Mystery Part: What is this????????????

[monicaownsayaris]

So a deer hit my car and somehow only did minor damage, but there's this panel that came off and I'd like to replace it but I have no idea what it's called. It's this plastic piece right next to the radiator, looks like it just protects the stuff behind it but that's just my guess.

Anyhoo here's a picture of yaris I found on Google with the part correctly in place:


And here's a closeup where I outlined the part so you know exactly which piece I'm talking about:


I've looked through every diagram I could get my hands on and can't for the life of me figure out what this is.

It's a 2010 Yaris Hatchback (manual)
