Removal and Cleaning To ensure that the water management system performs properly, be sure that the midgate, tailgate and cover system are fully closed and that each element of the water management system is clean and not blocked with debris. Follow the instruction given next in this section for the proper procedures on cleaning each item of the water management system. Cargo Area Floor Drains Side Rail Channels The side rail channels are located on top of both sides of the roof and the cargo area. You may want to flush them out with clean water if you notice any debris collecting inside of them. When loading cargo into the cargo area, be careful not to damage the rails. For more information on this feature see Luggage Carrier on page 2-55 Your vehicle also has four cargo-area floor drains (a) located under the cargo mat, if equipped, near the sides of the cargo area. These drains should be cleaned periodically to allow water to exit the cargo area. The cargo mat has cutouts for the drains. You can flush the drains through the cutouts, but if the cargo area is extremely dirty you can lift up the edges of the cargo floor mat or take the whole mat out and flush the drains with water. 2-60
