    3. Eco Driving Indicator


      1. The operating diagram of Eco Driving Indicator is as follows:

        A01N5KAE10
      2. When the ECM, using information (such as vehicle speed, accelerator pedal depressed volume, shift lever position, engine speed signal (engine RPM data), shift range, drive mode, and so on), calculates that the vehicle is driven in Eco-friendly, it turns on Eco Driving Indicator Light and shows the bar graph of Eco Driving Indicator Zone Display within Zone of Eco driving.

      3. When the ECM calculates that the acceleration exceeds Zone of Eco driving, it turns off Eco Driving Indicator Light and blinks the right side of Eco Driving Indicator Zone Display.

      4. The operation of Eco Driving Indicator is as follows:

        Vehicle Condition Eco Driving Indicator Zone Display Eco Driving Indicator Light
        Stopped A01N5J6 Turns off
        Eco Driving A01N5K7 Turns on
        Non-Eco Driving A01N5L1 Turns off
      5. Eco Driving Indicator can be deactivated in the following ways: Eco Driving Indicator Light can be deactivated from Eco Driving Indicator Light customization display of the multi-information display.

    4. Front Seat Belt Warning Function


      1. When the engine switch is on (IG), this system detects the condition of the seat belts based on the signals from the driver and front passenger seat belt buckle switches and the occupant detection sensor.

      2. On the models except models for G.C.C. countries, the multi buzzer sounds when the vehicle speed exceeds 20 km/h (12.4 mph) to emphasize the fact that the seat belt is unbuckled. After 30 seconds, the sound changes for emphasis. The sound continues for 90 seconds. Once a multi buzzer begins to sound, it will continue until the seat belt is buckled or the engine switch is turned off.

      3. On the models for G.C.C. countries, when the seat belt is unbuckled, the multi buzzer sounds 5 times 1.8 seconds after the engine switch is turned on (IG). The multi buzzer sounds when the vehicle speed exceeds 20 km/h (12.4 mph) to emphasize the fact that the seat belt is unbuckled. After 9.6 seconds, the sound changes for emphasis. The sound continues for 20 seconds. Once a multi buzzer begins to sound, it will continue until the seat belt is buckled or the engine switch is turned off.

        Tech Tips

        Upon receiving a request from a user who cannot wear a seat belt for a special reason, the multi buzzer warning can be canceled using the intelligent tester II. For details, refer to the corresponding Repair Manual for this model.

      4. Occupant Detection Sensor


        • The occupant detection sensor, which is enclosed in the seat cushion of the front passenger seat, is used to detect whether or not the front passenger seat is occupied.

        • This sensor consists of a construction in which 2 electrode sheets sandwich a spacer. When the occupant is seated, the electrode sheets come in contact with each other through the hole provided in the spacer portion, thus enabling the current to flow.

        • Thus, the sensor detects whether or not an occupant is seated in the front passenger seat.

  3. FAIL-SAFE


    1. Eco Driving Indicator


      1. When any of the following conditions are met, Eco Driving Indicator Light is turned off and Eco Driving Indicator Zone Display is stopped:


        • Engine Signal Malfunction

        • CAN Signal Malfunction
