From BMW:

Note
When the BMW Performance sport seat is retrofitted, the seatbelt reminder function for the passenger seat is deactivated.

The driver must ask the passenger to put on his or her seatbelt before setting off. The function of the passenger airbag is not affected by the seatbelt reminder function being deactivated. In the E92 the automatic belt feeder is deactivated when the BMW Performance sport seat is retrofitted. The purchaser should be made aware of this fact when buying the seat!

Hope this helps.
