Faint, high pitched sound

My wife just noticed a faint, high-pitched sound coming from her 2004 XC90 2.5T AWD when she starts the vehicle. We've got about 72,500 miles on it. The noise seems to go away after a few minutes of running. Anyone have a similar noise? Any idea what it might be? Thanks.

high pitched can be a belt squealing when cold. buy some belt dressing at an auto parts store and try spraying it on belt and see if that helps. i think this belt is self adjusting.
