the sunroof seal or in the track.
This could cause an issue

or plugging 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.

On vehicles with a sunroof, there

The sunroof only operates when the

Accessory Power (RAP) is active.
See Retained Accessory Power
(RAP) on page 9‑40 for more
information.

first detent position.
To express open or close the
sunroof, press the open or close
