Replacing headlamp bulbs
To remove the headlamp bulb:
1. Make sure headlamp switch is in the off position, then open the hood.
2. Disconnect the electrical
connector from the bulb by
depressing the retainer clip and
pulling rearward.
3. Remove the bulb by rotating it
counterclockwise and pulling it
straight out.
WARNING: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.
Install the new bulb in reverse order.
Replacing HID headlamp bulbs (if equipped)
The headlamps on your vehicle use a “high intensity discharge” source.
These lamps operate at a high voltage. When the bulb is burned out, the
bulb and starter capsule assembly must be replaced by your authorized
dealer.

Follow all instructions provided by the manufacturer of the booster seat.
WARNING:Never place, or allow a child to place, the shoulder
belt under a child’s arm or behind the back because it reduces
the protection for the upper part of the body and may increase the risk
of injury or death in a collision.
Child restraint and safety belt maintenance
Inspect the vehicle safety belts and child safety seat systems periodically
to make sure they work properly and are not damaged. Inspect the
vehicle and child seat safety belts to make sure there are no nicks, tears
or cuts. Replace if necessary. All vehicle safety belt assemblies, including
retractors, buckles, front safety belt buckle assemblies, buckle support
assemblies (slide bar-if equipped), shoulder belt height adjusters (if
equipped), shoulder belt guide on seatback (if equipped), child safety
seat LATCH and tether anchors, and attaching hardware, should be
inspected after a collision. Refer to the child restraint manufacturer’s
instructions for additional inspection and maintenance information
specific to the child restraint. Ford Motor Company recommends that all
safety belt assemblies in use in vehicles involved in a collision be
replaced. However, if the collision was minor and an authorized dealer
finds that the belts do not show damage and continue to operate
properly, they do not need to be replaced. Safety belt assemblies not in
use during a collision should also be inspected and replaced if either
damage or improper operation is noted.
For proper care of soiled safety belts, refer toInteriorin theCleaning
chapter.
WARNING:Failure to inspect and if necessary replace the
safety belt assembly or child restraint system under the above
conditions could result in severe personal injuries in the event of a
collision.

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.
Do not probe the contacts for the fuses and relays in the power
distribution box as damage will occur, causing improper, or loss
of, electrical functionality.
WARNING:Always disconnect the battery before servicing high
current fuses.
WARNING:To reduce risk of electrical shock, always replace
the cover to the Power Distribution Box before reconnecting the
battery or refilling fluid reservoirs.

ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
•Spray MotorcraftEngine Shampoo and Degreaser (ZC-20) on all
parts that require cleaning and pressure rinse clean. In Canada, use
MotorcraftEngine Shampoo (CXC-66-A).
•Never wash or rinse the engine while it is hot or running; water in the
running engine may cause internal damage.
•Never wash or rinse any ignition coil, spark plug wire or spark plug
well, or the area in and around these locations.
•Cover the highlighted areas to prevent water damage when cleaning
the engine.

For cloth tops wash with a high quality convertible top
cleaner/protectant.
•Do not use stiff bristle brushes or abrasive materials or cleaners.
•Hot waxes applied by commercial car washes can affect the
cleanability of vinyl material.
•Using high water pressure or wand-type car washes against the
convertible top and windows may cause water leaks and possible seal
damage.
INSTRUMENT PANEL/INTERIOR TRIM AND CLUSTER LENS
Clean the instrument panel, interior trim areas and cluster lens with a
clean, damp, white cotton cloth, then use a clean and dry white cotton
cloth to dry these areas.
•Avoid cleaners or polishes that increase the gloss of the upper portion
of the instrument panel. The dull finish in this area helps protect the
driver from undesirable windshield reflection.
•Be certain to wash or wipe your hands clean if you have been in
contact with certain products such as insect repellent and suntan
lotion in order to avoid possible damage to the interior painted
surfaces.
•Do not use household or glass cleaners as these may damage the
finish of the instrument panel, interior trim and cluster lens.
•Do not allow air fresheners and hand sanitizers to spill on interior
surfaces. If a spill occurs,wipe off immediately.Damage may not be
covered by your warranty.
WARNING:Do not use chemical solvents or strong detergents
when cleaning the steering wheel or instrument panel to avoid
contamination of the airbag system.
If a staining liquid like coffee/juice has been spilled on the instrument
panel or on interior trim surfaces, clean as follows:
1. Wipe up spilled liquid using a clean, white, cotton cloth.
2. Wipe the surface with a damp, clean, white cotton cloth. For more
thorough cleaning, use a mild soap and water solution. If the spot cannot
be completely cleaned by this method, the area may be cleaned using a
commercially available cleaning product designed for automotive
interiors.
3. If necessary, apply more soap and water solution or cleaning product
to a clean, white, cotton cloth and press the cloth onto the soiled
area–allow this to set at room temperature for 30 minutes.

4. Remove the soaked cloth, and if it is not soiled badly, use this cloth to
clean the area by using a rubbing motion for 60 seconds.
5. Following this, wipe area dry with a clean, white, cotton cloth.
INTERIOR
For fabric, carpets, cloth seats, safety belts and seats equipped with side
airbags:
•Remove dust and loose dirt with a vacuum cleaner.
•Remove light stains and soil with MotorcraftProfessional Strength
Carpet & Upholstery Cleaner (ZC-54).
•If grease or tar is present on the material, spot-clean the area first
with MotorcraftSpot and Stain Remover (ZC-14). In Canada, use
MotorcraftMulti-Purpose Cleaner (CXC-101).
•If a ring forms on the fabric after spot cleaning, clean the entire area
immediately (but do not oversaturate) or the ring will set.
•Do not use household cleaning products or glass cleaners, which can
stain and discolor the fabric and affect the flame retardant abilities of
the seat materials.
WARNING:Do not use cleaning solvents, bleach or dye on the
vehicle’s safety belts, as these actions may weaken the belt
webbing.
WARNING:On vehicles equipped with seat-mounted airbags, do
not use chemical solvents or strong detergents. Such products
could contaminate the side-airbag system and affect performance of
the side airbag in a collision.
LEATHER SEATS (IF EQUIPPED)
•Remove dust and loose dirt with a vacuum cleaner.
•Clean spills and stains as quickly as possible.
•For routine cleaning, wipe the surface with a soft, damp cloth. For
more thorough cleaning, wipe the surface with a mild soap and water
solution. In Canada, use MotorcraftVinyl Cleaner (CXC-93). Dry the
area with a soft cloth.
•If the leather cannot be completely cleaned using a mild soap and
water solution, the leather may be cleaned using a commercially
available leather cleaning product designed for automotive interiors.
