Remove a part to clean peee!!!

First, I'm impressed to see all of the tools in your photo.

Are you trying to remove the carpeted trim panel that is over the traction battery?

If you have removed the hardware that secures the chromed D-rings, then pull up on the trim panel. It has a few plastic clips holding it to the top of the traction battery.

Regarding the rear seat cushion, you can remove it by pulling up on the front bottom of the cushion, there are a couple of places where it snaps into the floor.

 

Any concerns/precautions of electrical shocks?

 

No, as long as the OP doesn't get cleaning fluid (or pee) into the traction battery case.

 

When I installed my subwoofer I removed the battery cover and found that 08 had two tabs of cloth holding it! I just cut them. Since I have Wet Okale seat covers, the flap was just getting in the way of the rear seat fitting properly I just timmed it off and tossed it, spare parts!! Good luck de-oderizing the carpet, urine can really stink. Hit up a pet store, or a vets office, they usually carry good deoderizer spray. We have 3 cats, the stuff works very well!!

 

Regarding the rear seat cushion: just put your hands on the bottom front of the cushion, on one side, and pull the cushion up until the latch releases. Then move to the other side and pull up until the other latch releases. Then you can move the cushion out of the car so that you can clean whatever needs to be cleaned.

Regarding the carpeted trim panel, start with one corner and pull up gently. The panel is flexible so you may be able to see under it as you start to pull it up. Try not to get liquid into the traction battery, or else you'll have a much bigger problem than a pee smell...

Pls take and post another photo after you've removed all of this, so that you'll have a permanent record of your disassembly. Also, when your Prius traction battery dies, you'll be able to do a DIY replacement and will impress your DH, friends and neighbors...

 

Pet Stores sell a spray with an enzime that neutralizes urine. You might just want to have some, not only for in aiding in this clean-up but since you have a puppy? You might just want to have some.

Febreze is nice to have as well.

 

Congratulations on releasing the trim panel! Looks like some of the plastic clips remain on the traction battery case, so you'll need to pull those out and reinstall on the trim panel before you replace the trim panel.

You don't have to worry about breaking the rear seat cushion, so just pull up on it as hard as you can, one side at a time.

 

Not so fast, we want to see another photo after you've put everything back together. That's the hard part...

 

Didn't you find any money under the seat?

 

Well, would it make sense to pull the seat belt out enough so that you can use a foaming cleaner to clean the web of the belt? When the weather heats up, any pee left will really start to smell.

Or will it be necessary to buy a new seat belt?
