2001 INFINITI QX4 ESP

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.

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.

IAll indicators illuminate for up to 30 seconds or more
when ignition switch is turned from OFF to ON and the
system performs a self check.
IIf both of MAYDAY and INFORMATION indicators do not
turn off 30 seconds or more after the ignition switch is
turned to ON, the system is malfunctioning.
AUTOMATIC RE-DIAL/AUTO RESET TO READYNBEL0180S08IWhen INFINITI Communicator tries to contact the Communi-
cator Response Center, but the cellular network is busy, the
system attempts to dial for up to 2 hours. This time varies

greatly depending on the cellular network and cellular signal
strength. The system resets to ready when the system com-
pletes the dialing attempts. The vehicle owner can press the
button again if he or she still needs to contact the Communi-
cator Response Center.
IINFINITI Communicator automatically redials if communication
between the vehicle owner and Communicator Response Cen-
ter is lost for some reason.
IThe only way for a transmission to be officially terminated is for
the Communicator Response Center to send an end transmis-
sion signal, which turns off the indicator in the switch. (Com-
munication with Communicator Response Center can not be
terminated by the occupant.)
IIf the vehicle owner start the engine during a call, the conver-
sation may be interrupted. When this happens the system may
try to resume transmission once after the engine has been
started.

GPS (GLOBAL POSITIONING SYSTEM)NBEL0180S09GPS is the global positioning system developed and operated by
the US Department of Defense. GPS satellites (NAVSTAR) trans-
mit radio waves and orbit around the earth at an altitude of approxi-
mately 21,000 km (13,000 miles).
GPS receiver calculates the three-dimensional position of the
vehicle (latitude, longitude, and altitude from the sea level) by the
time difference of the radio wave arriving from more than four GPS
satellites (three-dimensional positioning).
When the radio wave is received from only three GPS satellites, the
two-dimensional position (latitude and longitude) is calculated,
using the altitude from the sea level data calculated by using four
GPS satellites (two-dimensional positioning).
Positioning capability is degraded in the following cases.
IIn two-dimensional positioning, when the vehicle's altitude
from the sea level changes, the precision becomes lower.
IThe location detection performance can have an error of about
100 m (300 ft) even in three-dimensional positioning with high
precision. Because the precision is influenced by the location
of GPS satellites used for positioning, the location detection
performance may drop depending on the location of GPS sat-
ellites.
IWhen the radio wave from GPS satellites cannot be received,
for example, when the vehicle is in a tunnel, in a parking lot
inside building, under an elevated superhighway or near strong
power lines, the location may not be detected. Turbulent/
electric weather conditions may also affect positioning perfor-
mance. If something is placed on the antenna, the radio wave
from GPS satellites may not be received.
