Related to Telephone
The system should respond correctly to all voice comm ands without difficulty. If problems are encountered, try
the following solutions.
Where the solutions are listed by number, try each soluti on in turn, starting with number 1, until the problem is
resolved.
Symptom Possible cause Possible solution
The system does not
recognize your com-
mand.
or
The system recognizes
your command incor-
rectly The interior of the vehicle is too noisy. Close the windows or have other occupants quiet.
The volume of your voice is too low. Speak louder.
The volume if your voice is too loud. Speak softer.
Your pronunciation is unclear. Speak clearly.
You are speaking before the voice recognition is ready
Press and release “ ” switch on the steering
switch, and speak a command after the tone
sounds.
8 seconds or more have passed after you pressed and
released “ ” switch on the steering switch. Make sure to speak a command within 8 seconds
after you press and release “ ” switch on the
steering switch.
Only a limited range of voice commands is usable for
each screen. Use a correct voice command appropriate for the
current screen.
The fan of the air conditioner is too loud. Lower the fan speed as necessary as voice com-
mand can be recognized more easily.
Symptom/ error message Solution
Displays “CO MMAND NOT REC-
OGNIZED” or the system fails to in-
terpret the comm and correctly. 1. Ensure that the command format is valid.
2. Speak clearly without pausing between words and at a level appropriate to the ambient noise
level.
3. Ensure that the ambient noise level is not excessive, for example, windows open or defrost on.
NOTE:
If it is too noisy to use the phone, it is li
kely that voice commands will not be recognized.
4. If optional words of the command have been omitted, then command should be tried with these
in place.
The system consistently selects
the wrong voicetag 1. Ensure that the voicetag requested matches what was originally stored. This can be confirmed
by giving the “Addressbook” Directory or Phone Directory command.
2. Replace one of the voicetags being confused with a different voicetag.
Symptom Solution
System fails to interpret the com-
mand correctly. 1. Ensure that the command is valid.
2. Ensure that the command is spoken after the tone.
3. Speak clearly without pausing between words and at level appropriate to the ambient noise lev-
el 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 improve the recognition response for the speaker. See “Speaker adaptation (SA)
mode” earlier in this section. Refer to “OWNER’S MANUAL”.

RELATED TO ROUTE CALCULATION AND VISUAL GUIDANCE
The vehicle icon is not displayed in
the correct position.The vehicle was transported after the ignition
switch was pressed off, for example, by a ferry
or car transporter.
Drive the vehicle for a while on a road where
GPS signals can be received.
The position and direction of the vehicle icon
may be incorrect depending on the driving en-
vironments and the levels of positioning accu-
racy of the navigation system. This is not a malfunction. Drive the vehicle for
a while to automatically correct the position
and direction of the vehicle icon.
When the vehicle is traveling on a
new road, the vehicle icon is located
on another road nearby. Because the new road is not stored in the map
data, the system automatically places the vehi-
cle icon on the nearest road available.
Updated road information will be included in
the next version of the map data.
The screen does not switch to the
night screen even after turning on
the headlights. The daytime screen was set the last time the
headlights were turned on.
Set the screen to the night screen mode using
when you turn on the headlights.
The map does not scroll even when
the vehicle is moving. The current location map screen is not dis-
played.
Press “MAP”.
The vehicle icon is not displayed. The current location map screen is not dis-
played.
Press “MAP”.
The location of the vehicle icon is
misaligned from the actual position. When using tire chains or replacing the tires,
speed calculations based on the speed sensor
may be incorrect. Drive the vehicle for a while [at approximately
30 km/h (19 MPH) for about 30 minutes] to
automatically correct the vehicle icon posi-
tion.
If this does not correct the vehicle icon posi-
tion, contact an INFINITI dealer.
The map data has a mistake or is incomplete
(the vehicle icon position is always misaligned
in the same area). Updated road information will be included in
the next version of the map data.

viously suggested. Route calculations took priority conditions into consider-
ation, but the same route was calculated.
This is not a malfunction.
A waypoint cannot be added. Five waypoints are already set on the route, including ones
that you have already passed. A maximum of 5 waypoints can be set
on the route. If you want to go to 6 or
more waypoints, perform route calcu-
lations multiple times as necessary.
The suggested route is not dis-
played. Roads near the destination cannot be calculated.
Reset the destination to a main or or-
dinary road, and recalculate the route.
The starting point and destination are too close. Set a more distant destination.
The starting point and destination are too far away. Divide your trip by selecting one or two
intermediate destinations, and per-
form route calculations multiple times.
There are time restricted roads (by the day of the week, by

An indirect route is suggested. If there are restrictions (such as one-way streets) on roads
close to the starting point or destination, the system may
suggest an indirect route.
Adjust the location of the starting of

SYSTEM
Low power consumption mode (BCM sleep)- Low power consumption control is active
- CAN transmission is stopped
LOW POWER CONSUMPTION CONTROL WITH BCM
BCM reduces the power consumption with the following operation in the low power consumption mode.
 The reading interval of the each switches changes from 10 ms interval to 60 ms interval.
Sleep mode activation
 BCM receives the sleep-ready signal (ready) from IPDM E/R, combination meter and automatic back door
control module via CAN communication.
 BCM transmits the sleep wake up signal (sleep) to each unit when all of the CAN sleep conditions are ful- filled.
 Each unit stops the transmission of CAN communication with the sleep wake up signal. BCM is in CAN com- munication sleep mode.
 BCM is in the low power consumption mode and perform the low power consumption control when all of the
BCM sleep conditions are fulfilled with CAN sleep condition.
Sleep condition
Wake-up operation
 BCM transmits sleep wake up signal (wake up) to eac h unit when any condition listed below is established,
and then goes into normal mode from low power consumption mode.
 Each unit starts transmissions with CAN communication by receiving sleep wake up signals. Each unit trans- mit wake up signals to BCM with CAN communication to convey the start of CAN communication.
