2-49 Cargo Security Shade
CAUTION:
An improperly stored cargo cover could be
thrown about the vehicle during a collision or
sudden maneuver. You or others could be
injured. If you remove the cover, always store it
outside of the vehicle. When you put it back,
always be sure that it is securely reattached.
If you have a cargo security shade, you can use it to
cover items in the cargo area of your vehicle.
To use the shade, do the following:
1. Pull the shade handle toward the rear of the vehicle.
2. Latch the shade posts into the retaining sockets on
the cargo area trim panels.
To return the shade to the retracted position, do
the following:
1. Pull up on the shade handle to release the shade posts
from the retaining sockets.
2. Let the shade move forward to the full retracted position.To remove the shade from the vehicle, do the following:
1. Let the shade go all the way into the holder.
2. Then, grasping the passenger's side shade endcap,
push the shade endcap toward the driver's side of
the vehicle. The endcap should lock in the
compressed position.
3. Lift the shade up on the passenger's side, swing the
shade rearward and take it out of the vehicle.
To put the shade in the vehicle, do the following:
1. Make sure the shade slot in the holder faces rearward
with the round surface facing down.
2. Then, hold the shade at an angle and place the shade
holder tab into the slot in the driver's side trim panel.
3. Move the other end of the shade forward and hold it
next to the passenger's side trim panel slot.
4. Push the button on top of the passenger's side
endcap. This will allow the shade to extend into the
trim slot.
5. Lightly pull on the shade holder to make sure it is
secure. On Yukon XL Denali models there are two
slots. The slots furthest forward allow the shade to
be used if the third seat is removed or folded down.

2-50 Cargo Tie Downs
There are cargo tie downs in
the rear cargo area that
allow you to strap cargo in
and keep it from moving
inside the vehicle.
When not using the tie downs, flip them down out of
the way.
Convenience Net
The convenience net in the rear of your vehicle helps to
keep small loads, like grocery bags, in place during
sharp turns or quick stops and starts.
The net is not designed for larger, heavier items.
To install the net, attach the hooks to the raised cargo tie
downs. Then, attach the cord loops to the button
retainers in the side trim.
You can unhook the net so that it will lie flat when
you're not using it.
Luggage Carrier
You can load things on top of your vehicle with
this feature.
The luggage carrier has slats and siderails attached to
the roof and crossrails which can be moved back and
forth to help secure cargo. Tie the load to the siderails
or siderail supports.
NOTICE:
Loading cargo that weighs more than 200 lbs.
(90.6 kg) on the luggage carrier may damage
your vehicle. When you carry large things, never
let them hang over the rear or the sides of your
vehicle. Load your cargo so that it rests on the
slats and does not scratch or damage the vehicle.
Put the cargo against the siderails and fasten it
securely to the luggage carrier.
Don't exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, see ªLoading Your Vehicleº in
the Index.

To prevent damage or loss of cargo as you're leaving,
check now and then to make sure the luggage and cargo
are still securely fastened.
Be sure the cargo is properly loaded.
If small heavy objects are placed on the roof, place
the load in the area over the rear wheels (behind the
rear side door on Yukon XL Denali models). If you
need to, cut a piece of 3/8 inch plywood to fit inside
the crossrails and siderails to spread the load. If
plywood is used, tie it to the siderail supports.
Tie the load to the crossrails or the siderail supports.
Use the crossrails only to keep the load from sliding.
To move the crossrails, pull out on the latch release
handle at each end. Slide the crossrail to the desired
position balancing the force side to side. Push the
release handle back into the latched position and
slide the crossrail back and forth slightly to be
sure the latch snaps securely into place.If you need to carry long items, move the crossrails
as far apart as they will go. Tie the load to the
crossrails and the siderails or siderail supports. Also
tie the load to the bumpers. Do not tie the load so
tightly that the crossrails or siderails are damaged.
For the purpose of wind noise reduction, locate
the front crossrail approximately 18 to 24 inches
(46 cm to 58 cm) rearward of the front supports.
After moving a crossrail, be sure it is securely locked
into the siderail.
Your vehicle has a Center High
-Mounted Stoplamp
(CHMSL) located above the rear glass.
If items are loaded on the roof of the vehicle,
care should be taken not to block or damage the
CHMSL unit.
