PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS000C3
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 Battery ServiceNKS000C4
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.

Trouble DiagnosisNKS002ED

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.

Refer to "SERVICE BULLETIN NTB04-119" for the diagnosis of satellite radio.
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.

Diagnosis by Error History

When having a difficulty on the investigation of cause due to multiple errors with a reproducible malfunc-
tion, turn ON the ignition switch from OFF mode after making a memo of the item and number of time (or
delete “Error History”). Check “Error History” again after the malfunction was reproduced, and then per-
form diagnosis focusing on the item of which number of time increased.

DVD-ROM error history may be restored because DVD-ROM cannot be temporarily read. (Driving on
rough road etc.) Then, erase the error history. (This is not a malfunction.) Perform service in “Action to
take” if error history are repeatedly indicated again.
Error item Possible cause Action to take
GPS Antenna ErrorGPS antenna connection malfunction
is detected1. Start self-diagnosis, and make sure of
the result.
2. If any error is found, GO TO 3. If any
error is not found, delete the error his-
tory and end the diagnosis. (This is not
a malfunction.)
3. Check if GPS antenna feeder line is
snapped or pinched.
4. If the results from the above checkup
show no malfunction, replace GPS
antenna, and then restart self-diagno-
sis.
5. If self-diagnosis results still show any
malfunction, replace NAVI control unit.
FLASH-ROM Error Of Control Unit
NAVI control unit malfunction is
detected1. Start self-diagnosis, and make sure of
the result.
2. If any error is found, replace NAVI con-
trol unit. Refer to AV- 9 8 , "
Removal and
Installation of NAVI Control Unit" . If any
error is not found, delete the error his-
tory and end the diagnosis. (This is not
a malfunction.) Connection Of Gyro
GPS Communication Error
GPS malfunction is detectedIf the symptoms such as the GPS receipt
malfunction occur, intermittent malfunc-
tion caused by strong radio interference
may be detected.
If the malfunction always occurs, replace
NAVI control unit. GPS ROM Error
GPS RAM Error
GPS RTC Error
DVD-ROM Mechanism not Detected

Malfunction is detected on DVD-
ROM drive pickup lens in NAVI con-
trol unit

There is dirt and damage on the
DVD-ROM1. Check if the inserted DVD-ROM is
specified for this navigation system,
and the DVD-ROM is dirty, scratched or
warped.
2. If the results from the above checkup
show no malfunction, insert the same
DVD-ROM, and then restart self-diag-
nosis.
3. If self-diagnosis results still show any
malfunction, replace NAVI control unit. DVD-ROM Communication Error

For Navigation System operation information, refer to Navigation System Owner's Manual.
BASIC OPERATIONS
NOTE:
Locations stored in the Address Book and other memory functions may be lost if the vehicle's battery is disconnected or is discharged. If
this occurs, service the vehicle's battery as necessary and re-enter the information in the Address Book.
VEHICLE MARKS
Symptom Possible cause Possible solution
No image is displayed.The brightness is at the lowest setting. Adjust the brightness of the display.
The display is turned off.Press and hold the button to turn on the
display.
No voice guidance is available. or
The volume is too high or too low.The volume is not set correctly, or it is turned
off.Adjust the volume of voice guidance.
No map is displayed on the
screen.The DVD-ROM is not inserted, or it is inserted
upside down.Insert the DVD-ROM correctly.
A screen other than map screen is displayed. Press the “MAP” button.
The pickup lens of the DVD unit is dirty.The pickup lens can become dirty depending
on how you use the vehicle. Contact a NIS-
SAN dealer or qualified workshop for pickup
lens cleaning.
The screen is too dim. The move-
ment is slow.The temperature in the interior of the vehicle is
low.Wait until the interior of the vehicle has
warmed up.
Some pixels in the display are
darker or brighter than others.This condition is an inherent characteristic of
liquid crystal displays.This is not a malfunction.
Some menu items cannot be
selected.Some menu items become unavailable while
the vehicle is driven.Park the vehicle in a safe location, then oper-
ate the navigation system.
Symptom Possible cause Possible solution
Names of roads and locations dif-
fer between plan view and BIRD-
VIEW
™ .This is because the quantity of the displayed
information is reduced so that the screen does
not become difficult to read. There is also a
chance that names of the roads or locations
may be displayed several times, and the names
appearing on the screen may be different
because of a processing procedure.This is not a malfunction.
The vehicle mark is not displayed
in the correct position.The vehicle was transported after the ignition
switch was turned off, for example, by a ferry or
car transporter.Drive the vehicle for a while on a road where
GPS signals can be received.
The position and direction of the vehicle mark
may be incorrect depending on the driving envi-
ronments and the levels of positioning accuracy
of the navigation system.This is not a malfunction. Drive the vehicle for
a while to automatically correct the position
and direction of the vehicle mark.
When the vehicle is travelling on a
new road, the vehicle mark is
located on another road nearby.The system automatically places the vehicle
mark on the nearest available road, because
the new road is not stored in the map data.Updated road information will be included in
the next version of the DVD-ROM.
The screen does not switch to the
night screen even after turning on
the headlights.The daytime screen was set the last time the
headlights were turned on.Set the screen to the night screen mode using
button when you turn on the headlights.
The map does not scroll even
when the vehicle is moving.The current location map screen is not dis-
played.Press the “MAP” button.
The vehicle mark is not displayed.The current location map screen is not dis-
played.Press the “MAP” button.
