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.
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 2-54.
Cargo Area Floor Drains
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. The drain grates can be removed by
using a flat-head screwdriver to clear any debris that
has accumulated in the drain.
