FUSE SPECIFICATION CHART
Power Distribution Box
WARNING:Always disconnect the battery before servicing high
current fuses.
WARNING:To reduce risk of electrical shock, always replace the
cover to the power distribution box before reconnecting the
battery or refilling fluid reservoirs.
The power distribution box is located in the engine compartment. It has
high-current fuses that protect your vehicle’s main electrical systems
from overloads.
If the battery has been disconnected and reconnected, seeChanging the
Vehicle Batteryin theMaintenancechapter.
The high-current fuses are coded as follows:

State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
CHANGING THE VEHICLE BATTERY
WARNING:Batteries normally produce explosive gases which
can cause personal injury. Therefore, do not allow flames, sparks
or lighted substances to come near the battery. When working near the
battery, always shield your face and protect your eyes. Always provide
proper ventilation.
WARNING: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.
WARNING: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.
WARNING:Battery posts, terminals and related accessories contain
lead and lead compounds.Note:Wash hands after handling.
Note: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.
Note:Electrical or electronic accessories or components added to the
vehicle by the dealer or the owner may adversely affect battery
performance and durability.

Your vehicle is equipped with a Motorcraftmaintenance-free battery
which normally does not require additional water during its life of service.
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.
It is recommended that the negative battery cable terminal be disconnected
from the battery if you plan to store your vehicle for an extended period of
time. This will minimize the discharge of your battery during storage.
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 and fuel trim strategy for optimum driveability and
performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P (Park), turn off all accessories and start the engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 10 miles (16 km) or more to
relearn the idle and fuel trim strategy.
•Note:If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle trim is
eventually relearned.
If the battery has been disconnected or a new battery has been installed,
the clock and radio settings must be reset once the battery is reconnected.
CHECKING THE WIPER BLADES
Run the tip of your fingers over the edge of the blade
to check for roughness.
Clean the wiper blades with washer fluid or water
applied with a soft sponge or cloth.

WAXING
•Wash the vehicle first.
•Use a quality wax that does not contain abrasives.
•Do not allow paint sealant to come in contact with any non-body
(low-gloss black) colored trim, such as grained door handles, roof
racks, bumpers, side moldings, mirror housings or the windshield cowl
area. The paint sealant will gray or stain the parts over time.
REPAIRING MINOR PAINT DAMAGE
Your authorized dealer has touch-up paint to match your vehicle’s color.
Take your color code (printed on a sticker in the driver’s door jamb) to
your authorized dealer to make sure you get the correct color.
•Remove particles, such as bird droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout, before repairing paint chips.
•Always read the instructions before using the products.
CLEANING THE ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal.
When washing:
•Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
•Spray MotorcraftEngine Shampoo and Degreaser on all parts that
require cleaning and pressure rinse clean. In Canada, use Motorcraft
Engine Shampoo.
•Never wash or rinse the engine while it is hot or running; water in the
running engine may cause internal damage.
•Never wash or rinse any ignition coil, spark plug wire or spark plug
well, or the area in and around these locations.
•Cover the battery, power distribution box, and air filter assembly to
prevent water damage when cleaning the engine.
