Google RatingMost often, the camera behind your new windshield needs calibration — $250–$350 at our shop — but calibration is not the only possible cause. The safest next step is to have the system checked and confirm that the vehicle manufacturer’s required procedures were completed. Call (773) 227-5200 and we will check your vehicle’s requirement.
How does the windshield affect lane assist?
Many vehicles use a camera near the rearview mirror to read lane markings. Depending on the vehicle, that information supports lane departure warnings, lane keeping assistance and other safety features.
Replacing the windshield can affect the camera’s mounting position or view. Calibration aligns the camera according to the manufacturer’s procedure so it can interpret that view correctly.
Does every vehicle need calibration?
No single rule applies to every car. Requirements depend on the manufacturer, model, year and equipment. Some vehicles require calibration after windshield replacement even if the camera appears unchanged and no warning light is showing.
Honda Sensing, Toyota Safety Sense and Subaru EyeSight are examples of systems that may use windshield-mounted cameras. The specific procedure must be checked for your vehicle—not just the brand name.
What should you do if lane assist is unavailable?
- Do not rely on lane assist or other affected driver-assistance features.
- Check the owner’s manual for the warning’s meaning and safety instructions.
- Contact the shop that replaced the windshield and ask whether calibration was required and completed.
- Have persistent warnings or unusual behavior professionally checked.
Avoid trying to test lane assist by drifting out of your lane. Stay in control of the vehicle at all times.
Could something else cause the problem?
Yes. Dirty glass around the camera, poor visibility, unclear lane markings, system settings or a separate fault can also make lane assistance unavailable. A warning does not automatically prove the windshield installation was incorrect.
That is why checking the cause matters more than simply clearing the message. Likewise, the absence of a warning does not prove that required calibration has been completed.
