Theft warning system INFINITI QX4 2001 Factory Owner's Guide

PrecautionNBEL0177CAUTION:
IUse CONSULT-II to set the system ªDemonstration modeº if INFINITI Communicator needs to be
activated during service procedures. (For details of the demonstration mode, refer to EL-379.)
IMake sure to turn the demonstration mode OFF before returning the vehicle to the owner.
IIn the demonstration mode, no service from the Communicator Response Center is available.
Therefore, even if the customer encounters an emergency, no service will be dispatched.
IIf the theft warning system is activated for more than 7 seconds, INFINITI Communicator will dial
to the Communicator Response Center automatically. The operator will contact the customer to
confirm whether the vehicle has been stolen or not.
IWhen ªMaydayº emergency dialing is activated (if the system is not in the demonstration mode),
the Communicator Response Center operator will come online. If there is no emergency, the
operator will ask the occupant for the user password (option). Failure to provide the correct pass-
word results in a police response.
IIVCS unit memory includes VIN (Vehicle Identification Number) and other such vehicle specific
data. Therefore, the IVCS unit cannot be transferred to another vehicle. When the IVCS unit is
replaced, the new unit must be set up and programmed. The INFINITI Communicator system auto-
matically contacts the Communicator Response Center the first time the vehicle is started after a
phone number has been changed or a module (IVCS unit) is replaced. The VIN will be written in
the memory of the new unit by transmitting data from the Communicator Response Center. For
details, refer to ªSystem Settingº, EL-381.
IBefore servicing the vehicle, confirm that the VIN memorized by the IVCS unit is the same as the
VIN on the vehicle's identification plate.
Communicator Response Center Telephone
Number for Technicians
NBEL0178The Communicator Response Center telephone number for technicians is1-888-427-4812.
Whenever an INFINITI dealer technician dials the above number, the following information will be required by
the Communicator Response Center operator.
ICustomer name
IUnit ID number of old IVCS unit (For details, refer to EL-367.)
IUnit ID number of new IVCS unit
IVIN
IDealer name and code (For security purposes)

Precaution
EL-348

IThe vehicle location data is calculated using GPS.
IThe vehicle ignition switch must be turned to the ON position
to obtain the vehicle location. (This is because the system is
in the sleep mode when the ignition switch is OFF.)
IOnce this function starts up, regardless of the ignition switch
position, the system keeps transmitting the vehicle location
until the cancel signal is transmitted from the Communicator
Response Center.
IWhile this function is operating, the operator can covertly moni-
tor what is happening inside the vehicle through the hands-free
microphone.
Alarm NotificationNBEL0180S0405IWhen theft warning system sounds an alarm for more than 7
seconds because of improper access, the alarm signal is
transmitted from the smart entrance control unit to the IVCS
unit, and the system executes automatic dialing to the Com-
municator Response Center.
If the alarm is reset before 7 seconds has elapsed, the
INFINITI Communicator will not place a call to the Communi-
cator Response Center.
IThis function operates regardless of ignition switch position.
IWhile this function is operating, the operator can covertly moni-
tor what is happening inside the vehicle through the hands-free
microphone.
Remote Door UnlockNBEL0180S0406IWhen the door is locked with the key inside the vehicle, the
door can be unlocked by contacting the Communicator
Response Center. (Proof that the person calling is the owner
must be received by the Communicator Response Center.)
IWhen the ignition key is in the ªOFFº position, the system is in
the sleep mode. Therefore, back door outside handle must be
pulled to wake up the system.
ITo perform remote door unlock, call the Communicator
Response Center and follow the operator's instructions.
NOTE:
IWhen the system contacts the Communicator Response
Center, data including the vehicle location is transmitted
to the Communicator Response Center.
ICommunication with the Communicator Response Center
is not completed until the completion signal is transmitted
from the Communicator Response Center. (Any calls to
the Communicator Response Center can only be termi-
nated by Communicator Response Center.)
IFunctions other than alarm notification and remote door
unlock operate while the ignition switch is ON and only for
three minutes after the switch is turned OFF.
IOnce a call to the Communicator Response Center is
made, the communication continues regardless of the
ignition key switch position.
IAll the voice communication with the Communicator
Response Center is made through the hands-free tele-
phone.
IWhen the INFINITI Communicator system is activated, the
handset does not function.

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.
