Precaution
NBEL0177
CAUTION:
I
Use CONSULT-II to set the system “Demonstration mode” if INFINITI Communicator needs to be
activated during service procedures. (For details of the demonstration mode, refer to EL-379.)
I
Make sure to turn the demonstration mode OFF before returning the vehicle to the owner.
I
In 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.
I
If 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.
I
When “Mayday” 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.
I
IVCS 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 “System Setting”, EL-381.
I
Before servicing the vehicle, confirm that the VIN memorized by the IVCS unit is the same as the
VIN on the vehicle’s identification plate.
