ADAS calibration
Re-aiming driver-assistance cameras and radar after work that disturbs where they point.
Also called: camera calibration · radar calibration · windshield camera calibration
What it means
Definition
Driver-assistance features read the road through a camera behind the windshield and, on many cars, radar behind the grille or bumper. Both depend on knowing exactly where they are aimed, so replacing a windshield, grille or bumper can require the sensor to be recalibrated before the features work as designed. Which repairs require it, and how it is done, is set by each manufacturer for each system.
Why a buyer cares
What it changes
A camera left uncalibrated after glass work does not necessarily light a warning; the feature can stay switched on while reading the road from the wrong reference. A history showing a windshield or bumper replacement is worth a question about what was calibrated afterwards.
In practice
Where you meet it
As a separate line on a glass or collision invoice, reading camera calibration, radar calibration or ADAS calibration.
Two things that look alike
Not the same as
A wheel alignment sets the geometry of the wheels; this sets the aim of sensors.

The definition here is written from what the manufacturers’ own manuals say, but those documents could not be opened and quoted, so nothing is being presented as a citation. How we source data
NO CITABLE SOURCE YET. Toyota's owner's-manual PDF states the requirement but returns 403 to automated fetching, and Honda's techinfo manual pages could not be fetched either; a research agent quoted the Toyota text but it could not be independently confirmed here. The only NHTSA-hosted document found (an Audi TSB) does not state the rule. Do not publish this entry until a manufacturer page can be opened and quoted, or publish it with the empty-source notice the template already renders.
