Accessory Power Outlet(s)
The accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular phone.
The vehicle may have two accessory power outlets
located on the instrument panel.
To use the accessory power outlet lift the cover. The
spring cap cover closes by itself when the outlet is empty.
Certain power accessory plugs may not be compatible
to the accessory power outlet and could result in
blown vehicle or adapter fuses. If you experience
a problem, see your dealer/retailer for additional
information on the accessory power plugs.
Notice:Adding any electrical equipment to the
vehicle can damage it or keep other components
from working as they should. The repairs would
not be covered by the vehicle warranty. Do not use
equipment exceeding maximum amperage rating of
20 amperes. Check with your dealer/retailer before
adding electrical equipment.
When adding electrical equipment, be sure to follow
the proper installation instructions included with the
equipment.
Notice:Improper use of the power outlet can cause
damage not covered by the warranty. Do not hang
any type of accessory or accessory bracket from the
plug because the power outlets are designed for
accessory power plugs only.
Ashtray(s) and Cigarette Lighter
If your vehicle has this feature it is located in the center
console or on the instrument panel. Pull up on the
ashtray door to open it if it is in the console or pull
the door open it if it is on the instrument panel.
Notice:If papers, pins, or other ammable items
are put in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage the vehicle. Never put ammable items
in the ashtray.
To remove the ashtray, pull it out from the console
or from the slide out door. To reinstall the ashtray,
slide it back to the original position.
To use the cigarette lighter, if the vehicle has one, push
it in all the way, and let go. When it is ready for use,
it will pop back out by itself.
Do not use the lighter to plug in accessory devices.
Use the power outlets provided.
Notice:Holding a cigarette lighter in while it is
heating does not let the lighter back away from
the heating element when it is hot. Damage from
overheating can occur to the lighter or heating
element, or a fuse could be blown. Do not hold
a cigarette lighter in while it is heating.

Outlet Adjustment
Use the outlets located near the center and on the sides
of the instrument panel to change the direction of airflow.
Operation Tips
•Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into your vehicle.
•Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
•Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
Rear Heating System
For vehicles with a rear heating system, it lets you
adjust the amount of air flowing into the rear of the
vehicle, from the front-seating area. This feature works
with the main climate-control system in the vehicle.AUX:The thumbwheel for this system is located in the
switchbank below the audio system.9(Fan):Turn the thumbwheel up or down to increase
or decrease the amount of heated air sent to the
rear-seating area.
Q(High):This position supplies the most amount of
heat to the rear-seating area.
c(Medium):This position supplies half the amount
of heat to the rear-seating area.
3-21

R(Low):This position supplies the least amount of
heat to the rear-seating area.
9(Off):Turns the rear heating system off.
Rear Air Conditioning and Heating
System
For vehicles with a rear heating and air-conditioning
system, it maintains the temperature, fan speed and air
delivery for the rear-seat passengers only. It also works
with the main climate-control system in the vehicle.
Use this control panel to maintain a separate
temperature setting. Adjust the direction of the airflow
or adjust the fan speed for the rear seat passenger(s).A. Fan Control
B. Air Delivery Mode Control
C. Temperature Control
If the vehicle has a 135 inch (343 cm) wheelbase,
a rear control panel for this system is located in the
second row behind the driver in the rear of the vehicle.
The temperature, air delivery mode, and the fan speed
can be adjusted for the rear seating area by a rear seat
passenger.
AUX (Auxiliary):Turn the fan knob on the front climate
control panel to AUX to let rear seat passengers use
the control panel in the rear seating area. This disables
the front control panel. To return control to the front
panel, move the fan knob out of AUX.

StabiliTrak®Indicator Light
For vehicles with the
StabiliTrak®system, this
light comes on or flashes,
according to the description
table for the StabiliTrak
system.
For more information, seeStabiliTrak

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. It also
provides an indicator of how hard the vehicle is working.
During a majority of the operation, the gage will read
210°F (100°C) or less. If the vehicle is pulling a load or
going up hills, it is normal for the temperature to fluctuate
and approach the 250°F (122°C) mark. If the gage
reaches the 260°F (125°C) mark, it indicates that the
cooling system is working beyond its capacity.
