Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000004064152

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 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 har­ness connectors.

[BASE AUDIO]

NORMAL OPERATING CONDITION

Description INFOID:0000000004095401

The majority of the audio concerns are the result of outside causes (bad CD, electromagnetic interference,
etc.).

NOISE

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

•Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-

tains or buildings blocking the signal.

•Multi-path noise: This noise results from the waves sent directly from the broadcast station arriving at the

antenna at a different time from the waves which reflect off mountains or buildings.
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 determine the cause.

NOTE:

The source of the noise can be found easily by listening to the noise while removing the fuses of electrical
components, one by one.

Type of Noise and Possible Cause

Occurrence condition Possible cause

Occurs only when engine is ON.

The occurrence of the noise is linked with the operation of the fuel pump. • Fuel pump condenser

Noise only occurs when various
electrical components are oper­ating.

The noise occurs constantly, not just under certain conditions.

A cracking or snapping sound occurs while the vehicle is being driven, especially when
it is vibrating excessively.

A continuous growling noise occurs. The speed of
the noise varies with changes in the engine speed.

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000004095402

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 SR and SB sections 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 har­ness connectors.

NOTE:

Cellular telephones must have their wireless connection set up (paired) before using the Bluetooth telephone
system.
Bluetooth telephone system allows users who have a Bluetooth equipped cellular telephone to make a wire­less connection between their cellular telephone and the Bluetooth control unit. Hands-free cellular telephone
calls can be sent and received. Some Bluetooth cellular telephones may not be recognized by the Bluetooth
control unit. When a cellular telephone or the Bluetooth control unit is replaced, the telephone must be paired
with the Bluetooth control unit. Different cellular telephones may have different pairing procedures. Refer to

BLUETOOTH CONTROL UNIT

When the ignition switch is turned to ACC or ON, the Bluetooth control unit will power up. During power up, the
Bluetooth control unit is initialized and performs various self checks. Initialization may take up to 10 seconds.
During this time, the Bluetooth ON indicator will flash until initialization is complete. If a phone is present in the
vehicle and paired with the Bluetooth control unit, Nissan Voice Recognition will then become active. Bluetooth
telephone functions can be turned off using the Nissan Voice Recognition system.

STEERING WHEEL AUDIO CONTROL SWITCHES

When buttons on the steering wheel audio control switch are pushed, the resistance in steering wheel audio
control switch circuit changes depending on which button is pushed. The Bluetooth control unit uses this sig­nal to perform various functions while navigating through the voice recognition system.
The following functions can be performed using the steering wheel audio control switch:

•Initiate Self Diagnosis of the Bluetooth telephone system

•Start a voice recognition session

•Answer and end telephone calls

•Adjust the volume of calls

MICROPHONE

The microphone is located in the roof console assembly. The microphone sends a signal to the Bluetooth con­trol unit. The microphone can be actively tested during self-diagnosis.

AUDIO UNIT

The audio unit receives signals from the Bluetooth control unit and sends audio signals to the audio amp. then
on to the speakers.

BLUETOOTH ON INDICATOR

The Bluetooth ON indicator is located in the overhead console. The indicator will flash during power up whi­lethe Bluetooth control unit is initializing. This process may take up to 10 seconds. If a phone is present in
thevehicle and paired with the Bluetooth control unit, the indicator will remain on to indicate that the system
isready for voice commands. The indicator flashes during self-diagnosis.

The Bluetooth control unit has two diagnostic checks. The first diagnostic check is performed automatically
every ignition cycle during control unit initialization. The second diagnostic check is performed by the techni­cian using the steering wheel audio control switches prior to trouble diagnosis.

BLUETOOTH CONTROL UNIT INITIALIZATION CHECKS

•Internal control unit failure

•Bluetooth antenna connection open or shorted

•Steering wheel audio control switches [SEND( )/END( )] stuck closed

•Vehicle speed pulse count

• Microphone connection test (with playback to operator)

•Bluetooth inquiry check

OPERATION PROCEDURE

1. Turn ignition switch to ACC or ON.

2. Wait for the Bluetooth system to complete initialization. This may take up to 10 seconds.
