"The light indicates that the fluid in your radiator is low. Check the overflow tank for the correct level. Park car on level ground & check when fluid is cold. There is probably a sensor in the overflow tank that may need to be cleaned or the electrical connector is loose."
So If I check the level and it's down, fill it to the proper level ... sounds like I don't need to clean or fiddle with the connector if the light does not reappear. I just moved and cannot find my service/owners manual. Going to sell the car unfortunately

.. Just don't have garage space anymore.
Thanks for your help...!
