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.

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.
