Automatic Reversal System
The sunroof and power sunshade have an
automatic reversal system that is only active
when the sunroof and power sunshade are
operated in express-close mode.
If an object is in the path while
express-closing, the reversal system will
detect an object, stop, and open the sunroof
or power sunshade slightly.
If frost or other conditions prevent closing,
override the feature by closing the sunroof
or power sunshade 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.
