Strange Sounds

Any one figured out what those strange sound are that come from the RX400 about 5 minutes after you turn it off.

WHAT STRANGE SOUNDS ??????????????? my 2007 rx400h makes no strange sounds - perhaps it is the exhaust system cooling off - maybe a clamp is loose or too tight - can you be more specific ?

There are words in the owner's manual about such sounds being normal.

this is the fuel system venting itself automatically. the first prius hybrid has a bladder for a gas tank which can be very frustrating to fully fuel, the next gen prius and toyota/lexus hybrids came with an automatic system that vents the fuel system allowing a normal gas tank to be used.
