2011 GMC SIERRA climate settings

Black plate (6,1)GMC Sierra Owner Manual - 2011
8-6 Climate Controls
O(On/Off):Press to turn the
climate control system on or
off. Outside air still enters the
vehicle, and is directed to the
floor. This direction can be changed
by pressing the mode button.
Recirculation can be selected once
you have selected vent or bi-level
mode. The temperature can also be
adjusted using either temperature
button. If the air delivery mode or
temperature settings are adjusted
with the system off, the display
illuminates briefly to show the
settings and then returns to off.
The system can be turned back
on by pressing either
O,D,C,#,
the defrost or the AUTO button.
Driver and Passenger Side
Temperature Controls
The driver and passenger side
temperature buttons are used to
adjust the temperature of the air
coming through the system on
the driver or passenger side of
the vehicle. The temperature can
be adjusted even if the system is
turned off. This is possible since
outside air always flows through
the system as the vehicle is
moving forward unless it is
set to recirculation mode.
See “Recirculation” later in
this section.
Press the + or −buttons to increase
or decrease the cabin temperature.
The driver side or passenger side temperature display shows the
temperature setting increasing or
decreasing.
The passenger temperature
setting can be set to match the
driver temperature setting by
pressing the PASS button and
turning off the PASS indicator.
When the passenger temperature
setting is set different than the driver
setting, the indicator on the PASS
button illuminates and both the
driver side and passenger side
temperature displays are shown.
When in defrost mode the
passenger temperature setting
cannot be changed.

Climate Controls 8-9
The passenger temperature
control cannot be activated while in
defrost mode. If the PASS button is
pressed, the button indicator flashes
three times and will not work. If the
passenger temperature buttons are
adjusted, the driver temperature
indicator changes. The passenger
temperature will not be displayed.
If vent, bi-level, or floor mode is
selected again, the climate control
system displays the previous
temperature settings.
Do not drive the vehicle until all
windows are clear.
#(Air Conditioning):Press
to turn the air conditioning (A/C)
compressor on and off. An indicator
light comes on to show that the air
conditioning is on. If this button is pressed when
the air conditioning compressor
is unavailable due to outside
conditions, the indicator flashes
three times and then turns off.
If the air conditioning is on and the
outside temperature drops below a
temperature which is too cool for air
conditioning to be effective, the air
conditioning light turns off to show
that the air conditioning mode has
been canceled.
On hot days, open the windows long
enough to let hot inside air escape.
This helps to reduce the time it
takes for the vehicle to cool down.
It also helps the system to operate
more efficiently.
The air conditioning system
removes moisture from the air, so
a small amount of water might
drip under the vehicle while idling
or after turning off the engine.
This is normal.
@(Recirculation):
Press
to turn the recirculation mode on.
An indicator light comes on to show
that recirculation is on.
This mode recirculates and helps
to quickly cool the air inside the
vehicle. It can be used to help
prevent outside air and odors
from entering the vehicle.
The recirculation mode cannot
be used with floor, defog, or
defrost modes. If recirculation is
selected with one of those modes,
the indicator light flashes three
times and then turns off. The air
conditioning compressor also comes
on when this mode is activated.
While in recirculation mode, the
windows may fog when the weather
is cold and damp. To clear the fog,
select either the defog or defrost
mode and increase the fan speed.

Climate Controls 8-11
The interior temperature sensor,
located in the headliner, measures
the temperature of the air inside the
vehicle.There is also an exterior
temperature sensor located
behind the front grille. This sensor
reads the outside air temperature
and helps maintain the temperature
inside the vehicle. Any cover on
the front of the vehicle could cause
a false reading in the displayed
temperature.
The climate control system uses
the information from these sensors
to maintain comfort settings by
adjusting the outlet temperature, fan
speed, and the air delivery mode.
The system may also supply cooler
air to the side of the vehicle facing
the sun. The recirculation mode will
also be used as needed to maintain
cool outlet temperatures.
Air Vents
Use the air outlets located in the
center and on the side of the
instrument panel to direct the
airflow. Use the thumbwheels
near the air outlets to open or
close off the airflow.
Operation Tips
.Clear away any ice, snow,
or leaves from air inlets at the
base of the windshield that could
block the flow of air into the
vehicle.
.Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
.Use of non‐GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.

move the pedals closer. Press the
top of the control to move the
pedals away.
Before you start driving, fully
press the brake pedal to confirm
the adjustment is right for you.
While driving, make only small
adjustments.
The vehicle may have a memory
function which lets pedal settings
be saved and recalled. See

more information.
Ignition Positions

positions.
To shift out of P (Park), the
ignition must be in ON/RUN or
