Function with code (873) heated seats for left and right front seats
The heated seats HS [SIH] have two heating stages.
By pushing the left front HS [SIH]/seat ventilation switch (N72/1s28) or the right front HS [SIH]/seat ventilation switch (N72/1s29) down, heating stage 2 of the heated seats HS [SIH] is activated (both red LEDs in the left front HS [SIH]/seat ventilation switch (N72/1s28) or in the right front HS [SIH]/seat ventilation switch (N72/1s29) are illuminated).
By pushing the left front HS [SIH]/seat ventilation switch (N72/1s28) or the right front HS [SIH]/seat ventilation switch (N72/1s29) up, the system is switched to stage 1 (one red LED is illuminated in the left front HS [SIH]/seat ventilation switch (N72/1s28) or in the right front HS [SIH]/seat ventilation switch (N72/1s29)).

Function with code (401a) front deluxe seats, incl. seat heating and seat ventilation
The heated seats HS [SIH] have two heating stages.
By pushing the left front HS [SIH]/seat ventilation switch (N72/1s28) or the right front HS [SIH]/seat ventilation switch (N72/1s29) up one time, heating stage 2 of the heated seats HS [SIH] is activated (both red LEDs in the left front HS [SIH]/seat ventilation switch (N72/1s28) or in the right front HS [SIH]/seat ventilation switch (N72/1s29) are illuminated).
By pushing the left front HS [SIH]/seat ventilation switch (N72/1s28) or the right front HS [SIH]/seat ventilation switch (N72/1s29) up, the system is switched to stage 1 (one red LED is illuminated in the left front HS [SIH]/seat ventilation switch (N72/1s28) or in the right front HS [SIH]/seat ventilation switch (N72/1s29)).

The left front seat heated cushion (R13/1) and the left front backrest heated cushion (R13/2) or the right front seat heated cushion (R13/3) and the right front backrest heated cushion (R13/4) are actuated by the upper control panel control unit (N72/1) depending on the heating stage that is set.
The different heating stages are implemented through pulsed actuation of the heated cushions (R13/1, R13/2, R13/3, and R13/4). In heating stage 2, the heated cushions (R13/1, R13/2, R13/3, and R13/4) are actuated with 100% heat output, in heating stage 1 with 33% heat output.
