(Recirculation): Press this button to limit the amount of outside air entering your vehicle. This is helpful when you are trying to cool the air quickly or limit odors entering your vehicle. Press this button again to turn off the recirculation feature. If you notice the windows fogging, press the recirculation button to exit the recirculation mode. Recirculation is not available in the defrost mode. A/C (Air Conditioning): Press this button to turn the air conditioning compressor on and off. The system will cool and dehumidify the air inside the vehicle. When the compressor is off, A/C OFF appears on the climate control panel display. Press the button again and the compressor will turn back on. The A/C OFF feature is not available in the defrost mode. AUTO (Automatic): The AUTO button will turn on the system and automatically adjust the fan speed, air delivery mode and temperature to your previously programmed settings. When the system is set for automatic operation, sensors will control the air delivery mode. Air will come from the floor ducts, the instrument panel or windshield outlets. The fan speed will vary as the system maintains the selected temperature setting. To find your comfort zone, start with the 75_F (24_C) setting and allow about 30 minutes for the system to regulate. Turn the TEMP knob to adjust the temperature if necessary. If you choose 60_F (16_C), the system will remain at that maximum cooling setting and will not regulate fan speed. If you choose 90_F (32_C), the system will remain at that maximum heating setting and will not regulate fan speed. Choosing either maximum setting will not cause the system to heat or cool any faster. With the automatic setting, the air conditioning compressor cycles on and off when needed to cool the air. In cold weather, when the system senses the need for heat, the airflow will be directed out the floor ducts. As the interior temperature approaches a desired setting, the fan speed will decrease. To maintain interior comfort, the airflow may move to the instrument panel air outlets and floor ducts. On bright sunny days in cold weather, the airflow may come out of the instrument panel outlets to maintain comfort and prevent stuffiness. 3-4
