Servicing Your Contour
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.
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.
Windshield Washer Fluid and Wipers
Washer Fluid
Check the level of the windshield washer fluid every time you
stop for fuel. The reservoir for washer fluid is located on the
passenger's side of the engine compartment. Visual inspection
can determine if the washer fluid is adequate. Do not operate
the washer when the reservoir is empty.
