ADAS calibration

Re-aiming a car's safety cameras and radar after a repair or windshield replacement so features like emergency braking work correctly.

Also called: ADAS recalibration, sensor calibration, camera calibration

ADAS calibration is the process of aligning the cameras, radar and other sensors behind a car's driver-assistance features so they see the road where the software expects. A camera that is off by a fraction of a degree can misjudge distance or lane position, which can make automatic emergency braking or lane-keeping assist react late, early or not at all.

Calibration is often needed after a windshield replacement (forward cameras usually mount on the glass), bumper or grille repairs, a wheel alignment or an airbag deployment. Shops follow the automaker's procedures and use one of two methods: static calibration with targets set up in the shop, or dynamic calibration done on a test drive at specified speeds. Some vehicles need both.

For insurance, calibration is part of the cost of a proper repair and should appear on the estimate. Kentucky's glass statute, for example, covers camera recalibration along with no-deductible glass replacement, a version of full glass coverage. If an estimate leaves calibration out, ask the shop and the insurer why, and request documentation that it was done before you rely on the features again.
