NOTE:
Vehicle operation information, refer to Owner's Manual.

BASIC OPERATIONS

RELATED TO VOICE RECOGNITION

Related to telephone

The system should respond correctly to all voice commands without difficulty. If problems are encountered, try
the following solutions.
Where the solutions are listed by number, try each solution in turn, starting with number 1, until the problem is
resolves.

RELATED TO AUDIO

• The majority of the audio malfunctions are the result of outside causes (bad CD/cassette, electromagnetic

interference, etc.). Check the symptoms below to diagnose the malfunction.

• The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.

Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and oper-
ation of each piece of electrical equipment, and then determine the cause.

NOTE:
• CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be incor-

rectly mastered by the customer on a computer.

• Check if the CDs carry the Compact Disc Logo. If not, the disc is not mastered to the “red book” Compact

Disc Standard and may not play.

Symptom

Possible cause

Possible solution

No image is displayed.

The brightness is at the lowest setting.

Adjust the brightness of the display.

The system is in the video mode.

Push <DISC> to change the mode. 

The display is turned off.

Push <Day/Night> to turn on the display.

The screen is too dim. The move-
ment is slow.

The temperature in the interior of the vehicle is low. 

Wait until the interior of the vehicle has 
warmed up.

Some pixels in the display are dark-
er or brighter than others.

This condition is an inherent characteristic of liquid 
crystal displays.

This is not a malfunction.

Some menu items cannot be se-
lected.

Some menu items become unavailable while the ve-
hicle is driven.

Park the vehicle in a safe location, and 
then operate the multi AV system.

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 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”.

The system consistently selects 
the wrong voicetag

1. Ensure that the phone book entry name requested matches what was originally stored. This 
can be confirmed by using the “List Names” command. 

2. Replace one of the names being confused with a new name.

Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise from trains and other
sources, is not a malfunction.

NOTE:

• Fading noise: This noise occurs because of variations in the field strength in a narrow range due to mountains or buildings blocking

the signal.

• Multi-path noise: This noise results from a time difference between the broadcast waves directly from the station arriving at the

antenna and the waves reflected by mountains or buildings.

Symptom

Cause and Counter measure

Cannot play

Check if the CD was inserted correctly.

Check if the CD is scratched or dirty.

Check if there is condensation inside the player, and if there is, wait until the condensation is gone 
(about 1 hour) before using the player.

If there is a temperature increase error, the player will play correctly after it returns to the normal 
temperature. 

If there is a mixture of music CD files (CD-DA data) and MP3/WMA files on a CD, only the music 
CD files (CD-DA data) will be played. 

Files with extensions other than “.MP3”, “.WMA”, “.mp3”, or “.wma” cannot be played. In addition, 
the character codes and number of characters for folder names and file names should be in com-
pliance with the specifications.

Check if the disc or the file is generated in an irregular format, This may occur depending on the 
variation or the setting of MP3/WMA writing applications or other text editing applications.

Check if the finalization process, such as session close and disc close, is done for the disc.

Check if the CD is protected by copyright.

Poor sound quality

Check if the CD is scratched or dirty.

It takes a relatively long time before 
the music starts playing.

If there are many folder or file levels on the MP3/WMA CD, or if it is a multisession disc, some 
time may be required before the music starts playing.

Music cuts off or skips

The writing software and hardware combination might not match, or the writing speed, writing 
depth, writing width might not match the specifications. Try using the slowest writing speed. 

Skipping with high bit rate files

Skipping may occur with large quantities if data such as for high bit rate data.

Move immediately to the next song 
when playing

When a non-MP3/WMA file has been given an extension of “.MP3”, “.WMA”, “.mp3”, or “.wma”, 
or when play is prohibited by copyright protection, the player will skip to the next song.

The songs do not play back in the 
desired order.

The playback order is the order in which the files were written by the software, so the files might 
not play in the desired order.

PRECAUTIONS

PRECAUTION

PRECAUTIONS

FOR USA AND CANADA

FOR USA AND CANADA : Precaution for Supplemental Restraint System (SRS) "AIR 
BAG" and "SEAT BELT PRE-TENSIONER"

INFOID:0000000005528609

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIR BAG”.

• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s)
with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly
causing serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

FOR USA AND CANADA : Precaution for Trouble Diagnosis

INFOID:0000000005528610

AV COMMUNICATION SYSTEM

• Do not apply voltage of 7.0 V or higher to the measurement terminals.
• Use the tester with its open terminal voltage at 7.0 V or less.
• Turn ignition switch OFF and disconnect the battery cable from the negative terminal before checking the cir-

cuit.

FOR USA AND CANADA : Precaution for Harness Repair

INFOID:0000000005528611

AV COMMUNICATION SYSTEM

• Solder the repaired parts, and wrap with tape. [Frays of twisted line

must be within 110 mm (4.33 in).]
