GMC 2009 Sierra - Manual (Page 134)

The rails are notched at each end which allows the
tie-downs to be removed and placed on another rail. To
remove, pull the locator pin out and slide the tie-down
to the end of the rail and pull back.
To remove or install cargo tie-downs at the front of the
bed, slide the corner cap towards the center of the
bed to expose the rail notches. To remove the corner
cap, pull either edge away from the rail.
To remove the system, loosen the toggle bolts on each
rail until they can be removed from the bed of the
truck. To replace the system, place the toggle bolts and
rails into their original locations and tighten them to a
torque setting of 12.5 ft-lbs (17
Y ).
If the system is removed to install a bed liner, make
sure there is no bed liner material in the installation
points.
Notice: If you tie down cargo using the horizontal
slots on the top of the pickup box, you may damage
the box. Using the horizontal slots on the top of the
pickup box for tie-down locations may cause damage
to the pickup box and would not be covered by your
warranty. Only use the tie-down loops if you do not
have the cargo management system.
Sunroof
If your vehicle has a power sliding sunroof, the ignition
needs to be turned to RUN, or the Retained Accessory
Power (RAP) must be activated to open or close
the sunroof. When RAP is active, the sunroof will work
for 10 minutes after the ignition is turned off, or until
the driver’s door is opened. See Retained Accessory
Power (RAP) on page 2-23 for more information.
There are two sunroof
switches located in the
overhead console above
the rearview mirror.
Vent: From the closed position, press the rear of the
passenger’s side switch to vent the sunroof. To close the
sunroof, press and hold the front of the passenger’s
side switch.
