What happens if you do not calibrate after a windshield replacement?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
The camera keeps working off an aim that no longer matches the road, so lane keeping may drift, automatic braking may respond late, and the systems may switch off with a warning light. The risk is that they still appear to work but read the road at the wrong angle. Calibration is what verifies they still see correctly.
What happens if you don’t recalibrate a windshield
- A lane-keeping or camera warning light on the dash
- The system has detected that its aim is off and disabled itself rather than steer wrong.
- Lane keeping drifts or pulls to one side
- The camera is reading the lane at an angle, so the assist corrects toward the wrong line.
- Automatic braking feels late or over-eager
- The camera’s distance reading is skewed, changing when and how the system intervenes.
- Adaptive cruise keeps too much or too little distance
- The camera’s view of the vehicle ahead is misaligned, which calibration is meant to correct.
Is it safe to skip calibration
Skipping calibration does not break the camera — it leaves it unverified. The systems may still switch on and behave as if they are working, which is exactly the problem: a lane-keeping assist that steers toward the wrong line, or an automatic brake that fires a beat late, looks like a functioning system until the moment it is not. Calibration is the step that confirms the aim matches the road.
The manufacturer requires it for a reason. The camera was removed and refitted with the glass, and its aim moved with that work. Driving on an uncalibrated camera means trusting safety systems that were never checked after they were disturbed.
If a problem appears after Skyview calibrates
When a camera warning light or lane-keeping issue shows up after Skyview’s calibration, Skyview comes back and redoes it — the aim is not settled until the systems read the road correctly.
More questions about skipping calibration
Can you drive without ADAS calibration?
The car will drive, but the driver-assist systems are unverified. The safer question is whether you want lane keeping and automatic braking acting on an aim nobody checked — and the manufacturer’s answer is no.
Will the car tell me if calibration is off?
Sometimes. A warning light is a clear signal, but a camera can also be misaimed without triggering one, which is why the check is done with a scan tool rather than waiting for the dash to complain.
Does skipping calibration void the warranty?
The manufacturer’s replacement procedure includes recalibration when a camera is behind the glass, so skipping it is departing from that procedure. Skyview includes calibration as part of the job and backs the work with a lifetime warranty tied to the VIN.
