NORMAL OPERATING CONDITION

NOTE:

Except for the ordinance-designated cities. (Malfunctioning areas may be changed in the updated map disc.)

Examples of Current-Location Mark Displacement

Vehicle's travel amount is calculated by reading its travel distance and turning angle. Therefore, if the vehicle
is driven in the following manner, an error will occur in the vehicle's current location display. If correct location
has not been restored after driving the vehicle for a while, perform location correction.

Detouring route is recommended.

In some areas, highways (gray routes) are not
used for the search. (Note). Therefore, detour
route may be recommended.

Set the route closer to the basic route (gray
route).

A detour route may be shown when some traffic
regulation (one-way traffic, etc.) is set at the area
around the starting point or the destination.

Slightly move the starting point or the destina-
tion, or set the passing point on the route of
your choice.

In the area where highways (gray routes) are
used for the search, left turn has priority around
the current location and the destination (passing
points). For this reason, the recommended route
may be detouring.

System is not malfunctioning.

Landmarks on the map do not
match the actual ones.

This can be happen due to omission or error in
the map data.

As a rule, an updated map DVD-ROM will be
released once a year. Wait until the latest
map has become available.

Recommended route is far from
the starting point, passing points,
and destination.

Starting point, passing points, and destination of
the route guide were set far from the desired
points because route searching data around
these area were not stored.

Reset the destination onto the road nearby. If
this road is one of the highways (gray routes),
an ordinary road nearby may be displayed as
the recommended route.

Road config-
uration

Y–intersections

At a Y intersection or similar gradual divi-
sion of roads, an error in the direction of
travel deduced by the sensor may result in
the current-location mark appearing on the
wrong road.

If after travelling about 10 km (6
miles) the correct location has
not been restored, perform lo-
cation correction and, if neces-
sary, direction correction.

Spiral roads

When driving on a large, continuous spiral
road (such as loop bridge), turning angle
error is accumulated and the vehicle mark
may deviate from the correct location.

Straight roads

When driving on a long, straight road and
slow curve without stopping, map-matching
does not work effectively enough and dis-
tance errors may accumulate. As a result,
the vehicle mark may deviate from the cor-
rect location when the vehicle is turned at a
corner.

Zigzag roads

When driving on a zigzag road, the map
may be matched to other roads in the simi-
lar direction nearby at every turn, and the
vehicle mark may deviate from the correct
location.

Roads laid out in a grid pattern

When driving where roads are laid out in a
grid pattern, or where many roads are run-
ning in the similar direction nearby, the map
may be matched to them by mistake and
the vehicle mark may deviate from the cor-
rect location.

Parallel roads

When two roads are running in parallel
(such as highway and sideway), the map
may be matched to the other road by mis-
take and the vehicle mark may deviate from
the correct location.

NORMAL OPERATING CONDITION

Place

In a parking lot

When driving in a parking lot, or other loca-
tion where there are no roads on the map,
matching may place the vehicle mark on a
nearby road. When the vehicle returns to
the road, the vehicle mark may have devi-
ated from the correct location.
When driving in circle or turning the steer-
ing wheel repeatedly, direction errors accu-
mulate, and the vehicle mark may deviate
from the correct location.

If after travelling about 10 km (6
miles) the correct location has
not been restored, perform lo-
cation correction and, if neces-
sary, direction correction.

Turntable

When the ignition switch is OFF, the navi-
gation system cannot get the signal from
the gyroscope (angular speed sensor).
Therefore, the displayed direction may be
wrong and the correct road may not be eas-
ily returned to after rotating the vehicle on a
turntable with the ignition OFF.

Slippery roads

On snow, wet roads, gravel, or other roads
where tires may slip easily, accumulated
mileage errors may cause the vehicle mark
to deviate from the correct road.

Slopes

When parking in sloped garages, when
travelling on banked roads, or in other cas-
es where the vehicle turns when tilted, an
error in the turning angle will occur, and the
vehicle mark may deviate from the road.

Map data

Road not displayed on the map screen

When driving on new roads or other roads
not displayed on the map screen, map
matching does not function correctly and
matches the location to a nearby road.
When the vehicle returns to a road which is
on the map, the vehicle mark may deviate
from the correct road.

