The cargo area has the ability to operate in many different configurations (cargo panels on or off, mid-gate up or down, rear window in or out), allowing the cargo and passenger area to be open to the environment. To allow the vehicle to operate in these configurations, it is equipped with features to help it resist the elements and protect cargo inside the cargo area. Parts of the water management system, which are designed to quickly direct water out of the cargo box, are the top drain grates, side rail channels, catch cups, mid-gate drain, cargo area floor drains and the rubber cargo floor mat.

To ensure that the water management system performs properly, ensure that the mid-gate, tail-gate and cover system are fully closed and that each element of the water management system is clean and not blocked with debris.

Important: All drain valves are removable for cleaning of the valve and the drain channel. Please note the position of the drain valve to the vehicle before removal. Improper installation of a drain valve will allow improper draining of the water and possible excessive water intrusion into the cargo/cab area.

Even when the water management system is working properly and the cargo area cover system is on, there may be some instances (heavy rains, automated car washes, etc.) when water may be present.

In the graphics below the gray arrows show water flow direction in the cargo area and the cargo area cover system. For the cargo area parts identification, refer to Cargo Area Water Management System Identification .

A large percentage of water will flow off the cargo area cover system. A small percentage of water will flow into the cargo area cover drain/seals and then into the cargo area water management system.

The small percentage of water that will flow into the cargo area water management system will drain out under the vehicle and the rear wheelwells.

The cargo panel drains/seals are located on the rear edge of each panel.

1. Remove the cargo panels.
2. Clean the cargo panel drains/seals of debris blockage.
3. Flush the cargo panel drains/seals with clean water.

The top drain grates are located near the rear window on both sides of the vehicle.

1. Remove the cargo panels or tonneau cover.
2. Remove each top drain grate.
3. Clean the grates and drains of all debris blockage.
4. Flush the gates drains with clean water.

The side rail channels are located on top of both sides of the cargo area.

1. Remove the cargo panels or tonneau cover.
2. Clean the side rail channels and drains of all debris blockage.
3. Flush the side rail channels out with clean water.

The mid-gate drain grate is located near the base of the mid-gate in the cargo area.

1. Remove the removable drain grate covering the drain.
2. Clean the mid gate drain of all debris blockage.
3. Flush the mid gate drain out with clean water.

The cargo area has four cargo-area floor drains located under the cargo mat near the sides of the cargo area.

The cargo mat has cutouts for the drains.

1. Remove or pull back the cargo mat depending on the amount of debris.
2. Clean the drains of all debris blockage.
3. Flush the four cargo-area floor drains out with clean water.
