There could be many reasons. Not enough coolant or bad flow, faulty thermostat, low oil. If the coolant freezes then it will overheat. If your car continues to overheat then you should have the coolant flushed and thermostat replaced.
Yes, low coolant will cause it to overheat without the AC; that is not the only reason that will cause overheating however.
Mine came on to tell me that the coolant was low. check that. Remember to use the right kind of coolant and don't mix different kinds.
The coolant is below add in the coolant recovery tank. The engine would not overheat because only the recovery tank is low. It is also possible the low coolant sensor is bad.

Add coolant to the reservoir. If the low coolant light still stays on, replace the low coolant sensor.
