Add coolant 1.5 inches above the full mark on the reservoir and that'll solve it. (hopefully)
You'll need to run the car for awhile, take a short drive and then check level again. Air in system will work its way out.
But remember, ALWAYS keep level 1.5 inches above max line and your low coolant light will stay off. Bad design on Furd's part. Yes I said FURD!
