188 Infotainment System
If POI is asked for, say
“Change Location,”then
“Change Country.”
Direct commands might be
more clearly understood by
the system. An example of a
direct command would be “Call
.” Examples of these
direct commands are
displayed on most of the
screens while a voice session
is active. If “Phone”or“Phone
Commands,” is spoken, the
system understands that a
phone call is requested and
will respond with questions
until enough details are
gathered to make a call.
If a cell phone number has
been saved with a name and a
place, the direct command
should include both, for
example “Call
at work.”Using Voice Recognition
for List Options
When a list is displayed, a
voice prompt will ask to
confirm or select an option
from that list.
When a display contains a list,
there may be options that are
available but not displayed.
The list on a voice recognition
screen functions the same as
a list on other displays.
Scrolling or flinging can be
used to help display other
entries from the list.
Manually scrolling or paging
the list on a display during a
voice recognition session
suspends the current voice
recognition event and plays
the prompt “Please select
manually or touch the Back
icon on the infotainment
display to try again.”
If manual selection takes more
than 15 seconds, the session
terminates and prompts that it has timed out. The display
returns to the display where
voice recognition was initiated.
The Back Command
Say
“Back” or touch the Back
icon on the infotainment
display to go to the
previous menu.
If in voice recognition, and
“Back” is spoken all the way
back to the starting display,
and then “Back”is spoken one
more time, the voice
recognition session will cancel.
Help
Say “Help” on any voice
recognition display and the
help prompt for the display is
played.
Voice Recognition for the
Radio
If browsing the audio sources
when voice is touched, the
voice recognition commands
for AM, FM, and SiriusXM (if
equipped) are available.

Handling Large Amounts of
Media Content
It is expected that large
amounts of media content will
be brought into the vehicle.
It may be necessary to handle
large amounts of media
content in a different way than
smaller amounts of media. The
system may limit the options
of voice recognition by not
allowing selection of files by
voice at the highest level if the
number of files exceeds the
maximum limit. Changes to voice commands
due to media content
limits are:
.Files including other
individual files of all media
types such as songs,
audiobook chapters, podcast
episodes, and videos.
.Album type folders including
types such as albums and
audiobooks.
There are no restrictions if the
number of files and albums is
fewer than 12,000. When the
number of files connected to
the system is between
12,000 and 24,000, the
content cannot be accessed
directly with one command like
“Play .”
The restriction is that the
command “Play Song” must be
spoken first; the system will
then ask for the song name.
The reply command would be
to say the name of the song
to play.
