incorrect information that
causes the radio features to
work improperly. If this
happens, contact the radio
station.

SiriusXM Radio Service
If equipped, vehicles with a
valid SiriusXM radio
subscription can receive
SiriusXM programming.
SiriusXM radio has a wide
variety of programming and
commercial-free music, coast
to coast, in digital-quality
sound. In the U.S., see
www.siriusxm.com or call
1-888-601-6296. In Canada,

SiriusXM with 360L
SiriusXM with 360L interface

and system learned
recommendations toward
discovering more personalized
content.
To use the full SiriusXM 360L
program, including streaming
content and listening
recommendations, OnStar
Connected Access is required.
Connected vehicle services
vary by model and require a
complete working electrical
system, cell reception, and
GPS signal. An active
connected plan is required.
Reference the SiriusXM user
guide for use and subscription
information.
Radio Reception
Unplug electronic devices
from the accessory power
outlets if there is interference
or static in the radio.
FM
FM signals only reach about 16
to 65 km (10 to 40 mi).
Although the radio has a
built-in electronic circuit that
automatically works to reduce
interference, some static can
occur, especially around tall
buildings or hills, causing the
sound to fade in and out.
AM
The range for most AM
stations is greater than for
FM, especially at night. The
longer range can cause station
frequencies to interfere with
each other. Static can also
occur when things like storms
and power lines interfere with
radio reception. When this
happens, try reducing the
treble on the radio.

bridges, garages, or tunnels
may cause loss of the
SiriusXM signal for a period of
time. Some cellular services
may interfere with SXM
reception causing loss of
signal.
Mobile Device Usage
Mobile device usage, such as
making or receiving calls,
charging, or just having the

or the session is terminated,
the voice recognition dialog
stops.
An example of this type of
manual intervention is
touching an entry of a
displayed number list instead
of speaking the number
associated with the entry
desired.
Canceling Voice
Recognition
.Touch or say“Cancel”or
“Exit” to terminate the voice
recognition session and
show the display where
voice recognition was
initiated.
.Pression the steering
wheel controls to terminate
the voice recognition
session and show the display
where voice recognition was
initiated.
Natural Language Commands
Most languages do not
support natural language
commands in sentence form. For those languages, use
direct commands like the
examples shown on the
display.
Helpful Hints for Speaking
Commands
Voice recognition can
understand commands that
are naturally stated in
sentence form or direct
commands that state the
application and the task.
For best results:
.Listen for the prompt before
saying a command or reply.
.Speak the command
naturally, not too fast, not
too slow.
.Use direct commands
without a lot of extra words.
For example,
“Call at
work,” “Play” followed by the
artist or song name,
or “Tune” followed by the
radio station number.
.Navigation destinations can
be made in a single
command using keywords. A few examples are:
“I want
directions to an address,” “I
need to find a place of
interest or (POI),” or“Find
contact.”
The system responds by
requesting more details. For
other POIs, say the name of
a category like
“Restaurants,” “Shopping
Malls,” or“Hospitals.”
.Navigating to a destination
outside of the current
country takes more than one
command. The first
command is to tell the
system where the navigation
will take place, such as an
Address, Intersection, POI,
or Contact. If Address or
Intersection is selected, the
second command is to say,
“Change Country.” Once the
system responds, say the
country before saying the
rest of the address and/or
intersection.

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.
