Lighting 149
Lighting Features
Entry Lighting
Some exterior lamps and most of
the interior lamps turn on briefly at
night or in areas with limited lighting
when the Remote Keyless Entry
(RKE) transmitter
Kbutton is
pressed. See Remote Keyless Entry
(RKE) System Operation 028. After
about 30 seconds the exterior lamps
turn off, then the dome lamps and
remaining interior lamps dim to off.
Entry lighting can be disabled
manually by turning the ignition on
or to ACC/ACCESSORY, or by
pressing
Qon the RKE transmitter.
This feature can be changed. See
Vehicle Personalization 0132.
Exit Lighting
Some exterior lamps and interior
lights come on at night, or in areas
with limited lighting, when the driver
door is opened after the ignition is
turned off. The dome lamp comes
on after the ignition is turned off. The exterior lamps and dome lamp
remain on for a set amount of time,
then automatically turn off.
The exterior lamps turn off
immediately by turning the exterior
lamp control off.
This feature can be changed. See
Vehicle Personalization
0132.
Battery Load
Management
The vehicle has Electric Power
Management (EPM) that 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. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the voltage move 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 of the
power needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, 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.

158 Climate Controls
on, see“Climate and Air Quality”
under Vehicle Personalization
0 132.
Rear Window Defogger
K:Press to turn the rear window
defogger on or off. An indicator light
on the button comes on to show that
the rear window defogger is on.
The upper region of gridlines on the
rear window are antenna lines and
are not intended to heat when the
defogger is activated.
If equipped with heated outside
mirrors, they turn on with the rear
window defogger and help to clear
fog or frost from the surface of the
mirror. See Heated Mirrors 044.
Caution
Using a razor blade or sharp
object on the inside rear window
can damage the antenna or
defogger. Repairs would not be
covered by the vehicle warranty.
Do not stick anything to the rear
window. Remote Start Climate Control
Operation :
If equipped with remote
start, 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 may not come on during a
remote start. The front heated seats
may turn on if it is cold outside. The
heated seat indicator lights may not
come on during a remote start.
See Remote Vehicle Start 034 and
Heated and Ventilated Front Seats
0 60, if equipped.
Sensors
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
automatic climate control system
may not work properly.

194 Driving and Operating
Stationary or Very Slow-Moving
Objects
{Warning
ACC may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system may not brake for a
vehicle it has never detected
moving. This can occur in
stop-and-go traffic or when a
vehicle suddenly appears due to
a vehicle ahead changing lanes.
Your vehicle may not stop and
could cause a crash. Use caution
when using ACC. Your complete
attention is always required while
driving and you should be ready
to take action and apply the
brakes.
ACC Automatically Disengages
ACC may automatically disengage
and the driver will need to manually
apply the brakes to slow the
vehicle if:
. The sensors are blocked. .
The Traction Control System
(TCS) or StabiliTrak/ESC system
has activated or been disabled.
. There is a fault in the system.
. The radar falsely reports
blockage when driving in a
desert or remote area with no
other vehicles or roadside
objects. A DIC message may
display to indicate that ACC is
temporarily unavailable.
A message indicating that the cruise
is disengaging will appear on the
DIC and the ACC active symbol will
not be displayed when ACC is no
longer active.
Notification to Resume ACC
ACC will maintain a following gap
behind a detected vehicle and slow
your vehicle to a stop behind that
vehicle.
If the stopped vehicle ahead has
driven away and ACC has not been
resumed, the vehicle ahead symbol
will flash as a reminder to check
traffic ahead before proceeding. In
addition, three beeps will sound. See
“Adaptive Cruise Go Notifier”
under “Collision/Detection Systems”
in Vehicle Personalization 0132.
When the vehicle ahead drives
away, press +RES or the
accelerator pedal to resume cruise
control. If stopped for more than
two minutes or if the driver door is
opened, the ACC automatically
applies the Electric Parking Brake
(EPB) to hold the vehicle. The EPB
status light will turn on. See Electric
Parking Brake 0184. To resume
ACC and release the EPB, press
the accelerator pedal. ACC can be
resumed when the vehicle is
travelling greater than 25 km/h
(16 mph).
A DIC warning message may
display indicating to shift to P (Park)
before exiting the vehicle. See
Vehicle Messages 0131.

California Perchlorate
Materials Requirements
Certain types of automotive
applications, such as airbag
initiators, seat belt pretensioners,
and lithium batteries contained in
Remote Keyless Entry transmitters,
may contain perchlorate materials.
Special handling may be necessary.
For additional information, see
www.dtsc.ca.gov/hazardouswaste/

Accessories and
Modifications
Adding non-dealer accessories or
making modifications to the vehicle
can affect vehicle performance and
safety, including such things as
airbags, braking, stability, ride and
handling, emissions systems,
aerodynamics, durability, and
electronic systems like antilock
brakes, traction control, and stability
control. These accessories or
modifications could even cause
malfunction or damage not covered
by the vehicle warranty.Damage to suspension components
caused by modifying vehicle height
outside of factory settings will not be
covered by the vehicle warranty.
Damage to vehicle components
resulting from modifications or the
installation or use of non-GM
certified parts, including control
module or software modifications, is
not covered under the terms of the
vehicle warranty and may affect
remaining warranty coverage for
affected parts.
GM Accessories are designed to
complement and function with other
systems on the vehicle. See your
dealer to accessorize the vehicle
using genuine GM Accessories
installed by a dealer technician.

your vehicle if you do not have
the proper knowledge, service
manual, tools, or parts. Always
follow owner ’s manual procedures
and consult the service manual
for your vehicle before doing any
service work.
If doing some of your own service
work, use the proper service
manual. It tells you much more
about how to service the vehicle
than this manual can. To order the
proper service manual, see
Publication Ordering Information
0 324.
This vehicle has an airbag system.
Before attempting to do your own
service work, see Servicing the
