ADAS Camera Calibration in Sanford, NC After New Glass

What the camera does

I-CAR, the collision repair training organisation, says forward-facing cameras control lane departure warning, collision braking and adaptive cruise control. The Insurance Institute for Highway Safety (IIHS) says lane departure warning systems use cameras to track the vehicle’s position in its lane, and that front crash prevention uses cameras, radar or lidar to detect the vehicle ahead, warn the driver and, in most systems, brake automatically if the driver does not respond.

These systems work. IIHS research found that forward collision warning with automatic braking cut rear-end crashes in half, and warning alone cut them by 27 percent. IIHS also reports that 20 automakers, representing 99 percent of U.S. light vehicle sales, committed to make front crash prevention standard, and that a federal rule finalised in 2024 will require it on nearly all new light vehicles by September 2029. On Lee County’s roads, that means more of the cars needing a windshield have a camera behind it every year.

Why new glass means a new calibration

The camera is fixed to a bracket bonded to the windshield. A new windshield brings a new bracket position, a slightly different angle and different glass in front of the lens. I-CAR lists removing the windshield, removing the rearview mirror and removing the camera itself as events that may require aiming the camera. Some manufacturers’ procedures name it directly: in I-CAR’s calibration search, the 2019 Subaru Forester’s EyeSight stereo camera requires calibration “If windshield is removed or replaced” and also “If wheel alignment is performed”.

I-CAR’s advice is to look up the manufacturer’s requirements for each vehicle, because they vary by year, make and model. That is part of why Impex orders by VIN: the VIN identifies the camera system as well as the glass.

Static and dynamic calibration

• Static calibration. One or more targets are placed at set positions in front of the car, and a scan tool starts the aiming procedure while the car stands still. It needs a level surface and a clear space in front of the car.
• Dynamic calibration. The car is driven on the road, sometimes connected to a scan tool, at or below a set speed for a set time or distance while the camera learns the road. I-CAR notes it may need roads clear of rain and snow, without heavy traffic or many curves.
• Both. Some cameras need a static calibration followed by a dynamic one.

Impex says its technicians complete both static and dynamic calibrations in one visit, and that calibration takes between 30 minutes and 2 hours depending on the make, the model and the type of system.

ADAS calibration in Sanford: where it happens

Impex says it performs ADAS calibration on site immediately after windshield replacement, so you are not sent to a dealership afterwards. Whether your car’s calibration can be done where it is parked, or needs more room or a flatter surface than the spot offers, depends on the manufacturer’s procedure, and Impex will tell you when you book. A dynamic calibration needs suitable roads, and around Sanford the straighter stretches of US 1 and US 421 are the kind of road the procedure asks for.

Signs the camera needs checking

• A driver-assist warning light on the dashboard after glass work, a wheel alignment or suspension work.
• Lane keeping that pulls toward one line or warns when you are centred.
• Collision warnings with nothing ahead, or adaptive cruise that loses the car in front.
• A change in ride height: new tires of a different size, a lift or lowering kit, or very uneven tire pressures. Impex notes that sensor alignment can be affected by changes in ride height or angle.

Who pays for calibration

When calibration is required after glass replacement, many insurers cover it under the same comprehensive claim as the glass. Impex advises confirming with your provider that both the glass work and the calibration are included under your policy. Under G.S. 58-3-180 you choose who does the work, and Impex works with all major insurance providers. See glass claims.

Radar is a separate job

Not every sensor is behind the windshield. Front radar usually sits in or behind the bumper or grille, and it is aimed after front-end work rather than after glass work. See radar sensor calibration.
