2007 GMC Sierra 1500 Pickup Owner's Manual - Page 205

Sunroof The vehicle may have a power sliding sunroof. To open or close the sunroof, the ignition must be on or Retained Accessory Power (RAP) must be active. See Retained Accessory Power (RAP) on page 137 for more information. The sunroof control is located on the overhead console. Press the rear of the control to open the sunroof to the vent position, then press the rear of the control again to express-open the sunroof. To close the sunroof, press and hold the front of the control. The control must be held until the glass stops moving, so that the sunroof will be fully seated. The sunroof also has a roller sunscreen that can be used to block the rays of the sun. The roller sunscreen can be manually operated with the sunroof in an open or closed position. To open the sunscreen, press up to unlatch it and roll it back. To close, pull it forward and latch it to the close position. If the battery has been recharged, disconnected, or not working, the sunroof may need to be reprogrammed. To do this, start the vehicle and press forward on the sunroof control until it moves to a fully closed position. This resets the sunroof memory, enabling the sunroof to function properly. 205
