  2. MULTI-INFORMATION DISPLAY

    Item Detail
    Cruise information display Average fuel consumption after refueling Five types of information (average fuel consumption after refueling, average fuel consumption, average vehicle speed, current fuel consumption, and driving range) can be displayed.
    Average fuel consumption
    Average vehicle speed
    Current fuel consumption
    Driving range
    ECO driving indicator zone display

    • In addition to the cruise information display, the combination meter assembly indicates the ECO driving indicator zone display.


      1. The ECO driving indicator zone display will be displayed when all of the following conditions are met:


        1. Engine switch is on (IG).

        2. Shift lever is in D.

        3. Snow mode is not selected.

      2. The multi-information display is used to display the ECO driving indicator zone display. When the vehicle is driven with the ECO driving indicator zone display bar in the recommended range, the ECO drive indicator light comes on to inform the driver that the vehicle is being driven in a manner that helps to achieve low fuel consumption.

      3. The ECO driving indicator zone display shows the current accelerator opening angle as a bar moving inside a box. The box on the left represents the recommended accelerator angle range for economical driving. The ECM transmits and calculates the recommended accelerator opening angle range based on an accelerator opening angle.

      4. When the accelerator opening angle exceeds the recommended range, the meter CPU turns off the ECO drive indicator light and blinks the right side of the ECO driving indicator zone display to inform the driver that the vehicle is not being driven economically.

      5. In addition, when the following condition is met, the meter CPU turns off the ECO drive indicator light and the ECO driving indicator zone display:


        1. The shift lever is in any position except D.
    Multi-information display Each system warning Interrupts the multi-information display immediately when a warning occurs.
    Customization display Displays the customized setting of each item.
    Illumination control Displays the current illumination level and adjust the combination meter assembly brightness.

    Tech Tips

    The timing of the ECO driving indicator light turning on and off may differ from the indication of the ECO driving indicator zone display, as their update cycles are different.
