Do I Need ADAS Calibration After Windshield Replacement?
How Windshield Replacement Affects ADAS
How Windshield Replacement Affects Your Safety Systems
If your vehicle has a camera or sensor mounted to the windshield, you need
ADAS calibration
after that windshield is replaced. Removing and reinstalling the glass shifts the camera's position by even a fraction of a degree, and that's enough to throw off features like lane-keeping assist or automatic emergency braking. Sierra Mobile Glass includes ADAS calibration as part of the windshield replacement process, so your specific vehicle leaves with its safety systems reading exactly as the manufacturer intended.

How Do I Know If My Vehicle Has a Camera That Needs Calibration?
The easiest way to check is to look at the area directly behind your rearview mirror. If you see a small housing or bracket mounted to the glass there, your windshield is almost certainly carrying an ADAS camera. Your owner's manual will also list which driver-assist features came on your specific trim, and a dashboard warning light for lane assist or collision warning after a repair is a strong sign calibration is needed.
Most vehicles built since around 2015 carry at least one of these systems, and newer trims often carry several. If you're not sure what your dashboard icons mean or whether your model year qualifies, our technicians can check your VIN and confirm before your appointment.
What Happens If I Skip Calibration on My Vehicle?
Skipping calibration doesn't disable your safety systems; it just means they may not be reading the road accurately anymore. That can show up as a delayed warning, a system that doesn't engage when it should, or a false alert that trains you to ignore real ones. We cover the specific risks in more depth in our What Happens If ADAS Calibration Is Skipped article if you want the full picture, but the short version for your own vehicle is simple: an uncalibrated camera is a safety system you can no longer fully trust.
Does It Matter Where I Get My Windshield Replaced?
It does, because calibration accuracy depends on the glass fitting exactly the way your manufacturer specified. Sierra Mobile Glass installs OEM-quality or better glass so your camera bracket sits in the correct position, and our ADAS calibration team holds I-CAR Platinum certification, the top tier for this specific work. We're also listed in the AGSC Safe Windshields Directory, which reflects the same installation standards that keep your calibration accurate the first time rather than requiring a second visit. You can read more about how calibration itself works on our
ADAS Calibration Knowledge page.
