alternator Mercury Mountaineer 2007 Owner's Manuals

The ignition must be in the 3 (ON) position to operate the rear window
defroster.
The defroster turns off automatically after 10 minutes or when the
ignition is turned to the 1 (OFF/LOCK) or 2 (ACC) position. To manually
turn off the defroster before 10 minutes have passed, push the control
again.
Heated Windshield Control (if equipped)
The heated windshield control is located on the instrument panel just
under the climate controls.
To activate the heated windshield, the engine must be running while the
heated windshield control is pushed. Once activated, a small light on the
button will illuminate.
Note:During initial start-up, the windshield may have a shimmering
appearance. This is normal operation and will only last for approximately
1 minute.
The heated windshield will turn off automatically after:
•a period of up to 8 minutes, when
the outside air temperature is
below 40 °F,
•a period of up to 4 minutes when
the outside air temperature is
40 °F or above, or
•when the engine is turned off.
To manually turn off the heated windshield before the specified time has
passed, push the control switch again.
Note:Pushing the heated windshield button to activate the system will
increase engine idle speed when the engine is warm and is already at or
near its warmed up idle rpm. No increase in engine rpm will be noticed if
the engine is cold and running at higher rpms associated with cold starts.
This rpm increase is required to provide adequate power from the
alternator to the heated windshield and maintain power to the other
electrical functions in the vehicle.
