What is causing my car to run hot and almost over heat. I checked the fluid and on 2003 Mercedes-Benz ML500

fluid was checked in the tank and that is full. when i am driving the car it goes from 40 to about 100. than I need to put the heat on to bring down the temp. Sometimes it almost goes to 120 near the orange. What can be causing this?
