Dual Automatic ComforTemp
Climate Control
Your vehicle has the Dual Automatic ComforTemp
Climate Control system. The following information tells
you how it works.
You will hear a beep each time a button is pushed and a
small light on the button will indicate which buttons are
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.

If the display is flashing after the climate control system
is started, there is a problem with the system and you
should see your dealer for service.
Sun and temperature sensors automatically adjust the air
temperature, the airflow direction and the fan speed to
maintain your comfort setting. The system may supply
cooler air to the side toward the sun. Be careful not to
put anything over the sensors on top of the dash.
