Function

Seat positions can be stored manually in the following two ways:

 Press and hold the memory switch (S91/2s9 or S92/2s9) and then briefly press the respective memory switch 1, 2, 3 (S91/2s14 or S92/2s14).

 Briefly press the memory switch (S91/2s9 or S92/2s9) and release. Within 3 s the corresponding memory switch 1, 2, 3 (S91/2s14 or S92/2s14) should also be pressed.

The driver-side front seat adjustment control unit with memory (N32/1) stores the current position of the seat motors (M27m1, M27m2, M27m3, M27m4 and M27m5). At the same time, the current positions of the steering column and the outside mirrors are also stored.

The front passenger front seat adjustment control unit with memory (N32/2) stores the current position of the seat motors (M28m1, M28m2, M28m3, M28m4 and M28m5).

 For the driver side, three positions can be manually stored for each transmitter key. In addition, when circuit 15 is switched off, the current position (last position while driving) is also stored.

For the front passenger side, three positions can be manually stored.
