2010 GMC YUKON XL display

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, BATTERY VOLTAGE LOW, orLOW BATTERY. If this message is displayed, it is
recommended that the driver reduce the electrical
loads as much as possible. See DIC Warnings and
Messages on page 4‑61.
Battery Run-Down Protection
This feature shuts off the dome, and reading lamps
if they are left on for more than 10 minutes when
the ignition is off. This will keep the battery from
running down.
Accessory Power Outlet(s)
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone.
There are two under the climate controls, one inside the
center floor console, one on the rear of the center floor
console and one accessory power outlet in the rear
cargo area on the passenger side.
To use an accessory power outlet, remove the
protective cap. When not in use, always cover the
accessory power outlet with the protective cap.
The accessory power outlets are powered, even with
the ignition off. Continuing to use accessory power
outlets while the ignition is in LOCK/OFF may cause
the vehicle's battery to run down.
Notice: If electrical devices are left plugged into
a power outlet, the battery may drain causing the
vehicle not to start or damage to the battery.
This would not be covered by the vehicle warranty.
Always unplug all electrical devices when turning
off the vehicle.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear Window Defogger):Press this button to
turn the rear window defogger on or off. The system
automatically turns off several minutes after it has been
activated. The defogger can also be turned off by
turning off the engine. Do not drive the vehicle until
all the windows are clear.
For vehicles with heated outside rearview mirrors,
the mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog button
is pressed.
Notice: Do not use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs would not be
covered by the vehicle warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.
Dual Automatic Climate Control

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
Control
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's 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
decreasing or increasing.
The passenger's temperature setting can be set to
match the driver's temperature setting by pressing the
PASS button and turning off the PASS indicator. When
the passenger's temperature setting is set different than
the driver's 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.

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 temperature(s) and AUTO will be
lit on the display. The current delivery mode and
fan speed will also be displayed for approximately
5 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 4°C (40°F). The air inlet will normally be
set to outside air. If it is hot outside, the air inlet
may automatically switch to recirculate inside air
to help quickly cool down the vehicle. The light on
the button comes on in recirculation. 2. Set the driver's and passenger's temperature.
To find your comfort setting, start with a 23°C
(74°F) temperature setting and allow about
20 minutes for the system to regulate. Use the
driver's or passenger's temperature buttons to
adjust the temperature setting as necessary. If a
temperature setting of 15°C (60°F) is chosen, the
system remains at the maximum cooling setting.
If a temperature setting of 32°C (90°F) is chosen,
the system remains at the maximum heat setting.
Choosing either maximum setting will not cause
the vehicle to heat or cool any faster.
Do not to cover the solar 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 the headlamps. For more information on the
solar sensor, see “Sensors”later in this section.
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.

panel and floor outlets. Some air is directed towards the
windshield and side window outlets.
6(Floor): Air is directed to the floor outlets, with some
to the windshield, side window outlets, and second row
floor outlets. In this mode, the system automatically
selects outside air.
-(Defog): This mode clears the windows of fog or
moisture. Air is directed to the windshield, floor outlets,
and side window vents. In this mode, the system
turns off recirculation and runs the air conditioning
compressor unless the outside temperature is close
to freezing. The recirculation mode cannot be selected
while in the defog mode.
0(Defrost): This mode removes fog or frost from
the windshield more quickly. Air is directed to the
windshield and side window vents, with some
directed to the floor vents. In this mode, the system
automatically forces outside air into the vehicle and
runs the air conditioning compressor unless the outside
temperature is close to freezing. The recirculation mode
cannot be selected while in the defrost mode.
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 the windows are clear.

The interior temperature sensors located in the
headliner above the driver side seat and if equipped, in
the headliner above the second row seats measure 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 your comfort setting 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.
Outlet Adjustment
Use the air outlets located in the center and on the side
of the instrument panel to direct the airflow.
Operation Tips
.Keep the hood and front air inlets free of ice,
snow, or any other obstruction (such as leaves).
The heater and defroster will work far better,
reducing the chance of fogging the inside of the
windows.
.When you enter a vehicle in cold weather, press
the fan up button to the maximum fan level before
driving. This helps clear the intake ducts of snow
and moisture, and reduces the chance of fogging
the inside of the window.
.Keep the air path under the front seats clear of
objects. This helps air to circulate throughout the
vehicle.
.Adding outside equipment to the front of the
vehicle, such as hood-air deflectors, may affect the
performance of the heating and air conditioning
system. Check with your dealer before adding
equipment to the outside of the vehicle.

Warning Lights, Gauges, and
Indicators
Warning lights and gauges can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to the
warning lights and gauges could prevent injury.
Warning lights come on when there might be or there
is a problem with one of the vehicle's functions. Some
warning lights come on briefly when the engine is
started to indicate they are working.
Gauges can indicate when there might be or there is
a problem with one of the vehicle's functions. Often
gauges and warning lights work together to indicate
a problem with the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gauges shows there
could be a problem, check the section that explains
what to do. Follow this manual's advice. Waiting to do
repairs can be costly and even dangerous.
