[LaAliyah]

The instructions for using the buttons on the air conditioning system of the new Audi A4L are as follows: Defogging: There are two buttons for defogging: one for the front windshield and one for the rear windshield. Press the corresponding button to activate the defogging function for the windshield. Heating: Simply increase the temperature to activate the heating function. Additionally, turn off the A/C button to save energy, as the air conditioning compressor is only used for cooling. Heating is achieved through the engine's coolant and the heat from the windshield heating elements. AUTO: Press the AUTO button, and the air conditioning system will automatically maintain a stable temperature inside the car without manual adjustment. This includes determining whether to cool or heat and adjusting the fan speed intelligently based on sensor readings. Internal/External Circulation: Internal circulation involves heating or cooling the air inside the car and recirculating it, while external circulation allows outside air to enter the car. Generally, use internal circulation in heavy traffic or when the outside air quality is poor. On highways, switch to external circulation periodically to ensure fresh air and prevent health issues due to stale air.
