{CAUTION:
The Rear Vision Camera (RVC)
system does not replace driver vision.
RVC does not:
Detect objects that are outside the
camera’s eld of view, below the
bumper, or underneath the vehicle.
Detect children, pedestrians,
bicyclists, or pets.
Do not back the vehicle by only looking at
the rear vision camera screen, or use the
screen during longer, higher speed
backing maneuvers or where there could
be cross-traffic. Your judged distances
using the screen will differ from actual
distances.
So if you do not use proper care before
backing up, you could hit a vehicle, child,
pedestrian, bicyclist, or pet, resulting in
vehicle damage, injury, or death. Even
though the vehicle has the RVC system,
always check carefully before backing up
by checking behind your vehicle.

Area Displayed On Screen
The image is provided by the camera located on
the rear bumper.The camera uses a special lens. The distance of
the image that appears on the screen differs
from the actual distance. The area displayed by
the camera is limited. The camera does not display
objects which are close to either corner of the
bumper or under the bumper. The spare tire and
carrier extends rearward of the rear bumper.
The area displayed on the screen may vary
according to vehicle orientation or road conditions.
Notice:The spare tire extends farther away
from rear of the vehicle than the trailer
hitch shown on rear vision camera display.
Your spare tire could hit an object even though
there appears to be enough distance on the
display between the trailer hitch and objects
behind you causing vehicle or property
damage. Do not use this system to judge the
distance between the spare tire and objects
behind you.
The following illustration shows the eld of view
that the camera provides.
194

When the System Does Not Seem To
Work Properly
The rear vision camera system may not work
properly or display a clear image in the following
situations:
In the dark.
When the sun or the beam of headlights is
shining directly into the camera lens.
If ice, snow, mud, or anything else builds up
on the camera lens. Clean the lens, rinse it
with water, and wipe it with a soft cloth.
If the back of the vehicle is in an accident, the
position and mounting angle of the camera
may change or the camera may be affected.
Be sure to have the camera and its position
and mounting angle checked at your dealer.
Extreme high or low temperatures or extreme
temperature changes can affect the image
displayed.
195

Accessory Power Outlet(s)
Your vehicle may be equipped with up to
ve accessory power outlets. The two front outlets,
if equipped, are located under the OnStar
®buttons
on the instrument panel behind hinged doors.
The two middle outlets, if equipped, are located on
the back of the center console.
There may also be an outlet located in the rear of
the vehicle near the liftgate. Remove the cap to
use the outlet. Replace the cap when the outlet is
not in use.
If your vehicle is the SUT model, there is an outlet
in the rear cargo area on the passenger’s side
of the vehicle.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 before adding electrical equipment.
Certain power accessory plugs may not be
compatible to the accessory power outlets and
could result in blown vehicle or adapter fuses.
If you experience a problem, see your dealer for
additional information on the accessory
power plugs.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or
accessory bracket from the plug because the

197

Driver’s Side Temperature Knob
The driver’s side knob is used to adjust the
temperature of the air coming through the system
on the driver’s side. The temperature can be
adjusted even if the system is turned off. This is
possible since outside air will always ow through
the system as the vehicle is moving forward
unless it is set to recirculation mode. See
“Recirculation” later in this section.
Turn the knob counterclockwise or clockwise to
lower or increase the cabin temperature. The
display will show the temperature setting
decreasing or increasing and an arrow pointing to
the driver will be displayed under and to the
left of the temperature setting.
Passenger’s Side Temperature Knob
The passenger’s side knob can be used to change
the temperature of the air coming through the
system on the passenger’s side of the vehicle. The
temperature can be adjusted even if the system
is turned off. This is possible since outside air will
always ow through the system as the vehicle
is moving forward unless it is set to recirculation
mode. See “Recirculation” later in this section.
Turn the knob counterclockwise or clockwise
to lower or increase the cabin temperature. The
display will show the temperature setting
decreasing or increasing and an arrow pointing to
the passenger will be displayed under and to
the right of the temperature setting.
The passenger’s temperature setting can be set to
match the driver’s temperature setting by pressing
and holding the AUTO button for four seconds. Both
the driver and passenger arrows will be displayed.

Automatic Operation
AUTO (Automatic):When automatic operation is
active the system will control the inside
temperature, the air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will
change to show the current driver’s set
temperature, delivery mode and fan speed.
Press the AUTO button again within
ve seconds to display the passenger’s set
temperature.
If the driver and passenger’s temperature
settings are not the same, the opposite side
temperature setting will be displayed for
an additional ve seconds. To make the
passenger’s temperature the same as
the driver’s press and hold the AUTO button
for about four seconds.
When auto is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will
run when the outside temperature is over about
40°F (4°C). The air inlet will normally be set to
outside air. If it’s hot outside, the air inlet mayautomatically switch to recirculate inside air to
help quickly cool down your vehicle. The light
on the button will illuminate in recirculation.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 74°F
(23°C) temperature setting and allow about
20 minutes for the system to regulate. Turn the
driver’s or passenger’s side temperature knob
to adjust the temperature setting as necessary.
If you choose the temperature setting of 60°F
(15°C) the system will remain at the maximum
cooling setting. If you choose the temperature
setting of 90°F (32°C) the system will remain at
the maximum heat setting. Choosing either
maximum setting will not cause the vehicle to
heat or cool any faster.
Be careful not to cover the sensor located on
the top of the instrument panel near the
windshield. This sensor regulates air
temperature based on sun load, and also
turns on your headlamps.
To avoid blowing cold air in cold weather, the
system will delay turning on the fan until
warm air is available. The length of delay
depends on the engine coolant temperature.
Pressing the fan switch will override this delay
and change the fan to a selected speed.
