Storage Areas
Glove Box
To open your glove box, lift up the latch and pull the
door open.
Cupholder(s)
Your vehicle is equipped with cupholders for the front
and rear passengers.
The cupholders are located in the center console for the
front passengers and on the rear of the center console
for the rear passengers.
To use the front cupholders, press down on the access
door and release. The door will then open. Push the
door back down
to close it.
To use the rear cupholders, pull down on the door
located on the back
of the console.
Center Console Storage Area
Your vehicle has a console compartment between the
bucket seats.
To open it, press the button on the side of the console
and swing the console lid open.
The console may be equipped with an accessory power
outlet inside. See
Accessory Power Outlets on
page 3- 17.
The rear of the console also has a cupholder that
swings down for the rear seat passengers
to use.
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
Ibs. (91 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 side rails and fasten it
securely to the luggage carrier. Put the main weight
as far forward as
you can.
2-42

Don’t exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, see Loading
Your Vehicle on
page
4-44.
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.
0 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 sideraiis are
damaged.
front crossrail approximately 18 to
24 inches
(46 to 58 cm) rearward
of the front supports.
For the purpose of wind noise reduction, locate the
0 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.
2-43

Sunroof
Your vehicle may be equipped with a power sliding
sunroof. To open or close your sunroof, the ignition
needs
to be on or RAP needs to be active. See
“Retained Accessory Power” under Ignition Positions on
page 2- 18.
Press and release the rear side of the button located in
the front overhead console to express-open the glass
panel and sunshade.
To close the glass panel,
press and hold the front of the button. The glass will not
be fully seated unless the button is held until the glass stops moving.
With the sunroof closed, press the
forward side of the button to open the sunroof
to the
vent position.
The sunroof
is also equipped with a sunshade which
you can pull forward to block sun rays.
If a hand, arm, or other object is blocking the sunroof
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 tracks.
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 button until the glass panel moves
to
a fully closed position. Release, and press again to
move to the vent position which occurs when the sunroof
is fully tilted rearward. This will reset the memory and
enable the sunroof to function properly.

Automatic Headlamp System
When it is dark enough outside and the headlamp
switch is in AUTO, your automatic headlamp system will
turn on your headlamps at the normal brightness
along with other lamps such as the taillamps,
sidemarker, parking lamps, roof marker lamps and the
instrument panel lights. The radio lights will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch
to the off position and then
release.
Your vehicle has a light sensor located on the top of the
instrument panel. Be sure
it is not covered, or the
system will be on whenever the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems
so
that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system will only be affected when
the light sensor sees a change in lighting lasting
longer than the delay. If
you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage,
it will take approximately
one minute for the automatic headlamp system to
change
to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in the full bright position. See ”Instrument
Panel Brightness” under lnterior
Lamps on page 3-76.
Lamps On Reminder
If a door is open, a reminder chime will sound when
your headlamps or parking lamps are manually turned
on and your key is out of the ignition. To turn off
the chime, turn the headlamp switch
to off or AUTO and
then back on. In the automatic mode, the headlamps
turn off once the ignition is in LOCK and the headlamps
on at exit delay ends
(if enabled in the DIC).
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others
to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
first sold in Canada.

Care of Your CD and DVD Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics
with iubricants internal to the
CD mechanism.
Cleaning the Video Screen
Pour some isopropyl or rubbing alcohol on a clean cloth
and gently wipe the video screen. Do not spray
directly onto the screen and do not press too hard or
too long on the video screen.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged.
If the mast should ever
become slightly bent, you can straighten it out by hand.
If the mast is badly bent, as it might be by vandals,
you should replace it. Check occasionally to be sure
the mast is still tightened
to the cowl. If tightening is required, tighten by hand,
then with a wrench one quarter turn.
XMTM Satellite Radio Antenna
System
Your XMTM Satellite Radio antenna is located on the
roof
of your vehicle. Keep this antenna clear of
snow and ice build up for clear radio reception.
The performance of your XMTM system may be affected
if your sunroof is open.
Loading items onto the roof of your vehicle can interfere
with the performance of your
XMiM system. Make
sure that the XMTM satellite antenna
is not obstructed.

Environmental Concerns
e
e
e
Cargo on the load floor piled higher than
the seatbacks can be thrown forward during a sudden stop. You or your
passengers could be injured. Keep cargo
below the top of the seatbacks.
Unsecured cargo on the load floor can be
tossed about when driving over rough
terrain. You or your passengers can be struck by flying objects. Secure the cargo properly.
Heavy loads on the roof raise the vehicle’s
center of gravity, making
it more likely to
roll over. You can be seriously or fatally
injured if the vehicle rolls over. Put heavy
loads inside the cargo area, not on the
roof. Keep cargo in the cargo area as far
forward and low as possible.
You’ll find other important information in this manual.
See Loading
Your Vehicle on page 4-44 and Tires
on page 5-55.
Off-road driving can provide wholesome and satisfying
recreation. However, it also raises environmental
concerns. we recognize these concerns and urge every
off-roader to follow these basic rules for protecting
the environment:
e
e
e
e
e
Always use established trails, roads and areas that
have been specially set aside for public off-road
recreational driving; obey all posted regulations.
Avoid any driving practice that could damage the
environment
- shrubs, flowers, trees, grasses - or
disturb wildlife (this includes wheel-spinning, breaking down trees or unnecessary driving through
streams or over soft ground).
Always carry a litter bag
... make sure all refuse is
removed from any campsite before leaving.
Take extreme care with open fires (where permitted), camp stoves and lanterns.
Never park your vehicle over dry grass or other
combustible materials that could catch fire from the heat of the vehicle’s exhaust system.
