Dual Automatic Comfortemp
Climate Control (If Equipped)
If your vehicle has the Dual Automatic Comfortemp
Climate Control option, the following information tells
you how it works.
You will hear a beep each time a button is pushed and a
light on the button will indicate which function is active.
The lights are on all buttons except TEMP, FAN and
AIR FLOW. The display will show fan speed, comfort
level setting and airflow direction for a few seconds
whenever AUTO is selected, and then it will display the
outside temperature. The outside temperature reading is
most accurate when the vehicle is moving. During stops,
the display shows the previous temperature for best
accuracy and system control.
