PRECAUTION FOR AUTOMATIC HIGH BEAM SYSTEM
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.
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.

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