Function requirements 

Abort conditions 

Easy entry/exit function 

The easy entry/exit function allows the driver to enter or leave the vehicle in a more comfortable way.

The steering column is moved upward and the driver seat is moved back.

The previous driving position is moved to when

The driving position is stored in the driver-side front seat adjustment control unit with memory (N32/1) for that particular key.

If the key is changed, a new driver seat driving position, steering column position, left electrically adjustable and heated outside mirror (M21/1) position and right electrically adjustable and heated outside mirror (M21/2) position are stored and assigned to the transmitter key.

IMPORTANT The easy entry/exit function can be configured via the instrument cluster (A1). The function can be entirely or partially (only steering column active) disabled.

Repetition safeguard 

Repeatedly inserting and removing the transmitter key causes the equipment to move between the easy entry/exit positions and the driving positions every time.

In order to prevent this, the number of cycles is limited to 5. The counter is reset when:
