What is the method to defog the windows of an Audi A4?

[OGeorge]

Audi A4 window defogging method is as follows: first turn on the car air conditioner and adjust it to the hot air position; then start the external circulation, aim the air outlet at the front windshield and blow hot air directly to allow outside air to enter the car; finally press the car window defogging button. Common car defogging methods are as follows: 1. Warm air defogging: In winter, use warm air to raise the temperature of the front windshield, reducing the temperature difference between the inner and outer surfaces of the glass, which can promptly prevent excessive fogging on the front windshield. 2. Cold air defogging: Use the air conditioning dehumidification function to reduce air humidity, which can also remove fog. 3. Use defogging spray: Spray the defogging agent on the inner side of the front windshield and windows, then wipe evenly with a cloth, and let it dry in the sun.
