The message saying "Mercedes collision prevention assist plus inoperative" appears when the system lacks sufficient power to operate. This usually occurs after the car has been inactive for a while, or if the battery has been changed or drained. Once you drive the car for approximately 30 minutes, the message should disappear. If it doesn't, you should bring the car to a Mercedes dealership for the ECU to be reset. However, this is rare to happen, and if it does occur, there may be other underlying problems besides this issue.
