Removal Procedure

Notice:  DO NOT close the lift window panel with the struts attached unless the window is installed and the window adhesive fully cured. The window adds strength and rigidity to the lift window panel.

If necessary, the rear compartment lift window panel may be manually released by pulling on the manual release cables located behind the cargo compartment rear corner carpet panels.
