Function requirements for actuating the steering column in the exit position 

Actuation of the steering column in the exit position 

To make it easier to disembark from the vehicle, the steering column is moved into the disembarkation position (steering column upwards) when the function requirements are met.

The steering column up/down motor is actuated via the front SAM control unit.

Function requirements for actuating the steering column into the driving position 

Actuation of the steering column in the driving position 

In order to move the steering column into the driving position after disembarkation, the steering column is moved into the driving position (steering column downwards) when the function requirements are met

The steering column up/down motor is actuated via the front SAM control unit.

Abort conditions 

IMPORTANT Apart from the steering column the driver seat is also adjusted when the easy entry/exit is actuated.

Repetition safeguard 

The alternate insertion and removal of the transmitter key leads to an interplay between approaching the driving position and the entry/exit position. In order to avoid this, the number is limited to 5 cycles.

The counter is reset if the transmitter key is turned to circuit 15R On or the door status is changed.
