PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BKS00201
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 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 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 per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS 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.

AUDIO (WITH INTEGRATED DISPLAY SYSTEM)PFP:28185
System DescriptionBKS0020H
AUDIO SYSTEM

The audio system with the A/C and AV switch (operation panel switch) and the audio unit are designed
separately has been adopted.

Operation signal from A/C and AV switch is transmitted to audio unit through display unit with the commu-
nication line, and it controls the audio system.

Display signal from audio unit is transmitted to display unit through the communication line, and then the
operating state of the audio system is displayed in the screen.

A/C and AV switch can perform the operation check of each switch by starting the self-diagnosis. For
details, refer to AV- 1 3 , "
A/C and AV Switch Self-Diagnosis Function" .

For Audio System operation information, refer to Owner's Manual.

AUDIO (WITH INTEGRATED DISPLAY SYSTEM)

Symptom ChartBKS0020Q

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 malfunction-
ing. 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 then determine the cause.

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 if 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.

Make sure that other operation except audio system can be performed with A/C and AV switch. If these
operations are inoperative with A/C and AV switch, refer to AV- 5 8 , "
Unable to Operate System with A/C
and AV Switch" .
NOTE:
Noise resulting 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 a time difference between the broadcast waves directly from the
station arriving at the antenna and the waves reflected by mountains or buildings.
Symptom Possible malfunction location
Audio system does not work properly.

INTEGRATED COLOR DISPLAY SYSTEMPFP:28090
System DescriptionBKS0027J
For system operation information, refer to Owner's Manual.
INTEGRATED COLOR DISPLAY SYSTEM

Each control unit that comprises the system is connected with a communication circuit. It transmits/
receives data signals including request signals and response signals, and controls the system.

The display control unit transmits/receives data signals to/from each control unit with CAN communica-
tion. It performs an arithmetical operation on fuel information values by using data obtained from the con-
trol units, and then displays the calculated values on the screen.

The display control unit receives vehicle speed signals that are transmitted from the unified meter and A/
C amp., performs an arithmetical operation on drive information values, and then displays the calculated
values on the screen.

The images displayed on the monitor screen contain display control unit-generated RGB images, and rear
view images transmitted from the rear view camera control unit.

The display control unit controls image switching and image quality adjustments by communications with
the display.
REAR VIEW MONITOR

A rear view monitor was set to vehicle, which can check rearward on screen when backing up the vehicle.

For easier recognition of the vehicle width and the distance to the objects, the guide lines of distances and
rear are combined with the rear view image.

Image quality of the rear view image and of the RGB image can be adjusted separately.
