Prius (2004-09) Fuel :: Mpg Readout On The Screen Around 44.7 To 45.0 Mpg
Jul 4, 2015
We've only had the car for a week but I'm puzzled by what I'm seeing for the mpg on the screen. At no time has the screen indicated an average mpg of outside the range of 44.7 to 45.0 mpg. This is despite filling it up, resetting the trip meters and immediately heading up the Cajon Pass twice while the instant fuel economy indicated 25 mpg or less. I understand the inconsistency of calculating at the pump because of the bladder but doing that has worked out to 2 fills in the high 30s, one in the high 40s and one of 53 mpg. Yet the car still reads 44.7 to 45.0.
It's not a big thing because I don't depend on it; I tend to fill the car when it goes below 1/2 full and over time I will have enough pump calculations to give me a fairly accurate depiction of my average mpg.

How accurate is the mpg readout on that display screen on the Prius. How is it measured.

I have a 2000 Passat. Have any of you had an issue with you MFA unit. My red screen (which reads out the trip mileage/fuel mileage) has had a long term problem. My screen is gradually losing the red lines (LED).
I had one line burn out and now a second red line in the screen will not light up. In essence, my screen is gradually losing lit lines on the screen. I had this problem when I first bought my car new. I had the entire MFA unit replaced due to this issue under warranty. However, the replaced screen is now exhibiting the same problem.

We have an 04 GX-470. Most of the time the fuel gauge and the range readout work OK. However, sometimes, the fuel gauge works, but the range shows 0 miles, or they both don't work - fuel gauge shows empty and range = 0. My wife says she thinks she's seen the gauge = empty but the range still showing xxx miles - I haven't seen that.
We've been to 2 different Lexus dealers, paid for diagnostics at both and gotten no fix. In fact, they have both said they can't find anything wrong.
To my way of thinking, these would both get their initial information from the same source - some sort of sender unit on the fuel tank. However, as both gauges do not always go out together, I'm inclined to think that this probably isn't the cause. I would think that the range readout comes from some calculations done by the onboard computer.

So I got my car today (2005) and I love it! I have some questions about it. When I was driving back from the dealership, I was watching the energy screen. The temperature was about 28F and it was mostly highway driving between 65-75 MPH.
During the drive, I kept noticing the yellow arrows flashing on for 500mS, then go off, then come back on in a few seconds. I wasn't able to keep the yellow arrows on consistently. There didn't seem to any sequence to it, it just seemed random. The battery never dropped below 7 bars except when I was going slow and it was always green when I was going slow. Also, the only time the battery went to 8 bars was when I braked hard and that was one time.
I would have thought the car would have used more of the battery to assist but at the same time my MPG was over 50 (51.1 to be exact) so I'm thinking this is normal. Is it?

I am interested in having an MPG readout on my back bumper, maybe next to the tag. Nothing large and in your face, but something someone might notice as they cruised along behind or next to me. So that might even mean dynamic brightness to prevent people from being blinded at night, or it being a distraction.

So maybe it is just my incompetence on this.... however, I was putting my second tank of gas in the 2016 and the Fuel Filler door will not shut...
Not only that but since the door will not shut, on my dash screen it keeps saying "Refill Ready" every 5-10 seconds.

We have noticed something strange with the dash in our new 2012 Prius. While driving at dusk and turning the headlights on the dash readout can go completely dark. Leaving only the gear selection indicator visible. This can be completely disorienting and dangerous. This happens if the dimmer wheel is set in the lowest position. It will turn back on if the dimmer wheel is moved up from the lowest setting.
I can recreate the issue parked by simply having the headlights on and dimming the switch all the way down. It will shut off the speedometer, MPGmeter, and Hyrbrid indicator screens.

My outside temp readout seems to be stuck at 61-64 degrees and that won't allow the auto select to come on if I have it set at say 72 degrees. It has been working really great up till about a week ago.

I already searched and seemed to only find info about, no backlight but lcd readout was still working. My backlight reacts to the lights being turned off and on; so I know it works but just no numbers. I noticed it on the way to work after the truck had been sitting in the hot sun for a while but When I got off work after dark around 11:00pm it worked all the way on the drive home, but I went to grab a bite and it no longer worked. I figure it could have something to do with sitting in the heat? It's the stx cluster with only the speedo and no tac if that makes a difference. I really don't want to have to drop cash on a new cluster.

I can change my nav system radio for just a radio? I am not smart enough to make the nav work and the light from the backup camera wipes out my night vision.

The touch screen calibration is off. I have to push areas about 1/2 inch above the true area to get response. I've tried the power button/lights on off to get to the diagnosis screen but it first goes to the system check screen. At that point the menu button in upper right is inaccessible because the area needed to be touched is above that beyond the screen area. Is there another way to get to the diagnosis menu to ultimately get to the touch screen calibration?

My prick of a husband punched the lcd screen in our 08 prius and the display cracked. We can't install it ourselves, so buying the parts secondhand and installing them ourselves is not an option.

I am due to make a 400 mile round trip business trip today. Go out and start the car, and the screen display is black. The MFD. None of the buttons on it work, either - I have the beep ON, no beep. I turned it off, waited about 1 minute and tried again, still nothing. Went for a short drive (took the dogs to the park where they can run), it was off for about 35 minutes. Still nothing for the short drive back home. I mean short, this is less than 2 miles one way.
I can still access the a/c and the radio from the steering wheel. I can see my speed, fuel etc, that is fine. It is just the display monitor. This came out of the blue, I have not noticed any issues at all.

I got a message on my screen that has since disappeared. It read "There is a problem with the transmission "P" lock mechanism. Park your car on a flat surface and fully appy parking break.
What does this all mean?

After driving 20 min at 40 mph, I came to a traffic stop. The engine was still running, the battery was at 75% full, outside temp 80, A/C set at 75. I noticed the MDF showed no engine running at all. But I can feel a little vibration, which tells me that the engine speed was very low, and not constant, at/below idle speed.
When I finally get home and park the car, the battery was green! Basically the engine kept running even for the last 5 min when I drove at 30 mph.
Does that indicate something wrong?
My car is a 2004 at 222K miles. 12V Battery changed 3 years ago, PCV, spark plugs changed 6 month ago. I've noticed sometime that HV battery is weaker than before, easier to get high engine speed when picking up at 50 mph +.

The info screen on my 2005 Prius shows up black. When I push one of the buttons, it gradually goes to its normal brightness, stays that way for about 10 seconds, then goes black again. The buttons all work while its lighted.

I have a 2009 Prius with 65,000 miles and have recently noticed sensitivity trouble with the touch screen. At times it will not react to my button presses and other times if I touch one part of the screen the touch will be registered in another area of the screen. Usually I turn the screen off (if I am able to get the touch of the off button to register) and restart later.

We just bought a 2004 with 46000 mi. The screen does not register till about 5 to 8 miles down the road. Let me be clear it comes on but nothing works such as heat, radio, gas consumption. The radio and heat work off the steering wheel, they just don't register on the screen right away.
