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

INFOID:0000000009163192

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.

Precaution for Battery Service

INFOID:0000000009163193

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.

MULTI AV SYSTEM

AV-11

< SYSTEM DESCRIPTION >

[BASE AUDIO WITH NAVIGATION]

• 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.
• The AV control unit is connected with CAN communication line and receives data signals from the ECM,

combination meter, TCM, AWD control unit, A/C auto amp., ABS actuator and electric unit (control unit),
steering angle sensor and low tire pressure warning control unit. Using the obtained information, it computes
values for the display items relating to the fuel consumption information, multifunction meter, and tire pres-
sure information and displays them.

• AV control unit is connected with display and serial communication, and it transmits the required signal of

display and display control and receives the response signal from display.

• The AV control unit, which has the vehicle setting function, transmits and receives data on vehicle setting

condition via CAN communication with the BCM.

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 audio 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 display.

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
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.

Input signals are prioritized in each situation. However, this order of priority may change in accordance with
more detailed travel conditions so that the travel direction is detected more accurately.

Map-matching

Map-matching repositions the vehicle on the road map when a new
location is judged to be more accurate. This is done by comparing
the current vehicle position (calculated by the normal position detec-
tion method) from the map data stored in the HDD (Hard Disk Drive).

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.
• 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-
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
alternately, depending on maneuvering of the steering wheel and
configuration of the road, etc.

• Map-matching does not function correctly when road on which the

vehicle is driving is new, etc. and not recorded in the map data.
Also, map-matching does not function correctly when road pattern
stored in the map data and the actual road pattern are different due
to repair, etc.
Therefore, the map-matching function judges other road as a cur-
rently driving road if the road is not in the map, and displays the
current location mark on it. Later, the current location mark may be
repositioned to the road if the correct road is detected.

• Effective range for comparing the vehicle position and travel direc-

tion calculated by the distance and direction with the road data is
limited. Therefore, correction by map-matching is not possible
when there is an excessive gap between current vehicle position and the position on the map.

GPS (Global Positioning System)

GPS (Global Positioning System) is developed for and is controlled
by the US Department of Defense. The system utilizes GPS satel-
lites (NAVSTAR), transmitting out radio waves while flying on an orbit
around the earth at an altitude of approximately 21,000 km (13,049
mile).
The receiver calculates the travel position in three dimensions (lati-
tude/longitude/altitude) according to the time lag of the radio waves
that four or more GPS satellites transmit (three-dimensional position-
ing). The GPS receiver calculates the travel position in two dimen-
sions (latitude/longitude) with the previous altitude data if the GPS
receiver receives only three radio waves (two-dimensional position-
ing). GPS position correction is not performed while stopping the
vehicle.

Accuracy of the GPS will deteriorate under the following conditions:
• In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position changes.
