The hands-free trunk opening and closing only works when you have your vehicle key, ID transmitter or MINI digital key plus with you.
By lining yourself up to the middle of the bumper and simply kicking your foot smoothly forward and back under the center of the rear bumper, you can access the boot without needing to fumble for keys or press any buttons. When you need to close the boot, use the same motion and it will close effortlessly.
You can also customize settings for the tailgate by going to the apps menu, scroll to doors and windows and then press tailgate. From here you can set the opening height. You’ll be able to customize the hands-free trunk opening and closing options here as well.
