  2. 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.
      Forward recognition camera

      • When the forward recognition camera is deformed.

      • When the forward recognition camera is dirty.

      • When any other abnormal conditions exist with the forward recognition camera.
      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 has been modified.
      Automatic high beam system

        Malfunction:

      • When the automatic high beam indicator light changes from green to yellow.


      • 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. Precautions for replacing windshield


      1. The timing for switching high and low beams varies depending on the light transmission of the windshield, so be sure to replace the windshield with genuine parts.

      2. When performing removal, installation or replacement of the windshield glass, it is necessary to perform "Recognition Camera/Target Position Memory" and "Beam Axis Learning"

      3. When replacing the windshield glass of a vehicleequipped with a forward recognition camera, make sure to use a Toyota genuine part. If anon-Toyota genuine part is used, the forward recognition camera may not be able to beinstalled due to a missing bracket or the precollision system may not operate properly due to a difference in the transmissivity or blackceramic border.

      4. A01QOJB

        Do not attach items such as stickers (including transparent stickers) or an antenna to the windshield glass within the area shown in the illustration in front of the forward recognition camera.
