  1. OPERATING CONDITION


    1. Eco Driving Indicator Light Operation Condition


      1. The Eco driving indicator light can begin to operate when all of the following conditions are met:

        Condition

        • The READY indicator light is illuminated (the hybrid system is operating).

        • While the vehicle is running.

        • The vehicle is at a speed of 130 km/h (81 mph) or below.

        • The shift position is in D.

        • Power mode is not selected.

        • The EV mode indicator light is turned off.

        • The hybrid system is normal.

        • The hybrid system temperature is normal.

    2. Hybrid System Indicator Operation Condition


      1. The hybrid system indicator will begin to operate when both of the following conditions are met:

        Condition

        • The READY indicator light is illuminated (the hybrid system is operating).

        • The shift position is in D or B.

  2. SYSTEM CONTROL


    1. Front Seat Belt Warning


      1. 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.

      2. The front seat belt warning blinks each front seat belt warning light individually when the driver does not fasten the driver seat belt or the front passenger does not fasten the front passenger seat belt.

      3. The front seat belt warning buzzer sounds when the vehicle speed reaches approximately 20 km/h (12.4 mph) or more while the front seat belt warning light is blinking. If the seat belt is not then fastened after approximately 30 seconds have elapsed since the buzzer sounded, the front seat belt warning buzzer sounds more loudly than normal for approximately 90 seconds.

    6. Eco Driving Indicator Light


      1. When the power management control ECU determines, by using information such as vehicle speed, vehicle power, shift position and drive mode, that the driving is Eco, it turns on Eco driving indicator light. The operating diagram of Eco driving indicator light function is as follows:

        A01LPLGE01

    7. Light Control Rheostat


      1. The brightness of the instrument panel can be adjusted when the taillights are turned on.

      2. The nighttime brightness level of the combination meter can be adjusted between 2.08% and 16.5% of the daytime brightness level of 100%, by using a dial-type switch. The indicator lights on the combination meter can be turned off by further decreasing the brightness level.

  4. CONSTRUCTION


    1. Combination Meter


      1. A reflective display method is used to display the speed meter, fuel gauge, instantaneous fuel consumption and shift position. Using the Vacuum Fluorescent Display (VFD), the light emitted by the vacuum fluorescent display panel is reflected in the reflective glass, allowing a virtual image to be visible to the driver's eyes.

      2. Light emitted in the display area is transmitted through the reflective glass, allowing the warning lights, indicator lights and information on the multi-information display to be visible to the driver's eyes.

    2. Touch Tracer Display


      1. A touch sensor is provided on frequently used switches such as the DISP switch, TRIP switch, audio and air conditioning switches. The touch tracer display is displayed when any of the switches is touched by the driver's finger, and the switch is activated when pressed.

    3. Headup Display


      1. The Headup display projects the image from the dot Vacuum Fluorescent Display (VFD), built into the Headup display unit (combination meter mirror ECU), in a position approximately 2 m (6.6 ft) forward of the driver using a concave mirror and the windshield, in order to support the driver with various information.

      2. By changing the angle of the concave mirror, the position of the image displayed can be adjusted.

    4. 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 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 film's wedge shape is used to eliminate the reflection angle difference between the outer glass and inner glass. This recombines the reflected light and eliminates the double image.

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