3. Adjust the temperature to a comfortable setting between 68°F (21°C) and 78°F (26°C). Choosing the coldest or warmest temperature setting will not cause the system to heat or cool any faster. In cold weather, the system will start at reduced fan speeds to avoid blowing cold air into your vehicle until warmer air is available. The system will start out blowing air at the floor but may change modes automatically as the vehicle warms up to maintain the chosen temperature setting. The length of time needed to warm the interior will depend on the outside temperature and temperature of the vehicle. 4. Wait 20 to 30 minutes for the system to stabilize in order for the system to regulate automatically. Then adjust the temperature as necessary to find your comfort setting. Do not cover the solar sensor located in the center of the instrument panel near the windshield. For more information on the solar sensor, see "Sensors" later in this section. After the vehicle is started, the display will show the interior temperature settings and the outside temperature. If the AUTO position is selected on the fan or mode control, the system will automatically control the air conditioning compressor. The A/C compressor will run automatically even at cool outside temperatures in order to dehumidify the air. The A/C indicator light will be lit when the system is operating automatically, even at near freezing outside temperatures. Press the A/C button on the fan control to turn off the A/C. For improved window clearing performance in defog or defrost modes, the A/C compressor will run automatically. h (AUTO RECIRCULATION): If the AUTO position is selected on either the fan or mode control, the system will automatically control the air inlet to supply fresh outside air or recirculate the interior air to cool the car faster. The indicator light on the recirculation button will light whenever the system switches to recirculation. You may force outside air by pressing the recirculation button when the light is lit. For vehicles without rear climate controls, press the outside air button to force outside air. The next time AUTO fan or mode is selected, the air inlet will reset back to AUTO operation. 205
