From the owner's manual "Sensors are positioned within the outer parts of the rear bumper. The sensors recognize a valid kick below the bumper level and allow automatic opening or closing of the powered tailgate." See attached picture. Also note that "The gesture action is a smooth kick and return motion, not a swipe motion."
