Prius (2010-12) :: 2014 - Speedometer And Hybrid Sys Indicator Display Turn Off While Driving
Jan 23, 2015
I've owned a 2014 Prius Four (not IV, Roman numerals were for model year 2010) w/o Nav for just about a year now. I've encounter this mysterious condition three times now where when I turn on my car, all I see on the front displays are the READY light on the far left and the mini-display that shows the shift pattern.
* Both the speedometer/fuel gauge display on the left of the shift pattern display and the "Hybrid status" display on the right of the shift postion display are OFF.
* The car operates normally (it's not in a limp-home mode).
When I first encountered this issue and reported it to my local dealer, they suggested I take a video of it with my smartphone. I did so the car (and a copy of the video) is now at the dealership.
The second and third times this issue came up, I took videos and did some additional testing.
- When these two displays are OFF, there is no backlight to the climate control LED display underneath the stereo...
- I normally drive the car with the headlamps in "AUTO" mode. When you shift the headlamp switch to "DRL off", the two missing displays automatically power on. In any other position (Auto, corner marker lamps only, or headlamps ON position) the two displays in question turn off.
- The issue isn't with me accidentally turning the dimmer switch too low. When the dimmer switch is set to max low and the dash light sensor is covered (emulating complete darkness outside), all three displays on the dash (including the shift position display) are barely visible/look off. As the service advisor saw in my video, that's not the case.
This is clearly a safety issue ("you cannot tell how fast you are going" and "you cannot tell easily how much gas you have left without going through the infotainment display) so for now the dealership at least seems to be on my side in that something needs to be repaired. The good news is that now that the issue has been documented in my service history, they did comment that it will get fixed eventually even if the issue comes back after test. For now, the dealership is stumped so they asked Toyota for guidance on what parts to try replacing.

I have a 2005 Prius with around 115,000 miles.
I have the following warning lights on:
1) Check Engine
2) Yellow Indicator, looks like exclamation point inside a circle inside parenthesis.
3) Red Multi-information display (exclamation point inside a triangle)
4) Hybrid System Warning Light on display screen, looks like exclamation point through a car
The engine cranks up just fine and drives forward and backward in the driveway fine. Battery level indicator is blue (see image). I checked for turbulence in the inverter reservoir with the engine off and fluid was flowing.
I checked the 12V battery (using the car's measurements by holding Display and turning lights on and off 3 times) and its value was 12.1 volts without engine and A/C on and 11.8 volts with them on.
The fan in the back right passenger seat is always on now though (I don't remember ever hearing this fan noise before), regardless of engine on or not, even though it's only about 80 degrees outside and it's been sitting idle all day and all last night. It comes on pretty much immediately when the power button is pushed.

I have a Gen III Prius with 13,000 miles. It is less than a year old and I just got the Hybrid Malfunction indicator...I'm a bit upset about this and am wondering what it means. I'm not going to be able to take it into the dealership until next week, and was hoping to get some information about the indicator. It's a blurry shot but it is an exclamation mark with wavy lines below it.

While traveling speedometer and fuel level indicated blanked out. No other problems--I could see our speed by using GPS.
Toyota service said a circuit board was burned out. I searched and found numerous such problems with 04 up to 09 and eventually (in 2012) Toyota initiated an extended warranty to cover replacement of the board.

I let a friend drive my car for the first time today. Before today I always had a key with a slash through it that blinked until I started the car. Now that has disappeared and the hybrid lock indicator light is on instead. My friend left the car on, by mistake, while she went into the store. She tried repeatedly to lock it, and of course it wouldn't. Did this change something in my indicator lights?

I have some condensation forming on the inside of the plastic cover over the HSI. Is there a way to remove the plastic cover to dry it off?

For the past few days, when I press the power button, I hear the beeps and then every dashboard symbol appears - except the Hybrid System Indicator screen is completely dark. The car seems to be turned on - but when I try to put the car in reverse to back out of my garage, it won't change gears. When I go to press Power to shut it down, it takes about 5-10 seconds to shut off.
I found that opening and closing the driver's side door reset something so that the HSI turns on and the car eventually starts.

My 2010 Prius Hybrid System Indicator suddenly becoming cloudy one day. Its inside the glass cover and I initially thought it was condensation, but it hasn't gone for several weeks.
I have the Toyota Extra Care Platinum extended warranty, so took my car to a Toyota dealer. They said it was due to some chemical reaction from something I used.
I found that ridiculous because I don't use any chemicals on my car, let alone myself but they didn't budge. I have to call Toyota & see what they have to say.

I can use the wheel to dim during the daytime but can only dim can't turn off the display like I can at night. I've tried turning the lights on and adjusting the wheel but still can turn off all the way.
I would like to turn it off and just use the HUD.

I bought a used 2011 ford f150 crew cab lariat. I love it!! 5.0 liter, towing package. I notice that when I turn on the headlights, there is no indication on the display that they are on ! When I put it on high beam, I see the blue light icon on the display.
2. Another question, it has the headed mirror option, but I can't find any control that turns this on. Is this automatically controlled??
3. One more. It doesn't have daylight running lights and when I leave the headlights on and exit the vehicle, the headlight stay on! There is an auto delay digital switch on the display but I think that only applies to how long the headlight stay on when exiting the vehicle and the light switch is on auto. I am confused about the light setting on the truck.
The truck only has 24k on it so is still under bumper to bumper warranty.

During a recent vacation, while driving at night, the MPH display went black. I completed the drive to the hotel, resolving to change the fuse in the morning. When I started the car in the morning, the display was still black. I checked the fuse I thought should be involved (#22), but it was good. The MPG / MPG screen was still bad. Not wanting to drive an additional 400 miles back home without a speedometer, I called the closest dealership to get an appointment. The 2010 has 33K miles on it .
When we packed up and started the car for the trip to the dealer, everything was working. One week later and all is good. I plan on getting this anomaly recorded with Toyota just in case it happens again after the warrantee runs out.

I think that the EV indicator works very strangely on my 2015 Prius. Consider this: I'm driving downhill at 40mph and the EV indicator is on. As my speed increases (coasting the whole way - using neither the accelerator nor the breaks) and crosses 46mph, the EV indicator goes out. Why? I saw somewhere in the forums that 47mph is too fast for the motor-generator, and so it switches off --- but my real-time mpg indicator still shows 100mpg, which wouldn't seem to be the case if the Internal Combustion Engine has just kicked in. Why the EV indicator goes out? Should I even care?

I am trying to figure out how to turn on this display for the odometer. Surely this wasn't designed to only show avg consumption for trips right?

When I towed with my 2005 V-8 Touareg, the speedo displayed an indicator (like this - ) when the turn signals were actuated. I now have a 2009 TDI. The brake controller has just been installed and the turn signals work fine but no display.

My 5 month old 2015 Prius develops a problem. Once in a while when driving at night, the door open indicator and dome lights will come on for a moment and off right away. I assume it is cause by a loose connection or faulty sensor. Before I take the car to the dealer, is there something I can check?

Today I went in may garage and heard a humming from the rear of my 2014 prius. I assume it is the hybrid battery. This was several hours after the car had been driven. I turned the car on and then off and the humming stopped. Is this normal? I know it is common for it to hum immediately after you turn the car off for a bit, but several hrs later?

I took the Prius on a ski trip and halfway to our destination the speedometer display went blank and has not yet come back to life. It was fairly cold outside (-5 F) and I have seen other people blame the cold weather for a Generation II Prius.
