Holding down the unlock button for an extended period of time opens your windows and sunroof in the SHO. It does the same thing in the Lincoln MKS. However, it also works in reverse in the Lincoln. In other words, you can press the lock button and hold it and everything will close. At least in the 2010 through 2012 SHO, that function to close all the windows and sunroof with the key fob wasn't there. At the time, some of us laughed and said apparently they trust the Lincoln owners not to close a window on someone's arm, but not the Ford owners. LOL
On one occasion, in my six years of ownership, I have had all the windows down and roof open when I came out of my office. It's possible that I accidentally hit the fob button for an extended period of time...... Though to this day, I still doubt it........ and I think something else caused it. I have absolutely nothing to prove that though.
