I just went for a cruise, and I noticed for the first time that my OBC kept switching to display the TEMP after a few minutes of hitting another button like DATE, etc. This was the first time I drove the car when it was cold ... it's about 30 degress out right now ... so I was wondering if this is normal? Does the OBC default to showing the TEMP when it's cold out to remind you that the road might be icy?
