ODOMETER

The combination meter calculates mileage, based on the following signals and displays the mileage on the information display.

Signal name	Signal path
Ignition signal	—
Odometer signal	ABS actuator and electric unit (control unit) Combination meter

Indication Range

Odometer

0 km - 999999 km

DISTANCE TO EMPTY

The combination meter calculates distance to empty based on the following signals, and the calculated value is displayed on the information display.

Signal name	Signal source
Ignition signal	—
Fuel level sensor signal	Fuel level sensor unit Combination meter
Fuel consumption monitor signal	ECM Combination meter
Vehicle speed display signal	ECM Combination meter

note

Distance to empty on the information display is updated approximately every 30 seconds.
When the ignition switch is turned ON right after battery removal and installation, “−−−” is displayed until after a travel of 30 seconds.
The indicated values may not match each other when refueling with the ignition switch ON.

WARNING CONFIRMATION

The combination meter can cause an interrupt on the information display to indicate a warning, based on signals received from each unit and switch.
The indicated warning can be checked with “WARNING” during the satisfaction of an interrupt indication condition for each warning.

SETTINGS

The condition of following items can be set.

ASC Setting
Driver Assistance
ECO Mode Setting
TPMS Setting
Clock

TRIP COMPUTER

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.

Signal name	Signal source
Ignition signal	—
Fuel consumption monitor signal	ECM Combination meter
Vehicle speed display signal	ECM Combination meter

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.

Signal name	Signal source
Ignition signal	—
Fuel consumption monitor signal	ECM Combination meter
Vehicle speed display signal	ECM Combination meter

note	Average fuel consumption on the information display is updated approximately every 30 seconds. Soon after a reset or when the ignition switch is turned 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.

Signal name	Signal path
Ignition signal	—
Vehicle speed display signal	ECM Combination meter

note	Current vehicle speed on the information display is updated approximately every 0.3 seconds.

Average Vehicle Speed

The combination meter calculates average vehicle speed based on the following signals, and the calculated value is displayed on the information display.

Signal name	Signal source
Ignition signal	—
Vehicle speed display signal	ECM Combination meter

note	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 (ignition switch 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

ECM 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 ECM 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.
ECM 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.
note The 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.

Signal name		Signal path
Ignition signal		—
ECO pedal guide signal		ECM Combination meter

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 ignition switch is turned ON→OFF.
Signal name Signal path

Fuel consumption monitor signal ECM Combination meter
Vehicle speed display signal ECM Combination meter
ECO mode indicator signal ECM Combination meter

Signal name	Signal path
Ignition signal	—

AMBIENT TEMPERATURE

The combination meter calculates ambient temperature based on the following signals, and the calculated value is displayed on the information display.

Signal name	Signal path
Ignition signal	—
Ambient sensor signal	Ambient sensor Combination meter
Vehicle speed display signal	ECM Combination meter

note

The indicated temperature is corrected based on an ignition signal, ambient temperature detected by the ambient sensor, and vehicle speed signal. The indicated temperature is not raised under vehicle speed less than 20 km/h (12 MPH).
The ambient sensor input value that is displayed on “Data List” of M.U.T.-III SE is the value before the correction. It may not match the indicated temperature on the information display.
Depending on engine heat or heat on the road surfaces, an ambient temperature may be indicated higher than actual one.

CLOCK

The combination meter calculates time and displays it on the information display.

note	The settings screen of the information display allows the selection of time indication between 12-hour and 24-hour formats.

METER ILLUMINATION LEVEL

The combination meter displays the illuminance level of the back light on the information display by turning the illumination control switch.
