Help! Left my windows open & it rained in my Prius!

We had a heavy thunderstorm this afternoon and my rear windows were completely down!
I have leather interior and the rear seats were really splattered and there was about 1/2 inch of water in the driver side rear hand grip. The rear floormats were wet but the carpet under them was lightly damp.
What I'm most worried about is the battery. A little water may have gone into the vent.
Can this be dangerous or will it shock me? Should I go to the dealer and have them check anything?
I've wiped down all the seats and door panels and removed the mats.

What should I do?



iPhone ?

 

Thanks!

I have since then checked under the cargo floor and everything is dry.

My remaining concern is the rear seat bench, which is like a wet sponge. I could see it becoming mildewy with the leather wrap on it.
I have figured out how to remove it and I will probably take off the leather and try to get the whole foam bench dry. I then may have to get the upholsterer to re-attach the leather.

 

Final Resolution:

The carpeting under the left rear footwell was soaked, so I tore out the felt padding underneath it and threw it in the dryer. Then I used warm dry towels under and on top of the carpeted floor liner in that area to soak up any residual moisture. By morning the carpet and pad were bone dry. I sprayed them with some lysol spray to prevent mildew or smells.

I removed the rear bench and removed the leather skin from the bench. I dried the leather skin in the dryer on a low gentle cycle until it was back to normal. I wrapped several dry warm towels around the rear bench which is a giant piece of foam with some metal reinforcements in it. It dried somewhat, but I asked my friend (who works for a dealership) about it. He said they dry interior upholstery out in the sun for vehicles that are water damaged or rained in. After 2 days of sitting in the sun of my back deck it dried out completely. Now I'm going to get a vehicle upholsterer to re-attach the leather to the rear bench.

After a bit of effort, everything is good again.

Thanks to all for their comments and insights.
