Anti-Pinch Feature
If an object is in the path of the
sunroof when it is closing, the
anti-pinch feature detects the object
and stops the sunroof from closing
at the point of the obstruction. The
sunroof then returns to the full-open
position.
Dirt and debris may collect on the
sunroof seal or in the track. This
could cause an issue with sunroof
operation, noise, 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.
