I think you press down and hold for around five seconds one of the buttons on the climate panel. . possibly the one marked with the letter A.. but I am sure someone will be along to help you.
There is a special impact 1/2 sq dr, socket that can be purchased in several different sizes specially made to fit a breaker bar or an air gun which has a left hand thread inside the socket so when the air gun tries to undo the wheel nut it automatically grips the nut and removes it from the hub... that is the easy bit, the hard bit is removing the nut from the socket afterwards .
