"Disable" was a poor choice of words. It edits the settings. I'm away from the car; so, I cannot recall the specific temperatures. But I recall that the temps that I can edit can be set to such a low number that the warning would be effectively disabled in my region. Worst case, the chime would sound only at points where, "Yeah, I know it's cold!"Does it disable it, or just move it a few degrees colder?
