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. 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 or your vehicle. Be sure you do not cover the roof marker lamps or the Center-High-Mounted Stoplamp (CHMSL), located above the rear glass, with cargo. To prevent damage or loss of cargo as you're driving, check often to make sure that the cargo is still securely fastened and that the crossrails are tight. Stop Tabs If your vehicle has a sunroof, it will have crossrail stop tabs placed in the siderails. These tabs prevent you from moving the crossrails past the opening of the sunroof and loading cargo too far forward. Cargo loaded too far forward could fall onto the sunroof and into the passenger compartment. Loading cargo too far forward could also cause the OnStar and navigation system (if equipped) to function improperly or not at all. Vehicles with the off-road lamps will have additional stop tabs placed in the siderails to prevent you from moving the lamps too far rearward, causing them to shine into the optional sunroof opening. 2-61
