Does my car need calibration after windshield replacement?



Should you be contemplating whether your vehicle necessitates calibration post windshield repair, Nuvision is readily available to assist. The simple answer is yes, your vehicle might indeed need calibration after having its windshield replaced. This is particularly the case for cars outfitted with advanced driver assistance systems (ADAS). Windshield calibration is a procedure that fine-tunes the parameters of a vehicle’s ADAS to ensure proper functionality. Features such as automatic braking, lane departure warnings, and adaptive cruise control heavily depend on sensors positioned on the windshield.


Upon replacing your windshield, these sensors could potentially be slightly moved or disturbed, thereby affecting their functioning. Consequently, it’s of utmost importance to calibrate your vehicle’s ADAS after a windshield replacement. It’s not just about assuring the system’s functionality, but it also pertains to securing your safety and that of others on the road.


What is ADAS calibration?

ADAS are intricate systems developed to warn drivers of potential dangers and in certain cases, make corrective action. For instance, should a vehicle veer off its lane, the lane departure warning system will notify the driver. If the car in front suddenly halts, the automatic braking system will engage. However, these systems require accurately aligned sensors to work efficiently. Even the slightest misalignment could jeopardize the system’s hazard detection capabilities. Therefore, recalibration is crucial following windshield replacement.


While windshield replacement is a routine repair, calibrating the ADAS is a specialized procedure. Not every auto repair shop possesses the required expertise or tools to carry out the calibration. Thus, it’s crucial to select a shop that is competent and experienced in ADAS calibration. Some vehicle manufacturers mandate a static calibration process, performed in a controlled setting and possibly taking several hours. Others might utilize a dynamic process where the vehicle is driven at a set speed on well-marked roads to recalibrate the systems.


Typеs of calibrations

Typically, there are two types of calibrations: static and dynamic.


Static calibration involves positioning a specific target image in front of the vehicle and using it to recalibrate the sensors. This method requires specialized settings and equipment, as any errors could result in incorrect calibration. It’s usually conducted indoors to prevent weather conditions from influencing the procedure. The vehicle must remain stationary, and the process could take several hours.


Dynamic calibration, on the contrary, entails driving the vehicle at a specific speed on a clearly marked road. The sensors are recalibrated by assessing real-world driving conditions. This requires a specialist to drive the vehicle and supervise the systems, and the process generally takes less time than a static calibration.


The type of calibration your vehicle needs is dictated by the manufacturer’s guidelines. Some vehicles might even necessitate a combination of both methods. It’s important to refer to your vehicle’s manual or consult a professional to comprehend the recommended calibration procedure for your specific model.


Remember, ADAS calibration isn’t a one-time process. Regular assessments and calibrations are required to ensure these systems continue to operate correctly, especially following significant events like a windshield replacement.


Importancе of Calibration

While it may appear to be an extra hassle and expense, neglecting to calibrate the ADAS post windshield replacement could result in serious repercussions. For instance, situations could arise where the automatic emergency braking system fails to initiate promptly, or the lane departure warning malfunctions, both of which could lead to accidents. Additionally, some insurance providers may not cover incidents if they discover that the ADAS wasn’t calibrated after a windshield replacement.


Furthermore, with the continuous evolution of vehicle technology, ADAS are becoming more prevalent. Numerous new vehicles come standard with these systems, and older models are frequently updated with them. As a result, windshield replacement procedures are likely to increasingly include ADAS calibration in the future. Therefore, it is paramount for every vehicle owner to understand the importance of calibration.



In summary, the necessity for calibration after windshield replacement goes beyond a mere technical requirement—it’s a crucial safety measure. Ensuring the proper operation of your vehicle’s ADAS is as vital as any other maintenance or repair task. While it may require some additional time and resources, the peace of mind that comes with knowing your vehicle’s safety systems are functioning as they should far outweigh the cost.

Remember, it’s always prudent to seek advice from a professional auto repair shop or your vehicle’s manufacturer if you have any queries or concerns regarding windshield replacement and ADAS calibration. Safe driving is a collective responsibility, and we all have a role to play in maintaining the safety of our roads for everyone.
