Thread: Rearview mirror displays "ICE"... Never happend before

On my drive home today I noticed my rearview mirror display (onstar) reset. The screen became very bright with the whole display lit up then came back to normal. Shorty after that it began displaying "ICE" then would go back to the temp.

So for 5 seconds it will display the outside temp, then for another 5 seconds it will switch over and display "ICE"

I turned off the car and started it again, and it still displayed this. Kinda weird, but I have never seen this before... Im thinking that its warning me that there may be ice on the road, but I felt like asking here.

This is what it looks like:

Mine has done that before and I believe it does so when it gets to or below freezing and was some attempt to warn you that the roads may be icy.

Yeah... It was 22F outside

I watched it once and Im not sure what it queues off of, if it slowly drops to below freezing, it seems to take it a while to pop up the ICE. But if it rapidly drops, it seems to display it immediately, so who knows. I think it would have been better to accompany it with some audible cue as well.

Another question... Is there any use for onstar? And do you have to pay for it?

From what I have herd they are dropping the coverage for our cars and yes you do have to pay for it. It might still work if you are in a crash, but you would probably get charged big bucks afterwards.

^^I have No idea where any of that came up,

It says at any temp below 36ish degrees, it will only flash a few times when the car is started, most don't even notice it...

OnStar, Onstar is subscription based, unless you pay for it they don't watch you,

BUT The onstar system uses Cellular phone systems to communicate, and all GM cars up to 04(no sure the exact year, may be 03) use an analog cell signal, no carriers us this anymore, so you need to get an Onstar hardware update to use the service after January 08(May have been 07).... So if you have a before 04 gm and didn't get your hardware updated, your onstar doesn't work, and can't work

Regal shows ice when it is 30° or less out
