        Point Of Interest Search

        A destination can be set in 4 ways:


        • By selecting a category and then a location.

        • By entering a name and then selecting a location.

        • By selecting a POI on the map.

        • By using the online search through connected services.

        Map Search A destination can be set by scrolling the cursor on the map.
        Address Book (Memory Point) Search A destination can be set from the registered Address Book (Memory Point).
        Coordinate Search A destination can be input by entering its coordinates.
        Route Search Multiple Destination Setting Multiple destinations can be set. The sequence of the destinations can be rearranged as well.
        Search Condition Designation Searches for fast, short and ecological routes.
        Destination Reordering Changes the order of destinations when more than one destination is selected.
        Detour Search Changes the route to detour around a section of the route.
        Avoidance Area Searches for a route that avoids a designated area.
        Auto Avoid Traffic Search Automatically changes to another route to avoid heavy congestion.
        Guidance Voice Guidance Provides voice guidance about the distance and the direction of travel to a destination point based on road conditions and vehicle speed.
        Next Turn Guidance Provides guidance about the distance to the next turn and indicates the direction of the turn using an arrow.
        Motorway Exit or Junction Display When the vehicle approaches an exit or junction, the motorway guidance screen will be displayed.

    2. Fuel Consumption Screen


      1. The fuel consumption screen is displayed as illustrated below. This screen has the display functions listed below:

        A01UWX8E02
        Item Outline
        (1) Average Speed Displays an average speed value that has been calculated by the combination meter assembly, which is based on the distance driven and time elapsed since the ignition switch was turned to ON.
        (2) Range Displays the approximate drivable distance.
        (3) Past Record Switch Changes to the Past Record (per trip) fuel consumption screen.
        (4) Energy Switch Changes the screen to the energy monitor screen.
        (5) Average Per Minute Fuel Consumption
        • Displays the value that has been calculated by the combination meter assembly, which is based on the driven distance and the volume of fuel consumed (fuel injection signal) since the ignition switch was turned to ON.

        • Displays the average fuel consumption for the last minute, or since clear was last selected.

        (6) Recovered Energy
        • Indicates the recovered energy for 1 minute with "E" symbols.

        • The recovered energy status is calculated by the power management control ECU.

        (7) Elapsed Time Displays an elapsed time value that has been calculated by the combination meter assembly, which is based on the time elapsed since the ignition switch was turned to ON.
        (8) Clear Switch Clears all past information.
        (9) Current Per Minute Fuel Consumption Displays the instantaneous (current) fuel consumption value that has been calculated by the combination meter assembly, which is based on the driven distance and the volume of fuel consumed (fuel injection signal) since the ignition switch was turned to ON.
        (10) Best Fuel Consumption Displays the best (most economical) per trip fuel consumption.
        (11) Trip Information Switch Changes to the average per minute fuel consumption screen.
        (12) Average Per Trip Fuel Consumption
        • Displays the current record and the last 5 average per trip fuel consumption records or the current record and those since clear was last selected.

        • Starts calculating the average fuel consumption when the average fuel consumption displayed on the combination meter assembly is reset.

        (13) Update Switch
        • Restarts calculation of the average fuel consumption value.

        • Sends the average fuel consumption reset signal to the combination meter assembly to update the graph.

        (14) Energy Monitor

        Indicates the energy transmission direction, making it possible to confirm the current drive method (engine, motor or both), the power generation status by the engine and status of regenerative energy use.


        • The State Of Charge (SOC) of the battery can be checked on the meter. The meter shows the SOC in 9-levels.

        • Display the energy monitor status that has been calculated by the power management control ECU.
