umm...it warns you that there may be Icy conditions outside.


is that what u were trying to ask or ??

 

it's a warning that your z's gonna start slipping all over the road. jk.

 

I am assuming you are asking "What For?". It has alerted and helped me on more than one occasion!

 

It tells you that your date is frigid.

 

That too.

 

I think its funny that it comes on at 36 degrees. I dont know about other areas of the country, but sunny and 36 outside in North Carolina doesnt exactly warrant conditions necessary for "icing."

 

not being funny nor am I a weather man, but other factors besides air temp could cause icing at higher than 32deg..just a friendly reminder from the folks @Nissan engineering I guess?

 

Im no weather man either, but i am educated. I do know that "other" ordinary factors other than temperature will not cause icing. Wind chill temp. for example may be well below freezing while the "actual" temp. may be 40 degrees. Wind chill is an approximation used by meteorologists to evaluate how the temp "feels" outside with the wind blowing. Water does not care what it "feels" like outside rather it requires 32 degrees in reality to freeze.

I dont know why our cars alert us for ice at 36 degrees.

 

You are probably educated, but lack a little common sense.
It takes time for ice to thaw, lakes can be frozen at 50 degrees in the spring.

At night, there can be icy patches all over the place even if temp is above freezing, expecially on bridges.
This might not happens on a sunny day in NC, but once again, this car is not designed for NC only.

Tons other cars do the samething, Beemers' icy indicator light comes on at 3 degrees C.

 

I glad you have used some of your redneck degree MyZ4U2C...but actual road temp (which maybe colder the air temp), precipitation (snow, freezing rain etc. can occur at higher than 32 deg) could cause icy road conditions..with air temps @36/37 degrees...but thanks for the edjamacation

 

Good points jedoublery.....i was just more interested in why 36 degrees as the cutoff number. I guess like you said, since conditions vary then 36 is probably as good a number as any in the 30's.

 

BECAUSE.... it can freez (below 32 deg F).. then warm up (36 deg F) .. but there can still be ice on the ground... so it can very well be 36 deg with ice on the ground

 

i glad too, but the redneck quip is kinda unfair. just cause the guy is from north carolina, doesn't mean he's a redneck.

 

Well, i actually didn't post this to ask what it is, but i guess i wasn't clear at all...

It's the first time i saw it and decided to take a picture of it and share it for those who haven't seen it...

Some of you say 36 degrees is the temperature that will prompt this feature but i think it is 38... I have another picture that shows 37 and still "Icy"...

 

Two reasons why it comes on at 36.

First. It is not a totally acurate means of meausement. Our cars do not always give the exact tempearature.

Second. The metal around and below bridges are not exposed to the friction and heat of the exaust by passing cars. Thus, those parts of the roadways are usually a little colder than the temps on top of the roads. By setting the alert to come on at 36/37 it gives a warning that ice may indeed be present.

 

Yeah, mine came on today at 37 degrees in the Gorman Pass leaving SoCal.

 

Owner's Manual has it...
It comes on at 3 C for Canadian models...
not sure about F

 

i got it today with a temp of 38 F..
