yellowblue Don't exceed the maximum vehicle capacity when loading your vehicle. For more information on vehicle capacity and loading, see "Loading Your Vehicle" in the Index. To prevent damage or loss of cargo as you're driving, check now and then to make sure the luggage carrier and cargo are still securely fastened. Your luggage carrier has release knobs set in the ends of each crossrail. NOTICE: Loading cargo that weighs more than 150 lbs. (68 kg) on the luggage carrier may damage your vehicle. When you carry cargo on the luggage carrier of a proper size and weight, put it on the slats, as far forward as you can. Then slide the crossrail up against the rear of the load, to help keep it from moving. You can then tie it down. Turn the release knobs counterclockwise to unlock the crossrails. Slide the crossrails forward or back, as needed, to accommodate loads of various sizes. After repositioning the crossrails, be sure to tighten the release knobs by turning them clockwise. This will lock the crossrails in place. 2-77
