A vehicle has a deck lid for closing a vehicle luggage compartment. The deck lid is mounted on a hinge assembly including a hinge lever pivoted on a vehicle body and a hinge arm attached to the deck lid. A trim panel lines the luggage compartment and has an oversize aperture creating a gap through which the hinge arm travels freely without interference with the trim panel during the opening and closing movement of the deck lid. A closeout panel is mounted on the hinge assembly to travel therewith. The closeout panel is sized larger than the size of the oversize aperture and upon the deck lid reaching the open position, the closeout panel will have moved with the hinge assembly to a position closely adjacent the backside of the trim panel so that the closeout panel closes the gap and prevents an observer from seeing through the gap.

A counterbalanced hinge system rotatably attaches a closure panel to a body for rotation about a rotation axis. The counterbalanced hinge system applies an assist torque to the closure panel to bias the closure panel about the rotation axis from a closed position into an open position. A pop-up system is moveable from an un-sprung position into a sprung position to apply an opening force to the closure panel. A reset system includes a connecting cable interconnecting the counterbalanced hinge system and the pop-up system. The reset system converts a portion of the assist torque applied by the counterbalanced hinge system into linear motion of the connecting cable to move the pop-up system from the sprung position into the un-sprung position automatically upon the closure panel moving from the closed position into the open position.
