System Description=NBEL0171NATS (Nissan Anti-Theft System) has the following immobilizer functions:
ISince only IVIS (NATS) ignition keys, whose ID nos. have been registered into the ECM and IMMU of IVIS
(NATS), allow the engine to run, operation of a stolen vehicle without an IVIS (NATS) registered key is
prevented by IVIS (NATS).
That is to say, IVIS (NATS) will immobilise the engine if someone tries to start it without the registered key
of IVIS (NATS).
IAll of the originally supplied ignition key IDs (except for card plate key) have been IVIS (NATS) registered.
If requested by the vehicle owner, a maximum of five key IDs can be registered into the IVIS (NATS) com-
ponents.
IThe security indicator blinks when the ignition switch is in ªOFFº or ªACCº position. Therefore, IVIS (NATS)
warns outsiders that the vehicle is equipped with the anti-theft system.
IWhen IVIS (NATS) detects trouble, the security indicator lamp lights up while ignition key is in the ªONº
position.
IIVIS (NATS) trouble diagnoses, system initialization and additional registration of other IVIS (NATS) igni-
tion key IDs must be carried out using CONSULT-II hardware and CONSULT-II IVIS (NATS) software.
When IVIS (NATS) initialization has been completed, the ID of the inserted ignition key is automatically
IVIS (NATS) registered. Then, if necessary, additional registration of other IVIS (NATS) ignition key IDs
can be carried out.
Regarding the procedures of IVIS (NATS) initialization and IVIS (NATS) ignition key ID registration, refer
to CONSULT-II operation manual, IVIS/NVIS.
IWhen servicing a malfunction of the IVIS (NATS) (indicated by lighting up of Security Indicator
Lamp) or registering another IVIS (NATS) ignition key ID no., it is necessary to re-register original
key identification. Therefore, be sure to receive ALL KEYS from vehicle owner.

Cellular Airwave InterferenceNBEL0180S0308At times someone other than the Communicator Response Center
operator may be heard. This is caused by Cellular Airwave Inter-
ference and is not caused by an INFINITI Communicator system
malfunction.
Possibility of Positioning Capability DegradedNBEL0180S0309Vehicle positioning is accomplished using the GPS (Global Posi-
tioning System). If the signal from the GPS satellite is obstructed
by a tunnel or building, positioning capability may be degraded or
lost. In this case, the last valid position obtained before the obstruc-
tion is transmitted to the Communicator Response Center. The
precision is also influenced by the location of GPS satellites.
Once the battery cable is disconnected, it will take about 5 minutes
to determine the vehicle location. This is because the memory
related to GPS is lost when the battery cable is disconnected.
OPERATIONNBEL0180S04One Touch ªInformationº DialingNBEL0180S0401IIf the vehicle becomes disabled due to problems such as
engine trouble, press the ªInformationº switch to connect to the
Communicator Response Center and receive the desired ser-
vice.
IWhen the indicator lamp on the switch lights up, it means that
the system has started to contact the Communicator
Response Center. (Voice communication with Communicator
Response Center operator is not available while DATA is being
transmitted even if the indicator lamp is lit.)
IWhen the indicator lamp blinks, it means that the system is
preparing for cellular connection or attempting to re-dial.
One Touch ªMaydayº Emergency DialingNBEL0180S0402IWhen an emergency occurs, press the ªMaydayº emergency
switch to connect to the Communicator Response Center. With
this report, the Communicator Response Center recognizes
that an emergency has occurred and provides necessary ser-
vice.
IThe operator will request a password (if the customer chooses
to establish a password). If the wrong password or if no pass-
word is provided, the Communicator Response Center will
assume the customer is in a duress situation and dispatch
police.
IWhen no voice reply is heard from the vehicle or the sound
heard indicates an emergency situation, the Communicator
Response Center will have the police rush to the scene.
IOther operations are the same as service dialing.
Automatic Air Bag Inflation NotificationNBEL0180S0403IWhen an air bag inflates, the air bag diagnosis sensor unit
sends the air bag inflation signal to the IVCS unit, and the
system automatically dials the Communicator Response Cen-
ter to report the occurrence of an accident.
Stolen Vehicle TrackingNBEL0180S0404IWhen a vehicle is stolen, the owner can contact the Commu-
nicator Response Center to attempt to locate the stolen
vehicle. The Communicator Response Center will activate the
stolen vehicle tracking to locate the vehicle. If the Communi-
cator Response Center successfully locates the vehicle, they
will contact the police to provide the location.

gency call or alarm notification), vehicle location, time, etc.
SLEEP/WAKE UP CONTROLNBEL0180S063 minutes after the ignition switch is turned OFF, the system goes
into the SLEEP MODE to save battery power supply. Communica-
tion with Communicator Response Center is not available in the

GPS signal reception conditions are good. However, the position mark does not return to its proper
position.
Ihe system senses the vehicle location with an error of approximately 100 m (328 ft). Due to the limitation
of precision, the position marker may be inaccurate even if the GPS signal reception condition is good.
IThe navigation system uses GPS data to determine vehicle location. GPS data is compared with other
locational sensing data during the map matching process. The system decides which data is more pre-
cise and uses that data.
IWhen the vehicle is stationary, GPS data cannot be used to make system corrections.
Area designations on the map display and the BIRDVIEWTdisplay differ.
To prevent the display from becoming congested, alphanumeric information is abridged.
[No problem]
Correct position of your vehicle is not displayed.

