    I have a 2015 Prius w 60k miles. For 2 months my right blinker would sometimes blink erratically, especially upon start up or if the temperature was below 40.
    Last night, my dash was dark when my headlights were on -- with the exception of the far right headlamp and cruise control indicators. No mph, no gas tank, nothing. Help???

    Could be a bad combo meter, but start with the 12 volt health

    When I first got my 2010, the display would be completely black when I turn the headlights on and I couldn't figure out why. Turns out it was just set to turn off when the headlights are on. I don't know if the 2015 has the same thing, but there is a small dial to the left of my steering wheel, easy to miss, that will let you adjust the brightness of the display when the headlights are on. If the dial is turned all the way down, your display will turn off completely. Just turn it up a bit and the display should come back on, assuming it's not technical errors.

    The dimmer switch dims most, but not, all of the dash. It appears there are at least 3 different levels of dash lights: the deepest I think is what is called the combo meter; the most shallow has the headlights and cruise control icons; the middle appears to be the car regeneration system and gears. Only the shallowest were visible. I'll check battery.

    On mine, it completely turns off everything on the dash and the radio lights.
