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
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.
