Important: It is necessary to use the following alignment marks when aligning the front cross bar. Marks are located on the top surface of the
passenger side roof rail, and should be aligned with the arrow (1) on the crossbar. All roof rack kits include a stop clip, which should be placed
on the roof rail in the appropriate stop location. Failure to align to these marks could result in component interference and excessive wind
noise.
On vehicles not equipped with sunroofs, align the front cross bar with the On-Star stop (1), located approximately 7.5 inches behind the front outer
marking light.
On vehicles equipped with sunroofs, align the arrow on the cross bar with the sunroof stop (1), located approximately 20 inches rearward on the OnStar
stop.
