Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"
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 AIRBAG " and " SEAT BELT " .
| WARNING | Always observe the following items for preventing accidental activation: To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that 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 " SRS AIRBAG ". Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Service Information. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. |
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
| WARNING | Always observe the following items for preventing accidental activation: When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never 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. |
Cautions in Removing Battery Terminal and AV Control Unit (Models with AV Control Unit)
| CAUTION | Remove battery terminal and AV control unit after a lapse of 30 seconds or more after turning the ignition switch OFF. |
Note. After the ignition switch is turned OFF, the AV control unit continues operating for approximately 30 seconds. Therefore, data corruption may occur if battery voltage is cut off within 30 seconds.
AV COMMUNICATION SYSTEM
- Do not apply voltage of 7.0 V or higher to the measurement terminals.

Simple Check for Bluetooth™ Communication
If cellular phone and TEL adapter unit cannot be connected with Bluetooth™ communication, following procedure allows the technician to judge which device has malfunction
Scheme 175
- Turn ON cellular phone, not connecting Bluetooth™ communication.
- Start CONSULT, then start Windows®.
- Set CONSULT near a cellular phone.
- When operated Bluetooth™ registration by cellular phone, check if CONSULT* would be displayed on the device name. (If other Bluetooth™ device is located near cellular phone, a name of the device would be displayed also.)
Note. *: Displayed device name is "NISSAN-".
- If no device name is displayed, cellular phone is malfunctioning. Repair the cellular phone first, then perform diagnosis.
- If CONSULT is displayed on device name, cellular phone is normal*. Perform diagnosis as per the following table
*: There is no 100% guarantee that cellular phone operates all functions on AV control unit. Different phone manufacturers implement Bluetooth™ in different ways. Phones on Supported Phone List are tested and any minor exceptions are listed.

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 resolved.
| Symptom | Solution |
|---|---|
| System fails to interpret the command 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 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 improve the recognition response for the speaker. See "Speaker adaptation (SA) mode" . 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. |
| NOTE |
|---|
| If it is too noisy to use the phone, it is likely that the voice commands will not be recognized. |
- 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 operation 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, AAC, M4A) or could be incorrectly 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 | 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/AAC/M4A files on a CD, only the music CD files (CD-DA data) will be played. | |
| Files with extensions other than ".MP3", ".WMA", ".AAC", "M4A", ".mp3", ".wma", ".aac" or ".m4a" cannot be played. In addition, the character codes and number of characters for folder names and file names should be in compliance 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/AAC 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. | |
| Discs recorded in live file system format are not supported. (For Microsoft Windows Vista, check the settings.) | |
| 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/AAC/M4A 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/AAC file has been given an extension of ".MP3", ".WMA", ".AAC", ".M4A", ".mp3", ".wma", ".aac" or ".m4a" 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. |
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.
