A few times when I start my 07 before pulling out of garage in morning Ive gotten a symbol that lights up and goes away before I can get a good look at it. It's immediately to left of oat box in right corner of energy center display, it's sort of orange in color and I think resembles a snow flake (inside a triangle i believe), I've only caught out of the corner of my eye. I suspect this may be some sort of ice warning but haven't been able to get a good look at it. Does the 07 have some sort of icy road warning?
Yes, the Gen 2 has a temperature warning at 37°F. There's also a snowflake/road symbol in amber on the dashboard that illuminates until the temperature rises above 37 or 38.
