Press on the steering wheel controls

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 <name>
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.
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 <number>.
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
Infotainment 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
<name> 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.
