Entrance/exit aid steering column adjustment function

Entrance aid

Functional prerequisites

 Position measurement works perfectly

 Driver's door open (ignition/starter switch is removed) and

 Entrance/exit aid is switched on

Function

When the driver's door opens (ignition/starter switch is removed)

the entrance/exit aid function is triggered with a message sent from the left front seat adjustment control module, with memory (M32/1) to the left front SAM control module (N10/6). This control module actuates the tilt adjustment motor (up/down) (M20m2) via the left front fuse and relay module (K40/6) until the steering column has moved into the uppermost position. Positioning takes place at high speed until just before the end position. The last 2.5 mm are covered at low speed. Moving the steering column back to the driving position is triggered and takes place at low speed when the ignition/starter key is inserted in the ignition/starter switch when the door is closed. The steering column is moved into the driving position last stored for this key.
