TELEMATICS SYSTEM PRECAUTION


  1. PRECAUTION FOR DISCONNECTING CABLE FROM NEGATIVE AUXILIARY BATTERY TERMINAL

    Note


    • After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

  2. STRICT PROHIBITION OF MANUAL EMERGENCY CALL USING EMERGENCY CALL SERVICE


    1. Do not make emergency calls in non-emergency situations. When performing an inspection, use the manual maintenance check.

      Note


      • If the emergency call service is used to connect to the PSAP in a non-emergency situation, an unnecessary workload will be generated at the PSAP. This may cause a delayed response by the PSAP to other emergency calls.

      • If emergency vehicles are dispatched due to an accidental operation of the emergency call switch, you may be charged or punished according to local law.

    2. If the emergency call switch is accidentally operated:


      1. Contact the PSAP to tell them that the call was made by mistake.

      2. An emergency call cannot be halted or finished from the vehicle. Only the PSAP can halt or finish an emergency call.

      3. If the PSAP cannot be informed that the emergency call was made by mistake, the center will report an emergency to authorities, emergency facilities and dealerships in compliance with its agreements. As a result, emergency vehicles may be dispatched.

  3. INSPECTION PROCEDURE FOR TELEMATICS TRANSCEIVER


    1. The telematics transceiver uses GSM and UMTS type radio wave signals. The radio wave signals and communication lines may occasionally be unstable due to factors such as time of day or location. Therefore, network access errors may occur intermittently due to radio wave signal conditions. To determine if there is a problem, it may be necessary to make a judgment based on the frequency of the phenomenon or by comparing the condition with a comparable type of cell phone.

    2. Disassembly of the telematics transceiver cannot be performed (the case cannot be opened). If the telematics transceiver malfunctions, replace it.

  4. PRECAUTIONS FOR EMERGENCY CALL SERVICE


    1. Depending on the troubleshooting procedure, it may be necessary to enter test mode and perform a test call.

    2. The telematics transceiver functions as the emergency call service device and has the IMEI and ICCID.

  5. PRECAUTION FOR MOBILEPHONE BATTERY


    1. The mobilephone battery (back-up battery) has a service life of not less than 3 years. When the mobilephone battery needs to be replaced, the manual (SOS) switch indicator (red) will illuminate. The telematics transceiver will also store a Diagnostic Trouble Code (DTC).

  6. IF AN EMERGENCY CALL CANNOT BE MADE


    1. The emergency call service may not be available, or the call quality may deteriorate in the following situations. (For details, refer to the terms of service and operation manual for the device.)

      Cause Details
      Communication is interrupted due to the network used for the emergency call system.*

      • The registered vehicle is located outside the cellular phone service area of the emergency call system.

      • The vehicle is overseas.

      • The vehicle is in a cellular phone service area where communication is not possible, such as an indoor environment, a basement parking area, mountains, tunnels or beside a building.

      • Network availability or the time of use is limited, such as when cellular phone networks or public fixed networks (including junction networks) are extremely busy.

      • Network availability is limited by the communication service provider due to a large-scale disaster.

      • The cellular phone network or public fixed network (including junction networks) service used for the emergency call system is suspended or halted due to accidents, maintenance or construction.
      The PSAP system cannot determine the vehicle location.

      • The vehicle is in an area where the Global Navigation Satellite System (GNSS) radio signals cannot be received or where it is difficult for radio waves to penetrate, such as an indoor environment, a basement parking area, mountains, tunnels or beside a building.

      • The vehicle location cannot be determined normally or accurately because the vehicle is in the following areas:


        • Areas that cause a large error in the GNSS location calculation, such as in tunnels or a densely built-up area, or after getting off a ferry.


        • Areas that cause a large error in map matching due to an old map database.

      • The GNSS is malfunctioning.
      Others Although a manual call is made, the situation cannot be confirmed because the user cannot respond to questions from the GNSS.

      Note

      *: Even when the vehicle is within the cellular phone service area, it may be difficult to make emergency phone calls due to radio wave signal conditions or busy lines. In this case, it may not be possible to access the PSAP. As a result, no calls can be made to ask for rescue in the event of a traffic accident. If emergency calls cannot be made, use a landline telephone or cellular phone.