Different road pattern
(Changed due to repair)

If the road pattern stored in the map data
and the actual road pattern are different,
map matching does not function correctly
and matches the location to a nearby road.
The vehicle mark may deviate from the cor-
rect road.

Vehicle

Use of tire chains

When tire chains are used, the mileage is
not correctly detected, and the vehicle mark
may deviate from the correct road.

Drive the vehicle for a while. If
the distance still deviates, ad-
just it by using the distance ad-
justment function. (If the tire
chain is removed, recover the
original value.)

Location Correction by Map-Matching is Slow

• The map-matching function needs to refer to the data of the surrounding area. It is necessary to drive some

distance for the function to work.

• Because map-matching operates on this principle, when there are many roads running in similar directions

in the surrounding area, no matching determination may be made. The location may not be corrected until
some special feature is found.

Name of Road is Not Displayed

The current road name may not be displayed if there are no road names displayed on the map screen.

Contents of Display Differ for Birdview™ and the (Flat) Map Screen

Difference of the BIRDVIEW™ screen from the flat map screen are as follows.
• The current place name displays names which are primarily in the direction of vehicle travel.
• The amount of time before the vehicle travel or turn angle is updated on the screen is longer than for the

(flat) map display.

• The conditions for display of place names, roads, and other data are different for nearby areas and for more

distant areas.

• Some thinning of the character data is done to prevent the display becoming too complex. In some cases

and in some locations, the display contents may differ.

• The same place name, street name, etc. may be displayed multiple times.

Vehicle Mark Shows a Position Which is Completely Wrong

In the following cases, the vehicle mark may appear on completely different position in the map depending on
the GPS satellite signal receiving conditions. In this case, perform location correction and direction correction.
• When location correction has not been done
- If the receiving conditions of the GPS satellite signal is poor, if the vehicle mark becomes out of place, it may

move to a completely different location and not come back if location correction is not done. The position will
be corrected if the GPS signal can be received.

• When the vehicle has traveled by ferry, or when the vehicle has been being towed

Precautions
for driving

Just after the engine is started

If the vehicle is driven just after the engine
is started when the gyroscope (angular
speed sensor) correction is not completed,
the vehicle can lose its direction and may
have deviated from the correct location.

Wait for a short while before
driving after starting the engine.

Continuous driving without stopping

When driving long distances without stop-
ping, direction errors may accumulate, and
the current-location mark may deviate from
the correct road.

Stop and adjust the orientation.

Abusive driving

Spinning the wheels or engaging in other
kinds of abusive driving may result in the
system being unable perform correct detec-
tion, and may cause the vehicle mark to de-
viate from the correct road.

If after travelling about 10 km (6
miles) the correct location has
not been restored, perform lo-
cation correction and, if neces-
sary, direction correction.

How to cor-
rect location

Position correction accuracy

If the accuracy of location settings is poor,
accuracy may be reduced when the correct
road cannot be found, particularly in places
where there are many roads.

Enter in the road displayed on
the screen with an accuracy of
approx. 1mm.
Caution: Whenever possible,
use detailed map for the correc-
tion.

Direction when location is corrected

If the accuracy of location settings during
correction is poor, accuracy may be re-
duced afterwards.

Perform direction correction.

[BOSE AUDIO WITH NAVIGATION]

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 jump 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 different when map matching is done, the vehicle mark may

seem to jump. At this time, the location may be “corrected” 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 stopping 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 location has never been wrong, conditions may cause the
vehicle mark to deviate.

PRECAUTIONS

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

INFOID:0000000001731056

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”.

• 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 har-
ness connectors.

Precaution for Trouble Diagnosis

INFOID:0000000001281897

AV COMMUNICATION SYSTEM

• Do not apply voltage of 7.0 V or higher to the measurement terminals.
• Use the tester with its open terminal voltage being 7.0 V or less.
• Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before

checking the circuit.

Precaution for Harness Repair

INFOID:0000000001281898

AV COMMUNICATION SYSTEM

• Solder the repaired parts, and wrap with tape. [Frays of twisted line

must be within 110 mm (4.33 in).]

• Do not perform bypass wire connections for the repair parts. (The

spliced wire will become separated and the characteristics of
twisted line will be lost.)
