'06 Prius: Numerous dash lights on while driving

Okay folks, I've got a bit of a problem here!

I have an '06 Prius with ~170k miles on it. I bought an extended warranty, and it's scheduled for diagnostics for an AC issue next week. However, I was driving my wife to work when this happened (she snapped the picture, not me):

Cruise Control shut off, but the car handled just fine. We weren't far from our destination, so I got her there, parked it, and shut it off. I powered it back on after a minute or two, and only the check engine light came on.

I haven't checked the fuses yet (too dark and too high traffic where I am), and I'm not the most knowledgeable when it comes to cars. Any ideas as to what this could be/what can be done about it (for my own edification, since the warranty will cover the repair)? Any recommendations for what I should say to the dealer/mechanic when I take it in?
