1-20 Keys, Doors and Windows If the sunshade is closed, it opens automatically with the sunroof but can also be express-opened/ express-closed by using the sunshade control (C) (D). The sunshade cannot be fully closed with the sunroof open. Notice: Forcing the sunshade forward of the sliding glass panel may cause damage and the sunroof may not operate properly. Always close the glass panel before closing the sunshade. The sunroof glass panel cannot be opened or closed if the vehicle has an electrical failure. Express-Open/Express-Close To express-open the sunroof from the closed or vent position, fully press and release the rear of the switch (A). The sunroof opens automatically. To stop the sunroof partway, press the switch a second time. To express-close the sunroof, fully press and release the front of the switch (B). The sunroof closes automatically. To stop the sunroof partway, press the switch a second time. Anti-Pinch Feature 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, and sunshade will then return to the open or vent position. To close the sunroof once the obstruction has been removed, refer to the "Express-Open/Express-Close" functions described previously. Do not keep the sunroof open for long periods of time while the vehicle is not in use. Debris can collect in the tracks, damage the sunroof operation and plug the water draining system.
