Automatic Reversal System
The sunroof/sunshade is equipped
with an automatic reversal system
that is only active when the sunroof
is being operated in express-close.
If an object is in the path of the
sunroof while it is express-closing,
the reversal system will detect the
object and stop. In the event of
closing difficulties like frost or other
conditions, it is possible to override
the reversal system. To override the
reversal system, close in manual
mode. To stop the movement,
release the switch.
Initializing
After a power failure, the sunroof
operation may be limited. Have the
system initialized by a dealer
technician.
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.
