They don't. The auto-windows on the later cars are much more complicated than the normal power windows on the older cars....it is part of the "convenience control system"

And what a great system it is But it is a pretty cool feature over the early cars. I also like the hold key in door and all the windows shut and sunroof shuts. I only wish all the windows could auto open by holding the key the other way.

Only the front windows are auto-down though. The rear ones you still have to hold. I'm not sure if you could install a set of four "front" switches to get the rears to function the same. Doubt it.
