Any vehicle equipped with front-facing sensors or cameras requires a FULL CALIBRATION after a windshield replacement. Calibration cannot be completed on non-genuine windshields due to potential imperfections in the glass itself.
Windshields are an integral part of a vehicle. With advancements in Lexus safety technology & the development of Lexus Safety System as standard on nearly all new Lexus vehicles, it is imperative that should your windshield need to be replaced, it is replaced with a Lexus Genuine OEM replacement windshield.
Toyota, Lexus & Scion, Genuine windshields play an important role in the safety of the vehicle by providing structural rigidity, clarity, and integration with advanced vehicle technology. In addition, glass can play a critical role in noise dampening, UV protection, and general occupant comfort and safety. Toyota, Lexus & Scion Genuine Windshields often play a role in the operation of various electrical components such as heads up display, cameras for accident avoidance, rain sensors, antennas, and heating elements. Non-Genuine Windshields often do not account for these complex electrical components and may interfere with vehicle electronic systems, or cause these electronic systems to not function properly.
For these reasons, Lexus, a division of Toyota Canada Inc., does not support the use of Non-Genuine Windshields in a repair situation.
During windshield and fixed glass removal or replacement, it is crucial to follow proper installation procedures. These specific procedures are outlined in Toyota, Lexus & Scion model-specific Service Repair Manuals. The manuals provide detailed instructions and illustrations for removal and installation procedures for windshields and other glass in the vehicle. The repair manuals will also identify any single use parts that cannot be reused in this type of repair.
