The sunroof and sunshade will then return to the open or vent position. To close the sunroof once the obstruction has been removed, refer to "Express-Open/Express-Close" earlier in this section. Dirt and debris may collect on the sunroof seal or in the track. This could cause issues with sunroof operation and noise. It could also plug the water drainage system. Periodically open the sunroof and remove any obstacles or loose debris. Wipe the sunroof seal and roof sealing area using a clean cloth, mild soap, and water. Do not remove grease from the sunroof. If water is seen dripping into the water drainage system, this is normal.
