4x4 on a 2002 How does it work?

Mine has the 4.6 with auto ,4x4 high and low, I guessing that it runs in auto all the time, since there is not light like my 95 had. How do i know it kicks in ? does it go to 4x4 when needed then go back to Auto,If so how does this work? Ive heard that there has a been a problem with some of the fords being in 4x4 and the driver not even know it , the truck thinks that the back tires are slipping. any insight will help. chris
