Mercury 1999 Automobile User Manual


 
F- DEF -Distributes outside air through the
windshield defroster ducts. It can be used to clear
ice or fog from the windshield. If the outside air
temperature is about 10°C (50°F) or higher, the
air conditioner will automatically dehumidify the
air to prevent fogging.
OFF-Outside air is shut out and the fan will not
operate. For short periods of time only, use this
mode to prevent undesirable odors from entering
the vehicle.
Displaying outside temperature
Press OUTSIDE TEMP
to display the outside
air temperature. It will
be displayed until
OUTSIDE TEMP is
pressed again or until
any other control is
pressed. When the
EATC system is off and OUTSIDE TEMP is pressed,
the outside temperature will only be displayed for
four seconds.
The outside temperature reading is most accurate
when the vehicle is moving. Higher readings may be
obtained when the vehicle is not moving. The
readings that you get may not agree with
temperatures given on the radio due to differences
in vehicle and station locations.
Operating tips
In humid weather, select F-DEF before
driving. This will prevent your windshield from
fogging. After a few minutes, select any desired
position.
To prevent humidity buildup inside the vehicle,
don’t drive with the climate control system in the
OFF position.
Don’t put objects under the front seat that will
interfere with the airflow to the back seats.
