Electronic Solar Sensor 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. Press the AUTO button or the TEMP knob to turn the system on. The system will cool and dehumidify the air inside the vehicle. Also while in the AUTO mode, the system will use recirculation as necessary to cool the air. You may also need to adjust the interior temperature and the fan speed as needed. Heating Press the MODE button to select heater. Adjust the interior temperature to a comfortable level and if the fan speed needs adjusting, press the up or down arrow. Outside air will be brought in and sent through the floor, air conditioning or bi-level outlets (depending on the condition). The heater works best if you keep your windows closed while using it. The sensor monitors the sun's solar radiation and is located on top of the instrument panel near the windshield. The ECC panel uses this information to automatically make the necessary temperature and airflow adjustments to maintain your comfort. 3-6
