        Destination Search Preset Destination Memory Search Sets a pre-registered point as a destination point while driving.
        Address Search Destination information can be entered in the following order: area, town name, street name and house number.
        Previous Destination Search Stores the coordinates, names, and dates of up to 100 locations that have been set as destinations.
        Online Database Destination Search The navigation system can use an internet search engine to set a destination using the most up-to-date information.
        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.

        Route Information Bar Display

        Displays the following information:


        • Street name of the current location

        • Distance and travel time to the destination

        • Distance to the destination and estimated time of arrival

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

        A004LY0E02
        Item Outline
        (1) Cruising Range Displays the approximate drivable distance.
        (2) Average Speed Displays the value that has been calculated by the combination meter assembly, which is based on the distance driven and the time elapsed since the ignition switch was turned to ON.
        (3) Average Fuel Consumption per Minute
        • 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), provided that the ignition switch is ON.

        • Displays the average fuel consumption for the last 15 minutes or since clear was last selected.

        (4) Elapsed Time Displays the 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.
        (5) Clear Switch Clears all of the past information.
        (6) Current Fuel Consumption per Minute 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), provided that the ignition switch is ON.
        (7) Best Fuel Consumption Displays the best (the most economical) fuel consumption per trip.
        (8) Average Fuel Consumption per Trip
        • Displays the current record and the last 5 average fuel consumption per trip 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.
