WAXING
•Wash the vehicle first.
•Use a quality wax that does not contain abrasives.
•Do not allow paint sealant to come in contact with any non-body
(low-gloss black) colored trim, such as grained door handles, roof
racks, bumpers, side moldings, mirror housings or the windshield cowl
area. The paint sealant will gray or stain the parts over time.
REPAIRING MINOR PAINT DAMAGE
Your authorized dealer has touch-up paint to match your vehicle’s color.
Take your color code (printed on a sticker in the driver’s door jamb) to
your authorized dealer to make sure you get the correct color.
•Remove particles, such as bird droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout, before repairing paint chips.
•Always read the instructions before using the products.
CLEANING THE 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 on all parts that
require cleaning and pressure rinse clean. In Canada, use Motorcraft
Engine Shampoo.
•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 battery, power distribution box, and air filter assembly to
prevent water damage when cleaning the engine.
