I've paged through the entire manual, and the navagation manual, tried the search function, all to no avail. What is the yellow icon that has the shape of a key with an exclimation point on it? I got it about 3 times yesterday, and it went away after about 10 seconds. Thanks for any help!
It means that the prius thinks you took the key out of the car with the car still running. The SKS system is momentarily not seeing your key. If you get out of the car, it will light up like that and then beep at you 4 times.
In your case the car was on, but that isn't required to get the light to come on. Just go out to your car without the key and press the 'power' button, you will get the same light...
