The graphic you see is shown when you try to reverse and there is a potential of a car coming from the side you may not have seen in your blind spot, so it should have given you a different audio warning and this shows up.

Does it show all the time?

Try reversing and look sides, if a car approaches from the side does this show and do you get the audio noise change to highlight this.

Mine does this as it has the 360 camera system fitted does yours?