Vehicle is parked inside a building or in the shadow of a large building. This intercepts the GPS signal.
[Move the vehicle to a more open position.]
GPS signal is not received because objects are placed on the rear parcel shelf.
[Remove objects from the rear parcel shelf.]
GPS satellite position is bad.
[Wait until GPS satellite position improves.]
Vehicle position precision is bad.
The map surface precision display (GPS satellite marker) still remains gray.
[Refer to ªThe map surface precision display (GPS satellite marker) still remains grayº item (Symptoms)]
Vehicle speed and elapsed distance is calculated from the vehicle speed pulse. This pulse is dependent upon
tire size. If tire chains are used on the vehicle, accuracy will be affected (pulse rate will be too fast or too slow).
The same is true if the system installed to your vehicle is removed and installed on another vehicle.
[Drive the vehicle at a speed higher than 30 km/h (19 MPH) for approximately 30 minutes. Automatic read-
justment should occur. If it does not (remains too fast or too slow), distance calibration is required. Or, drive
the vehicle for a short distance. Perform ªSPEED CALIBRATIONº (EL-409). After removing the tire chains,
sensing accuracy may recover by itself.]
Bad map data or system defect (same error consistently occurs in the same area)
ROUTE SEARCH/ROUTE GUIDENBEL0235S03IIf the present location or the destination location is displayed in the avoid area, it is not possible to search
routes.
IIf the avoid area is set to wide range area, it may not be possible to find appropriate routes or search for
alternate routes.
IThe automatic re-route calculates a return to the original route. Because of this, it may not be possible to
search appropriate new routes. If you deviate from the original route and wish to select an appropriate new
route, touch ªRoute Calculationº.
IThe automatic re-route function may sometimes require considerable time.
IDisplayed route number and directional information at a highway junction may differ from the information
posted on the actual road signs.
IDisplayed street name information at a highway exit may differ from the information posted on the actual
road signs.
IStreet name information displayed on the enlarged intersection map may differ from the information posted

The security indicator is located on the instrument panel. The indi-
cator blinks when the ignition switch is in OFF or ACC position.
Therefore, IVIS (NATS) warns outsiders that the vehicle is
equipped with the anti-theft system.
IWhen IVIS (NATS) detects trouble, the security indicator lamp
lights up while ignition switch is in ON position.
This lighting up indicates that the anti-theft is not functioning,
so prompt service is required.
IWhen servicing IVIS (NATS) (trouble diagnoses, system initial-
ization and additional registration of other IVIS (NATS) ignition
key IDs), CONSULT-II hardware and CONSULT-II IVIS (NATS)
software is necessary.
Regarding the procedures of IVIS (NATS) initialization and
IVIS (NATS) ignition key ID registration, refer to CONSULT-II
operation manual, IVIS/NVIS.
Therefore, CONSULT-II IVIS (NATS) software (program card
and operation manual) must be kept strictly confidential to
maintain the integrity of the anti-theft function.
IWhen servicing IVIS (NATS) (trouble diagnoses, system initial-
ization and additional registration of other IVIS (NATS) ignition
key IDs), it may be necessary to re-register original key iden-
tification. Therefore, be sure to receive all keys from vehicle
owner.
A maximum of five key IDs can be registered into IVIS (NATS).
IWhen failing to start the engine first time using the key of IVIS
(NATS) (for example, when interference is caused by another
IVIS (NATS) key, an automated full road device or automated
payment device on the key ring), restart as follows.
a) Leave the ignition switch in ON position for approximately 5
seconds.
b) Turn ignition switch to OFF or LOCK position and wait approxi-
mately 5 seconds.
c) Repeat step 1 and 2.
d) Restart the engine while holding the device (which may have
caused the interference) separate from the registered NATS
key. If the no start condition re-occurs, NISSAN recommends
placing the registered IVIS (NATS) key on a separate key ring
to avoid interference from other devices.
PRECAUTIONS FOR INFINITI COMMUNICATOR (IVCS)NBGI0001S09The purpose of INFINITI Communicator is to increase security for
the vehicle owner by providing a convenient way to contact the
most appropriate emergency assistance provider during an emer-
gency.
Improper operation of the system may result in a police response.
The theft warning system also activates INFINITI Communicator.
For details, refer to INFINITI Communicator (IVCS) in the EL sec-
tion.
