Display/navigation - day or night mode

Our Gen 3, Trim V has long bothered us with a display that doesn't seem to automatically adjust brightness from day to night. Is this not a basic feature that it should have or have? Believe it's highly likely we've missed that option in the settings, but if others can confirm, that would be nice. Driving at night with a white map creates substantial glare/distraction in the driver's visual field. Thank you.

 

I've searched for an auto-dim option; where in the menu is it located; or is it a physical switch?

 

I was wishing that were the case. Would you expect this to apply to a 2010 (Trim V)? Hitting DISP only gives us the screen you see in my profile pic. Have scoured through all the other settings in setup — unfortunately, still not seeing it.

 

Found the dimmer - this is a parent's car which I only drive a few times a year upon returns to the US, hence my lack of familiarity. The dimmer has a notched position at one end of its range, which locks the display into day mode. Was not aware of this. Mods sound interesting though.

 

There's also a button adjacent the dimmer panel; its function is unclear — fog lights? Graphic bore odd resemblance to that of dryer mode on a Japanese bidet...

 

See profile pic for the button mentioned.

 

Using the dimmer tonight, rolled.out of the notch position, it dims the instrument display far too much, even at its brightest position. Coupled with a need to use headlights during daytime long-distance freeway driving, it's clear the auto dim is too extreme — almost illegible. Guess it just needs to be manually operated but a parent doesn't like to modify settings.
