Hi guys. This is my first post, I own a 2016 Max Plat and I have a question about the " parking aid " menu in " Settings". There is an item labeled " sensor " with two options; on or off. Neither is highlitghted . When I do highlight "on": and leave the settings mene and return, it is no longer highllighted. I presume that some sensor is not working but which one> There is nothing in the owner's manual and the dealer is of mu help. Any ideas about what this is ?. One other thing. The sensors on the front bumper seem to be working.

 

Is that a used car? Was the bumper replaced? If yes, did they reconnect the sensors to the wiring harness?
