The vehicle must have a working electrical system,
including adequate battery power, for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service at any particular time or place. Some
examples are damage to important parts of the vehicle
in a crash, hills, tall buildings, tunnels, weather or
wireless phone network congestion.

Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left on,
the exterior lamps will turn off about 10 minutes after the
ignition is turned off. This protects against draining the
battery in case you have accidentally left the headlamps
or parking lamps on. The battery saver does not work
if the headlamps are turned on after the ignition is
turned off.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn
the lamps back on.
Instrument Panel Brightness
Press the center knob on
the DIC control panel to
extend. Then turn the knob
clockwise to brighten the
lights or counterclockwise
to dim them. If the knob
is turned completely
clockwise, the interior
lamps turn on.

Entry Lighting
The entry lighting system turns on the reading and
dome lamps and the backlighting to the exterior lamp
control when a door is opened or if you press the remote
keyless entry transmitter unlock button. If activated by
the transmitter, the lighting will remain active for about
25 seconds. The entry lighting system uses the light
sensor; it must be dark outside in order for the lamps to
turn on. The lamps turn off about 25 seconds after the
last door is closed. They will dim to off if the ignition is
on, or immediately deactivate if the power locks are
activated.
Parade Dimming
This feature prohibits dimming of the instrument panel
displays and backlighting during daylight hours when
the key is in the ignition and the headlamps are on.
This feature operates with the light sensor and is fully
automatic. When the light sensor reads darkness outside
and the parking lamps are active, the instrument panel
displays can be adjusted by turning the instrument panel
brightness knob. SeeInstrument Panel Brightness on
page 3-40for additional information.
Reading Lamps
The reading lamps are located on the overhead console.
These lamps come on automatically when any door is
opened.
For manual operation, press the button next to each
lamp to turn it on or off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher revolutions per minute (rpm) setting than normal to
make sure the battery charges. High electrical loads may
occur when several of the following are on: headlamps,
high beams, fog lamps, rear window defogger, the
climate control fan at high speeds, heated seats and
engine cooling fans.
If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer to clear
the glass and the fan may cut back to a lower speed.
For more battery saving information, see “Battery Saver
Active Message” underDIC Warnings and Messages on
page 3-79.
3-41

Electric Power 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
gage 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 the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following are on: 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.
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 or
Service Battery Charging System. 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 3-79.
Inadvertent Power Battery Saver
This feature is designed to protect the vehicle’s battery
against drainage from the interior lamps, trunk lamp,
glove box lamp, or the garage door opener. When the
ignition is turned off, the power to these features will
automatically turn off after 10 minutes (three minutes
if a new car has 15 miles (24 km) or less). Power will
be restored for an additional 10 minutes if any door
is opened, the trunk is opened or the courtesy lamp
switch is turned on.

PEDAL APPLIED ACC OVERRIDE
When the PEDAL APPLIED ACC OVERRIDE message
displays, the accelerator pedal is being pressed and
the Adaptive Cruise Control is overridden and cannot
automatically apply the brakes. Once the accelerator
pedal is released, the Adaptive Cruise Control will return
to normal operation and be able to apply the brakes,
if needed.
An Adaptive Cruise Control active symbol, alert symbol
or vehicle ahead symbol may also appear. SeeAdaptive
Cruise Control on page 3-20for more information.
Care of the HUD
Clean the inside of the windshield as needed to remove
any dirt or lm that reduces the sharpness or clarity
of the HUD display.
To clean the HUD, spray household glass cleaner on a
soft, clean cloth. Wipe the HUD lens gently, then dry.
Notice:When cleaning, be careful not to scratch
the HUD or camera lenses. Do not spray glass
cleaner directly on the HUD lens because the cleaner
could leak inside the unit and cause damage.
Accessory Power Outlet(s)
Accessory power outlets can be used to plug in electrical
equipment, such as a cellular telephone.
The vehicle has one outlet in front of the center console,
one in the center console lid and there may be an
additional outlet in the rear of the center console.
The vehicle may have a small cap that must be
removed to access the accessory power outlet.
Be sure to cover the outlet with the protective cap
when it is not in use.
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.
Certain accessory power plugs may not be compatible
to the accessory power outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information
on the accessory power outlets.
Notice:Adding any electrical equipment to the
vehicle can damage it or keep other components
from working as they should. The repairs would
not be covered by the vehicle warranty. Do not
