[AndresFitz]

Audi A6 seat ventilation can be turned on or off at the air conditioning control panel for both the driver and front passenger seats, with both heating and ventilation functions featuring three adjustable levels indicated by the number of illuminated button lights. Audi A6L seat ventilation overview: Seats: The seat ventilation in Audi A6 is achieved by adding fans to the foam backing of the seat cushion and backrest. Principle: The fans draw in air and direct it into the ventilation layer, where the airflow then permeates upward through the heating pad to the surface of the seat cover (made of perforated leather). This allows passengers to use the ventilation function to dissipate sweat from the hips and back in hot weather, providing enhanced comfort.
