Please consult your ``Warranty Guide'' for complete emission warranty
information.
Readiness for inspection/maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostic (OBD-II) system. If your ``check engine/service
engine soon'' light is on, reference the applicable light description in the
Warning Lights and Chimessection of your owners guide. Your vehicle
may not pass the I/M test with the ``check engine/service engine soon''
light on.
If the vehicle's powertrain system or its battery has just been serviced,
the OBD-II system is reset to a ``not ready for I/M test'' condition. To
ready the OBD-II system for I/M testing, a minimum of 30 minutes of city
and highway driving is necessary as described below:
²First, at least 10 minutes of driving on an expressway or highway.
²Next, at least 20 minutes driving in stop and go, city type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.

²back-up lamps
Do not remove lamp bulbs unless they can be replaced immediately with
new ones. If a bulb is removed for an extended period of time,
contaminants may enter the lamp housings and affect lamp performance.
Replacing headlamp bulbs
Handle a halogen headlamp bulb carefully and keep out of
children's reach. Grasp the bulb only by its plastic base and do
not touch the glass. The oil from your hand could cause the bulb to
break the next time the headlamps are operated.
If the bulb is accidentally touched, it should be cleaned with rubbing
alcohol before being used.
To remove the headlamp bulb:
1. Make sure headlamp switch is in OFF position, then open the hood. If
you are replacing the driver side headlamp, unclip the electronic module
on the right side of the battery and move it out of the way.
2. Locate the headlamp bulb through the hole in the upper radiator
support assembly.
3. Disconnect the electrical
connector from the bulb by pulling
the connector rearward.
4. Remove the bulb retaining ring by
rotating it counterclockwise (when
viewed from the rear) about an
eighth of a turn 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.
Maintenance and care
187

5. 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. With the flat side of the bulb's
plastic base facing upward, 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 ``stop''.
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.

AIMING THE HEADLAMPS
Your vehicle is equipped with a
Vehicle Headlamp Aim Device
(VHAD) on each headlamp. Each
headlamp may be properly aimed in
the vertical (up/down) and the
horizontal (left/right) directions
using your VHAD system. The
headlamps on your vehicle are
properly aimed at the assembly
plant, and vertical and horizontal
indicators of the VHAD system are
calibrated.
A bubble (vertical indicator) that is
not centered between the two red
lines 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 vertical indication. Therefore, vertical and horizontal headlamp
adjustment should be performed only when the beam direction appears
to be incorrect.
You will need one 4 mm wrench or socket with ratchet to make the
adjustments.
The following procedure assumes that the factory set horizontal indicator
reference has not changed and the vehicle's front structure is in its
factory alignment condition. If the vehicle has been in an accident
requiring the front end of the vehicle to be repaired, the horizontal
indicator should be recalibrated by the servicing facility according to
instructions in the vehicle's Workshop Manual.

Horizontal aim adjustment
1. With the hood open, locate the
horizontal indicator and adjusting
screw. They are located below the
viewing hole at the rear of the
headlamp assembly.
2. Use a 4mm wrench or socket to
turn the horizontal adjusting screw
until the ``0'' mark on the yellow dial
lines up with the reference mark on
the marker (as shown) when viewed
directly from above.
Vertical aim adjustment
1. Park the vehicle on a level
surface.
2. With the hood open, locate the
bubble level and vertical adjustment
screw. The adjustment screw is
located on the outboard side of the
headlamp.

3. The ``UP'' and ``DN'' on the bubble
indicate the directional change (up
or down) of the vertical aim.
4.Usea4mmwrench or socket to
turn the vertical adjusting screw
clockwise or counterclockwise until
the bubble is centered over the ``0''
mark.
Repeat the above process to the other headlamp, if necessary.
CLEANING AND CARING FOR YOUR VEHICLE
Refer to the ``Customer Assistance Guide'' for a list of Ford-approved
cleaners, polishes and waxes.
Washing your vehicle
Wash your vehicle regularly with
cold or lukewarm water. Never use
strong detergents or soap. If your
vehicle is particularly dirty, use a
quality car wash detergent. Always
use a clean sponge, washing glove
or similar device and plenty of water
for best results. To avoid spots,
avoid washing when the hood is still
warm, immediately after or during
exposure to strong sunlight.
During winter months, it is especially important to wash the vehicle on a
regular basis. Large quantities of dirt and road salt are difficult to
remove and also cause damage to the vehicle. Remove any exterior
accessories, such as antennas, before entering a car wash.
After washing, apply the brakes several times to dry them.

