Auto dim rearview mirror

[wallyuwl]

Is there a setting or something to get the rearview mirror to dim at night? Mine has it (I am 99% sure) but the lights from cars behind me are very bright at night.

It's on the same screen as the heated seats. If the icon is red, then the dimming function is active.

On 12” screen - same button that takes you to cooled or heated seats/wheel

I have 8.4" no nav.

It’s on, auto dimming Mirrors suck, I hate everyone I’ve had.

They never react fast enough and there is always a line around them that doesn’t dim. Thinking your back glass helps.

Thanks, got it. It wasn't red.

Will it auto dim only at night or does that setting dim it all the time?

I believe it only dims when the headlights are on.

It dims at night. There is a sensor on the front of the rear view mirror facing out the windshield that checks the light level. It will dim a certain amount depending on the light level. Full darkness, it will be fully dimmed.

It works anytime regardless if the lights are on or off.

Mine does not work consistently. The setting is turned on, but it doesn't actually work every time. Usually if I just cycle it off and on, it works again, but usually at least once a week it doesn't work without cycling.

It will dim once it senses light behind you. Which means you still get a quick bright reflection from the car behind you before it does dim.

Is the sensor that checks for light behind you in the rear view mirror glass? I have very dark tinted windows, which I think blocks light from hitting the sensor sometimes. My mirrors do dim, and when they do they work well, but there’s no rhyme or reason to when they dim and when they don’t. Having the dark tint takes care of most of the glare so it’s not a huge deal. I just wish they’d work consistently.

same boat like you, i have 5% on top of factory rear windows so it rarely working for me.

Yup, I had dark tint on my rear window and the auto-dim function rarely came on. The dimming function on the exterior mirrors must be tied to that same sensor, because they rarely dimmed too. My rear window was replaced due to the cracked and leaking rear window surround issue. I have not re-tinted the rear glass and now my mirrors (all 3) function as intended.
