LIGHTING SYSTEM SYSTEM DESCRIPTION


  1. AUTOMATIC LIGHT CONTROL SYSTEM

    When the light control switch is in the AUTO position, the automatic light control system detects ambient light levels and controls the low beam headlights, parking lights, taillights, license plate lights and side marker lights.

  2. LIGHT AUTO TURN-OFF SYSTEM (except European Models)

    The light auto turn-off system is used to prevent the exterior lights from being accidentally left on (low beam headlights, high beam headlights, front fog lights, rear fog lights, taillights, parking lights, license plate lights and side marker lights).

    When all of the following conditions are met, the exterior lights turn off:


    • The engine switch is turned from on (IG) to off.

    • The headlights, front fog lights, rear fog lights, taillights, parking lights, license plate lights and side marker lights are on.

    • The driver door is opened.

  3. LIGHT AUTO TURN-OFF SYSTEM (for European Models)

    The light auto turn-off system is used to prevent the exterior lights from being accidentally left on (low beam headlights, high beam headlights, front fog lights, rear fog lights, taillights, parking lights, license plate lights and side marker lights).

    The lights that will turn off will vary as shown in the table below, according to the position of the light control switch.

    While the exterior lights are turned on, this control automatically turns off only the low beam headlights, high beam headlights and the front fog lights when the engine switch is turned from on (IG) to off.

    Tech Tips

    Taillights, parking lights, license plate lights, side marker lights and rear fog lights remain on.

  4. DAYTIME RUNNING LIGHT SYSTEM

    The daytime running light system is designed to automatically illuminate the daytime running lights during the daytime to make the vehicle more visible to other vehicles.


    • This system is controlled by the main body ECU (multiplex network body ECU) and engine room junction block assembly. The main body ECU (multiplex network body ECU) transmits a turn on signal to the engine room junction block assembly, which illuminates the high-intensity parking lights.

    • This system is enabled when the following conditions are met:


      • Engine switch is on (IG)

      • Engine speed signal is input (engine running)

      • Light control switch is in the off or AUTO position (and the low beam headlights are not turned on via the automatic light control system).

  5. HID HEADLIGHT SYSTEM

    The High Intensity Discharge (HID) headlight system uses a discharge bulb as its light source for the low beam. Discharge bulbs are superior to halogen bulbs.


    • Discharge bulbs have the following features:


      • The light emitted by the bulb is close in color to sunlight. The light shines ahead over a broader area and further forward, increasing the area visible to the driver.

      • Less power is consumed.

    • This system consists of the discharge bulbs and light control ECUs.

    • The light control ECU transforms voltage that is received from the battery to high voltage of up to 22000 V and applies it to the discharge bulbs in order to illuminate them.

  6. DOOR MIRROR FOOT LIGHT SYSTEM


    1. General


      • The door mirror foot light system consists primarily of the fade-in/fade-out function and timer illumination function.

      • This control is controlled by the outer mirror control ECU assembly for each mirror and main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) sends door mirror foot light on/off demand signals to the outer mirror control ECU assembly. According to various information, the outer mirror control ECU assembly performs fade-in/fade-out control of the door mirror foot lights.

    2. The door mirror foot light system has the following control functions:

      Function Outline
      Actuation Area-linked

      When all of the following conditions are met, the lights that operate turn on:


      • The engine switch is off.

      • All doors are closed.

      • A key is detected in the actuation area.

      When the following condition is met, the lights that operate turn off:


      • A key is not detected in the actuation area.
      Door Unlock-linked

      When all of the following conditions are met, the lights that operate turn on:


      • The engine switch is off.

      • All doors are closed.

      • Any door is unlocked when all doors are locked.
      Door Lock-linked

      When either of the following conditions is met, the lights that operate turn off:


      • All doors are locked when all doors are closed and any door is unlocked.

      • All doors are locked again when all doors are closed and locked.
      Engine Switch-linked

      When the following condition is met, the lights that operate turn off:


      • The engine switch is on (IG).
      Delay

      When approximately 15 seconds elapse after any of the following conditions are met, the lights that operate turn off:


      • An actuation area-linked function is used.

      • The door unlock-linked function is active.

      • Any door is opened and then closed.

  7. WELCOME LIGHTING SYSTEM


    1. When the wireless door unlock operation or the entry door unlock operation is performed at nighttime, the parking lights illuminate for 17 seconds.

  8. FOLLOW ME HOME SYSTEM (for European Models)


    1. The follow me home system is designed to illuminate the low beam headlights, taillights and parking lights for approximately 30 seconds after the vehicle is parked.


      1. This system is controlled by the main body ECU (multiplex network body ECU).

      2. This system is enabled when the following conditions are met:


        • The engine switch is off.

        • The light control switch is in the off or AUTO position.

        • The light control switch is pulled to flash headlights once.
