PRECAUTIONS
PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EKS006SH
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 and SB section of this Service Man-
ual.
WARNING:
q 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 per-
formed by an authorized NISSAN/INFINITI dealer.
q 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.
q 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.
Wiring Diagrams and Trouble Diagnosis EKS001RC
When reading wiring diagrams, refer to the following:
q Refer to GI-14, "How to Read Wiring Diagrams"
q Refer to PG-2, "POWER SUPPLY ROUTING"
When performing trouble diagnosis, refer to the following:
q Refer to GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES"
q Refer to GI-26, "How to Perform Efficient Diagnosis for an Electrical Incident"

q to every terminals 1 and 2 of instrument panel speakers, front and rear door speakers and woofer.
AV COMMUNICATION LINE
Audio system components (Audio unit, BOSE speaker amplifier, etc.) are connected by AV communication line
and controlled by signals from the multi-function switch.
AUDIOPILOTTM SYSTEM
AUDIOPILOTTM is the sound improving system that picks up any noises or the sound of music coming into the
vehicle by a microphone under the clock, and that the BOSE speaker amp. revises the frequency feature of
music at real time in response to the frequency feature of the noise while driving and listening to music.
q If low frequency area noise from vehicle is loud, it adjusts low frequency element of music to be bigger
than vehicle noise.
q If high frequency area noise from vehicle is loud, it adjusts high frequency element of music to be bigger
than vehicle noise.
q If vehicle noise is smaller than the setting volume, correction is not performed.
This compensate vehicle noise when listening to music.
