    • Before performing inspections or repairs which may cause warning messages or DTCs to occur, such as a simulation test or road test, it is necessary to activate warning notification restraint mode so that the G-BOOK center does not recognize the warnings as real ones.

    • Warning notification restraint mode can be entered by using the GTS or operating the multi-display assembly.

    Tech Tips

    The warning notification function sends a warning ON signal, received from the combination meter assembly via CAN communication, to the G-BOOK center using the G-BOOK device if a warning is displayed in the vehicle due to a vehicle malfunction.

    1. Warning notification restraint mode

      Tech Tips

      To cancel warning notification restraint mode, turn the engine switch off and on (IG) to display the service mode screen and cancel warning notification restraint mode.

      1. Warning notification restraint mode (Using the GTS)

        1. Turn the engine switch off.

        2. Connect the GTS to the DLC3.

        3. Start the engine.

        4. Turn the GTS on.

        5. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

      2. Warning notification restraint mode (Using the multi-display assembly)

        1. Enter diagnostic mode of navigation system.

    1. Do not make an emergency call when not in emergency situations. For inspections, use the manual maintenance check.


      • If the emergency call service is used to connect to the G-BOOK center when not in an emergency situation, an unnecessary workload will be generated at the G-BOOK center. This may cause a delayed response by the G-BOOK center 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 related laws.

    2. If the emergency call switch is accidentally operated;

      1. If the emergency call switch is accidentally operated, contact the G-BOOK center to tell them that the call was made by mistake.

      2. An emergency call cannot be halted or finished from the vehicle. Only the G-BOOK center can halt or finish the call.

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


    1. If replacing any of the following parts, refer to Initialization of Repair Instruction.

      • Telematics transceiver (data communication module [DCM])

      • Radio receiver assembly

    2. When replacing the radio receiver assembly, it is not necessary to cancel the G-BOOK contract. (If canceled, a new G-BOOK contract needs to be created after replacement.)

    3. On this model, the radio receiver assembly functions as the G-BOOK device and has the G-BOOK ID.


    1. The telematics transceiver uses a CDMA2000 1X type radio wave signal. The radio wave signals and communication lines may occasionally be unstable depending on time or location factors. Therefore, network access errors may occur intermittently because of 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 making a comparison with a comparable type of cell phone.

    2. The radio receiver assembly and the telematics transceiver have a one-to-one relationship on the registered telematics system. Therefore, if the radio receiver assembly or telematics transceiver is replaced, the network cannot be accessed unless vehicle contract setting is performed. Use of a substitute component is also not possible to confirm network access.

    3. Disassembly of the telematics transceiver is not permitted (the case cannot be opened). If the telematics transceiver malfunctions, replace it.


    1. Depending on the troubleshooting method, a manual maintenance check may be performed.

      Tech Tips

      Communication charges are not incurred for the manual maintenance check because the telematics transceiver is used for communication (the communication cost is included in the G-BOOK cost).

    2. The telematics transceiver functions as the emergency call service device and it has the mayday ID.


    1. The emergency call system regularly performs an automatic maintenance check and communication test with the G-BOOK center so that the emergency call service can always function correctly. There are no operations required to initiate an automatic maintenance check. The automatic maintenance check is performed as follows:

      Tech Tips

      • The automatic maintenance check ends 1 to 2 minutes after it starts.

      • During the automatic maintenance check, a telephone call or network access is not possible using the telematics system. In this case, wait several minutes before trying again.

      • If communication is interrupted for some reason after the automatic maintenance check has started, the automatic maintenance check will resume the next time the engine switch is turned on (ACC).

      • There are no communication charges incurred for the manual and automatic maintenance check because the telematics transceiver is used for communication (the communication cost is included in the G-BOOK cost).


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

      Cause Details
      Communication is interrupted due to malfunctions in the G-BOOK device or any other related device. The G-BOOK device does not operate normally, such as when the device is damaged or malfunctioning due to an impact caused by a collision.
      Communication is interrupted due to a G-BOOK center system error.
      • The G-BOOK center system may need either periodic or urgent maintenance.

      • An extreme volume of emergency calls is made to the G-BOOK center due to a large-scale traffic accident or fire.

      • Malfunctions or problems with the G-BOOK center system.

      • The G-BOOK center system is damaged due to a fire.

      • The emergency call service is suspended or halted due to emergency call provider reasons.

      Communication is interrupted due to the network used for the emergency call system.*
      • The registered vehicle is located outside the cellular phone service area used for 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 G-BOOK center system cannot determine the vehicle location.
      • The vehicle is in an area where the Global Positioning System (GPS) radio waves 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 of the location calculation using the GPS, 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 GPS is malfunctioning.

      • Although a manual call is made, the situation cannot be confirmed because the user cannot respond to questions from the G-BOOK center.

      • The G-BOOK contract has not been established, the user fell behind in payments or canceled the service.

      • The emergency call service start procedure has not been completed.


      *: Even when the vehicle is within the cellular phone service area, it may be difficult to make emergency or phone calls due to radio wave signal conditions or busy lines. In this case, it may not be possible to access the G-BOOK center. 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.


    1. If the theft deterrent system is activated, the G-BOOK center makes a phone call to the customer.


      • When servicing the vehicle, make sure that the vehicle does not experience any conditions that could cause a telephone call to be made by a G-BOOK operator.

      • Before performing inspections or repairs which may activate the alarm notification function, be sure to inform the customer that they may receive a telephone call from a G-BOOK operator.

      Tech Tips

      The alarm notifications can be canceled via the multi-display assembly screen.
