You're correct the Fit does has this. Just changed my oil last week and saw both "oil" or "engine oil" and an arrow on the block pointing to the drain bolt. I remembered it because this is my first car ever that has had this.

This is good info, thanks. Because my last car or two didn't have a headed bolt for the trans. oil drain, the ratchet just plugged right into an indentation in the bolt head.

 

I almost drained my transmission oil when I changed my oil. I had the ratchet on the bolt for it, and thought it didn't seem like it was in the right place compared to what I saw in the manual. Glad I didn't drain it. Nothing to replace it with, and the oil pan was full of used oil residue.
