The magic number is 37. I dont know how they figured out 37 when water freezes at 32.

Likely a team of 10 physics majors studying for 6 months came up with the magic number based on some combination the temperature sensor's accuracy (including accuracy based on putting it right by a heat radiator) and the difference from air temperature versus road's surface temperature (which may be colder, and thus still have ice). And yet they still failed to consider those of us who park in garages... If you factor that in, it should probably be something like 50-55 degrees F for the warning!

Ghee, I thought most of us (Including ppl in JaPan) have bridges right out of our garage/driveways which we know freezes before roads. So the warning is ample enuf for me.. Open Garage door, Start car, Pull forward to driveway, close garage door, pull off driveway onto bridge which will be slippery at 37 degrees, (make sure 4 wheel drive lock), Skate delicately over top of bridge hoping Anti Skid works well (Now in extreme sweet) going down opposite side of bridge, hit neighbors garbade can because of Black Ice, Now on solid non salted 38 degree road.
And just think, the neighbor is a cop!
Drive off safely before he gets out of house...
Repaint bumper for the 10th time... And repeat

I noticed it works like this for me...
Turn on car.
TPMS error come on.
Acknowledge with button.
Pull out of driveway.
Icy conditions warning comes on.
TPMS error comes back on.
Acknowledge with button.
I guess once an error gets raised, they all cycle through again or something.
On the happy side... snowy commute this morning and it really is rock steady.
