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 the
Batterysection in this chapter.
Working with the engine off
1. Set the parking brake and
ensure the gearshift is securely

recovery reservoir-DO NOT ADD
DIRECTLY TO THE RADIATOR.
Add straight water only in an
emergency, but you should replace
it with a 50/50 mixture of coolant
and distilled water as soon as
possible.
Check the coolant level in the
coolant recovery reservoir the next
few times you drive the vehicle. If
necessary, add enough of a 50/50
mixture of coolant and water to
bring the liquid level to the fill line
on the reservoir.
Never remove the coolant
recovery cap while the
engine is running or hot.
If you must remove the coolant
recovery cap, follow these steps to
avoid personal injury:
1. Before you remove the cap, turn
the engine off and let it cool.
2. When the engine is cool, wrap a
thick cloth around the cap. Slowly
turn cap counterclockwise until
pressure begins to release.
3. Step back while the pressure
releases.
4. When you are sure that all the
pressure has been released, use
the cloth to turn it
counterclockwise and remove the
cap.

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.
3. The relearning process will
automatically complete as you
drive the vehicle.
²If you do not allow the engine to
relearn its idle, the idle quality
of your vehicle may be adversely
affected until the idle is
eventually relearned.
²If 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
community's standards for
disposal. Call your local
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
When replacing wiper blade
assemblies, always use a
Motorcraft part or equivalent. To
make replacing the wipers easy,
turn the ignition to ACC, then turn
the wipers on. When the wipers
reach the vertical position, turn
the ignition to LOCK.
Maintenance and care
151

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
with a screwdriver to release the
blade and pull the wiper blade
down 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).

4. Remove headlamp by taking the
pins out. Pull headlamp forward to
access headlamp connector.
5. Disconnect the electrical
connector from the bulb by pulling
the connector rearward.
6. Remove the bulb retaining ring
by rotating it counterclockwise
(when viewed from the rear) to
free it from the bulb socket, and
by sliding the ring off the plastic
base. Keep the ring because it will
be used again to retain the new
bulb.
7. Remove the old bulb from its
socket by gently pulling it straight
back out of the socket. Do not turn
the bulb while removing it.
To install the new bulb:
1. Insert the glass end of the bulb
into the socket. You may need to
turn the bulb left or right to line
up the grooves in the plastic base
with the tabs in the socket. When
the grooves are aligned, push the
bulb into the socket until the
plastic base contacts the rear of
the socket.

2. Slip the bulb retaining ring over
the plastic base until it contacts
the rear of the socket by rotating it
clockwise until you feel a ªstop.º
3. Push the electrical connector
into the rear of the plastic base
until it snaps, locking it into
position.
4. Turn the headlamps on and
make sure they work properly. If
the headlamp was correctly aligned
before you changed the bulb, you
should not need to align it again.
5. Carefully insert the headlamp
assembly into the vehicle making
sure the alignment pins are
inserted into the proper holes and
into the guides.
AIMING THE HEADLAMPS
Your vehicle is equipped with a
Vehicle Headlamp Aim Device
(VHAD) on each headlamp body.
Each headlamp may be properly
aimed in the horizontal direction
(left/right) and the vertical
position (up/down).
A non-zero bubble reading does
not necessarily indicate out-of-aim
headlamps. If your vehicle is not
positioned on a level surface, the
slope will be included in the level
indicator. Therefore, vertical
headlamp adjustment should be
performed only when beam
direction appears to be incorrect
or a level surface can not be
verified.
