Adjusting the Crossrails Adjust the crossrails to fit your load by doing the following: 4. Once you load the cargo onto the crossrails, secure it by tying it down to the crossrail support cargo tie-down loops. Do not load cargo directly on the roof of your vehicle. Be sure you do not cover the roof marker lamps or the Center-High-Mounted Stoplamp (CHMSL) (If equipped) with cargo. To prevent damage or loss of cargo check now and then to make sure the luggage and cargo are still securely fastened and the crossrails are tight. Stop Tabs 1. Loosen the lock knobs on the crossrail supports by turning the knobs counterclockwise. Only loosen them enough to allow the crossrails to slide easily. 2. Slide the crossrails to the desired position, being sure to align the lines in the side rails with the arrows on the crossrail supports. 3. Tighten the lock knobs and then try to move the crossrails back and forth to be sure that they do not move. 2-47
