NOTICE: Loading cargo that weighs more than 75 lbs. (34 kg) on the luggage carrier may damage your vehicle. When you carry large things, never let them hang over the rear or the sides of your vehicle. When loading cargo, be sure it rests on the crossrails and does not scratch or damage the vehicle. Put the cargo against the side rails and fasten it securely to the luggage carrier. Put the main weight as far forward as you can and move the rear crossrail forward as far as possible to keep the load from shifting. 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. To adjust the position of the crossrails, do the following: 1. Turn the eight knobs counterclockwise to loosen the crossrails. 2. Slide the crossrails to the desired position for loading the luggage. 3. After adjusting the crossrails, be sure to tighten all the knobs by turning the knobs clockwise. 2-52
