Introduction
Read the following pages to become familiar
with the features.
{Warning
Taking your eyes off the road for too
long or too often while using any
infotainment feature can cause a crash.
You or others could be injured or killed.
Do not give extended attention to
infotainment tasks while driving. Limit
your glances at the vehicle displays and
focus your attention on driving. Use voice
commands whenever possible.
The infotainment system has built-in
features intended to help avoid distraction
by disabling some features when driving.
These features 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,
center stack controls, steering wheel
controls, and infotainment display.

14400528) - 2021 - CRC - 11/7/19
Infotainment System 147
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 touches, such as 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 touching one or two options,
and are not supported by voice commands.
In general there are flexible ways to speak
commands for completing the tasks.
If your language supports it, try stating a
one-shot command, such as“Directions to
address
while stating the address during the
command. Another example of a one-shot
Destination Entry command is, “Directions to
Place of Interest at
commands do not work, try saying, “Take
me to Place of Interest” or“Find address”
and the system will walk you through by
asking additional questions.Hybrid Speech Recognition
If equipped, this feature helps distinguish
words by using Internet-based information
along with the system’s voice recognition
database. This allows you to speak more
naturally when using voice recognition.
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 controls
to activate voice recognition.
2. The audio system mutes and the system plays a prompt.
3. Clearly speak one of the commands described in this section.
A voice recognition system prompt can
be interrupted while it is playing by
pressing
gagain.
Once voice recognition is started, both the
infotainment display and instrument cluster
show the selections and visual dialog
content. These displays can be turned on or
off in the Tutorial Mode under Settings
0 157. There are three voice prompt modes
supported:
.Informative verbal prompts: This type of
prompt will provide more information
regarding the supported actions.
.Short prompts: This type of prompt will
provide simple instructions about what
can be stated.
.Auto informative prompts: This type of
prompt plays during the first few speech
sessions, then automatically switches to
the short prompt after some experience
has been gained through using the
system.
If a command is not spoken, the voice
recognition system says a help prompt.
Prompts and Infotainment Displays
While a voice recognition session is active,
there may be corresponding options
showing on the displays. A selection can be
made by manually touching the option,
or by speaking the number for the option to
select. Manual interaction in the voice
recognition session is permitted. Interaction
during a voice session may be completed
entirely using voice commands while some
manual commands may expedite a task. If a
selection is made using a manual control,

wheel brakes to assist the driver in keeping
the vehicle on the intended path.
If cruise control is being used and TCS or
StabiliTrak/ESC begins to limit wheel spin,
cruise control will disengage. Cruise control
may be turned back on when road
conditions allow.
Both systems come on automatically when
the vehicle is started and begins to move.
The systems may be heard or felt while
they are operating or while performing
diagnostic checks. This is normal and does
not mean there is a problem with the
vehicle.
It is recommended to leave both systems on
for normal driving conditions, but it may be
necessary to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow. SeeIf the
Vehicle Is Stuck 0187 and “Turning the

instrument cluster. This light will:
.Flash when TCS is limiting wheel spin.
.Flash when StabiliTrak/ESC is activated.
.Turn on and stay on when either system
is not working.
If either system fails to turn on or to
activate, a message displays in the Driver
Information Center (DIC), and
dcomes on
and stays on to indicate that the system is
inactive and is not assisting the driver in
maintaining control. The vehicle is safe to
drive, but driving should be adjusted
accordingly.
If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.

release to override cruise control, briefly
pressing −SET will result in cruise control set
to the current vehicle speed. Using Cruise Control on Hills
How well the cruise control works on hills
depends upon the vehicle speed, load, and
the steepness of the hills. When going up
steep hills, you might have to step on the
accelerator pedal to maintain the vehicle
speed. When going downhill, you might
have to brake or shift to a lower gear to
keep your speed down. If the brake pedal is
applied, cruise control will disengage.
Ending Cruise Control
There are four ways to end cruise control:
.Step lightly on the brake pedal.
.Press*.
.Shift the transmission to N (Neutral).
.To turn off cruise control, press5.
Erasing Speed Memory
The cruise control set speed is erased from
memory if
5is pressed or if the ignition is
turned off.
Adaptive Cruise Control (Camera)
If equipped, Adaptive Cruise Control (ACC)
allows the cruise control set speed and
following gap to be selected. Read this
entire section before using this system. The following gap is the following time between
your vehicle and a vehicle detected directly
ahead in your path, moving in the same
direction. If no vehicle is detected in your
path, ACC works like regular cruise control.
ACC uses a windshield mounted front
camera sensor.
If a vehicle is detected in your path, ACC can
apply acceleration or limited, moderate
braking to maintain the selected following
gap. To disengage ACC, apply the brake.
If ACC is controlling the vehicle speed when
the Traction Control System (TCS) or
StabiliTrak/ Electronic Stability Control (ESC)
system activates, ACC may automatically
disengage. See
Traction Control/Electronic
Stability Control 0206. When road
conditions allow ACC to be safely used, ACC
can be turned back on. Disabling the TCS or
StabiliTrak/ ESC system will disengage and
prevent engagement of ACC.
ACC can reduce the need for you to
frequently brake and accelerate, especially
when used on expressways, freeways, and
interstate highways. When used on other
roads, you may need to take over the
control of braking or acceleration more
often.
