I looked into this and found the answer in the Owner’s Guide 3rd Printing:
“To open the sunscreen: Press and release the control. The sunscreen will automatically open.
Note: For the dual panel moon roof, the sunscreen stops at the first panel. Press and release again to continue to open the sunscreen past the second panel.
To close the sunscreen: Pull down the control and release. The sunscreen will automatically close. If the moon roof is open, it will automatically close prior to closing the sunscreen.”
In case you didn’t know, the Owner’s Guide can also be downloaded/printed for free at
www.FordOwner.com > Vehicle Basics > Owner’s Manual and Videos > and selecting 2011 Explorer from the drop down menus!
Drop me a line if you have any other questions!
