2003 Deville Base
this is my first winter with the DeVille. On the way home from downtown Dallas tonight my DIC flashed the message "Ice Possible". Haven't seen that one before. What triggers this? Is it the temp sensor behind the grille? Or the sensor in the middle of the dash? Or...?? where I live the weather conditions we're having are not common place. For us a "hard freeze" is 30F.
