ADAS calibration in Fayetteville, NC is the step after a windshield replacement that most drivers never hear about until they need it. ADAS means advanced driver assistance systems: the lane departure warning that chirps when you drift on I-95, the automatic braking that reacts to a stopped car on Skibo Road, the adaptive cruise that keeps a gap on the Outer Loop. Many of them look at the road through a camera mounted at the top of the windshield, behind the mirror. When the windshield changes, the camera has to be aimed again.

Fayetteville Auto Glass is Impex Auto Glass serving Fayetteville. Impex says it performs ADAS calibration on site immediately after windshield replacement. This page explains what the systems do, why a new windshield affects them, the two ways a camera is calibrated, how long it takes and how insurance treats it.
What ADAS does, and why it matters
The Insurance Institute for Highway Safety (IIHS) explains that front crash prevention systems use sensors such as cameras, radar or lidar to detect a vehicle ahead; they warn the driver, precharge the brakes, and most brake automatically if the driver does not respond. Lane departure warning systems use cameras to track the vehicle’s position in its lane. IIHS research found that forward collision warning with automatic braking cut rear-end crashes in half, and warning alone reduced them by 27 percent.
These systems are becoming universal. IIHS reports that 20 automakers, representing 99 percent of U.S. light vehicle sales, committed to standard front crash prevention, and that a federal rule finalized in 2024 requires it on nearly all new vehicles of 10,000 pounds or less by September 2029. More and more of the vehicles getting a new windshield in Fayetteville have a camera behind it.

Why a new windshield means ADAS calibration in Fayetteville, NC
I-CAR, the collision repair training body, says forward facing cameras control lane departure warning, collision braking and adaptive cruise control, and lists the events that may require aiming the camera: removing the windshield, removing the rearview mirror, or removing the camera itself. Its example for a 2019 Subaru Forester with the EyeSight stereo camera lists calibration if the windshield is removed or replaced and if a wheel alignment is performed.
The reason is geometry. The camera’s bracket sits on the glass. A new windshield, however well fitted, puts the camera at a very slightly different angle, and a fraction of a degree at the windshield is a large error a hundred yards down the road. Impex warns that incorrect calibration can make safety systems give false warnings or fail to detect obstacles.
Requirements vary by year, make and model, which is why I-CAR keeps an OEM calibration requirements search. Impex’s VIN check before a windshield job is also how it knows whether your vehicle has a camera that will need calibrating.
Static and dynamic calibration
| Static | Dynamic | |
|---|---|---|
| How | Targets placed in set positions in front of the vehicle; a scan tool runs the aiming procedure | The vehicle is driven at or below a set speed for a set time or distance, sometimes with a scan tool connected |
| Vehicle | Stationary | Moving |
| Needs | A level space with room in front of the vehicle | Roads clear of rain or snow, light traffic, few curves |
Some vehicles need one, some the other, and some need both, according to I-CAR. Impex says its technicians complete both static and dynamic calibrations in one visit, and that most calibrations take between 30 minutes and 2 hours depending on the make, model and type of system. Around Fayetteville, a dynamic calibration is a drive on roads like the All American Freeway or US 401 once the windshield adhesive is ready.
Other times your camera needs calibrating
Impex notes that a vehicle with lane keeping assist, adaptive cruise control or automatic emergency braking likely needs calibration after windshield replacement, accident repair or even suspension work. I-CAR’s Subaru example includes wheel alignment. If a warning light comes on, or the systems behave oddly after any of these, have the calibration checked. Impex also advises keeping the vehicle on a level surface and keeping proper tire pressure after calibration, since ride height and angle affect sensor alignment.
Radar is a separate system
Many vehicles also carry a forward radar sensor, which I-CAR says sits in or behind the front bumper or grille, not in the windshield. A windshield replacement on its own does not mean radar calibration. Bumper, grille and front-end work do: see ADAS radar calibration.
After the calibration
Impex advises that if you notice unusual ADAS alerts or the systems do not behave as they did, you should contact your service provider to recheck the calibration. Impex also advises keeping the vehicle on a level surface and keeping the tires at the right pressure, and give the windshield the 24 hours of care it needs: no car wash and no slammed doors.
Insurance and calibration
Impex says that when calibration is required after glass replacement, it is in most cases covered by comprehensive insurance along with the glass. Confirm with your insurer that both the windshield and the calibration are included under your policy. Under G.S. 58-3-180 you choose who does the work. More on the insurance and glass claims page.
Calibration is done as part of a windshield replacement in Fayetteville, NC by the mobile service at your address. A chip repair does not move the windshield, so a windshield repair does not need calibration.

Questions people ask
How do I know if my car has a camera that needs calibration?
If your vehicle has lane departure warning, lane keeping, automatic emergency braking or adaptive cruise, there is probably a camera at the top of the windshield behind the mirror. Impex’s VIN check before the job confirms it.
How long does ADAS calibration take?
Impex says most calibrations take between 30 minutes and 2 hours, depending on the make, model and whether it is static, dynamic or both.
Can calibration be done at my house?
Impex says it performs ADAS calibration on site after windshield replacement and completes static and dynamic calibrations in one visit. A level spot and correct tire pressure help.
What happens if the camera is not calibrated?
Impex warns that incorrect calibration can cause false warnings or a failure to detect obstacles. The systems may still switch on, which is why a missed calibration is easy to overlook.
