Luggage Carrier You can adjust the crossrails to handle loads of various sizes. Just loosen the slider knobs at each end of the crossrail and move them to where you want them. Make sure both sides of the crossrails are even, then tighten the slider knobs. Be sure the cargo is properly loaded. Follow these guidelines: Carrying small, heavy loads on the roof is not recommended. Secure the load using the tie downs at both ends of the crossrails. When loading cargo directly on the roof panel, use the crossrails to keep the load from shifting. If you need to carry long items, move the crossrails as far apart as possible. Tie the load to the tie downs provided. Also tie the load to the bumpers. Do not tie the load so tightly that the crossrails or side rails are damaged.
