Voice Control
You can perform telephone, audio, 
navigation, and other operations by voice 
command.
There are two types of voice control 
functions: the function from this product 
and the function used in a Bluetooth 
® 2.0 
interface.
1Press the “SPEECH” key on 
the steering wheel. After you 
hear the “beep”, say “Voice 
commands”.
→“Steering Remote Control Switch  Operation”(P82)
The telop and guide screen is displayed. 
When speaking, use the details displayed 
on the guide screen as reference.
ADVICE
•  You can check the usage for voice 
control, a list of voice commands, etc. 
→ “Check the Voice Control Help” (P194)
• The voice control function cannot be 
used right after the navigation starts up. 
Please wait for a while before using.
•  Depending on the status of the 
navigation, voice control may not be 
possible.
•  Depending on the combination of devices 
and modes, voice commands may not be 
recognized.
•  The guide screen will be displayed while 
the vehicle is moving. You can choose 
to not display the guide screen. 
→“Voice 
control settings” (P212)
•  If you use other functions during voice 
command (including during phone 
dialing), the operation by voice command 
will be canceled.
NOTE
The voice control function may have 
difficulty in some environments and with 
the way some people speak. 
 The followings will help you make the best 
use of the voice control function.
• Speak loud and clear. This makes voice 
recognition easier.
•  When making a call, avoid saying things 
such as “uh”, “um, uh”, “aah”, etc. These 
may be mistaken for other words.
•  Close the windows. Noise from the 
outside can cause recognition mistakes.
•  Ask everyone else in the vehicle to 
please be quiet while you voice-dial a 
call. The voices of others in the vehicle 
can cause recognition mistakes.
•  Words are sometimes mistaken for other 
words with a similar pronunciation.
•  If there is too much ambient noise, 
recognition mistakes may occur.  
Example: Driving through a tunnel, 
driving with chains on the tires
•  Strong air flow from the air conditioner 
or heater may make recognition more 
difficult.
•  In the following cases, voice commands 
are not accepted.  
- Speaking too slow (too fast) 
- Speaking too loud (too softly) 
- Not saying anything or pronunciation is 
unclear 
- Spoke before the “beep”
•  The system cannot recognize voice data 
that is not recorded.
