Easy entry/exit feature for driver seat

To make it easier to leave the vehicle, the driver seat (up to 31.5.06) and the steering column are moved to the easy entry/exit position.

Movement to the easy entry/exit position is actuated by the following given state changes:

Transmitter key removed (A8/1)
Driver door open with circuit 15R
Driver door open with circuit 15C
Driver door opened with transmitter key not inserted

Abort conditions

Undervoltage or overvoltage
Active seat adjustment (manual or memory)
Manual steering column adjustment
Circuit change up to circuit 15 ON, both with opened and closed door
Closure of driver door (irrespective of circuit status)
Vehicle speed > 12 km/h

Approach drive position

Movement to the last stored drive position is actuated by the following given state changes:

The driver door is closed with circuit 15 On
Circuit 30 to circuit 15C
Circuit 15C to circuit 15R
Circuit 15R to circuit 15

Evaluation of the required signals and the adjustment of the seat and steering column are performed by the driver front seat adjustment control unit.

Repetition safeguard

Repeatedly inserting and removing the transmitter key causes the equipment to move between the easy entry/exit positions and the drive positions every time. To prevent this, the number of cycles is limited to five.

The counter is reset when the transmitter key is turned to circuit 15R ON or the driver door status is changed.
