Battery Load
Management
The vehicle has Electric Power
Management (EPM) that
estimates the battery
temperature and state of
charge. It then adjusts the
voltage for best performance
and extended life of the 12–
volt battery
When the battery state of
charge is low, the voltage is
raised slightly to quickly
increase the charge. When thestate of charge is high, the
voltage is lowered slightly to
prevent over charging. As this
adjustment occurs, you may
see the voltage move up or
down on the voltmeter gauge
or voltage display on the
Driver Information (DIC),
if equipped. This is normal. If a
problem occurs, an alert will be
displayed.
If the electrical loads are very
high, the battery can be
discharged when the vehicle is
stationary. A high electrical
load occurs when several
features are on, such as:
headlamps, high beams, rear
window defogger, climate
control fan at high speed,
heated seats, motor cooling
fans, trailer loads, and loads
plugged into accessory power
outlets.
EPM works to prevent
excessive discharge of the
battery by balancing the
electrical system output and
the vehicle's electrical needs.

covered by the vehicle
warranty.
Sensor
The solar sensor, on top of the
instrument panel near the
windshield, monitors the
solar heat.The climate control system
uses the sensor information to
adjust the temperature, fan
speed, recirculation, and air
delivery mode for best
comfort.
If the sensor is covered, the

system may not work properly.
Remote Start Climate
Control Operation :
The
climate control system may
run when the vehicle is started
remotely. The system uses the
driver’s previous settings to
heat or cool the inside of the
vehicle. The rear defog may
come on during remote start
based on cold ambient
conditions. The rear defog
indicator light does not come
on during a remote start.
If equipped with heated or
cooled seats, they may come
on during a remote start. See
Remote Start 015 and
Heated and Ventilated Front
Seats 045. Afterblow Feature
If equipped, under certain
conditions, the fan may stay
on or may turn on and off
several times after you turn
off and lock the vehicle. This is
normal.
Air Vents
Use the multi-function joystick
control on the front center
and side air vents to change
the direction of the airflow.
Air vents blow warm air on the
side windows in cold weather.
If floor, defog, or defrost
modes are selected, a small
amount of air will come from
the vents close to the window.
To fully open the front A/C
vents, turn the multi-function
joystick control knob until the
indicator points straight up.
To close the front A/C vents,
turn the multi-function joystick
control until the indicator
points to the nine o'clock

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.
.Clear snow off the hood to
improve visibility and help
decrease moisture drawn
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.
.Do not attach any devices to
the air vent slats. This will
restrict airflow and may
cause damage to the air
vents.
