GLA 200d Collision Prevention Assist inoperative

Hi,
can some one help please. All in a sudden, My collision prevention assist is not functioning. I see no errors on the display. All I see is that on the graphic display there are 2 vehicles with an exclamation mark in between. Since this came on, collision prevention assist stopped functioning.
I looked in the manual and it states that there is a menu for this bit I could not find this menu in my cluster.
Can someone assist me please
