The warning message still reads "Check Washer Fluid". Fill the Windshield Washer Reservoir. Inspect and adjust to correct level. Turn the engine on and try out if all the sprinklers (windshield and headlamps) work the way they are supposed to. There might be a slight delay (1-2 seconds) shooting the washer fluid out because there could be some air trapped in the lines. Check if nothing is leaking around the Windshield Washer Fluid Reservoir and right underneath it and under the car.
