Where is the defogging button on the Audi A8?

[JulietteRose]

A fan-shaped button with three heating wire symbols inside is the one. Here are the specific details: 1. Cause of fogging: In cold environments, when starting to drive, the transparent water vapor exhaled by people meets the cold windshield, turning back into liquid and becoming opaque, which affects driving visibility. 2. Fuel gauge: Indicated by the English letters FUEL. The pointer pointing to F means the fuel tank is full. Pointing to E means the fuel tank is empty. 3. Water temperature gauge: Indicated by the English letters TEMP. The pointer pointing to H means the water temperature is too high. Pointing to C means the water temperature is too low. Pointing to the area between the two letters means the water temperature is normal. 4. Oil pressure gauge: Indicated by the English letters OIL. The pointer in the red zone means the oil pressure is too low. Pointing to the green zone means the oil pressure is normal.