Waxing your vehicle
Wax when water stops beading on the surface. This could be every three
or four months, depending on operating conditions.
Use only carnauba or synthetic-based waxes. Remove any bugs and tar
before waxing vehicle. Use cleaning fluid or alcohol with a clean cloth to
remove. Use tar remover to remove any tar spots.
Repairing paint chips
Minor scratches or paint damage from road debris may be repaired with
touch-up paint, repair foil or aerosol paint spray from the Ford accessory
line. Observe the application instructions on the products.
Remove particles such as bird droppings, tree sap, insect remains, tar
spots, road salt and industrial fallout immediately.
Cleaning the engine
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
²Take care when using a power washer to clean the engine. The high
pressure fluid could penetrate the sealed parts and cause damage.
²Do not spray with cold water to avoid cracking the engine block or
other engine components.
²Cover the highlighted areas to prevent water damage when cleaning
the engine.

²Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
Maintenance and care
193

Cleaning the wheels
Wash with the same detergent as the body of your vehicle. Do not use
acid-based wheel cleaners, steel wool, fuel or strong detergents. Never
use abrasives that will damage the finish of special wheel surfaces. Use a
tar remover to remove grease and tar.
Cleaning plastic exterior parts
Use vinyl cleaner for routine cleaning. Clean with a tar remover if
necessary. Do not clean plastic parts with thinners, solvents or
petroleum-based cleaners.
Cleaning the exterior lamps
Wash with the same detergent as the exterior of your vehicle. Use glass
cleaner or tar remover if necessary.
To avoid scratching the lamps, do not use a dry paper towel, chemical
solvents or abrasive cleaners.
Cleaning the wiper blades
If the wiper blades do not wipe properly, clean the windshield and wiper
blades with 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.
Cleaning the instrument panel
Clean with a damp cloth, then dry with a dry cloth.
Avoid cleaner or polish that increases the gloss of the upper portion of
the instrument panel. The dull finish in this area helps protect the driver
from undesirable windshield reflection.
Cleaning the interior fabric
Remove dust and loose dirt with a whisk broom or a vacuum cleaner.
Remove fresh spots immediately. Follow the directions that come with
the cleaner.
Cleaning and maintaining the safety belts
Clean the safety belts with a mild soap solution recommended for
cleaning upholstery or carpets. Do not bleach or dye the belts, because
these actions may weaken the belt webbing.
Maintenance and care
194

Check the safety belt system periodically to make sure there are no
nicks, wear or cuts. If your vehicle has been involved in an accident,
refer to theSafety belt maintenancesection in theSeating and safety
restraintschapter.
Cleaning the built-in child seat (if equipped)
Clean with mild soap and water. Do not use household cleaning products
because they may weaken the safety belt webbing or damage the vinyl
parts of the seat.
The child seat liner is removable and may be machine-washed and air
dried.
Underbody
Flush the complete underside of vehicle frequently. Keep body drain
holes unplugged. Inspect for road damage.
Cleaning leather seats (if equipped)
For routine cleaning, wipe the surface with a soft, damp cloth. For more
thorough cleaning, wipe the surface with a mild soap.
If the leather cannot be completely cleaned using a mild soap and water
solution, the leather may be cleaned using a commercially available
cleaning product ``Tanners Preserve Leather Cleaner'' and a 3M ``Type T''
scrubbing pad by using the following steps;
The type of scrubbing pad is very critical because the common 3M
``Scotch Brite'' green pad is too aggressive and will damage the
leather surface
²Spray a small amount of the leather cleaner on the pad and rub the
area to be cleaned with the pad using a circular motion. Only clean 1/4
of the area at a time. For heavily soiled areas, spray the cleaner
directly onto the leather (two squirts should be adequate) and rub
with the pad. Repeat if necessary.
²Use a soft, damp cloth to remove the loosened dirt and foam.
²Dry with a soft cloth.
Do not use household cleaners, glass cleaner, alcohol solutions or
cleaner intended for vinyl, rubber or plastics. These products can
damage the leather.
In some instances, color or dye transfer can occur when wet
clothing (wool, denim, leathers or other non-colorfast garments)
