our X3 has a function that I cannot get it to repeat when I want it to, but when opening the car it will roll down the front windows all the way and the rear's part way to cool the car (i think) before you get in.
maybe you hit the open button without knowing? our X3 will actually "hear" the open command from within our house from about 40/50ft.
