Function
The driver seat or front passenger seat can be heated in three heating stages using the left front seat heated cushions (R13/1) and the left front backrest heated cushions (R13/2) or the right front seat heated cushions (R13/3) and the right front backrest heated cushions (R13/4) integrated in the driver and front passenger seat.

The heated seats HS [SIH] are actuated via the left front HS [SIH] switch (N72/1s10) and the right front HS [SIH] switch (N72/1s11), which are read in by the upper control panel control unit (N72/1

The upper control panel control unit (N72/1) actuates the heated cushions (R13/1, R13/2, R13/3, and R13/4) in the seat cushions and backrests.

The different heat outputs are implemented via pulsed actuation of the voltage in the heated cushions (R13/1, R13/2, R13/3, and R13/4).

The function conditions are indicated via three red LEDs in the left front HS [SIH] switch (N72/1s10) or in the right front HS [SIH] switch (N72/1s11).

The following control units play a leading role:
^ Upper control panel control module (N72/1)
^ EIS [EZS] control unit (N73)
^ AAC [KLA] control and operating unit (N22) (without code (581b) comfort automatic air conditioning)
