< SYMPTOM DIAGNOSIS >[AUDIO SYSTEM]
NORMAL OPERATING CONDITION
- Because calculation of the current location cannot be
done when traveling with the ignition off, for example
when traveling by ferry or when being towed, the location before travel is displayed. If the precise location
can be detected with GPS, the location will be corrected.
Vehicle Mark Jumps
In the following cases, the vehicle mark may appear to ju mp as a result of automatic correction of the current
location.
• When map matching has been done
- If the current location and the vehicle mark are diff erent when map matching is done, the vehicle mark may
seem to jump. At this time, the location may be “corre cted” to the wrong road or to a location which is not on
a road.
• When GPS location correction has been done
- If the current location and the vehicle mark are different when the location is corrected using GPS measure-
ments, the vehicle mark may seem to jump. At this time, the location may be “corrected” to a location which
is not on a road.
Vehicle Mark is in a River or Sea
The navigation system moves the vehicle mark with no distinction between land and rivers or sea. If the vehi-
cle mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.
Vehicle Mark Automatically Rotates
The system wrongly memorizes the rotating status as st opping when the ignition switch is turned ON with the
turntable rotating. That causes the vehicle mark to rotate when the vehicle is stopped.
When Driving on Same Road, Sometimes Vehicle Mark is in Right Place and Sometimes it is in Wrong Place
The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and the operation of the steering wheel, \
the location detection results will be
different. Therefore, even on a road on which the lo cation has never been wrong, conditions may cause the
vehicle mark to deviate.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000004834913
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 severi ty 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 w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SR and SB section of this Service Man-
ual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 Necessary for Steering Wheel Rotation After Battery Disconnect
INFOID:0000000004834914
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecti ng both battery cables with the ignition knob in the
″ LOCK ″ position.
• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS , an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.

5. When the repair work is completed, return the ignition switch to the
″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of a ll control units using CONSULT-III.
