How does my Prius know I got gas?

I'll let others give you the answers you seek... but will take this chance to warn you that with December right around the corner - that the Prius also knows whether you've been good or bad. So be good for goodness' sake!

 

How does your Prius know you got gas?

The smart-nice person answer: When the Prius rolls down all four windows on its own. :lol:

The smart answer: The same way it knows when to add more pips to the fuel gage.

 

sensor sees the difference and resets... if you put in small amount of fuel.. sometimes it won't see it therefore it won't reset... i'm talkin bout less than a gallon

 

Since you have an 07, the mpg's do not automatically reset unless you hit the reset button, the 04 and 05's did automatically reset(I just found this out recently).

I have an '07 and mine automatically resets. In fact, last week after filling up and automatically resetting thend riving to work - about 42 miles. When I went to leave work in the afternoon it automatically reset again. I assume the sensor may have sensed a full tank with the fuel volume expanding during the day - cold morning, warm afternoon.

The miles traveled resets but not the running MPG. Or in my case, the kms resets but not the l/100 km. On the second screen, the one with the five minute bars. The odometer trip gauges are not affected.

 

It uses the fuel level sensor. In some cases it can take up to three gallons before it will register.

The 2006 and later models do not automatically reset the MPG total.

Does no one RTFM anymore. That kind of information is in the manual. You would think, (OH! excuse me I guess it is some people try and avoid at all costs) that when you drive a new car that is slightly out of the ordinary with so many wonderful magical functions that you would want to learn how they all work.

You make a good point, but you have to admit that the manual is difficult to read (and I tried!) and difficult to find any particular topic in.

Toyota would do well to hire a really good manual writer (and one that can write an English sentence woudn't hurt, either...).

 

It took me 2 days to read the manual when I first got the car & after almost a year I am still learning things that others say "are in the manual". It's a lot of absorb when you first get the car & are blown away by the video-game atomsphere of the screen & trying to remember which buttons to push when. After 2 months I still don't have the bluetooth capabilities of my new cell phone set up correctly - and I was a technical analyst & software programmer before I retired.

 

My 07 resets automatically when I fill up.

 

camner,
I've been around this great forum awhile and can vouch for the fact that 99.9% of the folks here are first class but like everywhere else in life we have a few who spend their lives being rude and miserable. Actually it is better to just consider the source and move on.
Great to have you posting here

after 23 fill-up and a daily commute of 140 miles, My 07 does NOT automatically reset. Nor does two other friends who have 07's also.

We've got abot 16K on our 07 and only recently did we (once) see the MFD reset at fill-up. However, I believe the manual says that it automatically resets when it consumes 10.00 galons of gas. I've seen that heppen once or twice (I usually reset when I fill up, but the wife does not).

 

RTFM read the friendly manual....sorry, couldn't resist.

I have a 2007 Mod 2 Prius.
I record all my fill ups.
I have to hit the reset button every time. I now have 6000 miles.
