Storage 4-13 Roof Rack System { WARNING If something is carried on top of the vehicle that is longer or wider than the roof rack - like paneling, plywood, or a mattress - the wind can catch it while the vehicle is being driven. The item being carried could be violently torn off, and this could cause a collision and damage the vehicle. Never carry something longer or wider than the roof rack on top of the vehicle unless using a GM certified accessory carrier. For vehicles with a roof rack, the rack can be used to load items. For roof racks that do not have crossrails included, GM Certified crossrails can be purchased as an accessory. See your dealer for additional information. Notice: Loading cargo on the roof rack that weighs more than 91 kg (200 lbs) or hangs over the rear or sides of the vehicle may damage the vehicle. Load cargo so that it rests evenly between the crossrails, making sure to fasten cargo securely. To prevent damage or loss of cargo when driving, check to make sure crossrails and cargo are securely fastened. Loading cargo on the roof rack will make the vehicle's center of gravity higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or abrupt maneuvers, otherwise it may result in loss of control. If driving for a long distance, on rough roads, or at high speeds, occasionally stop the vehicle to make sure the cargo remains in its place. 4. Take the storage strap and wrap it around the package. Finally, attach the hooks to the webbing and place the straps inside the top-box storage compartment. Cargo Tie-Downs The vehicle has cargo tie downs, located in the rear cargo area. These can be used to secure cargo. The tie downs can also be used to secure the cargo cover panel strap system, if the vehicle has one. For more information see Cargo Cover Panels on page 4‑6.
