The Lexus RX is equipped with an advanced Pre-Collision System (PCS) designed to enhance safety by detecting potential collisions and assisting the driver in avoiding accidents. When the windshield is replaced, it’s essential to recalibrate this system to ensure it functions correctly.

Why Calibration is Necessary

The PCS relies on sensors and cameras mounted near the windshield to monitor the road ahead. A windshield replacement can alter the positioning or alignment of these components, potentially leading to inaccurate readings or system malfunctions. Calibration ensures the sensors and cameras are properly aligned and synchronized with the vehicle’s onboard systems.

Steps to Calibrate the Pre-Collision System

  • Visit a Certified Lexus Service Center: Professional calibration requires specialized equipment and software that only authorized service centers possess.
  • Perform Diagnostic Checks: Technicians will connect the vehicle to diagnostic tools to assess the current state of the PCS and confirm the need for calibration.
  • Align Sensors and Cameras: Using alignment systems, the technician will adjust the sensors to the correct angles and positions.
  • Test the System: After calibration, the system will be tested to ensure it detects obstacles and functions as intended.

Attempting to skip or improperly perform calibration can compromise your vehicle’s safety features. Always rely on professionals to maintain the Lexus RX’s safety integrity after windshield replacement.
