How often does ADAS need to be calibrated?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
ADAS calibration is event-based, not time-based. It is needed when something disturbs the camera’s aim — a windshield replacement, collision repair, wheel alignment or suspension change, camera removal, or a fault code. There is no mileage interval or expiry date. Between those events, the camera stays calibrated and needs no routine recalibration.
When does ADAS need recalibration
- After a windshield replacement — the camera was removed and refitted with the glass.
- After collision or body repair that touched the camera or its mounting.
- After a wheel alignment or suspension change that shifted the vehicle’s direction of travel.
- After the camera itself is removed or replaced for any reason.
- When a fault code or warning light points at the camera’s aim.
Does ADAS calibration expire
Calibration does not expire on a calendar. The camera’s aim is set when it is calibrated, and it holds until something physically changes it — the glass coming out, the camera moving, the vehicle’s tracking shifting. A camera calibrated correctly last year is still calibrated this year if none of those events happened.
That is why there is no mileage interval for recalibration, the way there is for an oil change. The trigger is an event, not a date. If a warning light appears, or if work was done that could disturb the aim, that is when a recalibration is on the table — otherwise, the camera keeps its verified aim.
Does ADAS need regular calibration — myths
ADAS should be calibrated at every service.
Calibration is event-based. With no event that disturbed the camera, there is nothing to recalibrate, and a routine service does not call for it.
Calibration wears out over time.
The aim holds until something physical changes it. Time alone does not shift a camera that was calibrated correctly.
A warning light is the first sign calibration is needed.
A light is one sign, but events like a windshield replacement or suspension work call for calibration before any light appears.
More questions about calibration frequency
Does ADAS need regular calibration?
No. It is event-based — needed when the camera’s aim is disturbed, not on a schedule. A windshield replacement, collision repair, alignment, or camera removal is the trigger.
When does ADAS need recalibration if nothing is wrong?
Only after an event that could shift the aim — a replacement, body work, or a suspension change. With no event, the camera holds its verified aim.
Does a tire rotation require ADAS calibration?
Usually not. A rotation does not change the camera’s aim. A change in tire size or a major suspension adjustment could, and those are the events that call for a check.
