Advanced Driver-Assistance Systems

Driving technology has grown leaps and bounds in the past decade. Front-facing cameras mounted on or near your windshield have become a common safety feature on modern cars and trucks. These cameras are part of your vehicle's Advanced Driver-Assistance System (ADAS) and are designed to protect you and your vehicle on the road. They utilize radar, lidar, cameras, computer imaging, sensors, networking, and other devices to help create a safer driving experience.

What is ADAS?

  • LDWS (Lane Departure Warning System)
  • ACC (Adaptive Cruise Control)
  • Blind Spot Monitoring
  • Collision Avoidance Brake Assist
  • Eyesite (Subaru) Brake Assist
  • Steering Assist
  • LKAS (Lane Keep Assist System)
  • Automated Parking
  • And Much More…

All vehicles with ADAS functions attached to the windshield MUST be recalibrated after a windshield replacement to ensure that the safety features continue to work as intended. At Capital Auto Glass we can complete a windshield replacement and ADAS calibration at the same time. Think of it like getting a new pair of glasses. Your eyes need to adjust to the new prescription in the same way the camera needs to make sure it can see through the new windshield properly.

"Another auto glass shop said that I do not need to have the camera recalibrated, that 'they never had a problem before'.

If you have lane departure warning as part of your ADAS functions, you know the car warns you when leaving the lane or approaching the lane markings. If someone does not properly perform your ADAS calibration after a windshield replacement, then there is a chance the car's system could fail to alert you or even alert you at the wrong time, causing you to make a quick decision based on false information. Another example: if the car's supposed to trigger emergency breaking in the event of a suddenly approaching object, a windshield with an improperly calibrated ADAS camera could bring the car to an abrupt stop at exactly the wrong moment. Or not at all. In most cases there are no warning signs or indicators when it is not working properly. Recalibrating is the ONLY way to know it is correct. Capital Auto Glass takes your safety serious. We have invested in the tools and training to make sure your vehicles ADAS systems are working properly when they leave our care.

Types of Calibration

  • Dynamic Calibration – This type of calibration requires driving the vehicle at a set speed on well-marked roads to recalibrate the camera system. Dynamic calibrations can take up to one hour in addition to the time it takes to replace the windshield.
  • Static Calibration – A specific target is required, usually an image mounted on a fixture in front of the vehicle during the recalibration process. Static calibration tests can take up to two hours in addition to the time it takes to replace the windshield.
  • Dual Calibration – Sometimes vehicles use a combination of both static and dynamic. These can take 3-4 hours of additional time after windshield replacement.

Capital Auto Glass can perform most Dynamic, Static and Dual system calibrations at our shop. These systems protect drivers through a range of capabilities, creating a circular safety net around the vehicle to help reduce the risk of collisions. Don't settle for another auto glass shop telling you the forward-facing camera "does not need to be calibrated." You can trust the professionals at Capital Auto Glass to perform the required and necessary procedures for your vehicle
