The sun visors in Model X are held in place by magnets. To protect occupants from sunlight coming through the windshield, release the sun visor from the pillar and pivot it toward the rear view mirror until the magnet snaps into place. While held in place by the magnet, you can adjust the sun visor and lower the extender to provide maximum shade.
To expose the vanity mirror, lower the visor extender then lower the mirror cover. While the cover is lowered, the mirror is exposed and lights are illuminated.
To protect front seat occupants from sunlight coming through the side window, lower the sun visor from the pillar then lower the visor extender.
