Note the timeline at upper right.
Dawn will enter Ceres' orbit on the first days of May 2015. This animation gives a three-dimensional view of Dawn’s complex approach to Ceres. The spacecraft deftly maneuvers into orbit with its ion propulsion system, flying to RC3 orbit, which is achieved when the thrust is turned off. (The size of Ceres is exaggerated compared to the size of the orbit here.) At the end, the viewpoint shifts to provide another perspective on the unique trajectory.
