I live in Minnesota and since winter has not yet left I've noticed that whenever the computer indicates an ambient temperature of ~38 degrees F or less a chime goes off and the temp flashes at me. It will do it during start up or if during the day the temp drops below that mark while I'm driving. What is this and why is it doing it? Is it a normal warning(why?) or is there something wrong?

Thanks...

Dan,
This is a normal function. It is supposed to let you know that driving conditions may be hazardous (ice on bridges, etc.). It is however rather annoying sometimes. Like when you see snow on the road and the thing is beeping at you to let you know its cold outside. If you really hate it, I suppose you could disconnect the temperature sensor, but I'm not sure if there are any other repercussions for doing so.

My manual says the indicator goes off at +37Deg F. Mine goes off at +36 Deg F. If the temperature magically goes up to 43 Deg F, the gong will sound again.

Good luck
