ACC/TJA Screen icons

Can anyone help me understand the displayed icons with TJA activated? Top left I see speedo/car/wheel icons greyed out. If I press up or down button speed displayed in green and ACC activated. The wheel icon goes white and green and back to greyed out whilst driving. What is triggering the changes and what do they mean?
