PG Recalibration

What is ADAS windscreen recalibration?

Vehicles nowadays come fitted with standard advanced driver assistance systems (ADAS). Mostly located or mounted on the windscreen, these front-facing camera sensors detect objects, cars, pedestrians or obstructions in your car’s forward view and gauge distance between your car and these objects or obstructions. These advanced driver assistance systems (ADAS) gather safety information around the vehicle to provide the driver with safety information around the vehicle to provide the driver with safety warnings.

The front-facing camera sensors include:

  • rain sensors
  • adaptive cruise control
  • automatic high beams
  • lane keeping assist
  • lane departure warning
  • forward-collision warning

It is important to calibrate the ADAS system back to its OEM specification after a windscreen replacement to ensure proper functioning of the system.

Sensor recalibration

Since the forward-facing camera and sensors are located on the windscreen itself, this means that when a windscreen with ADAS is replaced, there is a risk of misalignment that can greatly affect the system’s performance. Even a small misalignment of just a few millimetres can mean the difference between a vehicle avoiding a collision or not.

That’s why it is essential to ensure professional windscreen recalibration by certified technician after any windscreen replacement to guarantee the safe and efficient functioning of the ADAS system.

PG Glass technicians are fully accredited and authorised to work on an ADAS equipped vehicles and to calibrate the windscreen according to OEM Specifications.

We have over 30 Specialised Fitment Centres equipped with the latest advanced technology in ADAS calibration.


ADAS Recalibration falls under two categories:

At PG Glass we are equipped to cater for the recalibration of any Dynamic or Static Advanced Driver Assistance System on any make or model of car.

Dynamic Recalibration

This applies to dynamic ADAS and calibration that is carried out with the use of a hand-held device plugged directly into the car. In most cases, the vehicle will then need to be driven at a prescribed speed over a certain distance in optimum weather conditions, to allow the system to become accustomed to certain road features. Often the vehicle manufacturer will stipulate specific parameters for calibrating of their dynamic ADAS.

Static Recalibration

This applies to static ADAS and calibration is carried out in a workshop environment on a level surface. This form of recalibration requires specialist equipment like the CSC (Camera and Sensor Recalibration) Tool. Each car manufacturer requires different recalibration settings for their Static ADAS.


ADAS functionality will need to be recalibrated
What does ADAS mean for a customer and PG Glass?
When we replace a windscreen that is equipped with a camera-based system, the original position of the damaged glass is not easily maintained. Meaning the new glass does not sit in the same position, angle and depth in the vehicle aperture as the original factory-installed glass. The new position of the windscreen will then result in the camera sitting at a different angle than what was initially intended and will record the required information incorrectly thus affecting the system and putting the occupants, other motorists and you at risk when driving the vehicle.

Vehicles with the ADAS functionality will need to be recalibrated or calibrated (unless stated otherwise) after a replacement windscreen has been fitted. Recalibration of forward-facing ADAS cameras has been integrated into the PG way of Fitting.

Don’t place yourself at risk
If the camera or sensors are out by even a few millimetres, it can mean the difference between a vehicle avoiding a collision or not.
