storage bin, at the rear of the center console, and in
the rear cargo area.
To use the outlets, remove the cover. When not in

Certain electrical accessories may not be compatible
with the accessory power outlets 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 outlet.
Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your 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
installation instructions included with the equipment.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.

Outlet Adjustment
Use the slider switch in the center of the outlet,
to change the direction of the air ow. Use the
thumbwheel near the outlet to control the amount
of air ow or to shut off the airow completely.
Keep all outlets open whenever possible for best
system performance.
Operation Tips
Clear away any ice, snow, or leaves from the
air inlets at the base of the windshield that can
block the ow of air into the vehicle.
Use of non-GM approved hood deectors can
adversely affect the performance of the system.
Keep the path under all seats clear of objects
to help circulate the air inside the vehicle more
effectively.
If fogging reoccurs while in vent or bi-level modes
with mild temperature throughout the vehicle, turn
on the air conditioner to reduce windshield fogging.

Your vehicle is equipped with the following wiring
harness for towing a trailer.
Basic Trailer Wiring
If your vehicle is equipped for heavy duty trailering, the
trailer wiring harness, with a seven-pin connector, is
located at the rear of the vehicle and is tied to the
vehicle’s frame. The harness connector can be plugged
into a seven-pin universal heavy-duty trailer connector
available through your dealer/retailer.
The seven-wire harness contains the following trailer
circuits:
Yellow: Left Stop/Turn Signal
Dark Green: Right Stop/Turn Signal
Brown: Taillamps
Black: Ground
Light Green: Back-up Lamps
Red/Black: Battery Feed
Dark Blue: Trailer Brake**The fuse for this circuit is installed in the underhood
electrical center, but the wires are not connected. They
should be connected by your dealer/retailer or a
qualied service center.
If the back-up lamp circuit is not functional, contact your
dealer/retailer.
If you are charging a remote (non-vehicle) battery, press
the Tow/Haul mode switch located on the center
console near the climate controls. This will boost the
vehicle system voltage and properly charge the battery.
If the trailer is too light for Tow/Haul mode, you can
turn on the headlamps (Non-HID only) as a second way
to boost the vehicle system and charge the battery.
