What makes white smoke come from the tailpipe when it is first cranked after sitting for a while on a 2004 Lexus RX330?

If you live in a humid climate it just could be condensation in the exhaust or it could be oil sepping into the combustion chamber and being burned on start up. If you have high milage I would get it checked out by a dealer.
