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:
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.
PRECAUTION A
PRECAUTIONS
EXCEPT FOR MEXICO
B
EXCEPT FOR MEXICO : Precaution for Supplemental Restraint System (SRS) "AIR
BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000009359200
C
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 D
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. E
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 F
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
G
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 Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness H
connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
I
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 J
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 K
battery, and wait at least 3 minutes before performing any service.
EXCEPT FOR MEXICO : Precaution for Battery Service INFOID:0000000009359201

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
M
window function will not work with the battery disconnected.

Sound Equalizer Automatic Switching Function M
Sound quality in a fully-open retractable soft top condition is improved by the correction for bringing the fre-
quency characteristics in a fully-open retractable soft top condition closer to the characteristics in a fully-closed
retractable soft top condition. When the retractable soft top is in a fully-open condition, sound pressure is AV
reduced due to the absence of sound echo generated by sound reflection from the retractable soft top. BOSE
amp. detects an open-close condition of the retractable soft top by receiving a roof status signal from the
retractable soft top control unit and switches the equalizer to correct the frequency characteristics in a fully-
open retractable soft top condition. During the switching of the equalizer, audio stops temporarily due to the O
temporary mute.

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.

PRECAUTIONS
EXCEPT FOR MEXICO
EXCEPT FOR MEXICO : Precaution for Supplemental Restraint System (SRS) "AIR
BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000009359271
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:
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 AIR BAG”.
• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice 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:
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.
EXCEPT FOR MEXICO : Precaution for Battery Service INFOID:0000000009359272
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

COMMUNICATION SIGNAL
• AV control unit function by transmitting/receiving data one by one with each unit (slave unit) that configures
them completely as a master unit by connecting between units that configure MULTI AV system with two AV
communication lines (H, L).
• Two AV communication lines (H, L) adopt a twisted pair line that is resistant to noise.
• AV control unit is connected by CAN communication, and it receives data signal from ECM, combination
meter. It computes and displays fuel economy information value with the obtained information. Transmitting/
receiving of data signal is performed by BCM. Also, it transmits the required signal of vehicle setting and
receives the response signal.
• AV control unit is connected with front display unit and serial communication, and it transmits the required
signal of display and display control and receives the response signal from front display unit.
NAVIGATION SYSTEM FUNCTION
Description
• The AV control unit controls navigation function while GPS tuner has built-in map data, GYRO (angle speed
sensor), on the HDD (Hard Disk Drive).
• The AV control unit inputs operation signal with communication signal, through display (touch panel) and
multifunction switch and steering switch.
• Guide sound is output to front speaker through BOSE amp. from AV control unit when operating navigation
system.
• A vehicle position is calculated with the GYRO (angle speed sensor), vehicle sensor, signal from GPS satel-
lite and map data stored on HDD (Hard Disk Drive), and transmits the map image signal (RGB digital image
signal) to the front display unit.
Position Detection Principle
The navigation system periodically calculates the current vehicle
position according to the following three types of signals.
• Travel distance of the vehicle as determined by the vehicle speed
sensor
• Vehicle turning angle determined by the gyroscope (angular speed
sensor)
• The travel direction of the vehicle determined by the GPS antenna
(GPS information)
The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data, which is stored in the HDD
(Hard Disk Drive) (map-matching), and indicated on the screen with
JSNIA0177GB
a current location mark. More accurate data is used by comparing
position detection results from GPS to the map-matching.
The current position is calculated by detecting the travel distance
from the previous calculation point, and its direction change.
• Travel distance
The travel distance is generated from the vehicle speed sensor
input signal. The automatic distance correction function is adopted
for preventing a miss-detection of the travel distance because of
tire wear etc.
• Travel direction
The gyroscope (angular velocity sensor) and GPS antenna (GPS
information) generate the change of the travel direction. Both have
advantages and disadvantages as per the following descriptions.
SEL684V
SEL685V
G
There is a possibility that the vehicle position may not be corrected in the following case, and when vehicle is
driven over a certain distance or time in which GPS information is hard to receive. Correct manually the cur-
rent location mark on the screen. H
• In map-matching, several alternative routes are prepared and pri-
oritized in addition to the road judged as currently driving on.
Therefore, due to errors in the distance and/or direction, an incor- I
rect road may be prioritized, and the current location mark may be
repositioned to the incorrect road.
If two roads are running in parallel, they are of the same priority.
Therefore, the current location mark may appear on either of them J
alternately, depending on maneuvering of the steering wheel and
configuration of the road, etc.

Operating Signal
Audio system operation can be performed with multifunction switch, preset switch, steering switch, touch
panel function or voice recognition function.
• Operating signal is transmitted to AV control unit with AV communication when it is operated by multifunction
switch or preset switch. The disk ejection operating signal is performed by wiring harness.
• Operating signal is transmitted to AV control unit with steering switch signal when it is operated by steering
switch.
• Refer to the following system description (“VOICE RECOGNITION FUNCTION” and “TOUCH PANEL SYS-
TEM”)for explanation of voice recognition function and touch panel function.
Screen Display
Switching of display is performed with serial communication between display unit and AV control unit.
AM/FM Radio Mode
• AM/FM radio tuner is built into AV control unit.
• Audio signal is received by glass antenna, next it is amplified by antenna amp., and finally it is input to AV
control unit. Audio signal is input to BOSE amp., and BOSE amp. outputs to woofer and each speaker.

control units during operation (not independently). In CAN communication, control units are connected with 2
communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each
control unit transmits/receives data but selectively reads required data only. D

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. G
• 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 oper-
ation of each piece of electrical equipment, and then determine the cause. H
NOTE:
