When manual roof panels are in the closed position, it is essential to check for both leaking and proper sealing. Leaking can occur at the seams or edges of the roof panel, which could lead to water damage inside the vehicle if not addressed. Proper sealing ensures that the panel is securely closed, preventing any gaps that could allow moisture or air to enter. Ensuring that both conditions are met is crucial in maintaining the integrity of the vehicle's interior and preventing potential damage.

Other options do not cover the complete assessment necessary for effective operation and safety. Focusing solely on leaking or sealing fails to address the need for a comprehensive check, which can lead to issues being overlooked. Performing no checks when the panels are closed could result in undetected problems that might become more severe over time. Thus, a thorough inspection is necessary to ensure both functions are effectively met.
