Power Outlets
Accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone, MP3
player, etc.
There are three accessory power
outlets. The power outlets located
below the climate control system,
inside the center console storage
bin, and on the rear of the center
console are powered while the
vehicle is in ON/RUN/START or
ACC/ACCESSORY mode, or until
the driver door is opened with
10 minutes of turning off the vehicle.
On the CTS Wagon there is an
additional accessory power outlet
located near the rear cargo net that
is powered at all times.
Remove the cover to access and
replace when not in use.
Notice:Leaving electrical
equipment plugged in for an
extended period of time while the
vehicle is off will drain the
battery. Always unplug electrical equipment when not in use and
do not plug in equipment that
exceeds the maximum 20 ampere
rating.
Certain electrical accessories may
not be compatible with the
accessory power outlet and could
overload vehicle or adapter fuses.
If a problem is experienced, see
your dealer.
When adding electrical equipment,
be sure to follow the proper
installation instructions included with
the equipment. See
Add-On
Electrical Equipment on page 9‑58.
Notice: Hanging heavy
equipment from the power outlet
can cause damage not covered
by the vehicle warranty. The
power outlets are designed for
accessory power plugs only, such
as cell phone charge cords.
Cigarette Lighter
The vehicle may have a cigarette
lighter. To use the lighter, push it in
all the way and let go. When it is
ready, it will pop back out by itself.
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.

Lighting 6-7
The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all the
power that is needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power, whenever
needed. It can temporarily reduce
the power demands of some
accessories.Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,
this action may be noticeable to the
driver. If so, a Driver Information
Center (DIC) message might be
displayed, such as BATTERY
SAVER ACTIVE or BATTERY
VOLTS LOW. If this message is
displayed, it is recommended that
the driver reduce the electrical loads
as much as possible. See
Driver
Information Center (DIC)
on
page 5‑27.
Battery Power Protection
This feature helps to prevent battery
drain if accessory lamps are left on.
If accessory lamps such as the
vanity mirror, cargo, reading,
console, or glove box are left on,
they automatically time-out after
about 20 minutes. To reset the
battery protection, all of the above
lamps must be turned off or the
ignition must be in the ACC/
ACCESSORY position.
Exterior Lighting Battery
Saver
The exterior lamps turn off about
10 minutes after the ignition is
turned to LOCK/OFF, if the parking
lamps or headlamps have been left
on. This protects against draining
the battery. The battery saver does
not work if the headlamps are
turned on after the ignition is turned
to LOCK/OFF.
To keep the lamps on for more than
10 minutes, turn the lamps back on
with the exterior lamp control.

Automatic Operation
AUTO (Automatic):The system
automatically controls fan speed, air
delivery, and air conditioning in
order to heat or cool the vehicle to
the desired temperature. When the
indicator light is on, the system is in
full automatic operation. If the air
delivery mode or fan setting is
manually adjusted, the auto
indicator turns off and displays will
show the selected settings.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting between
21°C (70°F) and 27°C (80°F).
Choosing the coldest or warmest
temperature setting will not
cause the system to heat or cool
any faster.
To avoid blowing cold air in cold
weather, the system delays
turning on the fan until warm air
is available. The system starts
out blowing air at the floor, but
can automatically change modes as the vehicle warms up to
maintain the chosen temperature
setting. The length of time
needed for warm up depends on
the outside temperature and the
length of time that has elapsed
since the vehicle was last driven.
3. Wait for the system to regulate. This may take from 10 to
30 minutes. Then adjust the
temperature, if necessary.
English can be changed to metric
units through the Driver Information
Center (DIC). See Driver
Information Center (DIC)
on
page 5‑27.
Q/R(Temperature Control):
The temperature can be adjusted
separately for the driver and the
passenger. Press to increase or
decrease the automatic temperature
settings.
PASS (Passenger Climate
Control): Press to set a different
temperature for the passenger. Then adjust the passenger
temperature buttons to a
comfortable setting.
Pressing the PASS button again
automatically sets the passenger's
temperature to the driver's setting.
Turning the passenger's
temperature display off does not
shut the passenger's climate control
system off.
Manual Operation
O(Power):
Press to turn the
climate control system on or off.
When the climate control system is
turned off the air inlet defaults to
outside air.
D C(Fan Control): Press the
buttons to increase or decrease the
fan speed. Pressing either button
cancels automatic fan control. Press
AUTO to return to automatic
operation. The blower may reduce
during an Onstar
®session to limit
background noise.

