FORD 2003 Expedition v.1 - Manual (Page 74)

Temperature conversion
Press the Fahrenheit/Celsius (F/C)
control to switch between
Fahrenheit and Celsius temperature
on the EATC display. The
temperature in Celsius will be
displayed in half-degree increments.
The English/Metric (E/M) control on
the message center (if equipped)
and the trip computer will not
change the temperature display.
Displaying outside temperature
Press EXT to display the outside air
temperature. It will be displayed
until EXT is pressed again.
If the interior temperature or fan speed are adjusted or a manual
override is selected while the outside temperature is being displayed, the
new temperature, fan speed, or override control will appear in the
display window for four seconds and the outside temperature will return
to the display window.
The outside temperature reading is most accurate when the vehicle is
moving. Higher readings may be displayed when the vehicle is not
moving. Due to locations, the outside temperature readings from the
vehicle may not agree with those obtained from radio station broadcasts.
