Cargo Area Floor Drains 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 to clear any debris that has accumulated in the drain. Sunroof The vehicle may have a power sliding sunroof. The ignition must be on or in the accessory position, or Retained Accessory Power (RAP) must be active. Your vehicle also has four cargo-area floor drains (A) located under the cargo mat, if it has this feature, near the sides of the cargo area. These drains should be cleaned periodically to allow water to exit the cargo area. See Retained Accessory Power (RAP) on page 2-29. The switch used to operate the sunroof is located in the overhead console. 2-67
