jeep doesn't see the ice

I know it's weird in summer, but my question is about ice info.
Normally, if the temperature is below or ca. 32F, there should be the "ice" information displayed on the overhead console display.
In my case, there's not. I haven't seen it even once during my 3 years spent with jeep.

When I do display self-check, it highlights all, including "ice". So, it's not the display fault.

The temperature sensor seems to be OK, too. The temperature shown is more or less correct everyday.

What's wrong then?

Ahah, there is an ice on the road in winter, here

I have owned a 93 Laredo, and currently a 95 Limited. I have never seen mine display 'ICE' in the winter. Mind you, this was in MN where every year we had -30F temps for nearly a month straight. Maybe this is a feature on the Euro version of the ZJ?

Mine flashes "ICE" for about 10 to 15 minutes after I start it when the temperature is at like 35 or less, I believe. I know the temp at which it should be displayed is not the melting point of water. I think it's actually a little higher to account for possible ice conditions when things start to melt. If it doesn't display it, I wouldn't worry about it. IIRC, there was a thread about this a couple years ago on here and some people never saw the "ICE" message while others did.

Mine also flashes "ice" at around 35 degrees or less after starting.

Yes, I believe the ice warning only shows up temporarily when the temp is just above freezing as a reminder to watch out for black ice and icy bridges. It was never meant to sense actual ice, and it doesn't show up below freezing because ice being possible below the freezing point is obvious to most folks.

OK, thank you guys. Good to know it's not only me
I was thinking something is broken, and can be fixed. If I would know what's wrong.

Maybe it's software, then...
Doesn't matter - I know when it's slippery, don't need such an info

its not just you or Jeep, its pretty much every companies mirror and/or sensor. I've driven factory equipped temp display mirror Jeeps as well as Gentex swapped mirrors/sensors from GM models into a few Jeeps now and the "ICE" display is hit or miss at best, case in point, the current compass/temp mirror and sensor I have in my 5.9 is out of a newer model Tahoe and I can be sliding sideways drifting on a sheet of black ice at 37 degrees with no "ICE" warning from the mirror yet the exact same swap I added to my TJ showed the "ICE" warning at exactly 36 degrees like clockwork. The setup I added to my TJ was literally dead on with the outside temperature yet the exact same setup in my 5.9 is off by exactly 3 degrees all the way from 28 to 90+ degrees regardless of the sensor I use or where I locate it. I pretty much just use the reading as a baseline and adjust my driving style based on how wide the slide is and call it good!

I didn't even know there was supposed to be such a thing on the screen My outside temp readings are correct to within two degrees which IMO is a good result in vehicles. However, I've never seen the ice warning on my niner and we get that kind of weather (temps hovering around freezing point) couple months a year in autumn/ early winter, and early spring.

I've seen the "ICE" warning fairly frequently on my 96 4.0 during the winter months. Don't know why it isn't given when heading up my steep/curvy long drive in the woods when conditions are just right and it turns into a glacier. Lol.

Here's my write up I did from back in my TJ days. I added it to my 5.9 so I can keep the fuel economy on the overhead console and have the compass/temp on the mirror
