AIMING THE HEADLAMPS
The alignment of your headlamps should be checked by a qualified
service technician if:
²Oncoming motorists frequently signal you to deactivate your high
beams, and your high beams are not activated.
²The headlamps do not seem to provide enough light for clear night
vision.
²The headlamp beams are pointed substantially away from a slightly
down and to the right position.
CLEANING AND CARING FOR YOUR VEHICLE
Refer to the ªCustomer Assistance Guideº 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. If you have wax applied to the vehicle at a commercial car wash, it
is recommended that you clean the wiper blades and windshield as
described inCleaning the wiper blades and windshield.
After washing, apply the brakes several times to dry them.
Maintenance and care
227

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. Use cleaning fluid or
alcohol with a clean cloth to remove any bugs and tar before waxing
vehicle. Use tar remover to remove any tar spots.
Avoid getting wax on the windshield. If you have wax applied at a
commercial car wash, it is recommended that you clean the wiper blades
and windshield as described inCleaning the wiper blades and
windshield.
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.
Maintenance and care
228

²5.0L
²4.0L SOHC
²Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
Cleaning the wheels
Wash with the same detergent as the body of your vehicle. Do not use
acid-based or alcohol-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.
Maintenance and care
229

Underbody
Flush the complete underside of vehicle frequently. Keep body drain
holes unplugged. Inspect for road damage.
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 and windshield
If the wiper blades do not wipe properly, clean the wiper blade rubber
element with undiluted windshield washer solution or a mild detergent.
To avoid damaging the blades, do not use fuel, kerosene, paint thinner or
other solvents.
If the wiper still does not wipe properly, this could be caused by
substances on the windshield such as tree sap and some hot wax
treatments used by commercial car washes. Clean the outside of the
windshield with a non-abrasive cleanser such as the non-abrasive
Bon-Amitpowder. Rinse thoroughly with clean water.Do notuse
abrasive cleansers on glass as they may cause scratches. The windshield
is clean if beads do not form when you rinse it with water. The
windshield and wiper blades should be cleaned on a regular basis, and
blades or rubber elements replaced when worn.
Cleaning seats equipped with side air bags
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. Do not saturate the seat cover with upholstery cleaner.
Do not use chemical solvents or strong detergents when cleaning
the seat mounted side air bag. Such products could contaminate
the side air bag system and affect performance of the side air bag in a
collision.
Maintenance and care
230

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 overhead console
Clean with a damp cloth, then wipe dry with a dry cloth.
Avoid cleaner or polish that increases the gloss of the console. 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. Do not use household or glass cleaners.
These agents can stain and discolor the fabric. Use a mild soap and
water solution if necessary.
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.
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 leather seats (if equipped)
To clean, simply use a soft cloth dampened with water and a mild soap.
Wipe the leather again with a damp cloth to remove soap residue. Dry
with a soft cloth. For tougher soiling concerns, Ford recommends using
the leather cleaning kit F8AJ-19G253±AA, which is available from your
Ford Dealer. This mild cleaner and special pad, cleans the leather and
maintains its natural beauty. Follow the instructions on the cleaner label.
Regular cleaning of your leather upholstery helps maintain its resiliency
and color.
Do not use household cleaning products, alcohol solutions,
solvents or cleaners intended for rubber, vinyl or plastics.
Maintenance and care
231

Woodtone trim
Wipe stains with a soft cloth and a multi-purpose cleaning solution.
Inside windows
Use glass cleaner for the inside windows if they become fogged.
Cleaning mirrors
Do not clean your mirrors with a dry cloth or abrasive materials. Use a
soft cloth and mild detergent and water. Be careful when removing ice
from outside mirrors because you may damage the reflective surface.
Maintenance and care
