Automatic Reversal System
The sunroof and power sunshade, if equipped,
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 this condition occurs, attempt to remove
th
e object, then pull and release the switch to
express close. If the reversal occurs multiple
times, the DIC message OPEN THEN CLOSE
SUNROOF will display, and express is disabled.
To operate sunroof while express is disabled,
the switch must be either pressed or pulled
and held.
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.
