Front active seat ventilation
The seat cushion and backrest surfaces are cooled by means of integrated fans.
The ventilation rapidly cools the seat, e.g., if the vehicle interior is overheated or for continuous cooling at high temperatures.

level.
The highest level is active when three LEDs are lit.
After a short time, the system automatically moves down one level in order to prevent excessive cooling.
