Store outside mirror position 

Function requirements 

Function 

All totaled, three memories can be stored manually:

Press and hold memory switch; simultaneously actuate memory switch 1, 2 or 3 momentarily or actuate memory switch for at least 40 ms and momentarily actuate memory switch 1, 2 or 3 for 3 s.

The signal for memory request is relayed to the left front seat control unit by the left door control unit via the interior CAN. It relays the memory request to both door control units.

When switching off the motor (as of circuit 15C) and when the driver door is closed, the current position of the left and right outside mirror is stored automatically in the corresponding door control unit.

IMPORTANT When storing, also the positions of the steering column and the driver seat are stored.

Call outside mirror position 

Function requirements 

Function 

The position stored in the left door control unit and right door control unit can be called via the seat operation switch group.

For this purpose, press desired memory switch 1, 2 or 3.

The left seat control unit receives the memory request by the left door control unit via the interior CAN and relays it to the left door control unit and right door control unit via the interior CAN.

The left door control unit actuates the left outside mirror and right door control unit actuates the right outside mirror as long as the memory switch 1, 2, 3 is pressed or the position for the memory location selected is reached.

The steering column and driver seat are moved to the associated memory positions for the selected memory location at the same time when the outside mirror positions are retrieved.

IMPORTANT The last position of the driver seat, steering column and outside mirror is adjusted as of circuit 15C ON.
