A combiner head-up display (HUD) system includes a combiner mirror and a combiner holder supporting the combiner mirror. The combiner holder includes first and second holder arms. The HUD system also includes a combiner HUD body supporting a first knob. The combiner HUD system includes an elevation link connecting the first knob and the first holder arm. A rotation of the first knob causes the combiner mirror to move from a stowed position to a display position or from a display position to a stowed position. A second knob is supported by the combiner HUD body and is disposed substantially opposite the first knob. A threaded rod connects the second knob and the second holder arm. When the combiner mirror is in the display position, a rotation of the second knob causes the combiner mirror to adjust a display angle between the fore-aft axis and the combiner mirror.
