The coolant level sensor is either malfunctioning or unplugged. It's either at the bottom of the overflow tank or on the side of the radiator. Fix the problem and the light will take care of itself.There is a float inside coolant tank. These tend to stick. If looking at coolant reservoir tank towards front you will see two wires running to it. Tap right above those wires and the float may float and turn off the light. You have to be loosing fluid for the need to add more. Two common problems are head gasket and heater core leaking.
