Applying too much pressure on the ends when lifting a
battery could cause acid to spill. Lift the battery with a
carrier or with your hands on the opposite corners.

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

Disconnecting the Battery
Because your vehicle 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 begin this
process, put the gearshift in P (Park) (automatic transaxle) or
Neutral (manual transaxle), set the emergency brake, turn off all
the accessories, and start the vehicle. Bring the engine to normal
operating temperature. Allow the manual transaxle to idle for
one minute in Neutral. Allow the automatic transaxle engine to
idle for one minute in N (Neutral) and one minute in D (Drive).
Perform the previous procedure with the air conditioning (if
equipped) on and off (conditions permitting). The relearning
process will complete automatically as you drive the vehicle.
