After arrival, follow the signs to the Car Rental. When you arrive at the first set of stairs, use the escalator/ or stairs to your left. They will bring you to the second floor/departure level (if you are taking the stairs right ahead to the ground floor, you are coming to another car rental area and the parking). When you are reaching the second floor/ the departure level, just go straight ahead for approximate 100 meters through the hall. You will then see the Enterprise/ Alamo/ National area and desks in the middle of the hall at the left.
