After normalization, keep switch pressed in "Lift" direction.
The slide/tilt sunroof stops for 5 seconds in the final raise position after normalization. It then moves into the "`Closed" position (learning of the "Closing from raising" curve)
The slide/tilt sunroof then moves into the "Open" end position and immediately back into the "Closed" position (learning of the "Closing" curve)
Release switch.

NOTE:

The entire operation lasts approx. 75 secs.
Learning of the curve is terminated when the switch is released
If the switch is released in the meantime, the entire procedure must be repeated
On completion of successful initialization, the corresponding messages in the check control and the control display go out
Carry out function check (tip function, anti-trapping protection and, if necessary, comfort function)
