Check and see if you have coolant on reservoir if yes then your low coolant sensor on your reservoir is bad or :Not Connected:. Sensor is located bottom of coolant reservoir. Or maybe you need to reset your information display...
Right, first make sure you have proper coolant level and that the wiring and connection is good.
The sensor is a float in the bottom of the reservoir. Over time sediment will accumulate and cause the float to stick in the low position. You can try taking the reservoir out and cleaning it, that worked for me for a while, but I ultimately replaced it.
If you replace the reservoir and it still showing that error make sure that you press reset on dic after 2nd start it should go away. 2nd some non oem reservoirs dont fit the sensor connector well and its loose . I had to remove the gasket thing around it to make sure it fits to the dorman one i got. Might be bad plug as well so i would test it.

Disconnect the harness and put a jumper in the connector. If the message goes away, no wiring problem. If not, check for voltage on the YEL/BLK wire and ground on the BLK wire. If you don't have both, start tracing wires.
You can test the sensor itself by holding the reservoir upside down and checking for continuity between the pins.
