Automatic Reversal System The sunroof/sunshade is equipped
with an automatic reversal system
that is only active when the sunroof/
sunshade is being operated in
express mode. If an object is in the
path of the sunroof/sunshade 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.
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.
If water is seen dripping into the
water drainage system, this is
normal.
