I can't speak to the specific lights that come on, but the first time my dashboard lit up like a Christmas tree it was because the gas cap wasn't fully tightened. Scary as hell when it happens out in NE New Mexico, where's there's literally nothing around for twenty miles.
This actually got me to buy a code reader, and it's one of the best tools I've ever bought. There are cheap Bluetooth ones on Amazon, but I got an old-school wired one from Harbor Freight. It gives great comfort to know why a light came on rather than wonder if the car is about to explode. Seriously. Buy one.
