Luggage Carrier Cross Rail Wind Rush Noise with Sunroof Open (Adjust Rail)

Some customers with vehicles equipped with a roof luggage rack and sunroof may comment that there is excessive noise while driving with the sunroof open.

The roof luggage rack cross bars may be positioned too far forward.

The roof luggage rack package includes stops that prevent the luggage carrier cross rail from being moved too far forward. This is necessary to avoid damage to the sunroof (if equipped), and to avoid interference with the OnStar system. It will also reduce the noise level while driving with the sunroof open.

1. Snap the stops onto the side rails at the location labeled "Sunroof Stop" as shown in the illustration above.



2. This illustration shows the cross rail and the stop clip installed in the correct " Sunroof Stop" position.
