The 2020 CX9 Grand Touring and Signature trims come standard with a liftgate handsfree foot\-motion detection unit located on the inner surface of the rear bumper. This location is also where the accessory trailer hitch \(P/N 0000\-8E\-N31/0000\-8EN31A\) is designed to be installed. Due to this location conflict, the foot\-motion detection unit must be removed and deactivated in the MAZDA CONNECT system.
