To close the sunroof, press the front of the driver side
switch to the second detent position, and release.
To vent the sunroof press and hold the back of the
passenger side switch until the vent reaches the
desired position. Press the front of the passenger
side switch to close the sunroof.
If an object is in the path of the sunroof while it is
closing, the anti-pinch feature will detect the object
and stop the sunroof from closing at the point of the
obstruction. The sunroof will then return to the full-open
or vent position.
Dirt and debris may collect on the sunroof seal or in the
tracks that could cause an issue with sunroof operation,
noise or 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 sunroof.
