Hummer 2010 H3 - Manual (Page 44)

2-18 Keys, Doors and Windows
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.
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.
Sunshade Operation
The sunshade automatically opens
with the sunroof. Manually pull it
shut after the sunroof is closed.
To adjust the sunshade, push it
backward or pull it forward to the
desired position. The sunshade
cannot be adjusted further than
the current closed position of the
sunroof.
