Power distribution box
The power distribution box is located in the engine compartment. The
power distribution box contains high-current fuses that protect your
vehicle's main electrical systems from overloads.
Always disconnect the battery before servicing high current

JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Do not push start your vehicle. You could damage the catalytic
converter.
Batteries contain sulfuric acid which burns skin, eyes, and
clothing.
Preparing your vehicle
Also see the label on the battery.
1. Use only a 12±volt supply to start your vehicle. If you connect your
battery to a 24±volt power supply you can damage your starter, ignition
system and other electrical components.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle's electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure theydo nottouch. Set the parking brake on both vehicles
and stay clear of the engine cooling fan and other moving parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.

Connecting the jumper cables
1. Position the vehicles so that they
do not touch one another.
2. Switch off the engine. Switch off
any unnecessary electrical
equipment.
3. Connect the positive (+) terminal
of the discharged battery (1) to the
positive (+) terminal of the booster
battery (2).
4. Connect one end of the second
lead to the negative (-) terminal of
the booster battery (3) and the
other end to a metal part of the
engine to be started (4), not to the
negative (-) terminal of the
discharged battery.
5. Make sure that the jump leads are clear of moving parts of the engine.
Do not connect the end of the second cable to the negative (-)
terminal of the battery to be jumped. A spark may cause an
explosion of the gases that surround the battery.
Jump starting
1. Start the booster vehicle and run the engine at moderately increased
speed.
2. Start the engine of the vehicle with the discharged battery.
3. Once the engine has been started, run both vehicles for a further
three minutes before disconnecting the leads.

Removing the jumper cables
1. Remove the jumper cables in
reverse order. Take the cable off the
metallic surface (1) first, followed
by the cable on the negative (-)
booster battery terminal (2).
2. Remove the cable from the
positive (+) terminal of the booster
battery (3) and then the discharged
battery (4).
3. After the disabled vehicle has
been started, allow it to idle for a
while so the engine can ªrelearnº its
idle conditions.

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.

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 ªlevelº 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
relearn its idle conditions before your vehicle will drive properly. To
begin this process:
1. Put the gearshift in P (Park), turn off all accessories and start the
vehicle.
2. Let the engine idle for at least one minute.
