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 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.
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 LOW
START VEHICLE. If this message
displays, it is recommended that the
driver reduce the electrical loads as
much as possible and restart the
vehicle. See
Battery Voltage and
Charging Messages on page 5‑35.
Battery Power Protection
This feature shuts off the dome, and
reading lamps if they are left on for
more than 10 minutes when the
ignition is off. This will keep the
battery from running down.

.Set up the tone, speaker
adjustments, and preset radio
stations.
For more information, see Defensive
Driving on page 9‑3.
This vehicle's audio system may be
equipped with a noise reduction
system which can work improperly
if the audio amplifier, engine
calibrations, exhaust system,
microphones, radio, or speakers are
modified or replaced. This could
result in more noticeable engine
noise at certain speeds. Notice:
Contact your dealer
before adding any equipment.
Adding audio or communication
equipment could interfere with
the operation of the engine, radio,
or other systems, and could
damage them. Follow federal
rules covering mobile radio and
telephone equipment. The vehicle has Retained
Accessory Power (RAP). With RAP,
the audio system can be played
even after the ignition is turned off.
See
Retained Accessory Power
(RAP) on page 9‑26 for more
information.

Speed Compensated Volume
(SCV): Radios with Speed
Compensated Volume (SCV)
automatically adjusts the radio
volume to compensate for road and
wind noise as the vehicle's speed
changes while driving, so that the
volume level stays consistent.
To activate SCV:
1. Set the radio volume to the desired level.
2. Press the MENU button to display the radio setup menu. 3. Press the softkey under the
AUTO VOLUM (automatic
volume) tab on the radio display.
4. Press the softkey under the desired Speed Compensated
Volume setting (OFF, Low, Med,
or High) to select the level of
radio volume compensation.
The display times out after
approximately 10 seconds. Each
higher setting allows for more
radio volume compensation at
faster vehicle speeds.
Noise Compensation
Technology: Vehicles with the LTZ
package and a Bose Audio System
include the Bose AudioPilot
®noise
compensation technology. When
turned on, AudioPilot continuously
adjusts the audio system
equalization, to compensate for
background noise, so that music
always sounds the same at the set
volume level. This feature is most effective at
lower radio volume settings where
background noise can affect how
well the music is heard. At higher
volume settings, where the music is
much louder than the background
noise, there might be little or no
adjustments by AudioPilot.
To activate:
1. Set the radio volume to the
desired level.
2. Press the MENU button to display the radio setup menu.
3. Press the softkey under the AUTO VOLUM (automatic
volume) tab on the radio display.
4. Press the softkey under the ON tab. The display times out after
approximately 10 seconds.
