GMC 2006 Sierra - Manual (Page 176)

Sunroof
The vehicle may be equipped with a power sliding
sunroof. To open or close your sunroof, the ignition
must be on or Retained Accessory Power (RAP) must
be active. See Retained Accessory Power (RAP) on
page 2-23 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.

Customization on page 3-64 for more information.
