AUTO (Automatic Climate Control): Press the AUTO button when you want the system to automatically maintain a set temperature. When the system is set for automatic operation, air will come from the floor ducts, instrument panel outlets or windshield outlets depending on the temperature inside the vehicle, the outside temperature and the sun load. 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 of the vehicle toward the sun. Be careful not to put anything over the sensors on top of the dash. To find your preferred temperature setting, start with the system in AUTO mode and the temperature set at 75_F (24_C). Give the vehicle about 20 minutes to stabilize, and adjust your the temperature setting, if necessary, using the TEMP button. The display will show the selected temperature, fan speed and airflow direction for a few seconds, and then it will display the outside temperature. If you choose a temperature setting of 60_F (15_C), the system will remain at the maximum cooling setting and fan speed. If you choose a temperature setting of 90_F (33_C), the system will remain at the maximum heat setting and fan speed. Choosing either maximum setting will not cause the system to heat or cool any faster. In cold weather, the system will delay turning the fan on high, to avoid blowing cold air into the vehicle. The length of the delay depends on the engine coolant temperature and the outside temperature. Pressing the FAN, AIR FLOW or FRONT buttons will override this delay, turn off the AUTO setting and change the fan speed. Air Conditioning On hot days, open the windows long enough to let hot inside air escape. This reduces the time it takes for your vehicle to cool down. Then keep your windows closed for the air conditioner to work its best. On very hot days, the automatic system will enter the recirculation mode and the temperature door will be positioned at the full cold position for maximum cooling for as long as necessary to reach the set temperature. You can choose the extreme temperature setting of 60_F (15_C), but the system will not cool any faster. 3-4
