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.
