Electrical manual adjustment
In the case of seats with electrical adjustment and memory functions, the manual adjustment switches
located in the seat are read by the seat adjustment control unit. The control unit, in turn, drives the
4 adjusting motors and adjusts the seat to the desired position.
In the case of seats with electrical adjustment without memory function, no control unit is used.
The 4 adjusting motors are controlled directly by the manual adjustment switch.
Only terminal 30 is required for adjusting the seats. If a power-down level of the energy management control
unit is set, seat adjustment will not be possible or, if so, only to a limited degree.
Saving settings and adjusting the seats using the programming buttons
The settings described above can be saved by pressing the SET button and then pressing one of the two
memory location buttons. The SET function remains enabled until the red function indicator LED in the button
goes off. An acoustic signal is given as feedback when a setting has been saved successfully. Again, the
prerequisite is that the memory block ON/OFF switch is set to "ON".
Saved settings can be retrieved as follows:
● If the driver door is open and "terminal 15 = OFF", the mirrors, driver seat and steering column or front
passenger seat can be adjusted to the pre-configured positions by pressing briefly one of the two Save
buttons.
● If the driver door is closed or "terminal 15 = ON", the Save button must be held pressed until the
adjustment procedure is completed. The adjustment procedure can be interrupted by releasing the Save
button.
Saving settings and memory adjustment using a remote control key
The current mirror, driver seat and steering column positions can be saved to a remote control key as follows:
– The settings are saved after closing the driver door and locking the vehicle with the remote control key.
– After unlocking the vehicle with the remote control key and opening the driver's door, the mirror, driver
seat and steering column are adjusted to the positions saved to the remote control key. The front
passenger seat does not have this function.
However, the function described above will only work properly if two basic requirements are met:
– The menu item "Remote Control Key" must be set to "ON" in the MMI Car Menu under "Systems", "Seat
Settings", "Driver Seat".
– The memory block ON/OFF switch must be set to "ON".
