Lane Departure Warning? Collision Alert System? Adaptive Cruise Control?

These high tech features that many newer vehicles have are designed for vehicle and driver safety. These precise systems rely on cameras and laser sensors that pass through your windshield. Below are a few facts about these Advanced Driver Assistance Systems (ADAS). Check out this video for more information about the importance of windshield calibration:

  • Fact: By 2020 over 40% of all vehicles will have this technology.
  • Fact: These systems save thousands of lives and billions of dollars
  • Fact: Windshield calibration requires special training and special calibration equipment.
  • Fact: Most vehicles with Advanced Driver Assistance Systems must be calibrated after various alterations such as windshield replacement.

Calibration and Windshield Replacement

Calibration is the process of returning a vehicle’s ADAS to original equipment or OEM specifications after a new windshield has been installed. Calibration is essential after a new glass installation, particularly a windshield with a camera mounted to it, to stay current with existing features and to certify that the ADAS features continue to function properly despite having been moved during windshield installation.

InterMountain Auto Glass can calibrate most vehicles to ensure that all laser and camera systems are operating correctly before and after your windshield replacement.

Many of the features that require calibration are auto detecting and alerts while the vehicle is in motion.

An Important Safety Measure

The installation of a new windshield, installed and calibrated by a certified technician, is a critical safety measure. Generally during a windshield install on an ADAS windshield, the camera(s) are removed and unplugged from their bracket and reattached and recalibrated. Even if camera is not unplugged or unhooked during the auto glass install, it is necessary to recalibrate to make sure the features are functioning properly for your safety.
