Current Fuel Consumption
The combination meter calculates current fuel consumption based on the following signals, and the calculated value is displayed on the information display.
Current fuel consumption can be compared with average fuel consumption.

note
  • Current fuel consumption on the information display is updated approximately every 0.1 seconds.
  • Current fuel consumption on the information display shows 30 l/100km (0 mpg) when vehicle speed is 0 km/h (0 MPH).
 
 
Average Fuel Consumption
The combination meter calculates average fuel consumption based on the following signals, and the calculated value is displayed on the information display.

  • Average fuel consumption on the information display is updated approximately every 30 seconds.
  • Soon after a reset or when the electric motor switch is ON, “– – –” is displayed until after a travel of 30 seconds and approximately 500 m (0.31 mile).
 
 
Current Vehicle Speed
The combination meter calculates current vehicle speed based on the following signals, and the calculated value is displayed on the information display.

  • Average vehicle speed on the information display is updated approximately every 30 seconds.
  • Soon after a reset, “−−−” is displayed until after 30 seconds.
 
 
Travel Time
The combination meter measures and displays travel time (READY indicator: ON time).
 
 
Travel Distance
The combination meter measures and displays travel distance.
 
 
ECO Pedal Guide
The ECO pedal guide consists of Gauge 1 (displays accelerator pedal angle) and Gauge 2 (displays the guideline of ECO driving).
GAUGE1
  • PHEV-ECU corrects the accelerator pedal angle to the maximum angle for ECO driving, according to vehicle speeds.
    The maximum accelerator pedal angle increases/decreases as the vehicle speed increases/decrease.
    The maximum accelerator angle corrected by PHEV-ECU is the limitation of ECO driving. The ECO driving is possible only when the number of unlit segments of the indicator bar is equal to or less than that of Gauge 2.
    The less the number of unlit segments of the indicator bar, the more the degree of ECO driving is. And the more the number of unlit segments, the less the degree of ECO driving is.
    PHEV-ECU judges the number of lighting segments according to the accelerator pedal angle and vehicle speed and transmits a CAN communication signal to the combination meter via CAN communication.
    The combination meter indicates the number of segments necessary for the ECO pedal guide, according to an ECO pedal guide signal.
    noteThe combination meter corrects the number of lighting segments according to a vehicle speed signal.
GAUGE2
  • The combination meter turns ON/OFF the Gauge 2 (guide line for ECO driving) according to a vehicle speed signal.
ECO DRIVE INDICATOR
  • The combination meter displays level of ECO drive in conjunction with ECO pedal guide.

ECO Drive Report
  • The ECO drive report is a function which displays the last five data of average fuel consumption, present fuel economy (present value), and the best fuel economy (highest value) on the information display by calculating and recording average fuel consumption.
  • The combination meter calculates the average fuel consumption according to the signal below, detects the status of ECO mode , and displays “ECO drive report” on the information display when the electric motor switch is turned ON→OFF.
