Windscreen ADAS Calibration
ADAS Calibration After Windscreen Replacement
Many modern vehicles have cameras mounted behind the windscreen. After glass replacement, these systems may need recalibration so lane assist, emergency braking and camera-based safety features can operate correctly.
Why It Matters
Modern windscreens are part of the vehicle safety system
On many vehicles, the windscreen is more than just glass. Forward-facing cameras are often mounted behind it and used by driver assistance systems such as lane departure warning, lane keep assist, traffic sign recognition and autonomous emergency braking.
When the windscreen is replaced, the camera position, bracket, glass angle or optical view may be affected. Depending on the vehicle and manufacturer procedure, ADAS calibration may be required after the replacement.
Systems often linked to windscreen cameras
- Lane assist
- Lane departure warning
- Autonomous emergency braking
- Traffic sign recognition
- Adaptive cruise support
- Forward collision warning
When It Is Needed
When might windscreen calibration be required?
Calibration requirements vary by vehicle. Some vehicles require calibration after every windscreen replacement, while others depend on the fitted systems, repair method and manufacturer instructions.
Camera Calibration
Forward-facing camera calibration after glass replacement
The forward-facing camera needs a clear and accurate view of the road ahead. If its position, angle or view is altered during windscreen replacement, the vehicle may not interpret lanes, signs, vehicles or hazards correctly.
Windscreen ADAS calibration helps check that the camera-based system is aligned according to the relevant vehicle procedure.
- Camera position and view may be affected
- Calibration may be static, dynamic or combined
- Manufacturer procedures determine the correct method
- Diagnostic equipment may be required
- Suitable setup conditions may be needed
Calibration Methods
Static and dynamic windscreen camera calibration
The correct calibration method depends on the vehicle make, model, year and fitted ADAS system.
Static calibration
Static calibration usually uses specialist targets, diagnostic equipment and controlled setup measurements. The vehicle may need to be positioned carefully on level ground with enough space in front of it.
Dynamic calibration
Dynamic calibration involves driving the vehicle under specific conditions so the camera system can learn or verify alignment. Road conditions, speed and lane markings may matter.
Procedure-led calibration
The vehicle manufacturer procedure determines whether calibration is needed and which method should be followed. This is why the vehicle details are important when making an enquiry.

ADAS Connect can help private drivers, garages, bodyshops and windscreen companies route enquiries after windscreen replacement. The aim is to make the first step simpler by collecting the right information early.
If you are unsure whether calibration is needed, send the vehicle details, postcode and reason for enquiry. The vehicle and replacement details can then be assessed.
Useful details to include
- Vehicle registration
- Vehicle make and model
- Your postcode or town
- Whether the windscreen has already been replaced
- Any dashboard warning lights
- Whether this is a driver or trade enquiry
