Design (Described on switch on driver side, left)
The left front HS [SIH] switch is designed as a push-push switch. This switch changes the respective switching status depending on the number of actuations.

The left front HS [SIH] switch and right front HS [SIH] switch are located on the upper control panel control unit (N72/1).

Heated seat function
An actuation of the left front HS [SIH] switch or the right front HS [SIH] switch is read in by the upper control panel control unit and sent over the interior CAN to the front SAM control unit (N10). If the heated seat is switched on, then red LED indicator lamps indicate the corresponding actuation in the left front HS [SIH] switch or the right front HS [SIH] switch.
