3. Connect the negative (-) cable to the negative (-)
terminal of the assisting battery.
4. Make the final connection of the negative (-)
cable. For the 3.0L Vulcan, make the connection to
an exposed metal part of the stalled vehicle's engine,
away from the battery and the carburetor/fuel
injection system. For the 3.0L Duratec, make the
connection to the hood latch of the disabled engine,
away from the battery and the carburetor/fuel
injection system.
The preferred locations of an exposed metal part (to
groundthe circuit) are the alternator mounting
brackets or an engine liftingeye.Do notuse fuel
lines, engine rocker covers or the intake manifold as
groundingpoints.
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.

SERVICE RECOMMENDATIONS
To help you service your vehicle:
²We highlight do-it-yourself items in the engine
compartment for easy location.
²We provide a Scheduled Maintenance Guide 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, keep loose clothing,
jewelry or long hair away from 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 in theBatterysection in
this chapter.
Working with the engine off
1. Set the parking brake, and ensure the gearshift is
securely latched in park.
2. Turn off the engine and remove the key.
Maintenance and care
135

Do not let the reservoir for the master
cylinder run dry. This may cause the brakes
to fail.
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.
Checking and adding washer fluid for the
liftgate (if equipped)
The opening for the reservoir is located on the
passenger side under the tail lamp. Refill this
reservoir with the same fluid you use for your
windshield.
Maintenance and care

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.
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. Set your parking brake.
2. Put the gearshift in P (Park), turn off all
accessories and start the engine.
3. Let the engine idle for at least one minute.
4. The relearning process will automatically
complete as you drive the vehicle.
²The vehicle may need to be driven 16 km
(10 miles) or more to relearn the idle and fuel
trim strategy.
²If 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 the preset
radio stations must be reset once the battery is
reconnected.

²Always dispose of
automotive batteries
in a responsible
manner. Follow your
local authorized
standards for
disposal. Call your
local authorized
recycling center to find out more about recycling
automotive batteries.
WINDSHIELD WIPER BLADES
Check the wiper blades at least twice a year or when
they seem less effective. Substances such as tree sap
and some hot wax treatments used by commercial
car washes reduce the effectiveness of wiper blades.
Checking the wiper blades
If the wiper blades do not wipe properly, clean both
the windshield and wiper blades using undiluted
windshield wiper solution or a mild detergent. Rinse
thoroughly with clean water. To avoid damaging the
blades, do not use fuel, kerosene, paint thinner or
other solvents.
Changing the wiper blades
To replace the wiper blades:
1. Pull the wiper arm
away from the
windshield and lock
into the service
position.
2. Turn the blade at an
angle from the wiper
arm. Push the lock pin
manually to release the
blade and pull the
wiper blade down
toward the windshield
to remove it from the arm.

SNOW TIRES AND CHAINS
Snow tires must be the same size and grade
as the tires you currently have on your
vehicle.
The tires on your vehicle have all weather treads to
provide traction in rain and snow. However, in some
climates, you may need to use snow tires and
chains. If you need to use chains, it is recommended
that steel wheels (of the same size and
specifications) be used as chains may chip aluminum
wheels.
Follow these guidelines when using snow tires and
chains:
²Use only SAE Class S chains.
²Install chains securely, verifying that the chains do
not touch any wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the chains rub or
bang against your vehicle, stop and re-tighten the
chains. If this does not work, remove the chains
to prevent damage to your vehicle.
²If possible, avoid fully loading your vehicle.
²Remove the tire chains when they are no longer
needed. Do not use tire chains on dry roads.
²The suspension insulation and bumpers will help
prevent vehicle damage. Do not remove these
components from your vehicle when using snow
tires and chains.

Important safety precautions
Do not overfill the fuel tank. The pressure in
an overfilled tank may cause leakage and
lead to fuel spray and fire.
