My 2004 325Cic has that feature too. Totally bone-stock, no special programming required.
its amazing what you can find in your owners manual. This feature is in there (along with valet-mode setting with the glove box/trunk, turn signal lever down leaves turn signal on after parking, adaptive headlights move with your steering, headrests move up/down with seat setting controls,....)
