I assume that your particular vehicle came with the driver assistance "nannies" package. My '18 GT1 does not have any of that. But my '19 Premium has the lot. Read your owner's manual. It will be a slog trying to explain everything here. I will offer that the only driver assistance feature I use is setting the distance in smart cruise. The car automatically takes care of the rest, even braking to a complete stop at intersections, and resuming speed to maintain distance, and the set cruise speed when available in traffic.
