Yes. Use distilled water.
What was the temp when the light flashed?
Since you are in a cold climate and get sub freezing temps, you don't want top add a lot of water. A cup or 2 is fine. Beyond that , get some Porsche coolant and mix up some to top off your tank.

****** Warning******* do not mix different coolant types, make sure what ever you are adding is the same type as what is in there, otherwise you could make goo
