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.

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

Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSION-
ER"

INFOID:0000000004219610

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 SR 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 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 SR 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 har-

ness connectors.

Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000004499302

NOTE:

• Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-

tion, then disconnect both 12-volt battery cables.

• After finishing work, confirm that all control unit connectors are connected properly, then re-connect both 12-

volt battery cables.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.

This vehicle is equipped with a push-button ignition switch and a steering lock unit.

If the 12-volt battery is disconnected or discharged, the steering wheel will lock and cannot be turned.

If turning the steering wheel is required with the 12-volt battery disconnected or discharged, follow the proce-

dure below before starting the repair operation.

OPERATION PROCEDURE

1. Connect both 12-volt battery cables.

NOTE:

Supply power using jumper cables if 12-volt battery is discharged.

2. Carry the Intelligent Key or insert it to the key slot and turn the push-button ignition switch to ACC position.

(At this time, the steering lock will be released.)

3. Disconnect both 12-volt battery cables. The steering lock will remain released with both 12-volt battery

cables disconnected and the steering wheel can be turned.

4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both 12-volt battery cables. With the brake pedal released,

turn the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steer-

ing wheel will lock when the push-button ignition switch is turned to LOCK position.)

6. Perform self-diagnosis check of all control units using CONSULT-III.
