Sunroof The sunroof is also equipped with a sunshade which you can pull forward to block sun rays. The sunshade will not close when the sunroof is open. If a hand, arm, or other object is blocking the sunroof glass panel as it is closing, the glass panel will stop at the obstruction. After the obstruction is removed, the glass panel can be closed or opened. Use care not to leave the sunroof open for long periods of time as debris may collect in the tracts. Your vehicle may be equipped with a power sliding sunroof. To open or close your sunroof, the ignition or RAP needs to be active. See Retained Accessory Power (RAP) on page 2-20. Press and release the rear side of the button located in the front overhead console to express-open the glass panel and sunshade. To close the glass panel, press and hold the front of the button. The glass will not be fully seated unless the button is held until the glass stops moving. With the sunroof closed, press the forward side of the button to open the sunroof to the vent position. If the battery has been recharged, disconnected or is not working, you may need to reprogram the sunroof. To do this, start the vehicle and press the forward side of the sunroof switch until the glass panel moves to a fully closed position. Release, and press again to move to the vent position which occurs when the sunroof is fully tilted rearward. This will reset the memory and enable the sunroof to function properly. 2-62
