Lighting Features
Entry Lighting
Some exterior lamps and the interior
lamps turn on briefly at night, or in
areas with limited lighting, when
K
is pressed on the Remote Keyless
Entry (RKE) transmitter. When a
door is opened, the interior lamps
come on if the dome lamp control is
in the DOOR position. After about
30 seconds the exterior lamps turn
off. Entry lighting can be disabled
manually by changing the ignition
out of the OFF position, or by
pressing the RKE transmitter
Q
button.
This feature can be changed. See
“Vehicle Locator Lights”under
Vehicle Personalization 0164.
Exit Lighting
Some exterior lamps and interior
lamps come on when the key is
removed from the ignition. The
exterior and interior lamps remain
on for a set amount of time, then
automatically turn off. If equipped with Keyless Access,
the exterior lamps automatically turn
on when the driver
’s door is opened
after the ignition is turned to OFF.
The interior lights turn on when the
ignition is turned to OFF.
The exterior lamps turn off
immediately by turning the exterior
lamp control off.
This feature can be changed. See
Vehicle Personalization 0164.
Battery Load
Management
The vehicle has Electric Power
Management (EPM), which
estimates the battery's temperature
and state of charge. It then adjusts
the voltage for best performance
and extended life of the battery.
When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. The voltmeter
gauge or the voltage display on the
Driver Information Center (DIC), if equipped, may show the voltage
moving up or down. This is normal.
If there is a problem, an alert will be
displayed.
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.

.
Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
could block the flow of air into
the vehicle.
. 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 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.
