2-20 Retained Accessory Power (RAP)
(If Equipped)
Your vehicle may be equipped with a Retained
Accessory Power (RAP) feature which will allow
certain features on your vehicle to continue to work up
to 20 minutes after the ignition key is turned to OFF.
Your radio, power windows, sunroof (if equipped), and
OnStar

System (if equipped) will work when the
ignition key is in RUN or ACCESSORY. Once the key
is turned from RUN to OFF, these features will continue
to work for up to 20 minutes or until a door is opened.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won't start in any other position
-- that's a
safety feature. To restart when you're already moving,
use NEUTRAL (N) only.
NOTICE:
Don't try to shift to PARK (P) if your vehicle
is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine gets warm.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive
heat can damage your starter motor. Wait
about 15 seconds between each try to help
avoid draining your battery or damaging
your starter.
2. If it doesn't start within 10 seconds, push the
accelerator pedal all the way to the floor, while you
hold the ignition key in START. When the engine
starts, let go of the key and let up on the accelerator
pedal. Wait about 15 seconds between each try.

Exterior Lamps
The control on the driver's side of your instrument panel
operates the exterior lamps.
Turn the control clockwise to operate the lamps.The exterior lamp control has three positions:
(Off): Turning the control to this position turns off all
lamps, except the Daytime Running Lamps (DRL). It
also puts the system into automatic headlamp mode.
(Parking Lamps): Turning the control to this
position turns on the parking lamps, together with
the following:

Sidemarker Lamps

Taillamps

License Plate Lamps

Instrument Panel Lights

Roof Marker Lamps (If Equipped)
(Headlamps): Turning the control to this position
turns on the headlamps, together with the previously
listed lamps and lights.
You can switch your headlamps from high to low
-beam
by pulling on the turn signal/high
-beam lever.
A circuit breaker protects your headlamps. If you have
an electrical overload, your headlamps will flicker on
and off. Have your headlamp wiring checked right away
if this happens.

2-48 Fog Lamps (If Equipped)
If your vehicle has fog lamps, use them for better vision
in foggy or misty conditions.
The fog lamp button is
located on the left side of
the instrument panel.
Your parking lamps and/or low
-beam headlamps must
be on for your fog lamps to work.
Press the button to turn the fog lamps on. Press the
button again to turn them off. An indicator light will
glow in the button when the fog lamps are on.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps in
the dark without turning on your headlamps.
The fog lamps will go off whenever your high
-beam
headlamps come on. When the high beams go off, the
fog lamps will come on again.The fog lamps will be cancelled after the ignition is
turned off. If you still want to use the fog lamps after
you restart the vehicle, you will need to press the fog
lamp button again.
Auxiliary Roof Mounted Lamp Switch
(If Equipped)
If your vehicle has this feature, this switch includes
wiring provisions for a dealer or a qualified service
center to install an auxiliary roof lamp.
This switch is located
on the center of the
instrument panel near
the comfort controls.
When the switch wiring is connected to an auxiliary
roof mounted lamp, pressing the switch will activate
the lamp and illuminate an indicator light near the
switch. Pressing the switch again will turn off the roof
mounted lamp.

2-60 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.
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.

After moving a crossrail, be sure it is securely locked
into the siderail.

2-61
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.
Ashtrays and Cigarette Lighter
Front Ashtray
The front ashtray is located near the center of the
instrument panel. Pull on the bottom of the ashtray door
to open it.
NOTICE:
If you store paper or other things that burn in
your ashtrays, they could be set on fire by
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.
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.
To use the cigarette lighter, push it in all the way, and let
go. When it's ready, it will pop back out by itself.
NOTICE:
Holding a cigarette lighter in with your hand
while it's heating can make it overload, damaging
the lighter and the heating element. Just push the
lighter all the way in and let go. When it's done,
it will pop back out by itself.
Sun Visors
To block out glare, you can swing down the top and
bottom visors (if equipped). You can also swing the
bottom visor from side
-to-side. Your visors may have
an extension that can be pulled out for additional
glare protection.

2-66
Sunroof (If Equipped)
Your vehicle may be equipped with a power sliding
sunroof. To open or close your sunroof, the ignition
or RAP needs to be active. See ªRetained Accessory
Powerº in the Index.
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. The sunshade will
not close when the sunroof is open.
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 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
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.

3-9 Rear Air Conditioning and Heating Systems
(If Equipped)
If your vehicle has one of these systems, you can
increase and decrease the airflow at the rear vents.
Depending on the system you have and the setting
selected, you can send cooled or heated air to the rear
of the vehicle.
Rear Air Conditioning and Rear Heater
(With Sunroof)
Your vehicle has the rear air conditioning and rear heater
system combination. Controls are provided to regulate
temperature, air delivery location and fan speed.
Front ControlTo adjust the airflow speed, turn the fan control knob
located on the left side to the desired setting.
To regulate the airflow location, adjust the right knob on
the control. Turn the knob clockwise for floor vent
airflow or counterclockwise for headliner vent airflow.
Generally, the instrument panel outlets are used for air
conditioning and the floor vents for heating. The control
knob can be set to any blend setting.
To adjust the air temperature, turn the temperature knob
on the center of the control panel.
For warmer air, turn the knob clockwise toward red. For
cooler air, turn the knob counterclockwise toward blue.

4-21 Before You Go Off-Roading
There are some things to do before you go out.
For example, be sure to have all necessary maintenance
and service work done. Check to make sure all
underbody shields (if so equipped) are properly
attached. Be sure you read all the information about
your four
-wheel-drive vehicle in this manual. Is there
enough fuel? Is the spare tire fully inflated? Are the
fluid levels up where they should be? What are the local
laws that apply to off
-roading where you'll be driving?
If you don't know, you should check with law
enforcement people in the area. Will you be on
someone's private land? If so, be sure to get the
necessary permission.
Loading Your Vehicle for Off-Road Driving
There are some important things to remember about
how to load your vehicle.

The heaviest things should be on the load floor and
forward of your rear axle. Put heavier items as far
forward as you can.

Be sure the load is secured properly, so driving on
the off
-road terrain doesn't toss things around.
CAUTION:

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 ªVehicle Loading,º ªLuggage Carrierº and ªTiresº
in the Index.
