2009 GMC SIERRA 1500 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, or LOW BATTERY. If this
message is displayed, it is recommended that the driver
reduce the electrical loads as much as possible. SeeDIC
Warnings and Messages on page 3-66.
Battery Run-Down Protection
This feature shuts off the dome and reading lamps, if they
are left on for more than 10 minutes after the ignition is
turned off. The cargo lamp shuts off after 20 minutes.
This prevents 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.
The vehicle may have two accessory power outlets
located below the climate control system, or may have
one accessory power outlet and one cigarette lighter.
The cigarette lighter is designed to t only in the
receptacle closest to the driver.
There may be another accessory power outlet in the
rear cargo area. If the vehicle has a oor console, there
is an accessory power outlet inside the storage bin
and one on the rear of the oor console.
To use an accessory power outlet, remove the protective
cap. When not in use, always cover the accessory power
outlet with the protective cap.
Notice:Leaving electrical equipment plugged in for
an extended period of time while the vehicle is off
will drain the battery. Power is always supplied
to the outlets. Always unplug electrical equipment
when not in use and do not plug in equipment
that exceeds the maximum 20 ampere rating.

with the system off, the display illuminates briey 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’s side of the
vehicle. The temperature can be adjusted even if the
system is turned off. This is possible since outside air
always ows 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.
3-27

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.
Automatic Operation
AUTO (Automatic):When automatic operation is active
the system controls 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 changes to
show the current temperature(s) and AUTO is lit on
the display. The current air delivery mode and fan
speed are also displayed for about 5 seconds.
When AUTO is selected, the air conditioning
operation and air inlet are automatically controlled.
The air conditioning compressor may run when the
outside temperature is above freezing. The air inlet
will normally be set to outside air. If it is hot outside,
the air inlet may automatically switch to the
recirculate mode to help quickly cool down the air
inside the vehicle. The light on the button comes on
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. Use the driver or passenger
temperature buttons to adjust the temperature setting
as necessary. If a temperature setting of 60°F (15°C)
is chosen, the system remains at the maximum
cooling setting. If a temperature setting of 90°F
(32°C) 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 cover the solar sensor located on the top of the
instrument panel near the windshield. This sensor
regulates air temperature based on sun load. For more
information on the solar sensor, see “Sensors” later in
this section.
To avoid blowing cold air in cold weather, the system
delays turning the fan on until warm air is available.
The length of delay depends on the engine coolant
temperature. Pressing the fan switch overrides this
delay and changes the fan to a selected speed.

Manual Operation
DC(Fan Control):Press these buttons to increase or
decrease the fan speed.
Pressing either fan button while in automatic control
places the fan under manual control. The fan setting
remains displayed and the AUTO light turns off. The air
delivery mode remains under automatic control.
HG(Air Delivery Mode Control):Press these buttons
to change the direction of the airow in the vehicle.
Repeatedly press either button until the desired mode
appears on the display. Pressing either mode button
while the system is off changes the air delivery mode
without turning the system on. Pressing either mode
button while in automatic control places the mode under
manual control.
The air delivery mode setting is displayed and the AUTO
light turns off. The fan remains under automatic control.
H(Vent):Air is directed to the instrument panel
outlets.
)(Bi-Level):Air is divided between the instrument
panel and oor outlets. Some air is directed towards the
windshield and side window outlets.
6(Floor):Air is directed to the oor outlets, with
some to the windshield, side window outlets, and second
row oor 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, oor 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
defrost mode.

Sensors
The solar sensor, located in the defrost grille, in the
middle of the instrument panel, monitors the solar heat.
Do not cover the solar sensor or the system will not work
properly.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 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.

Speedometer and Odometer
The speedometer shows the vehicle speed in both miles
per hour (mph) and kilometers per hour (km/h). The
odometer shows how far the vehicle has been driven, in
either miles (used in the United States) or kilometers
(used in Canada).
Engine Hour Meter Display
The Driver Information Center (DIC) can also display
the number of hours the engine has run. To display
the engine hours, turn the ignition off, press and hold the
reset button for at least four seconds. The hour meter
displays for up to 30 seconds, or until the ignition is
turned on. SeeDIC Operation and Displays (With DIC
Buttons) on page 3-53orDIC Operation and Displays
(Without DIC Buttons) on page 3-59for more
information.
Trip Odometer
The trip odometer shows how far the vehicle has been
driven since the trip odometer was last set to zero.
Press the reset button, located on the instrument panel
cluster next to the voltmeter, to toggle between the trip
odometer and the regular odometer. Holding the reset
button for approximately one second while the trip
odometer is displayed will reset it.
To display the odometer reading with the ignition off,
press the reset button.
SeeDIC Operation and Displays (With DIC Buttons) on
page 3-53orDIC Operation and Displays (Without
DIC Buttons) on page 3-59for more information.
Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm). For a description of how Grade Braking
affects vehicle speed while the Tow/Haul Mode is
activated, see “Grade Braking (Allison Transmission
®)”
underTow/Haul Mode on page 2-34for more information.

Here are some situations owners can experience with
the fuel gage. None of these indicate a problem with the
fuel gage.
At the gas station, the fuel pump shuts off before
the gage reads full.
It takes a little more or less fuel to ll up than the
fuel gage indicated. For example, the gage may
have indicated the tank was half full, but it actually
took a little more or less than half the fuel tank’s
capacity to ll it.
The gage goes back to empty when the ignition is
turned off.
For a diesel engine, see “Fuel Gage” in the Diesel
Engine Supplement.
Low Fuel Warning Light
This light, under the fuel
gage, comes on briey
while the engine is being
started.
This light and a chime comes on when the fuel tank is low
on fuel. The Driver Information Center also displays a
“FUEL LEVEL LOW” message. SeeDIC Warnings and
Messages on page 3-66for more information. When fuel
is added this light and message should go off. If it does
not, have the vehicle serviced by your dealer/retailer.