If the airflow seems low when the
fan speed is at the highest setting,
the passenger compartment air filter
might need to be replaced. For more
information, seePassenger
Compartment Air Filter
on
page 8‑6and Scheduled
Maintenance on page 11‑3.
H G(Air Delivery Mode Control):
Press the buttons to change the
direction of the airflow. The current
mode appears in the display screen.
Changing the mode cancels the
automatic air delivery. Press AUTO
to return to automatic operation.
The outboard air outlets always
receive some airflow in every mode,
except defrost.
To change the current mode, select
one of the following:
Y(Vent): Air is directed to the
instrument panel outlets.
\(Bi-Level): Air is divided
between the instrument panel
outlets and the floor outlets. In automatic operation, cooler air is
directed to the upper outlets and
warmer air to the floor outlets.
[(Floor):
Air is directed to the
floor outlets, with some air directed
to the windshield and outboard
outlets.
-(Defog): This mode clears the
windows of fog or moisture. Air is
directed to the windshield, floor, and
side window outlets. When this
mode is selected, the system turns
off recirculation and runs the
air-conditioning compressor unless
the outside temperature is at or
below freezing. If recirculation is
selected while in defog mode, it is
cancelled after 10 minutes.
0(Defrost): This mode clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield, with some air directed to
the side windows. In this mode, the
system automatically turns off
recirculation and runs the air-conditioning compressor, unless
the outside temperature is at or
below freezing.
This mode can also cause the fan
speed and air temperature to
increase.
#(Air Conditioning):
Press to
turn the air conditioning system on
or off and override the automatic
system. When in AUTO, the air
conditioning compressor comes on
automatically, as needed.
The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.
M(Recirculation): Press to turn
on recirculation. An indicator light
comes on. Air is recirculated inside
the vehicle. It helps to quickly cool
the air inside the vehicle or prevent
outside air and odors from entering.
Press the AUTO button to have the
system select the best air delivery
mode for the temperature setting.

Recirculation is not available in the
defrost mode and automatically
turns off 10 minutes after defog is
selected. This helps to limit window
fogging in the vehicle.
Using recirculation for long periods
of time could cause the air inside
the vehicle to become too dry or
stuffy. To prevent this from
happening, after the air in the
vehicle has cooled, select outside
air or press the auto button.
F(Outside Air):Press to turn
on the outside air. An indicator light
turns on. The outside air mode pulls
fresh air from outside the vehicle.
Outside air is always selected in
defrost mode to prevent fogging.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog or frost
from the rear window. It only works
when the ignition is in ON/RUN.
=(Rear Window Defogger):
Press to turn the rear window
defogger on or off.
The rear window defogger stays on
for about 15 minutes, before turning
off if the vehicle is moving at a
slower speed. At higher speeds, the
rear window defogger may stay on
continuously. With each additional
press, the defogger runs for about
10 minutes. The defogger can also
be turned off by turning off the
engine.
The heated outside rearview mirrors
turn on when the rear window
defogger button is on and helps to
clear fog or frost from the surface of
the mirrors. See Heated Mirrors
on
page 2‑27.
Notice: Do not try to clear frost
or other material from the inside
of the front windshield and rear
window with a razor blade or
anything else that is sharp. This
may damage the rear window
defogger grid and affect your radio's ability to pick up stations
clearly. The repairs wouldn't be
covered by your warranty.
z/{(Heated and Ventilated
Seats): Press to heat or ventilate
the seat. See Heated and Ventilated
Front Seats on page 3‑12.
Remote Start Climate Control
Operation: For vehicles with
remote vehicle start, the climate
control system automatically heats
and cools the vehicle based on the
temperature inside and outside of
the vehicle. The climate control
displays will be blank. See Remote
Vehicle Start on page 2‑11.
In cold weather the windshield
defroster and/or rear window
defogger automatically turn on.
If the vehicle has heated seats, they
will also turn on.
When the ignition is turned to ON/
RUN, the climate control system
returns to the settings used before
the vehicle was last turned off. The
heated seats will turn off,
if equipped.

Climate Controls 8-5
Sensors
The solar sensor located on the
instrument panel, near the
windshield, monitors the solar heat.
The interior temperature sensor,
located on the instrument panel to
the right of the steering wheel,
measures the temperature of the air
inside the vehicle.
The climate control system uses the
information from these sensors to
adjust the fan speed and the air
delivery, in order to maintain the
selected temperature. The system
may also supply cooler air to the
side of the vehicle facing the sun.
The recirculation mode will also be
activated, as necessary.Do not cover the sensors or the
automatic climate control system will
not work properly.
Air Quality Sensor
For vehicles with an air quality
sensor, the climate control system
adjusts to limit some exhaust fumes
from being pulled inside your
vehicle.
Press the AUTO button on the
climate control to activate the air
quality sensor. The recirculation
indicator light comes on when poor
quality air is detected. The air
quality sensor will not maintain
recirculation for an extended period
to prevent the air inside the vehicle
from becoming too dry or stuffy.
