[WITHOUT MOBILE ENTERTAINMENT SYSTEM]PRECAUTION PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS00485
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:

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.

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.
Precautions for Trouble DiagnosisNKS00486
AV COMMUNICATION SYSTEM

Do not apply voltage of 7.0 V or higher to the measurement terminals.

Use the tester with its open terminal voltage being 7.0 V or less.

Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before
checking the circuit.
Precautions for Harness RepairNKS00487
AV COMMUNICATION SYSTEM

Solder the repaired parts, and wrap with tape. [Frays of twisted
line must be within 110 mm (4.33 in).]

Do not perform bypass wire connections for the repair parts.
(The spliced wire will become separated and the characteristics
of twisted line will be lost.)

SYSTEM DESCRIPTION
Revision: 2007 April2007 M35/M45
SYSTEM DESCRIPTIONPFP:00000
System FunctionsNKS00489
Here is an example of functions. For details, refer to the owner's manual or navigation system owner's manual.
AUDIO
Speed Sensitive Volume (for BASE System)

Volume level of this system gone up and down automatically in proportion to the vehicle speed. And the
control level can be selected by the customer.

The audio unit inputs the vehicle signal that is sent from unified meter and A/C amp via CAN communica-
tion through AV (NAVI) control unit.
Precision Phased Audio (for BASE System)

It plays back the sound using the woofer (ultra-low bass and clear midrange sound) and reproduces the
sound with presence.

When the conventional BASS/TREBLE adjustment is a maximum, the sounds might be unclear because
the volume of midrange sound also rises together with the bass and treble. The precision phased audio
can emphasize ultra-low bass and ultra-high treble without changing the midrange sound by digital pro-
cessing using DSP.
NOTE:
When the radio is played, the noise may increase more than the presence due to the characteristics of
broadcasting waves. Therefore, the amplification rate while playing the radio is controlled lower than the
rate while playing CD.
AudioPilot® (for BOSE System)
AudioPilot® is the sound improving system that picks up any noises and the sound of music coming into the
vehicle by a microphone under the steering, and that the BOSE 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.

If low frequency area noise from vehicle is loud, it adjusts low frequency element of music to be bigger
than vehicle noise.

If high frequency area noise from vehicle is loud, it adjusts all frequency element of music to be bigger
than vehicle noise.
Centerpoint® (for BOSE Surround 5.1ch System)
CD and 2.0ch DVD stereo sound played at audio unit and DVD player are subjected to signal processing in
BOSE amp. It can play the surround sound with presence.
VEHICLE INFORMATION SYSTEM

The status of audio, climate control system, fuel consumption, and navigation system (if equipped) are
displayed.

AV (NAVI) control unit receives the data signal from ECM, unified meter and A/C amp and low tire pres-
sure warning control unit via CAN communication. It calculates the values of fuel economy, tire pressure,
and trip computer from the received information and displays them.
NAVIGATION SYSTEM
Location Detection Principle
The navigation system periodically calculates the vehicle's current
position according to the following three signals:

Travel distance of the vehicle as determined by the vehicle
speed sensor

Turning angle of the vehicle as determined by the gyroscope
(angular velocity sensor)

Direction of vehicle travel as 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 read from the map DVD-
ROM, which is stored in the DVD-ROM drive (map-matching), and

(GPS information)
The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data read from the map DVD-
ROM, which is stored in the DVD-ROM drive (map-matching), and
indicated on the screen as a vehicle mark. More accurate data is judged and used by comparing vehicle posi-
tion detection results found by the GPS with the result by map-matching.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.

Travel distance
Travel distance calculations are based on the vehicle speed
sensor input signal. Therefore, the calculation may become
incorrect as the tires wear down. To prevent this, an automatic
distance correction function has been adopted.

Travel direction
Change in the travel direction of the vehicle is calculated by a
gyroscope (angular velocity sensor) and a GPS antenna (GPS
information). They have both advantages and disadvantages.
