Sun and temperature sensors automatically adjust the air temperature, the airflow direction and the fan speed to maintain your temperature setting. The system may supply cooler air to the side of the vehicle toward the sun. Be careful not to put anything over the sensor on top of the dash. The display will show fan speed, temperature 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. To find your preferred temperature setting, start with the system in AUTO mode and the TEMP button adjusted to 75_F (24_C), give the vehicle about 20 minutes to stabilize, and adjust your temperature setting if necessary, by using the TEMP button. The display will show the temperature setting for a few seconds and then it will display the outside temperature. If you want to see your current automatic fan speed, airflow direction and temperature setting, press the AUTO button. In cold weather, the system will delay turning on the fan, to avoid blowing cold air. During this delay the system will be in FRONT defrost mode and the light in the button will come on and stay on as long as the display is showing the current mode, set TEMP and FAN speed. This light will go off when the display returns to the outside temperature. The length of the delay depends on the engine coolant temperature and the outside temperature. Pushing the FAN, AIR FLOW or FRONT buttons will override this delay, turn off the AUTO setting and return the system to manual operation. Personal Choice Comfort Controls (If Equipped) This feature enables up to two drivers to store and recall comfort control settings for the temperature, fan speed and the direction of the airflow. The memory buttons (1 or 2) for this feature are located on the driver's door panel and correspond to the numbers (1 or 2) found on the back of each keyless entry transmitter. To recall comfort settings, press the unlock button on the remote keyless entry transmitter and put the ignition in ACCESSORY or RUN. The climate control setting last chosen by the identified driver (1 or 2) will be recalled. 3-7
