    Hey Guys,

    My dashboard light has completely gone out. So things like EV/Auto etc or Speed etc are not showing up. It is showing up but very very dark in the background. My HUD is still showing the speed.

    Do you know what caused this and how can I fix it.

    That was the first thing I tried and it didn't resolve it. Let me make sure that I am doing it right. So to set the light to Auto, I just manually revolved the knob on the left hand side of steering to align the headlight symbol to Auto. Is this correct?

    Ah, found it. There is a set of buttons on the left knee side and my knee must have pressed it. These buttons are to set the dashboard lights on high or low.

    9 times out of 10 it is human error.

    From decades of experience in tech fields, a very high percentage of human error is design error. An awful lot of user interface design invites operator error: the "human error" was by the designer.

    Many of you are probably aware of this but you can also turn off the touchscreen entirely, which is kinda nice for night drives.

    A friendly safety awareness post.
    The dash lights are on the rear tail light fuse circuit. So if the dash suddenly goes dark, your tail lights may not be working either.

    This reminds me ...

    When my gen two hit about 160,000 miles, it suddenly kept losing power when the ac went on or climbing hill. Only sometimes. The dashboard battery indicator would show almost no charge, Three different dealerships couldn't figure it out. We just stopped using the ac and muddled along.

    At about 180,000 miles, the dashboard went dark for no reason. You could still drive the car, if you could correctly guess what gear you were in. It cost about $600 to repair.

    And-- voila!-- the power issue and ac problems were cured immediately! And then Toyota retroactively extended the warranty and reimbursed us our $600!

    Was having trouble with the 12v battery but it turned out to be the ground wire was loose. Less than 12 hrs after the repair no lights on the dashboard. What was the issue and what did they repair for $600?

    If that's the cause, yeah, that's design error. Anything that's unintuitive, error-prone, is a design fail.

    I know about the dashboard light on the left at knee level. It doesn’t change anything for me.
