a
Motorcraft
maintenance-free
battery which normally
does not require
additional water during
its life of service.
However, for severe usage or in high temperature
climates, check the battery electrolyte level. Refer to
the scheduled maintenance guide for the service
interval schedules.
Keep the electrolyte level 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 mineral or
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.
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.
Maintenance and Specifications

•4.6L SOHC V8
engine
When the engine is cold, check the level of the
engine coolant in the reservoir.
•The engine coolant should be at the“cold fill
level”as listed on the engine coolant reservoir.
•Refer to the scheduled maintenance guide for
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 to
Adding 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.
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.
Maintenance and Specifications
207

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.
The cooling system in your vehicle is filled with
either green-colored Motorcraft Premium Engine
Coolant meeting Ford specification ESE-M97B44–A
or yellow-colored Motorcraft Premium Gold Engine
Coolant meeting Ford Specification
WSS-M97B51–A1. To determine your vehicle’s
coolant type (color), check your coolant reservoir.
•Add Motorcraft Premium Engine Coolant
(green-colored), VC-4–A (U.S.) or CXC-10
(Canada) or Motorcraft Premium Gold
Engine Coolant (yellow-colored), VC-7–A
(VC-7–B in Oregon), depending on the type
of coolant originally equipped in your
vehicle.If you are unsure which type of coolant
your vehicle requires, check your coolant
reservoir or contact your local dealer.
Note:Use of Motorcraft Cooling System Stop Leak
Pellets, VC-6, darkens the color of Motorcraft
Premium Gold Engine Coolant from yellow to golden
tan.
•Do not add/mix an orange-colored, extended
life coolant such as Motorcraft Speciality
Orange Engine Coolant, VC-2 (US) or
CXC-209 (Canada), meeting Ford
specification WSS-M97B44–Dwiththe
factory-filled coolant.Mixing Motorcraft
Speciality Orange Engine Coolant or any
orange-colored extended life product 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
