What is this sound?

When I shut off the engine (push button in off mode), I notice a high pitch electronic tone that persists for a minute or so, and then shuts off. Any clue what this sound is? Anybody else notice it? It's probably on the upper end of frequency that most of us can hear, so the sound might be there even if you can't hear it.

Greg is right that this is a great feature to have. I owned a Dodge Colt Turbo in 1886 that didn’t have this feature, and the manual stated that you had to let the car idle for a couple minutes before shutting down after running hard so that the turbo could cool down. That was a pain.
