AV-646
< SYMPTOM DIAGNOSIS >[BOSE AUDIO WITH NAVIGATION]
NORMAL OPERATING CONDITION
Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise from trains and other
sources, is not a malfunction.
NOTE:
Fading noise: This noise occurs because of variations in the field strength in a narrow range due to mountains or buildings blocking
the signal.
Multi-path noise: This noise results from a time difference between the broadcast waves directly from the station arriving at the
antenna and the waves reflected by mountains or buildings.
RELATED TO NAVIGATION
As a result of a slight operating error, a normal symptom might be taken as a malfunction. Therefore, at first,
please check for yourself as per the following table.
Move immediately to the next song
when playing.When a non-MP3/WMA file has been given an extension of “.MP3”, “.WMA”, “.mp3”, or “.wma”,
or when play is prohibited by copyright protection, the player will skip to the next song.
The songs do not play back in the
desired order.The playback order is the order in which the files were written by the software, so the files might
not play in the desired order. Symptom Cause and Counter measure

The map does not scroll even when
the vehicle is moving.The display is not set to the current location map. Set the display to the current location map.
The vehicle icon is not displayed. The display is not set to the current location map. Set the display to the current location map.
The GPS icon is not displayed. GPS signal cannot be received.Move the vehicle to an open area without
obstacle. If an object is placed on the up-
per area of GPS antenna, remove it.
No voice guidance is available.The route guidance was cancelled.If the route destination guidance has been
cancelled, reactivate the route guidance.
The volume is set very low. Adjust the volume of your voice guidance.
Some pixels in the display are dark-
er or brighter than others.This is an inherent characteristic of liquid crystal dis-
plays. Although the liquid crystal display is manufac-
tured with a technology of very high accuracy and it
has more than 99.99% effective pixels, a chip or a
permanent lighting of pixels might occur at 0.01% or
less.Please continue using the NAVI system,
as it is not a malfunction.
A mottle remains for a while after
turning the ignition switch ON.When it is cold, due to the characteristics of the liq-
uid crystal display backlight, a brightness mottle
might occur.It will disappear a few minutes later when
the backlight is warmed-up.
The screen is not clear.The adjustment of the contrast or the brightness is
inadequate.Adjust the contrast and the brightness of
the display.
The vehicle icon is not displayed in
the correct location. (The location
of the vehicle icon is misaligned
from the actual position.) The vehicle icon might be misaligned from the actual
position due to the satellite condition, the vehicle
condition (driving location or driving condition), etc.
Also, when the vehicle is traveling on a road whose
information is not stored in the map data, a new road
for example, the vehicle icon might be misaligned
from the actual position.Drive the vehicle for a while. The current
location is automatically corrected using
the map-matching and GPS information.
(It may take a few minutes.) If the GPS in-
formation is not used and the current loca-
tion is not corrected automatically, park the
vehicle in a safe location, and then correct
the current vehicle location.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003809633
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 AIRBAG” and “SEAT BELT” of this
Service Manual.
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 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 the “SRS AIRBAG”.
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.

OPERATION
Depress the brake pedal several times at 5-second intervals with the
engine stopped. Start the engine with the brake pedal fully
depressed. Check that the clearance between brake pedal and dash
lower panel decreases.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. This is a normal phenomenon due to
the brake system operation.
AIR TIGHT
Idle the engine for 1 minute to apply vacuum to the brake booster,
and stop the engine. Then depress the brake pedal several times
at 5-second intervals until the accumulated vacuum is released to
atmospheric pressure. Check that the clearance between brake
pedal and dash lower panel gradually increases (A → B → C) each
time the brake pedal is depressed during this operation.
Depress the brake pedal with the engine running. Then stop the
engine while holding down the brake pedal. Check that the brake
pedal stroke does not change after holding down the brake pedal
for 30 seconds or more.
