Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000005775466
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 harness 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.

HANDS-FREE PHONE SYSTEM ON BOARD DIAGNOSIS
During on board diagnosis the diagnosis function of TEL adapter unit starts with the operation of the steering
switch and performs the diagnosis when ignition switch ACC.
ON BOARD DIAGNOSIS ITEM
The on board diagnosis has 3 modes: the self-diagnosis mode that performs the trouble diagnosis, the
speaker adaptation data deleting mode and the hands-free phone system initialization mode.
CAUTION:
•Perform the diagnosis with the vehicle stopped.
•Perform STEP2 if necessary.
STEP MODE Description
The self-diagnosis mode performs the microphone test and
STEP 1 Self-diagnosis
Hands-free phone system initialization
STEP 2
Speaker adapta tion data del et ing
the diagnosis of TEL adapter unit, TEL antenna and steering
switch, and then reads out the results with the sound and indicates them on the audio screen.
Hands-free phone system initialization mode can perform
the initialization of hands-free phone system.
The speaker adaptation data deleting mode can delete the
speaker adaptation data.
SELF-DIAGNOSIS RESULTS
Self-diagnosis mode reads out the self-diagnosis results and indicates DTC on the audio screen.
NOTE:
•Error count is read out simultaneously when reading out the DTC name.
•The errors are read out continuously when some errors occur at the same time. The DTC displays are combined and displayed. For example, DTC 01100 is displayed when DTC 01000 and DTC 00100 are indicated
at the same time.

NORMAL OPERATING CONDITION
Description INFOID:0000000005490547
RELATED TO AUDIO
•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.
•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.
Symptoms Cause and Counter measure
Check that the disc was inserted correctly.
Check that the disc is scratched or dirty.
Check if there is condensation inside the player. If there is, wait until the condensation is gone
(about 1 hour) before using the player.
If there is a temperature increase error, the CD player will play correctly after it returns to the normal temperature.
Cannot play
Poor sound quality
It takes a relatively long time before
the music starts playing.
Music cuts off or skips
Skipping with high bit rate files Skipping may occur with large quantities of data, such as for high bit rate data.
Move immediately to the next song
when playing.
The songs do not play back 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.
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 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 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 is protected by copyright.
Check if the disc is scratched or dirty.
Bit rate may be too low.
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.
The 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.
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, there will be approximately 5 seconds of no sound
and then the player will skip to the next song.
The playback order is the order in which the files were written by the writing software. Therefore,
the files might not play in the desired order.

Symptoms Cause and Counter measure
System fails to interpret the command correctly.
The system consistently selects
the wrong entry from the phone
book.
NORMAL OPERATING CONDITION
[AUDIO SYSTEM]
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 AV-18 , "
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.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000005745223
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 harness 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.
