On the left of the main screen under the little remote controller icon (the one you push to access the intelligent modes). It's a circle with little lines like "underdeveloped crosshairs". 2 main modes, QuickShot, like it sounds, draw a box around the subject and the camera will track it. Composition mode, draw a box and push the C2 underneath when the subject enters the box and the tracking should pick it up (not overly successful with moving cars). Further settings, Free (usual default) allows camera to rotate freely independent of directing that the drone is heading, be carful flying like this until you get used to it. It is not difficult to loose spacial awareness, especially if you are coming from a Mavic or Phantom where the camera faces forwards all the time. Free mode, camera face forwards like a Mavic or Phantom.
