      6. Customize Display


        1. The customization display can be switched by pressing and holding the DISP switch for 0.8 seconds or more while the setting display is shown on the cruise information display.

        2. The customization item can be switched to by pressing the DISP switch for less than 0.8 seconds.

        3. The setting display can be switched to by pressing the DISP switch for 0.8 seconds or more while a customization item is being displayed.

        4. Settings can be changed by pressing the DISP switch for less than 0.8 seconds while the setting display is being shown.

        A01FC0GE01
        No. Condition
        *1 Pressing DISP switch for 0.8 seconds or more.
        *2 Pressing DISP switch for less than 0.8 seconds.

    3. ECO Lamp


      1. The operating diagram of ECO lamp is as follows:

        A01FBU1E01
        No. Condition
        *1 The opening illumination is turned on.
        *2 The ECO lamp illuminates 0% to 100% in accordance with driving conditions.
        *3 The ECO lamp illuminates 10%.
        *4 The ECO lamp illuminates 10% to 100% in accordance with driving conditions.
        *5 The ECO lamp illuminates 10% after the opening illumination is turned on.

    4. SPORT Lamp


      1. The operating diagram of SPORT lamp is as follows:

        A01FBLUE01

    5. Front Seat Belt Warning System


      1. When the engine switch is on (IG), this system detects the condition of the seat belts based on the signals from the front seat inner belt assembly LH or RH and the occupant classification sensor.

      2. 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 12.4 mph (20 km/h) 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 the 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 a Global Tech Stream (GTS). For details, refer to the Repair Manual.

      3. 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.

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

  3. CONSTRUCTION


    1. Headup Display


      1. The headup display shows information on the windshield glass through the combination meter mirror ECU. The headup display gives the appearance of being displayed ahead of the vehicle.

          *3 The vehicle speed is 5 mph (8 km/h) or more, or the headup display has not been operated for 3 seconds.

    2. Windshield Glass for Headup Display


      1. Windshield glass without a combiner treatment is used for the headup display.

      2. This glass has a wedge-shaped inner PVC film. This film, with its varying thickness, is located between the outer and inner layers of glass.

      3. The light that strikes the glass is reflected by the inner surface of the inner glass, and also by the inner side of the outer surface of outer layer of glass. With a conventional windshield, the light reflected from these 2 surfaces diverges due to the thickness of the glass, resulting in a double image.

      4. The PVC film uses its wedge shape to eliminate the reflection angle difference between the outer glass and inner glass. As a result, the reflected light is displaced to reduce double images.

      5. Thus, the reflected light from the headup display unit is recognized by the driver as a single display image.
