Vehicle Personalization on

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.

Lighting 6-9
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 DIC message might
be displayed and it is recommended
that the driver reduce the electrical
loads as much as possible. See
Battery Voltage and Charging
Messages on page 5-36.Battery Power Protection
This feature shuts off the dome and
reading lamps, if they are left on for
more than 10 minutes after the
ignition is turned off. The cargo
lamp shuts off after 20 minutes. This
prevents the battery from
running down.

7-2 Infotainment System
The infotainment system has built-in
features intended to help avoid
distraction by disabling some
functions when driving. These
functions may gray out when they
are unavailable. Many infotainment
features are also available through
the instrument cluster and steering
wheel controls.
Before driving:
.Become familiar with the
operation, faceplate buttons, and
screen buttons.
.Set up the audio by presetting
favorite stations, setting the
tone, and adjusting the
speakers.
.Set up phone numbers in
advance so they can be called
easily by pressing a single
button or by using a single voice
command if equipped with
Bluetooth phone capability.
See Defensive Driving on page 9-3.
To play the infotainment system with
the ignition off, see Retained
Accessory Power (RAP) on
page 9-28.
Theft-Deterrent Feature
TheftLock®is designed to
discourage theft of the vehicle's
radio by learning a portion of the
Vehicle Identification Number (VIN).
The radio does not operate if it is
stolen or moved to a different
vehicle.

Voice Recognition
If equipped, voice recognition allows
for hands-free operation within the
audio and phone applications. This
feature can be started by pressing
either the
gbutton on the steering
wheel or by selecting the
gon the
screen display.
However, not all features within
these areas are supported by voice
commands. Generally, only complex
tasks that require multiple manual
interactions to complete are
supported by voice commands.
For example, tasks that take more
than one or two button presses such
as selecting a song or artist to play
from a media device would be
supported by voice commands.
Other tasks, like adjusting the
volume or seeking up or down are audio features that are easily
performed by pressing one or two
buttons, and are not supported by
voice commands.
In general there are flexible ways to
speak commands for completing the
tasks. Most of them, except
destination entry and voice keypad,
can be completed in a single
command. If the task takes more
than one command to complete, the
first command would be to indicate
the kind of task that is to be
performed. The system replies with
prompts that lead through a dialog
to enter the necessary information.
Voice recognition can be used when
the ignition is on or when Retained
Accessory Power (RAP) is active.
See
Retained Accessory Power
(RAP) on page 9-28.

Infotainment System 7-25
Using Voice Recognition
Voice recognition becomes available
once the system has been
initialized. This begins when the
ignition is turned on. Initialization
may take a few moments.
1. Press
gon the steering wheel
control to activate voice
recognition, or select
gon the
infotainment screen on the
center stack.
.If voice recognition is
started from the steering
wheel control, the
instrument cluster displays
the selections and visual
dialog content.
.If voice recognition is
started from the
infotainment screen, the
selections and visual dialog
content are displayed on
both the center stack
display and the instrument
cluster display. 2. The audio system mutes and the
system plays a prompt followed
by a beep.
3. Wait until after the beep completes, then clearly speak
one of the commands described
in this section.
Press
gto interrupt any voice
recognition system prompt. For
example, if the prompt seems to
be taking too long to finish,
press
gagain and the beep
should happen right away.
There are two voice prompt modes
supported:
.Long verbal prompts: The longer
prompts provide more
information regarding the
supported actions.
.Short prompts: The short
prompts provide simple
instructions about what can be
stated. If a command is not spoken, the
voice recognition system says a
help prompt.
Prompts and Screen Displays
While a voice recognition session is
active, there will be corresponding
buttons on screens displayed.
Manual interaction in the voice
recognition session is permitted.
Interaction during a voice session
may be completed entirely using
voice commands, or some
selections may expedite a session.
If a selection is made using a
manual control, the dialog will
progress in the same way as if the
selection was made through a voice
command. Once the system is able
to complete the task, or the session
is terminated, the voice recognition
dialog stops.
An example of this type of manual
intervention is pressing on an entry
of a displayed number list instead of
speaking the number associated
with the entry desired.
