#5703 of 7508 Turn off Automatic Reseting of MPG on 2005 Prius?
Jun 03, 2005 (8:27 pm)
Is there a way to turn off the automatic resetting of the mpg on the 2005 Prius every time you fill up. I recently traded in my 2001 Prius for a 2005 model and am very impressed with the improvements Toyota has made in the later model, but I don't like the way it automatically resets the mpg whenever you fill up with gas. On my 2001 model I hadn't reset the mpg for over 13,000 miles and my average was 44.6 when I traded it in. Now I need a pencil, paper and calculator to figure my mgp on a long trip.
On a recent trip I went 544 miles without a low fuel warning before filling up and got 52.1 mpg. On that same trip I drove another 500 + miles (from Espanola NM to Liberal KS) and averaged 54.3 mpg. I really like the new Prius.

I own a 2004 Prius and love the car. My average gas mileage is 52.4 mpg. My lowest average mileage has been 46.8 mpg. I live in a rural area and do most of my driving on the highway rather than in town. Even though the car is supposed to achieve its highest mpg in town, I have found that I get the best mileage on the highway.
The only truly annoying thing I have found on the Prius is the incessant "beeping" of the car when you put it in reverse. I would prefer that it beeped only when there was some obstacle behind the car when backing up.

It does. EPA's definitions of "City" and "Highway" don't translate to what people think. "Suburb" driving is the most efficient.

So, turn it off.

There are TONS of informative websites on the net regarding the Prius. YES, you can turn off the reverse beep. The mileage resets after each fillup. Sorry.........

Actually, it did reset. The display only shows 4 digits. So after 9999, it rolls back to 0000.
The MPG continues, but it isn't accurate anyway. All vehicles showing MPG suffer from estimates & rounding, so they are off by a little. After 9999 miles, that margin-of-error becomes more pronounced that the actual value itself.
The margin-of-error for the Classic (01-03) Prius is about 2 MPG. And since most owner's data beyond 20,000 miles on the odometer doesn't fluctuate beyond just 1 MPG over the course of a year, what you see is clearly not accurate.
In other words, calculating on-paper would have revealed your actual value was around 42.6 MPG.
Fortunately, the margin-of-error for the HSD (04-06) Prius is less, about 1.4 MPG. But even so, it still suffers from that "flat line" effect. As shown by my data spanning between 34,842 and 23,317 on the odometer... 48.5, 48.4, 48.4, 48.4, 48.4, 48.4, 48.4, 48.4, 48.4, 48.4, 48.4, 48.3, 48.4, 48.4, 48.4, 48.5, 48.6, 48.6, 48.6, 48.7, 48.8, 48.9, 49.0, 49.1, 49.1, 49.2, 49.3, 49.4, 49.4, 49.5, 49.4, 49.4

Does anyone know how much the price for a new 2006 Prius will be going up from the price of a 2005 Prius? Has anyone heard want the new model will have? Has anyone bought a 2005 Prius with "NO OPTION" package in the Chicago area?
What is VSC?
Thats all my questions
It seemed no one answered your "VSC" question...
VSC is vehicel stability control. A vehicle with VSC usually comes with a yaw (rotational) sensor that could senses abrupt change in rotation of the vehicle and intervene by
-cutting engine output power
- selectively and quickly braking proper wheels independently to retard the yaw change in an effort to maintain a smoother transition in yaw (just a smooth turn, for example)
A vehicle with VSC usually also comes with traction control and ABS because VSC replies on them at a lower level. They basically all brakes wheels but have different levels of IQs, so to speak.

VSC will automatically kick in (even if you are not touching the brake pedal) to help you keep control after turning a corner too hard.
It's pretty cool. In fact, it works so well that if you might not even realize the computer interveened with your oversteering mistake if it wasn't for the 3 beeps that sound off when it engages.

I just completed a 1400 mi round trip from San Francisco, Ca to Boise, Idaho. I learned several things on my trip. First lets get some questions answered.
John1701a informed you what VSC is. You'll find it'll kick in before YOU know something is amiss. Nice feature..good technology.
Back-up beeper - Look back on previous posts and in less than 2 mins you'll have that annoying little sound eliminated. I've read that the beeping only occurs "inside" the car and doesn't warn anyone else around. True?
The tankful odometer will reset everytime. I've carried a little "butcher book" (small notebook) in my console and have recorded every fill-up and miles per gallon entry since I bought my '04 Driftwood Pearl Pkg #9 Feb of last year. It can be a nuisance, but not that difficult to live with. I use my trip odo for total miles on a trip.
The TSB's (Toyota Technical Service Bulletins) advice dealers what problems has surfaced and what to do about them. I don't think the dealer is going to call you up and invite your car in for an update, but forums like this one alert everyone on what to be aware of. My car goes from 3 bars to a flashing last bar within 50 miles or so. I'll bring this to their attention.
A couple of weeks ago, someone backed into my left passenger door and rear panel and has to be replaced and some repainting done (the car, not the someone). I'll let you know how it went. My Toyota dealer doesn't have a body shop so I'm using the next door Chevrolet dealer body shop who I've had work done by before.
When I got out of California and into Nevada I experienced a difference in gasoline blends. California creates these exotic blends for pollution control and really cuts into mpg. (I thought it was my driving habits or terrain driven) I filled up in Nevada and throughout my stay in Boise, my mpg was over 51 compared to California's 47 mpg. My driving in Idaho was downtown and some freeway and still stayed above 51 mpg. Now here comes a surprise. I topped of in Winnemucca, Nevada and got 48 mpg with highway driving coming back from Idaho. From Winnemucca, Nv to my hometown in Calif is a distance of 360 miles. I filled up when I got home and it only took 5.6 gals to fill up!! That comes out to 64.28 mpg !! Driving back from Reno, Nv (I-80) there is a long 40 mi downgrade from the Sierra Nevada mountains to the Sacramento Valley (from Donner Summit elev 7,239 ft to Sacto valley ~100 ft elev). I "cruised" down the mountain at 60 miles per hour until I got down to 2,000 ft elev where I drove 65 mph the rest of the way. I can hardly believe my calculator. Does anyone else show mpg like this? My fuel gage shows full and I couldn't get more than 2 extra clicks of the fuel pump. Wow. My normal driving with the Calif blends usually only yields 45-47 mpg. Did someone add a couple of gallons while I was staying in Reno??? Hmm.........

I had the same experience with my new 05.
Are you taking mostly short trips (5 miles, 15 minutes) from a cold start? Someone on another site explained that the Prius doesn't operate at maximum efficiency until the gasoline engine warms up fully to a "normal" temperature. There was a detailed explanation of what is changing as the engine warms up.
I took a longer trip yesterday over the same and similar roads, and, voila, just as predicted, my fuel economy was dramatically better.
