how much fuel left in PriusC tank when it shows empty (the last bar blinks and car beeps)

I was just curious to know how long I can drive (how much gas left in tank) when the meter gets to the last bar and car beeps, I have gone as far as 40miles but I don't want to push it until I run out of gas! Does anyone has any data on this?

It just happened to me yesterday. It beeped on the way home from work, and I drove another 10-15 miles. And then when I filled up, only filled up 8.8 gallons, so I could have went alot longer. I think it's designed to beep when you hit about a gallon of gas left.

Yesterday, I went from Baltimore to Bethesda and back on the blinking last bar! something almost 80 miles, then I filled up with 9.69 gallons!

Mine beeped yesterday too. I drove another 15 miles or so and put in 8.88 gallons.

Yeah mine beeped and drove another 7 or 8 miles with a stop along the way and put in 8.7 gallons.

I was just wondering that today, because the car beeped for the first time today. I had no point of reference, so I tanked up after about 8 or so miles and filled up 8.2 gallons

Experience my first blinking this weekend, though no beep and drove 25 miles until I filled up about 8.56 gallons.

You may have missed the beep. It beeps for a short time (maybe even just once). I believe it beeps as soon as it hits the last bar.

I've gotten to flashing, but not heard the beep. But maybe I just missed it too. I am usually listening to loud music.

I never heard bip with my C2... I think it's only for C3 and C4...

hmmm..sounds likely, although I don't know why they would leave that out with other models. I would think that should be standard across the line.

I have a C2, and it beeps...

Yup, as does mine...to the one who didn't hear, could be drowned out by wind/road noise or music/radio.

I listened to my C2 carefully at two clicks and it indeed beep. Wish it would beep once you start the car, do not think one beep is very useful.

I didn't hear mine beep.. C4.. I didn't notice how much I put when I tanked up. A beep would be nice, Either I didn't hear it or... there is a setting to turn it on/off? Hmm.. ironically im not the only one not hearing the beep, was just one time. Im gonna try to pay more attention next time, though I thought I was..

I didn't hear the beep, but I filled up a couple of miles after the last bar started blinking and it took 8.54 gallons to the auto pump shutoff.

The manual states that the low fuel warning light comes on when you have 1.2 gallons or less

It beeped and about 5 miles more down the highway I put in 8.6 gallons.

So, a little less than 1 gallon left when it beeps I guess.

What I would like to know is how low you can drain the tank before the engine quits. Can I use that last 1 gallon in its entirety?

Also I forgot to mention that the "Cruising Range" went to 0 right when the fuel tank level beeper went off. The last 2 miles on the cruising range indexed slowly to 0 over about 10 miles until it beeped!

I finally heard the Beep! Radio was changing tracks!

Here is what I found.

Drove 13.1 miles after blinking. Full engine 65mph for 8 miles then 50 MPH full engine except for 2 short redlights. AC till last 3 miles, Fuel up took 8.87 gal.

So... 8.87 + 1.2 =10.07 ....Hmm... So if 1.2 gal is correct this again confirms the false 9.5 gal tank.
