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 BELTS of this Service Information.

WARNINGAlways 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 AIR BAG ". Never use electrical test equipment on any circuit related to the SRS unless instructed to in this 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

WARNINGAlways 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.

Check Compatibility

  1. Make sure the customer's Bluetooth® related concern is understood.
  2. Verify the customer's concern. NOTE: The customer's phone may be required, depending upon their concern.
  3. Write down the customer's phone brand, model, and service provider. NOTE: It is necessary to know the service provider. On occasion, a given phone may be on the approved list with one provider, but may not be on the approved list with other providers.
  4. Go to "www.nissanusa.com/bluetooth/". Using the website's search engine, find out if the customer's phone is on the approved list. If the customer's phone is NOT on the approved list: Stop diagnosis here. The customer needs to obtain a Bluetooth® phone that is on the approved list before any further action. If the feature related to the customer's concern shows as "N" (not compatible): Stop diagnosis here. If the customer still wants the feature to function, they will need to get an approved phone showing the feature as "Y" (compatible) in the "Basic Features" list. If the feature related to the customer's concern shows as "Y" (compatible): Perform diagnosis as per the following table.

  1. The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interference, etc.). Check the symptoms below to diagnose the malfunction.
  2. The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning. Check that noise is caused and/or changed by engine speed, ignition switch turned to each position, and operation of each piece of electrical equipment. Then determine the cause.

Note. CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be incorrectly mastered by the customer on a computer. Check that 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.

SymptomsCause and Counter measure
Cannot playCheck if the disc or USB device was inserted correctly.
Check that the disc 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.
Files with extensions other than ".MP3 (.mp3)", ".WMA (.wma)", ".AAC (.aac)" or ".M4A (.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 compressed audio 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 disc or USB device is protected by copyright.
Poor sound qualityCheck if the disc 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 disc or USB device, some time may be required before the music starts playing.
Music cuts off or skipsThe writing software and hardware combination might not match, or the writing speed, writing depth, writing width, etc., might not match the specifications. Try using the slowest writing speed.
Skipping with high bit rate filesSkipping may occur with large quantities of data, such as for high bit rate data.
Move immediately to the next song when playing.If an unsupported compressed audio file has been given a supported extension like ".MP3", 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 writing software, so the files might not play in the desired order.
Random/Shuffle may be active on the audio system or on a USB device.
Poor reception only from a certain radio broadcast station.Check incoming radio wave signal strength of applicable broadcast station.
Buzz/rattle sound from speakerThe majority of rattle sounds are not indicative of an issue with the speaker, usually something nearby the speaker is causing the rattle.

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.

SymptomsCause and Counter measure
System fails to interpret the command correctly.1. Ensure that the command format is valid.
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 improve the recognition response for the speaker. Refer to " ON BOARD DIAGNOSIS FUNCTION ".
The system consistently selects the wrong entry from the phone book1. 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.
