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.
The luggage carrier has sliding crossrails and side rails that are attached to the roof to secure cargo.
Use GM accessory racks that are compatible with your luggage carrier for transporting sports equipment. These are available through your GM dealer.
To adjust the position of the crossrails, do the following:
Do not move the rear crossrail any closer than eight inches from the antenna base in order to avoid loss of radio reception.
Notice: Loading cargo on the luggage carrier that weighs more than 75 lbs (34 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.
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.
