NOTICE:
When replacing the windshield glass of a vehicle equipped with a forward recognition camera, make sure to use a Lexus genuine part. If a non-Lexus genuine part is used, the forward recognition camera may not be able to be installed due to a missing bracket. Also, the dynamic radar cruise control system, front camera system, lane control system, road sign assist system, pre-collision system or lighting system (EXT) may not operate properly due to a difference in the transmissivity or black ceramic border.
