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.

2-57
To use the shade, pull the shade handle toward the rear
of the vehicle. Latch the shade posts into the retaining
sockets on the cargo area trim panels.
To return the shade to the retracted position, pull up on
the shade handle to release the shade posts from the
retaining sockets. Let the shade move forward to the full
retracted position.
To remove the shade from the vehicle, first let the
shade go all the way into the holder. 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. 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, first make sure the shade
slot in the holder faces rearward with the round surface
facing down. Then, hold the shade at an angle and place
the shade holder tab into the slot in the driver's side trim
panel. Move the other end of the shade forward and hold
it next to the passenger's side trim panel slot.Push the button on top of the passenger's side endcap.
This will allow the shade to extend into the trim slot.
Lightly pull on the shade holder to make sure it is
secure. On Suburban/Yukon XL models there are
two slots. The slots furthest forward allow the shade
to be used if the third seat is removed or folded down.
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.

2-58 Convenience Net (If Equipped)
You may have a convenience net in the rear of your
vehicle to help 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 (If Equipped)
If you have the luggage carrier, you can load things on
top of your vehicle.
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.

2-59
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 Suburban/Yukon XL 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 glass or above the rear
load doors.
If items are loaded on the roof of the vehicle, care should
be taken not to block or damage the CHMSL unit.

cigarettes or other smoking materials. That could
cause a fire and possibly damage your vehicle.
Do not store papers and other things that burn
in your ashtrays.

2-60
To remove the front ashtray, press the retainer spring
and pull the ashtray toward you. To replace the ashtray,
place the ashtray on the slides at the side of its location
in the instrument panel. Then slide the ashtray back to
its original position.

Two accessory power outlets are located near the
cigarette lighter. Use these outlets to power mobile
telephones or other devices designed to operate with
vehicle electrical systems.
The cigarette lighter is designed to fit only in the
receptacle to the right of the accessory power outlets.
Power outlets are also located in the rear cargo area on
the passenger side and in the rear of the center floor
compartment (if equipped with rear seat audio). To use
the outlets, remove the cover by lifting the pull tab.
When not in use, always cover the rear outlet with the
protective cap.

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.
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

feature. This includes any garage door opener model
manufactured before April 1, 1982.
Be sure that people and objects are clear of the garage
door you are programming.

2-63
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. If you have previously programmed a transmitter
channel, proceed to Step 2. Otherwise, hold down
the two outside buttons on the HomeLink
Transmitter until the indicator light begins to flash
rapidly (after 20 seconds). Then release the buttons.
This procedure initializes the memory and erases any
previous settings for all three channels.
2. Decide which one of the three channels you want to
program. Hold the end of the hand
-held transmitter
about 2 to 5 inches (5 to 13 cm) away from the
surface of the HomeLink Transmitter so that you
can still see the indicator light.
3. Using both hands, press the hand
-held transmitter
button and the desired button on the HomeLink
Transmitter. Continue to press both buttons through
Step 4.
4. Hold down both buttons until you see the light on
the HomeLink Transmitter flash rapidly. The rapid
flashing indicates that the HomeLink Transmitter has
been programmed. Release both buttons once the
light starts to flash rapidly.If you have trouble programming the HomeLink
Transmitter, make sure that you have followed the
directions exactly as described and that the battery in the
hand
-held transmitter is not dead. If you still cannot
program it, rotate the hand
-held transmitter end over end
and try again. The HomeLink Transmitter may not work
with older garage door openers that do not meet current
Federal Consumer Safety Standards. If you cannot
program the transmitter after repeated attempts, refer to
ªTraining a Garage Door Opener with Rolling Codesº
later in this section or contact the manufacturer of the
unit at 1
-800-355-3515.
Be sure to keep the original hand

hand
-held transmitter may automatically stop
transmitting after one or two seconds. In this case,
you should press and re
-press the button on the
hand
-held transmitter every two seconds without ever
releasing the button on the HomeLink Transmitter.
Release both buttons when the indicator light on the
HomeLink Transmitter begins to flash rapidly.
