Luggage Carrier Your vehicle's luggage carrier has side rails and may be equipped with crossrails 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. The crossrails, if equipped, are adjustable, but are only designed to move a limited amount. The front and rear crossrails are not interchangeable. If you do remove the crossrails, make sure to mark them with front or rear. When replacing the front and rear crossrails, make sure to but them back in the same position they came from as the front rail is slightly longer than the rear rail. Just loosen the slider knobs at each end of the crossrail to move them. {CAUTION: If you try to carry something on top of your vehicle that is longer or wider than the luggage carrier - like paneling, plywood, a mattress and so forth - the wind can catch it as you drive along. This can cause you to lose control. What you are carrying could be violently torn off, and this could cause you or other drivers to have a collision, and of course damage your vehicle. You may be able to carry something like this inside. But, never carry something longer or wider than the luggage carrier on top of your vehicle. • The front crossrail has limited movement when traveling rearward. • The back crossrail has limited movement when traveling forward. After adjusting them, make sure both sides of the crossrails are even, then tighten the slider knobs. 2-34
