About Your Battery
Your vehicle may have a Motorcraft
maintenance-free battery. When the original
equipment battery is replaced under warranty, it
may be replaced by a Motorcraft
Low-Maintenance Battery.
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 begin this
process, put the gearshift in P (Park), set the
parking brake, turn off all the accessories, and
start the vehicle. Bring the engine to normal
operating temperature. Allow the engine to idle
for one minute in N (Neutral) and one minute in
Drive or Overdrive. Perform the previous
procedure with the air conditioning on and off
(conditions permitting). The relearning process
will complete automatically as you drive the
vehicle.
If you do not let the engine relearn its idle, the
idle quality of your vehicle may be adversely
affected until the idle is relearned. Your vehicle
will eventually relearn its idle while you drive
it, but it takes much longer than if you use the
previous procedure.
