        Tech Tips

        The items displayed differ by vehicle specification.

      6. Customize Display


        1. The customization display can be switched by pressing and holding the DISP switch for 0.8 seconds or more while the setting display is shown on the cruise information display.

        2. The customization item can be switched to by pressing the DISP switch for less than 0.8 seconds.

        3. The setting display can be switched to by pressing the DISP switch for 0.8 seconds or more while a customization item is being displayed.

        4. Settings can be changed by pressing the DISP switch for less than 0.8 seconds while the setting display is being shown.

        A01FPS1E01
        No. Condition
        *1 Pressing DISP switch for 0.8 seconds or more.
        *2 Pressing DISP switch for less than 0.8 seconds.

    3. ECO Lamp


      1. The operating diagram of ECO lamp is as follows:

        A01FP4QE02
        No. Condition
        *1 The opening illumination is turned on.
        *2 The ECO lamp illuminates 0% to 100% in accordance with driving conditions.
        *3 The ECO lamp illuminates 10%.
        *4 The ECO lamp illuminates 10% to 100% in accordance with driving conditions.
        *5 The ECO lamp illuminates 10% after the opening illumination is turned on.

    4. SPORT Lamp


      1. The operating diagram of SPORT lamp is as follows:

        A01FP8UE03

    5. Front Seat Belt Warning System


      1. When the power switch is on (IG), this system detects the condition of the seat belts based on the signals from the front seat inner belt assembly LH or RH and the occupant classification sensor.

      2. When the seat belt is unbuckled, the multi buzzer sounds 5 times 1.8 seconds after the power switch is turned on (IG). The multi buzzer sounds when the vehicle speed exceeds 20 km/h (12.4 mph) to emphasize the fact that the seat belt is unbuckled. After 9.6 seconds, the sound changes for emphasis. The sound continues for 20 seconds. Once the multi buzzer begins to sound, it will continue until the seat belt is buckled or the power switch is turned off.

        Tech Tips

        Upon receiving a request from a user who cannot wear a seat belt for a special reason, the multi buzzer warning can be canceled using a Global TechStream (GTS). For details, refer to the Repair Manual.

      3. Occupant Detection Sensor


        • The occupant detection sensor, which is enclosed in the seat cushion of the front passenger seat, is used to detect whether or not the front passenger seat is occupied.

        • This sensor consists of a construction in which 2 electrode sheets sandwich a spacer. When the occupant is seated, the electrode sheets come in contact with each other through the hole provided in the spacer portion, thus enabling the current to flow.

        • The sensor detects whether or not an occupant is seated in the front passenger seat.

  3. CONSTRUCTION


    1. Headup Display


      1. The headup display shows information on the windshield glass through the combination meter mirror ECU. The headup display gives the appearance of being displayed ahead of the vehicle.

        *1 Display Area *2 Windshield Glass
        *3 Combination Meter Mirror ECU - -

      2. By changing the angle of the concave mirror, the position of the image displayed can be adjusted.

        • The audio mode can be turned on or off by using a customize function.


          1. Press and hold the HUD switch (headup display main switch) for more than 3 seconds while the vehicle speed is 8 km/h (5 mph) or less.

          2. Change the display to audio display on/off mode if necessary (press and hold the HUD switch (headup display main switch) again for more than 1.5 seconds).

          3. Briefly press the HUD switch (headup display main switch) to turn the audio display on/off.
        Dynamic Radar Cruise Control Warning A01FPW6 Dynamic radar cruise control warning display indicates when the vehicle is nearing the vehicle ahead during the vehicle-to-vehicle control.
        Pre-crash Safety Warning A01FPJX The pre-crash safety warning display will interrupt the current information immediately when a warning occurs.
        Lane-keeping Assist Warning A01FPX2 The lane-keeping assist warning is displayed when the vehicle is out of its lane.

      4. The headup display undergoes the following transitions:

        A01FPHTE04
        No. Condition
        *1 Pre-crash safety warning display conditions from the driving support ECU assembly are not met.
        *2 Pre-crash safety warning display conditions from the driving support ECU assembly are met.

        *8 Pressing DISP switch (headup display main switch assembly) for less than 1.5 seconds.
        *9 Pressing the DISP switch (headup display main switch assembly) for 1.5 seconds or more when the vehicle speed is 8 km/h (5 mph) or less.
        *10 The vehicle speed is 8 km/h (5 mph) or more, or the headup display has not been operated for 3 seconds, or pressing DISP switch (headup display main switch assembly) for 1.5 seconds or more.
        *11 The audio system is operated.
        *12 The audio system has not been operated for 3 seconds.
        *13 There is a display request from the multi-media module display assembly.
        *14 There is no display request from the multi-media module display assembly.

      5. Customize Display


        • By pressing and holding the DISP switch (headup display main switch assembly) for 1.5 minutes or more, the headup display will be changed from normal mode to customize function mode. The following transitions will occur after entering customize function mode:

          *3 The vehicle speed is 8 km/h (5 mph) or more, or the headup display has not been operated for 3 seconds.

    2. Windshield Glass for Headup Display


      1. Windshield glass without a combiner treatment is used for the headup display.

      2. This glass has a wedge-shaped inner PVC film. This film, with its varying thickness, is located between the outer and inner layers of glass.

      3. The light that strikes the glass is reflected by the inner surface of the inner glass, and also by the inner side of the outer surface of outer layer of glass. With a conventional windshield, the light reflected from these 2 surfaces diverges due to the thickness of the glass, resulting in a double image.

      4. The PVC film uses its wedge shape to eliminate the reflection angle difference between the outer glass and inner glass. As a result, the reflected light is displaced to reduce double images.

      5. Thus, the reflected light from the headup display unit is recognized by the driver as a single display image.
