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, clearance lights, taillights and license plate lights.

  2. LIGHT AUTO TURN-OFF SYSTEM


    1. General

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

    2. When all of the following conditions are met, the headlights, front fog lights, taillights, clearance lights, license plate lights and rear fog lights turn off:


      • The ignition switch is turned from ON to off.

      • The headlights, front fog lights, taillights, clearance lights, license plate lights and rear fog lights are on.

      • The driver door is opened.

  3. 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 30000 V and applies it to the discharge bulbs in order to illuminate them.

  4. DAYTIME RUNNING LIGHT SYSTEM

    The daytime running light system is designed to automatically illuminate the daytime running lights (high-intensity clearance 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).

    • There are 2 LED type clearance light circuits in each headlight. One is for a conventional low-intensity clearance light that illuminates with the taillights, and the other is for the high-intensity clearance light that is used for the daytime running light system.

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


      • Engine is running.

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

      • Parking brake switch is off.
