Operating tips
To get the best performance out of the INFINITI
Voice Recognition system, observe the following:● Keep the interior of the vehicle as quiet as
possible. Close the windows to eliminate
surrounding noises (traffic noises, vibration
sounds, etc.) , which may prevent the system
from recognizing voice commands correctly.
● Wait until the tone sounds before speaking a
command. Otherwise, the command will not
be received properly.
● Start speaking a command within 5 seconds
after the tone sounds.
● Speak in a natural voice without pausing
between words.
Giving voice commands
To operate INFINITI Voice Recognition (VR) ,
press and release the
button located on
the steering wheel. After the tone sounds, speak
a command.
The command given is picked up by the micro-
phone, and voice feedback is given when the
command is accepted.
● If you need to hear the available commands
for the current menu again, say “Help” and
the system will repeat them. ●
If a command is not recognized, the system
announces, “Command not recognized.
Please try again.” Make sure the command is
said exactly as prompted by the system and
repeat the command in a clear voice.
● If you want to go back to the previous com-
mand, you can say “Go back” or “Correc-
tion” any time the system is waiting for a
response.
● You can cancel a command when the sys-
tem is waiting for a response by saying,
“Cancel” or “Quit.” The system announces
“Cancel” and ends the VR session. You can
also press and hold the
button on the
steering wheel for 5 seconds at any time to
end the VR session. Whenever the VR ses-
sion is cancelled, a double beep is played to
indicate you have exited the system.
● If you want to adjust the volume of the voice
feedback, press the volume control switches
(+ or -) on the steering wheel while being
provided with feedback. You can also use
the radio volume control knob.
● In most cases you can interrupt the voice
feedback to speak the next command by
pressing the
button on the steering
wheel. ●
To use the system faster, you may speak the
second level commands with the main menu
command on the main menu. For example,
press the
button and after the tone
say, “Call Redial.”
How to say numbers
INFINITI Voice Recognition requires a certain
way to speak numbers in voice commands. Refer
to the following rules and examples. ● Either “zero” or “oh” can be used for “0”.
Example: 1-800-662-6200
– “One eight oh oh six six two six two oh oh”, or
– “One eight zero zero six six two six two oh oh”
● Words can be used for the first four digits
places only.
Example: 1-800-662-6200
– “One eight hundred six six two six two oh oh”,
– NOT “One eight hundred six six two sixty two hundred,” and
– NOT “One eight oh oh six six two sixty two hundred”

TROUBLESHOOTING GUIDE
The system should respond correctly to all voice
commands without difficulty. If problems are en-
countered, try the following solutions.
Where the solutions are listed by number, try
each solution in turn, starting with number 1, until
the problem is resolved.
SymptomSolution
System fails to interpret the command correctly. 1. Ensure that the command is valid. For additional information, refer to “List of voice commands” in this section.
2. Ensure that the command is spoken after the tone.
3. Speak clearly without pausing between words and at a level appropriate to the ambient noise level in the vehicle.
4. Ensure that the ambient noise level is not excessive (for example, windows open or defroster on) . NOTE: If it is too
noisy to use the phone, it is likely that the voice commands will not be recognized.
5. If more than one command was said at a time, try saying the commands separately.
6. If the system consistently fails to recognize commands, the voice training procedure should be carried out to im-
prove the recognition response for the speaker. For additional information, refer to “Voice Adaptation (VA) mode” in
this section.
The system consistently selects the wrong entry from the
phone book. 1. Ensure that the phone book entry name requested matches what was originally stored. This can be confirmed by
using the “List Names” command. For additional information, refer to “Phonebook” in this section.
2. Replace one of the names being confused with a new name.

tion completes, voice commands will not be ac-
cepted. Please wait until the INFINITI Voice Rec-
ognition initialization is completed.
BEFORE STARTING
To get the best recognition performance from
Voice Recognition, observe the following:
● The interior of the vehicle should be as quiet
as possible. Close the windows to eliminate
the surrounding noises (traffic noise and vi-
bration sounds, etc.) , which may prevent the
system from correctly recognizing the voice
commands.
● Wait until the tone sounds before speaking a
command.

WARNING
●Do not leave children or adults who
would normally require the assistance
of others alone in your vehicle. Pets
should also not be left alone. They
could accidentally injure themselves or
others through inadvertent operation of
the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause
severe or possibly fatal injuries to
people or animals.
● Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or col-
lision, unsecured cargo could cause
personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
●Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or
death. ●
If you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle
inspected immediately.
● Do not run the engine in closed spaces
such as a garage.
● Do not park the vehicle with the engine
running for any extended length of time.
● Keep the rear vent windows, liftgates,
doors and trunk lids (if so equipped)
closed while driving, otherwise exhaust
gases could be drawn into the passen-
ger compartment. If you must drive with
one of these open, follow these
precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial to
high to circulate the air.
● If electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the liftgate or the body,
follow the manufacturer’s recommen-
dation to prevent carbon monoxide en-
try into the vehicle. ●
The exhaust system and body should be
inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
●The exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
