Why does dash beep when exterior temp = 37 degrees?

glane21 · Sun, Jan-13-2008, 03:26:11 AM

Whenever the outside temp sensor registers 37 degrees, the 37 flashes on the dash and makes a beep. What is that all about? And yes, I ran a forum search but found no answer.

It's to warn you to look out for ice. I think it also turns your heated mirrors on.

Aha, thanks. I thought maybe it had something to do with cold weather package since my car originally arrived through Jersey docks. Though I have the window sticker and it says nothing about cold weather package on the features list.

the beep always scares me into thinking i have a tire going down

all m3's do this... cold weather pack or not.

Mine beeps too, I have the cold weather package. Warning of ice makes sense.

Yeah it beeps for the low ambient temp but says nothing if you oil pressure is low and your motor is going to blow up....go figure.

I think the heated mirrors are always on -- as dumb as that is...

Yes - the heated mirrors are on all the time. Dunno why - but since BMW has been doing that forever it doesn't seem to cause problems.
