Programming Fuel Price

Sorry if this is a repeat question, but I did try searching first.

How do you tell the Prius C how much you paid for your gas? When I filled up yesterday, it gave me the option but I pushed a wrong button and the screen went away. The dealership programmed in a very low price of $2.60 a gallon, and I'm paying at least a buck more than that and I would like to get the right price into the computer so it gives me an accurate idea of how much any given trip costs. I checked my owner's manual and could not find it mentioned there. Appreciate the help!

 

Thank you, Forza4! I knew it had to be there somewhere, I'm just surprised that it isn't indexed better.

 

Thanks, Rolo, but I was actually trying to find that screen without having to put gas in. My first few passes, I pressed a wrong button and the fuel price programming screen went away without me getting to put the right price in... so I wanted to know how to find my way back to that screen.

 

Thanks again, Rolo, though not necessary. Guess I wasn't clear enough that I had figured it out already, though it never hurts to be reminded! And, to be honest, I'm not that obsessive about getting the right price in, I was just annoyed to discover that when I purchased the car the fuel price which the dealer had programmed in was well over a dollar a gallon LESS than current gas prices... which meant that all of my "this trip cost you X" readings were significantly false.

 

I write my Fuelly information on the gasoline receipt as soon as I start the car, then use the receipt to update at Fuelly website when I am next at a computer. And, of course, I always program the price rounded up, if the gas cost $3.899 then I enter $3.90.
