Actually, to be precise, it lowers at 57 mph, and raises back up at 45 mph. But yeah it does raise and lower, which is pretty cool.
the other neat feature of the windows and moonroof is that after you turn off the vehicle and remove the key, the windows and moonroof will still operate for 43 seconds (or until the front doors are opened, whichever comes first). Also, if you have a 2004+ and have a lighted 'auto' on the driver's switch (my 2003 didn't have one, are there any 2003's that did?), the light is lit until the 43 seconds or a door is opened.
All the little things, not to mention big things, that toyota put into this vehicle continue to "sell" me every day. I love my 4r!
Now if I could just raise the back window from remote...
