My snowflake has been on for 3 days now. It means that the outside temp is 37 degrees or below. But what's the rationale? I already know it's cold out--10 degrees wind chill, winter coat, frost on windshield, and the MFD shows outside temp.

p.s. Florida and California posters stop your chuckling.

The logic is that in the high 30s black ice and hazardous road conditions can start to form. Get the correct humidity, dew point and a temp getting close to freezing but not solid freezing and you can end up with very dangerous roads. So the yellow snowflake comes up.

This isn't all that different since most cars in production today with interior temp displays have some functionality like this. At Ford, if you have the large temp display in your vehicle it will flash ICE in the display for about a minute once 37 degrees outside temp has been reached.

If you look real closely at the yellow snowflake, it is more than just a snowflake, it is a road behind the snowflake. I'm not much on auto hieroglyphics, however if you take the time to really look at it, I think it makes the point.

Welcome to yellow snowflake season. :)

Atleast you don't have the dreaded "hurricane" hieroglyphic over the little road symbol hazard light!

Thank you, jeromep, what you write is informative. I'll look at the yellow snowflake more closely. My sympathies to Floridians and other hurricane victims--I'll put up with the cold. Only my dog eats yellow snowflakes.

At what temperature does the snowflake turn OFF? It turns on at 37 degrees and stays on if the temperature rises to 38 or 39 degrees (I presume this is just a thermostat-like fudge factor, so it's not flashing on and off all the time); and I've seen it turn off when the temperature jumped from 39 to 41 degrees, but I haven't ever noticed what it did at 40 degrees. (Yes, even I look at the road now and then! :shock: )

The indicator turns off after the temperature rises above 39 degrees. However, if the indicator is on and the temperature is above 37 degrees and you shut down, the indicator will be off when you restart.

The outside temperature probe actually records the temperature in degrees C, and then converts it to degrees F display for the US market. Since the conversion involves a 1.6F to a 1 degree C change, with rounding typically you'll only see degree changes of about 2F. So, there are many degrees F that you don't see displayed as outside temperature. Unfortunately, I do not have my nice list of displayed degrees F for degrees C table handy to post here...

I saw snow in Korea in 1952. I left there as soon as possible.
If some Govt agency offers to send you there, all expenses paid, DON'T GO.

Snowflake?

At first I thought you were talking about the little graphic which represents the fan. My bad. Haven't seen the snowflake yet but weather man is predicting a cold Thanksgiving...75 degrees. :lol: I am NOT chuckling.

I suppose everything is put into perspective. Our weathermen are telling us it's going to warm up today--we're supposed to hit 40. And we're actually welcoming the news!!
