My Ride: 2004 545 SMG + Sports Black with Truffle brown interior
Why does the car send a warning that looks like a snowflake when the weather is cold? Is it to warn you to alter your driving or is it a drastic change in temp that could affect road conditions?

rookie mistake....
do a search for "black ice" on this forum. You will get your answers
And do drive carefully when that gong sounds!

That warning occurs when the temperature reaches 37? F or colder.

37 degrees F is when black ice can occur
32 degrees F is when water freezes
So yes, both of these temperature points affect road conditions and you should alter your driving style accordingly.
