Display won't go to night mode

[Dalena]

Has anyone had problems with their display not going to night mode? It makes using the Nav system at night impossible because it is too bright. It used to work, but stopped recently. Just looking for ideas before discussing it with the service center.

Thank you.

You need to adjust the dimmer control to the left of the steering wheel...it's probably just turned up all the way.

I was using the dimmer to go to night mode for almost a year. Within the last month it stopped working. As I said, it worked before, but now it goes just barely grayer, then stops before going dark.

hmmm, dunno, does the dimmer still work...in other words, if you go into night mode can you adjust the brightness at all??

I guess it's might simply be that your dimmer switch has gone bad as it sounds like there is some change in the brightness of the display when you turn your lights on.

Yeah, I agree with Speed. There's a setting in there somewhere (I'm away from Priapus right now) in the four-screen setup menu in which you can tell the MFD to never go into night mode. Or maybe it's somewhere else. I have nothing on front of me to confirm how to do this, but I've seen it and I know it's an option. Your MFD isn't broken.

Anyone?

The dimmer switch dims everything else, and the display goes slightly darker. Before the map would go to an almost black background, now it goes only slightly grey. I checked all of the settings, and they are the same as they were before. The setting for night mode lets you change colors, but not turn it off or on completely.

Well, I'm thinking that it will have to go in for service after all. It's always a little more scary to bring it in when I don't have any additional information to bring too.

Thanks for the ideas.

Have you double checked your not switched to day mode?

Switch your lights on, press the display button (top left) there should be a day mode button. Make sure its off.

Otherwise, it could be that a wire has worked loose and the display doesnt know the lights are on, and thus stays in day mode. In that case its goto a workshop.

There is a seperate contrast and brightness controls on/for the MFD.

I don't have the car with me to try it myself. While in day mode try adjusting brightness and contrast. Then try it while in night mode. You may just have your night settings way to bright.

From the Prius manual:

Push the “DISPLAY” button to display
the “Display” screen.
Contrast and brightness adjustment
CONTRAST “+”:
Strengthens the contrast of the screen.
CONTRAST “–”:
Weakens the contrast of the screen.
BRIGHTNESS “+”: Brightens the screen.
BRIGHTNESS “–”: Darkens the screen.

Victor's exactly right here. After noticing that the car wasn't switching to night mode, the next day, when I had some time to fiddle with things, I was trying to find the 'day mode' button to turn it off, and was having trouble... I went through every possible menu several times... including some unlikely ones. Finally :idea: , I tried flipping on the lights (to see if I was still stuck in day mode), and there it was! (you have to press 'display' also). But the day mode button only shows up when the lights are turned on. [edited - AND the brightness control must NOT be in the highest (dentent) position. If the brightness control is in the brightest position, the day mode button goes off as well. Additionally when that control is in the highest position, the nav display seems to go to day mode anyway. So to turn off 'day mode' (if it's on) you have to turn the lights on and make sure the control is not maxed out, then it'll toggle between night and day mode. Hope this helps.]
