Caution: If something is carried on top of the vehicle that is longer or wider than the luggage carrier -- like paneling, plywood, or a mattress-- the wind can catch it while the vehicle is being driven. This can cause a driver to lose control. The item being carried could be violently torn off, and this could cause a collision, and damage the vehicle. Items may be carried inside. Never carry something longer or wider than the luggage carrier on top of the vehicle.

If you have the luggage carrier with crossrails you can load things on top of your vehicle. If you do load things on the top of your vehicle, you must load them on the luggage carrier crossrails. Some vehicles may not have the crossrails.

Notice: Damage may be caused to the roof of your vehicle if anything is placed directly on the roof.

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, if equipped, 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.

Don't exceed the maximum vehicle capacity when loading your vehicle. For more information on vehicle capacity and loading, see Loading the Vehicle .

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.

To adjust the crossrail(s), the sunroof stop (A) must be removed.

To remove the sunroof stop, do the following:

  1. Find the tool (B) located in a bag in the glovebox labeled TOOL KIT-ACSRY.
  2. Use the tool to remove the screw located in the side rail assembly in front of the front crossrail.
  3. Repeat for the other side.
  4. Put the tool and the screws back in the plastic bag in the glove box.

To adjust the crossrails, lift the release levers on each side to unlock them. Slide the crossrails forward or backward, as needed, to accommodate loads of various sizes.

After repositioning the crossrails, push the release lever down. This will lock the crossrails in place.

Notice: Opening the sunroof when the luggage rack crossrails are not in the full-rear position could cause damage to the sunroof or luggage rack. Verify the luggage rack crossrails are in the full-rear position before opening the sunroof.

When you are done using the crossrails you must replace the sunroof stop.

To replace the sunroof stop, do the following:

  1. Put the crossrails in the full rear position.
  2. Using the tool, put the screws back into each side rail assembly. Make sure the screws are in the first hole in front of the crossrail.
