It should be listed on your window sticker. I could be wrong, but the Surround–View Camera is now listed as N/A w/Trailer–Tow Mirrors" as are the folding mirrors.
The Lane Departure feature had to be turned on, which took reading the manual. A little light on the dash glows green (active), gold (departure) and white (lane not detected).
Mine will provide a gentle tug, followed by a full correction if I do not respond. It the system does not receive input from the driver after a predetermined time (not sure how long that is), it will shut off.
Mine gets a little confused on two lane roads where the "right side" white line is against the grass/dirt or on roads that are not well defined.
