Re my Bambi on ice it has dunlop sp sport 18Inch tyres
I wonder if its the tyres??? 
It's not the tyres fault - Your 225/40R18's aren't designed for the snow and ice we have right now. You'd need proper snow tyres/chains/studs.
As said, don't worry about your coolant - just check the level.
And the alarm motion sensors may be set at to high a sensitivity.
