Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001724596
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. Information necessary to service the system safely is included in the SR and SB section 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 SR section.
 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.

NORMAL OPERATING CONDITION

DescriptionINFOID:0000000001728625
RELATED TO AUDIO
 The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interfer-
ence, 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 incor-
rectly 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.
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.
RELATED TO TELEPHONE
Symptoms Cause and Counter measure
Cannot playCheck that the CD was inserted correctly.
Check that the CD is scratched or dirty.
Check that there is condensation inside the player, and if there is, wait until the condensation is
gone (about 1 hour) before using the player.
The player will play correctly after it returns to the normal temperature if there is a temperature
increase error.
Only the music CD files (CD-DA data) will be played if there is a mixture of music CD files (CD-
DA data) and MP3/WMA files on a CD.
Files with extensions other than “.MP3”, “.WMA”, “.mp3”, or “.wma” cannot be played.
Check that the finalization process, such as session close and disc close, is done for the disc.
Check that the CD is protected by copyright.
Poor sound quality Check that 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.
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.
Symptom Possible cause Possible solution
The system does not recognize the
command.
The system recognizes the com-
mand incorrectly.The interior of the vehicle is too noisy.Close the windows or have other occupants
be quiet.
The volume of the voice is too low. Speak louder.
Pronunciation is unclear. Speak clearly.
Voice recognition mode is not yet ready to speak.Push the release “ ” on the steering
switch, and speak a command after the
tone sounds.
5 seconds or more have passed after pushed and
released “ ” on the steering switch.Make sure to speak a command within
5seconds after push and release “ ” on
the steering switch.

INFOID:0000000001731028
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. Information necessary to service the system safely is included in the “SRS AIRBAG” 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 AIRBAG”.
 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.
