A closure assembly includes a handle assembly having a grab bar. The grab bar is moveable in a normal direction relative to an exterior panel surface of the closure assembly between a retracted position and an extended position. When in the retracted position, an outboard surface of the grab bar is disposed approximately flush with the exterior panel surface. The closure assembly includes a position sensor configured for sensing the presence of an operator, and signals the handle assembly to move the grab bar into the extended position when the presence of the operator is sensed. When the grab bar is grasped, the handle assembly signals a latch mechanism to move into an un-latched position to allow the closure assembly to open.
