First check visually that you do indeed have coolant, which it appears you've already done. Only use genuine MB coolant or Zerex G-5 mixed 50/50 with distilled water. Using anything else is asking for trouble.
If the low coolant light still comes on despite having enough coolant in the reservoir, you may have a bad float (the sensor in the reservoir). Also make sure your radiator cap is good.
If you are unsure of the age/condition of the reservoir and cap, replace the whole assembly (reservoir, tank & float).
Most importantly, you need to find out why your car overheated (bad thermostat, bad fan clutch, bad electric fan, etc.).
