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 AC button or the TEMP/AUTO knob to turn the system on and then select the proper mode to direct airflow. 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. When the air conditioner is on, you may sometimes notice slight changes in your vehicle's engine speed and power. This is normal because the system is designed to cycle the compressor on and off to maintain the desired temperature. Heating Press the MODE switch to select the heater mode. 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. Defogging and Defrosting Use defrost to remove fog or ice from the windshield quickly in extremely humid or cold conditions. Press the MODE switch. If you select defrost mode, adjust the fan speed by pressing the fan switch up or down. If you select defrost mode from AUTO, the system will control the fan speed. The temperature also needs to be adjusted by turning the TEMP/AUTO knob. Recirculation is not available in the defrost or defog modes. 3-7
