Ford Motor Company strongly recommends that
used lead-acid batteries be returned to an
authorized recycling facility for disposal.

Because your vehicle's engine is electronically
controlled by a computer, some control
conditions are maintained by power from the
battery. If you ever disconnect the battery or
install a new battery, you must allow the
computer to "relearn" its idle conditions before
your vehicle will drive properly. To let the
engine do this, put the gearshift in P (Park), turn
off all the accessories, and start the vehicle. Let
the engine idle for at least one minute. (Engine
must be warm in order to "learn.") Also, allow
approximately 10 miles (16 km) of stop and go
traffic for your vehicle's engine to completely
"relearn" its idle.

Wiper Blades

Check the windshield wiper blades at least twice
a year. Also check them whenever they seem
less effective than usual. Substances such as tree
sap and some hot wax treatments used by
commercial car washes reduce the effectiveness
of wiper blades.
If the blades do not wipe properly, clean both
the windshield and the wiper blades. Use
undiluted windshield washer solution or a mild
detergent. Rinse thoroughly with clear water. Do
