System Operation: Auto

When AUTO is selected:

• the HVAC system operates in a manner to achieve and maintain the temperature set by the operator.
• the driver and passenger side temperature doors are automatically controlled by the FCIM based on the temperature setting.
• the A/C compressor is automatically controlled by the PCM from information sent by the FCIM, based on the temperature setting. The A/C compressor operates as long as the outside temperature is above approximately 0°C (32°F).
• the blower motor speed is automatically controlled through the blower motor speed control that receives a PWM signal from the FCIM based on the temperature setting, but can be manually overridden.
• the FCIM controls the air inlet door to recirculate, partially recirculate or open to the fresh air position depending on the in-car temperature and humidity sensor inputs.
