BC message “Safely stop, restart engine”

I turned the ring for the information of the on-board computer. Shortly afterwards the message “Sure stop, engine restart” came on the BC. Since I was at home anyway, I parked the car overnight in the parking lot. When I started the car this morning, the following symptoms occurred: cruise “Cruise” does not turn off and when repeatedly pressing the horn goes with it. When I press the rotary switch always remains the same angle. The flashers don’t work when I do the lever. The driving light does not turn off. That was the first thing I noticed. Who can help me there. I am grateful for any help. PS. Pictures of my moose are now also present.
