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.

For vehicles with a luggage carrier, it allows for things to be loaded on top of the vehicle. The luggage carrier has side rails attached to the roof, sliding crossrails, if equipped, and places to use for tying things down. These allow for some things to be loaded on top of the vehicle, as long as objects are not wider or longer than the luggage carrier.

Press the lever down and align the crossrails on both sides with the holes on the siderails. Move the crossrail by hand. There will be a notable click as the pins align into the holes locking the crossrail into place.

Make sure the lever is in the down position, and that the crossrail cannot be moved by hand when it is in place.

To reposition the crossrail, pull up on the end levers of the crossrail to the upright position. This releases the pins from the holes in the siderail and allows for the crossrail to be moved into a new position.

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.

Do not stand on plastic lower body panels when loading cargo on the luggage carrier.

Do not exceed the maximum vehicle capacity when loading the vehicle. For more information on vehicle capacity and loading, see Loading the Vehicle .

To prevent damage or loss of cargo while driving, check now and then to make sure the luggage carrier crossrails are locked and cargo is still securely fastened.

When the luggage carrier is not in use, lock one crossrail at the rear most position on the siderails and lock the other crossrail above the opening of the rear door to reduce wind noise.

If equipped, a luggage carrier allows you to load things on top of your vehicle. The luggage carrier has side rails attached to the roof, sliding crossrails, if the vehicle has them, and places to use for tying things down. These let you load some things on top of your vehicle, as long as they are not wider or longer than the luggage carrier.

The roof rack crossrails lock along the straight section of the side rail.

Press the levers down until the locking mechanisms fully engage to the side rail. Make sure each lever is in the down position. The crossrail will not slide when properly engaged.

To move the crossrail, pull up on the end levers on each side of the crossrail to the upright position. This will release the locking mechanism from the siderail. Lift and place the crossrail into the new position. Press the levers down until the locking mechanisms fully engage to the side rail. Make sure each lever is in the down position. The crossrail will not slide when properly engaged.

Notice: Loading cargo on the luggage carrier that weighs more than 150 lbs (68 kg) or hangs over the rear or sides of the vehicle may damage your vehicle. When loading cargo, tie it to the crossrail and against the siderail. Lock the crossrails to the far forward and backward location to make sure the load is evenly distributed on the luggage carrier.

Do not stand on the plastic lower body panels when loading cargo on the luggage carrier.

Loading cargo on the luggage carrier will make the center of vehicle gravity higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or abrupt maneuvers. This could result in loss of control of the vehicle.

Do not 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 are driving, check now and then to make sure the luggage carrier crossrails are locked and cargo is still securely fastened.

When the luggage carrier is not in use, store the crossrail inside the vehicle. If not possible, lock one crossrail at the rear most position on the siderails and lock the other crossrail above the opening of the rear door to reduce wind noise.
