AV-118

< SYMPTOM DIAGNOSIS >

[AUDIO WITH NAVIGATION]

NORMAL OPERATING CONDITION

THE CURRENT POSITION MARK JUMPS.

In the following cases, the current location mark may appear to jump as a result of automatic correction of the
current location.
• When map matching has been done
- The current location mark may seem to jump if current location and the current location mark are different

when map matching is done. At this time, the location may be “corrected” to the incorrect road or to a loca-
tion which is not on a road.

• When GPS location correction has been done
- The current location mark may seem to jump if current location and the current location mark are different

when location is corrected using GPS measurements. At this time, the location may be “corrected” to a loca-
tion which is not on a road.

THE CURRENT LOCATION MARK IS IN A RIVER OR THE SEA.

The navigation system moves the current location mark with no distinction between land and rivers or sea. It
may appear that the vehicle is driving in a river or the sea if the location mark is somehow out of place.

CURRENT LOCATION MARK ROTATES WITHOUT OPERATION

The rotating condition is recorded as the stop condition if the ignition switch is turned ON with the turntable
rotating. Therefore, the current location mark might rotate when actually stopping.

WHEN DRIVING ON THE SAME ROAD, SOMETIMES THE CURRENT LOCATION MARK IS IN THE
CORRECT PLACE AND SOMETIMES IT IS IN THE INCORRECT PLACE.

The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and operation of the steering wheel, the location detection results will be dif-
ferent. Therefore, even on a road on which the location has never been incorrect, conditions may cause the
vehicle mark to deviate.

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 of the way map matching operates, when there are many roads running in similar directions in the

surrounding area a matching determination may be impossible. The location will remain uncorrected until
some special feature is found.

ALTHOUGH THE GPS RECEIVING DISPLAY IS GREEN, THE VEHICLE MARK DOES NOT RE-
TURN TO THE CORRECT LOCATION.

• GPS accuracy has a malfunction range of about 10 m (30 ft). In some cases the current location mark may

not be on the correct street, even when GPS location correction is done.

• The navigation system compares the results of GPS location detection with the results from map-matching

location detection. The one that is determined to have higher accuracy is used.

• Position correction by GPS is not available while the vehicle is stopped.

THE NAME OF THE CURRENT PLACE IS NOT DISPLAYED.

The current place name might not be displayed when there is no name of place information in the map screen.

THE DISPLAY IS DIFFERENT BETWEEN BIRDVIEW

®

 AND (FLAT) MAP DISPLAY.

The following is different at Birdview

®

.

• The current place name displays names that 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 trimming of the character data is done to prevent the display from 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.

PRECAUTIONS

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

INFOID:0000000001731029

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. 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.
