        *9 Taillight and Stop Light *10 Backup Light
        *11 Turn Signal Light - -

    2. Daytime Running Light System


      1. The daytime running light system is designed to automatically illuminate the daytime running lights, during the daytime to keep the vehicle highly visible to other vehicles.

    3. High Intensity Discharge (HID) Headlight System


      1. The HID system uses a metal halide bulb as the light source for each low beam. Discharge bulbs are superior to halogen bulbs.

    4. Automatic High Beam System (Models with Automatic High Beam System)


      1. The automatic high beam system detects lights in front of the vehicle and automatically changes between high beams and low beams to support the driver during night driving.

  3. MAIN FEATURES


    1. HID headlight system has the following features.


      1. The light emitted by the bulb is close in color to sunlight. The light shines ahead over a broader area and farther forward compared to halogen headlight system, increasing the area visible to the driver.

      2. Less power is consumed.

      3. HID headlight system has a bi-function mechanism. The bi-function mechanism increases the upper illumination area of the discharge bulb (low/high beams) when the high beams are turned on.

  4. PRECAUTION


    1. High Intensity Discharge (HID) Headlight System


      1. When the HID headlights illuminate, a high voltage (approximately 30000 V) is applied momentarily to the bulb sockets. Never connect a tester to the high voltage socket of a HID headlight for measurement, as this may lead to a serious accident because of high voltage.

      2. Whenever inspecting the HID headlight system, make sure that water or rain is not present, the light control switch is off, the battery terminal is disconnected, and the connector of the light control ECU is disconnected in order to prevent an electric shock.

      3. Whenever operating the HID headlights, make sure that it is done only after assembly has been completed and never operate the system without bulbs installed.

      4. Do not operate the HID headlights using a power source other than the vehicle's.

      5. When there is a defect in an HID headlight or any shock has been applied to it, replace the bulb with a new one.

      6. A discharge bulb reaches a high temperature when it is illuminated. For this reason, the life of the bulb could be shortened if any oil comes in contact with the glass portion of the bulb. Do not touch the glass portion of a bulb with bare hands.

    2. Automatic High Beam System


      1. The automatic high beam system is a system that helps ensure visibility by automatically changing the high beams on and off.

      2. However, due to control limitations of the automatic high beam system, it may be necessary to manually change high beams on and off. When driving, for safety reasons, make sure to switch the high beams and low beams manually according to the driving conditions.

      3. Under the following conditions, the automatic high beam system might not detect other vehicles or lights correctly, or the high beams might cause glare or flash pedestrians or the occupants of other vehicles. Manually operation should be considered.

        Factor Condition
        Weather/Climate When driving in bad weather (rain, snow, fog, sandstorms, etc.).
        Windshield

        • When the windshield is not clear (ice, snow or frost on the glass).

        • When the windshield is dirty (sand, mud, water stain or bugs on the glass).

        • When the windshield is cracked.

        • When the windshield is fogged-up.

        • When the windshield has a film attached.

        • When an object on the instrument panel reflects off of the front glass.

        • When any other abnormal conditions exist with the front glass.
        Inner Rear View Mirror Assembly (Automatic High Beam Sensor)

        • When a parking tag, magnifying lens or other accessory is mounted on the inner rear view mirror assembly.

        • When the inner rear view mirror or its built-in camera is deformed.

        • When the automatic high beam sensor in the inner rear view mirror is dirty.

        • When any other abnormal conditions exist with the inner rear view mirror or its built-in automatic high beam sensor.
        Nearby Vehicles or Lights

        • When lights similar to headlights or taillights are in the vicinity of the vehicle.

        • When a nearby vehicle has no lights or its lights are off.

        • When a vehicle in front has misaligned lights, or its lights are changing color.

        • When a vehicle in front has extremely dirty headlights or taillights.
        Road Conditions

        • When driving in an area where the conditions often change between bright and dark.

        • When driving on a road with many uphill and downhill slopes.

        • When driving on a winding road or around a sharp curve.

        • When driving on a bumpy road (cobblestone pavement, gravel road, rough unpaved road, etc.).

        • When highly reflective objects are in front of the vehicle (mirrors, road signs, etc.).
        Own Vehicle

        • When the headlights are damaged, deformed or dirty.

        • When the vehicle posture is abnormal flat tire (posture has changed due to the vehicle being fully loaded, a trailer being towed, road conditions, etc.).

        • When the vehicle has other malfunctions or if the vehicle has been modified.
        Automatic High Beam System

        Malfunction:


        • When the automatic high beam indicator light on the combination meter assembly is blinking.

        Others:


        • When the automatic high beam system does not seem to be changing between the high beams and low beams properly.

        • When the automatic high beam system is frequently changing between the high beams and low beams.

        • When the glare from the high beams would disturb pedestrians or the drivers of other vehicles.

    3. Automatic Headlight Beam Level Control System


      1. When the headlights are on, the automatic headlight beam level control system operates the headlight level actuator in accordance with movement of the vehicle. The system operates once during loading and once vehicle reaches a steady state at speeds above 30 km/h (19 mph).

    4. Automatic Light Control System


      1. When the light control switch is in the AUTO position, the light control sensor detects the ambient light level and automatically turns the headlights, taillights and license plate lights on or off accordingly.

      2. This system is controlled by the main body ECU (driver side junction block assembly).

    5. Light Automatic Turn-off System


      1. The light automatic turn-off system is used to prevent the driver from leaving the vehicle with the headlights, front fog lights, taillights, or license plate lights on.
