not be displayed in the display window.) Recirculation and A/C
override controls cannot be selected. For added customer comfort, the
system will allow some airflow through the floor ducts in this mode.
Turning the EATC off
OFF — Outside air is shut out. The fan, heating, and air conditioning will
not operate. The outside temperature will still display when selected
with the ignition in the ON position.
Displaying outside temperature
Press EXT TEMP to display the
outside air temperature. It will be
displayed until EXT TEMP is
pressed again.
If the temperature or fan speed is adjusted or if AUTO or modes
are selected while the outside temperature is being displayed, the vehicle
interior temperature will be displayed for four seconds. After four
seconds have passed, the outside temperature will return to the display
window.
If the outside temperature is displayed while the EATC system is in the
OFF mode and then is turned on, 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 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 location.
