  3. PRECAUTION FOR AUTOMATIC HIGH BEAM SYSTEM


    1. General Description

      The automatic high beam system is a system that helps ensure visibility by automatically turning the high beams on and off. In addition, due to control limitations of the automatic high beam system, it may be necessary to manually turn the high beams on and off. For safety reasons, make sure to turn the high beams on and off manually according to the driving conditions.

    2. Conditions Unsuitable for Using Automatic High Beam System

      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. Manual operation should be considered.

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

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

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

      • When the front windshield is cracked.

      • When the front windshield is fogged-up.

      • When the front 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

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

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

      • When the camera sensor in the inner rear view mirror assembly is dirty.

      • When any other abnormal conditions exist with the inner rear view mirror assembly or its built-in camera 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 areas where the conditions often change between bright and dark.

      • When driving on hilly roads.

      • When driving on winding roads or around sharp curves.

      • When driving on bumpy roads (cobblestone paving, gravel roads, rough unpaved roads, 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 (posture has changed due to the vehicle being fully loaded, a trailer being towed, road conditions etc.).

      • When the vehicle has other malfunctions or it has been modified.
      Automatic high beam system

      Malfunction

      When the indicator on the combination meter assembly is off or is blinking.

      Others


      • When the automatic high beam system does not seem to be turning the high beams on and off properly.

      • When the automatic high beam system is frequently turning the high beams on and off.

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

    3. Windshield Replacement Precautions

      The timing of the high beams turning on and off differs depending on the light transmission rate of the glass. For this reason, when replacing the windshield, replace it with an original equipment part.

    4. Inner Rear View Mirror Assembly Handling Precautions

      Failure to observe the following precautions may result in a malfunction:


      • Do not touch the lens of the camera (built into the inner rear view mirror assembly) with bare hands.

      • Do not allow anything to adhere to the camera lens (built into the inner rear view mirror assembly).

      • Do not apply strong impacts to the inner rear view mirror assembly.

      • Do not allow any liquids to contact the inner rear view mirror assembly.

    5. AFS ECU (Headlight Swivel ECU Assembly) Replacement Precautions

      When replacing the AFS ECU (headlight swivel ECU assembly), it is necessary to synchronize the vehicle information and initialize the AFS ECU (headlight swivel ECU assembly).
