  2. FUNCTION


    1. Emergency Call Service


      1. The emergency call service automatically makes a call to a G-BOOK center operator in the event of an accident, such as one that makes airbags deploy, in order to support prompt attendance by emergency personnel.

      2. In the event of trouble such as an accident or sudden illness, the DCM (telematics transceiver) can be used to call the emergency call center and send location information and the registered user information.

        A0009TUE04

      3. The emergency call service can be activated either manually or automatically to contact the G-BOOK center.

        Call Method Operation Condition
        Automatic Call An automatic call is made in the event of an accident, such as one that makes the airbags deploy. The call occurs regardless of the condition of the occupants.
        Manual Call In the event of sudden illness or an accident that does not cause the airbags to deploy, a manual call can be made by pressing the emergency call switch in the overhead console. (To press the emergency call switch, the emergency call switch cover needs to be removed.)

      4. The emergency call service operation and contract conditions can be confirmed by accessing the G-BOOK center and performing the following maintenance checks.

        Maintenance Check Outline
        Automatic Maintenance Check The telematics transceiver (data communication module) automatically and periodically accesses the emergency call center to confirm if the user is still registered.
        Manual Maintenance Check The user can press the emergency call switch for 10 seconds or more while the green and red indicator lights are on immediately after the engine switch is turned on (IG) to access the G-BOOK center and confirm that they are still registered.

        Tech Tips

        In the following cases, the emergency call service may not be available or the service quality may suffer.


        • The G-BOOK online service has not been established or the first manual maintenance check has not been completed.

        • Communication is interrupted due to a malfunction of the DCM (telematics transceiver) or any other related device.

        • The location cannot be determined.

        • Communication is interrupted due to a service provider system malfunction.

        • Communication problems occur in the communication network used for the emergency call system.

        • The emergency call provider suspends or halts the emergency call service.

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

    2. G-Security Service


      • G-Security service offers the following services:

        • At that time, with the user away from the vehicle*2, a Short Message Service (SMS) is delivered if any or all of the conditions below (Chart of Vehicle Information to be Notified) are met.

          Tech Tips

          *1: Information after vehicle operations are complete may not be sent due to the vehicle status (DCM (telematics transceiver) is out of electrical wave range, etc.).

          *2: When the key is determined not to be inside the vehicle, and all doors and the engine hood are closed.

          CAUTION:


          • Information may not be delivered, or may arrive late, when the vehicle or the user's cellular telephone is in an area with poor signal strength.

          • Operation reminder notifications may not be delivered if the electrical key transmitter sub-assembly is placed near the windshield glass or door window glass, or on the sliding roof glass, even if the electrical key transmitter sub-assembly is outside the vehicle.

      2. The operator service uses the multi-media module receiver assembly to make calls via the following devices.


        • Cellular phone connection type navigation system: Cellular phone

          It is necessary to register the phone using the Bluetooth hands-free function.

        • Telematics transceiver connection type navigation system: DCM (telematics transceiver)

          It is not necessary to register a phone using the Bluetooth hands-free function.

        Function Outline
        Destination Setting Displays the specified destination location on the navigation system screen.
        Weather Forecast* Displays and reads out weather forecast information for the vehicle's location, destination or a specified area.
        News* Displays and reads out news updates, society, sports and entertainment news.

        Tech Tips

        *: Using the browser content display function built into the navigation system, the following contents can be displayed. If news content is displayed, headlines are read out to assist the user in checking the content easily even while driving.

    5. Navigation System Link Function


      1. The navigation system link function provides the navigation system with real-time information obtained from the G-BOOK center, offering more effective use of the navigation system for the user.

      2. The navigation system link function has the following functions:

        Function Outline
        G Route Search Searches for the most suitable route to the destination based on information about wide-area traffic congestion prediction.

        Searching for POIs on the WEB Transfers POI information, which was searched for on the Mapbar site, to the navigation system. A found POI can be set as a destination or registered as a G-memory point.
        G-memory Point

        • When a POI is searched for using the contents of G-BOOK.com or a website, it can be registered as G-memory point of the memory points in the navigation system.

        • By registering POIs as a G-memory points, a list of G-memory points can be displayed without connecting to the G-BOOK center.

    6. Other Function


      1. The telematics system provides another function in consideration of improving usability.

      2. The other function is as follows:

        Function Outline
