An instrument panel assembly having structure designed to restrict the motion of a panel member of the instrument panel assembly in certain situations, such as airbag deployment is disclosed. A panel member is secured to the instrument panel main body. A primary alignment post extends from the back surface of the panel member and includes a retention notch. The retention notch catches on a first edge of a first aperture of the instrument panel and restricts the motion of the panel member when a force of the second type is applied.
