Dirt and debris may collect on the
sunroof seal or in the track. This
could cause an issue with sunroof
operation, noise, or plugging 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.
