50 KEYS, DOORS, AND WINDOWS
If an object is in the path while
express closing, the reversal system
will detect an object, stop, and open
the sunroof again.
If frost or other conditions prevent
closing, override the feature by closing
the sunroof in manual mode. To stop
movement, release the switch.
Dirt and debris may collect on the
sunroof seal or in the track. This
could cause an issue with sunroof
operation or 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.
