PRECAUTIONS
PRECAUTIONS PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
AKS00BEC
A
The Supplemental Rest raint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used al ong
with a front seat belt, helps to redu ce th e risk or se verit y of i njury to the driv er and front passenge r for ce rtain
types of col lision. Information necessary to service the system safely is includ ed in the SRS a nd SB section of
this Service Manual.
WARNING:
● To avoid rendering the SRS inopera tive, whi ch could incr ease the risk of pe rsonal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
● Improper maintenance, inc luding incorrect removal and installation of the SRS, can lead to per-
sonal injury ca use d by unintentional activ atio n of the system. For re mo va l of Spiral Cable and Air
Bag Module, see the SRS sec tion.
● Do not use electrical test equ ipment o n any circu it related to the SRS unless in structed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

NAVIGATION SYSTEM
NAVIGATION SYSTEM PFP:25915 System Description AKS00F7M
NAVIGATION SYSTEM
For details of navigation system operation procedure, refer to navigation system owner's manual.
Location Detection Principle
The navigation system periodically calculates the vehicle's current
position accor ding to the following three s ignals:
● Travel distance of the vehicle as determined by the vehicle
speed sensor
● Turning angle of the vehicle as determined by the gyroscope
(angular vel ocity 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 DVDROM, 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 position detection results found by the GPS with the result by map-matching.
The current ve hicle position will b e calculated by de tecting the distance the vehicle moved from the previous calculation point and its
direction.
● Travel distanc e
Travel distance calculations are based on the vehicle speed
sensor input signal. Therefore, the calculation may become
incorrect as the tires w ear down. To preven t this, an automatic
distance correction function has been adopted.
● Travel direction
Change in the trav el direction of the vehicle is ca lculated by a
gyroscope (angular velocity sensor) and a GPS antenna (GPS
information). They have both advantages and disadvantages.
SKIB1058E
SEL684V
Type Advantage Disadvantage
Gyroscope
(angular velocity sensor)
GPS antenna
(GPS information)
Can detect the vehicle's turning angle qui te
accurately.
Can detect the vehicle's travel direction
(North/South/East/West).
Direction errors may accumulate when vehicle is
driven for long distances without stopping.
Correct direction cannot be detected when vehicle speed is low.
More accurate traveling direction is detected because priorities are set for the signals from these two
devices according to the situation.

NAVIGATION SYSTEM
Map-Matching
Map-matching compares a current lo cation detecte d by the method
in the “Locati on D etecti on P rinci ple“ (re fer t o AV-16
data from Map DVD-ROM stored in DVD-ROM drive.
NOTE:
The road map data is based on data stored in the map DVD-ROM.
) with a road map
A
B
C
SEL685V
The vehicle position may not be corrected under the following circumstances and after driving for a certain
time when GPS infor mation is difficult to rece ive. In this case , the vehicle mark on th e display must be corrected manually.
● In map-matching, alternative routes to reach the destination will
be shown and prio ritized, after the road on which the vehicl e is
currently driven has been judged and the vehicle mark has been
repositioned.
If there is an error in distance and/or direction, alternative routes
will be shown in differen t orde r of priorit y, and the incorrect road
can be avoided.
If two roads are ru nn ing in paral lel , th ey are of th e s am e p rio rity.
Therefore, the vehi cle ma rk may appear on either of th em alternately, depending on maneuvering of the steering wheel and
configuration of the road.
● Map-matching does not function correctly when a road on which
SEL686V
the vehicle is driving is new and not recorded in the map DVDROM, or when road pattern stored in the map data and the
actual road pattern are different due to repair.
When driving on a road not present in the map, the map-matching function may find anothe r road and position the vehic le mark
on it. Then, when the correct road is detected, the vehicle mark
may change to it.
● Effective range for comparing the vehicle position and travel
direction calcul ated by the distance and direc tion with the road
data read from the map DVD-ROM is limited. Therefore, when
SKIA0613E
there is an excessive gap between current vehicle position and
the position on the map, correction by map-matching is not possible.

NAVIGATION SYSTEM
GPS (Global Positioning System)
GPS (Global Positioning System) was developed for and is controlled by the US Department of Defense. The system utilizes GPS
satellites (NAVSTAR), sending out radio waves while flying on an
orbit around the earth at an altitude of approximately 21,000 km.
The GPS receiver c alculates the vehicle's positi on in three dimensions (latitude/longitude/altitude) according to the time lag of the
radio waves received from four or more GPS satellites (three-dimensional positioning). If radio waves were received only from three
GPS satellites , the GPS r eceiver ca lculates the vehicle's position i n
two dimensions (latitude/longitude), u tilizing the altitude data ca lculated previously with radio waves from four or more GPS satellites
(two-dimensional positioning).
Position correction by GPS is not available while the vehicle is stopped.
Accuracy of GPS will deteriorate under the following conditions:
● In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position
changes.
● The accura cy can be eve n lo w er de pe nd ing on th e ar ra ng em en t of th e GP S sat el l ites ut il i zed for the pos i-
tioning.
● Position detection is not possible when vehicle is in an area where radio waves from the GPS satellite do
not reach, such as in a tunnel, parking lot in a building, and under an elevated highway. Radio waves from
the GPS satellites may not be received when some object is located over the GPS antenna.
NOTE:
● Even a high-precision three dimensional positioning, t he detection re sult has an error about 10 m (30 ft).
● Because the signals of GPS satellite is controlled by the Tracking and Control Center in the United States,
the accuracy may be degraded lower intentionally or the radio waves may stop.

● It calculates the vehicle location according to the signals from
the gyroscope, the vehicle speed sensor, the GPS satellite and
the data of map DVD-ROM, and then transmits the map image
