    6. Manual Headlight Beam Level Control System

      Component Function
      Headlight Leveling Switch The level of the headlight can be adjusted between 0 and 5, and a switch level status signal is sent to the headlight leveling motor.
      Headlight Leveling Motor Headlight leveling motors in accordance with signals from the headlight leveling switch and moves the reflector*1 / projector*2 up and down.

      *1: for halogen headlight

      *2: for projector headlight

  2. OPERATING CONDITION


    1. Daytime Running Light System


      1. The daytime running light system is enabled when the conditions given below are met:

        Condition Ignition switch is ON.
        Light control switch off or AUTO position (when taillight is not being controlled by the automatic light control).
        Engine is running.

    2. Flow Me Home System


      1. The follow me home system is enabled when the conditions given below are met:

        Condition Ignition switch is off.
        Light control switch off or AUTO position.
        Dimmer switch is pulled to flash headlights once.

  3. FUNCTION


    1. Light Automatic Turn-off System


      1. When the ignition switch is turned off while the light control switch (TAIL or HEAD) is turned on, the headlights and fog light are turned off automatically. When the ignition switch is turned off while the light control switch is in the AUTO position, all lights are turned off automatically.

        Light control switch position Outline
        AUTO While the lights (headlights, front fog lights, rear fog light and taillights) are turned on, this system automatically turns them off when the ignition switch is turned off.
        HEAD While the lights (headlights, front fog lights, rear fog light and taillights) are turned on, this system automatically turns off only the headlights and the front fog lights when the ignition switch is turned off.
        TAIL

      2. After the light automatic turn-off system was activated, when the ignition switch is shifted from ON to off while the light control switch (HEAD) is turned on or is in the AUTO position, the battery saving function turns off the headlights and taillights automatically in approximately 20 minutes. In addition, when one of the doors is opened from the closed status or closed from the opened status, the accumulated time is reset and the lights turn off in approximately 20 minutes after the door was opened/closed.

      3. The light automatic turn-off system is controlled by the main body ECU (multiplex network body ECU).

    2. Light Reminder System


      1. The light reminder system warns the driver using a buzzer when the meter ECU inside the combination meter assembly receives the driver's door courtesy light switch signal via the main body ECU (multiplex network body ECU) and the ignition switch is turned off and the door is opened with the taillights kept on. The buzzer is located inside the combination meter assembly.

        Light Control Switch Position Ignition Switch Door Buzzer
        TAIL, HEAD Switch off Open Sounds
        Closed -

    3. Manual Headlight Beam Level Control System


      1. The manual headlight beam level control system keeps the beam of the headlight adjusted. to the appropriate level in accordance with the number (weight) of passengers and volume of luggage.

      2. The headlight beam level can be adjusted from 0 to 5 by operating the headlight leveling switch.
