The moveable roof assembly has the ability to operate in different configurations, roof opened or closed, allowing the cargo area to be open to the environment. The moveable roof assembly is designed to prevent water from entering the cargo area while the roof panel is closed. If there is water entering the cargo area from the moveable roof assembly area when the roof panel is fully closed, it will be necessary to diagnose and repair the leakage. Parts of the roof water management system, which are designed to direct water off and out of the moveable roof assembly, are the channels on each side of the roof panel and the channel in front of the roof panel.

To ensure that the water management system performs properly, ensure that all parts of the roof water management system area are cleaned and not blocked with debris.

In the graphic, the gray arrows show water flow direction off the moveable roof assembly.
