Don't exceed the maximum vehicle capacity when loading your vehicle. For more information on vehicle capacity and loading, see Loading Your Vehicle on page 4-36. 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. Loading things onto the luggage carrier can interfere with the performance of your XM™ Satellite Radio System. Notice: Loading cargo on the luggage carrier that weighs more than 220 lbs (100 kg) or hangs over the rear or sides of the vehicle may damage your vehicle. Load cargo so that it rests on the slats as far forward as possible and against the side rails, making sure to fasten it securely. When you carry cargo on the luggage carrier of a proper size and weight, put it on the slats and distribute the weight evenly. Then slide the crossrail up against the rear of the load to keep it from moving. You can then tie it down. Cargo containers must be loaded on the crossrails only. Your luggage carrier has release levers within the end of each crossrail support. 2-39
