Storage 3-3 Try sliding the crossrails forward and backward to ensure that they are correctly secured and that the levers stay tight to the cross rails. Do not stand on the plastic lower body panels when loading cargo on the luggage carrier. When the roof rack is not in use, lock one crossrail at the furthest forward position and lock the other crossrail at the furthest rearward position to reduce wind noise. Lift the lever to release and move the crossrail. Position the crossrail on both sides of the vehicle at the same time. Push the lever down to completely engage into the side rail holes. Slide the crossrails back and forth until the lock pins engage in the holes and a click is heard as the pins align and the crossrail locks.
