Car owners sometimes face issues with their vehicles not performing as expected. One fact to note is that ADAS (Advanced Driver Assistance Systems) needs recalibration after repairs, even small ones such as windshield replacements, to maintain crash avoidance features.

This article will guide you on how ADAS calibration influences your car’s performance and safety. Keep reading to understand more.

Key Takeaways

  • ADAS calibration adjusts your car’s sensors and cameras, making sure safety features such as lane assist and automatic braking work correctly. This helps your car perform better and helps keeps you safe on the road.
  • Even small changes to your vehicle, such as fixing a broken windshield, can mess up how its advanced safety systems work. That means these systems must be recalibrated after repairs to avoid accidents.
  • Regular checks of ADAS systems are important for keeping them working right. If not calibrated properly, there’s a bigger chance of car accidents happening.
  • Professional calibration services can make sure your vehicle’s safety systems meet manufacturer standards. Choosing qualified experts helps to ensure that all parts of the ADAS are accurately adjusted.
  • Most windshield replacement companies can also re-calibrate your vehicle’s ADAS- making it a convenient one-stop-shop.
  • Advanced technology is making it easier to calibrate ADAS accurately, improving vehicle safety and performance further as cars become more automated.

Introduction to ADAS:

Advanced Driver Assistance Systems (ADAS) have become increasingly common in modern vehicles, enhancing both performance and safety. However, many car owners are unaware of the importance of ADAS calibration and how it impacts their vehicle’s functionality. This article will explore the significance of ADAS calibration, the challenges it presents, and how to ensure proper calibration for optimal vehicle performance and safety.

It’s imperative you understand what ADAS features your vehicle is equipped with and not equipped with, as well as how these systems function. This will help ensure your safety as each vehicle’s functionality varies. It’s also important that these systems are never relied upon for safety and should not be substituted for safe driving habits.

Understanding ADAS Calibration:

ADAS calibration involves adjusting and aligning the sensors and cameras in a vehicle to ensure that advanced driver assistance systems function accurately. This process is crucial for maintaining the proper operation of features such as lane-keeping assist, automatic emergency braking, and adaptive cruise control. Even minor repairs or modifications to a vehicle, such as changing tire size or fixing a bumper, can affect the accuracy of these systems, necessitating recalibration.

Possible Effects of Incorrect ADAS Calibration:

Improper ADAS calibration can lead to reduced vehicle performance and an increased risk of accidents. Misaligned sensors may cause issues with acceleration, braking, and overall handling, compromising the effectiveness of safety features such as blind-spot monitoring or emergency braking systems. Studies have shown that a significant portion of vehicles with ADAS repairs experience system issues, highlighting the importance of post-repair calibration.

Challenges in ADAS Calibration:

Maintaining accurate ADAS calibration can be difficult due to the complexities of automated driving systems and the precision required. Alterations to the position or angle of a sensor, such as changes when remounting from an old windshield to a new windshield, can impact the accuracy of ADAS sensors. Ensuring precise calibration is challenging and requires specialized tools and expertise.

Opportunities in ADAS Calibration:

Despite the challenges, emerging trends in ADAS calibration present opportunities for advancements in vehicle safety and performance. Technology plays a vital role in improving calibration accuracy, with innovations in lidar, radar, and software enabling more precise adjustments. The growing demand for ADAS calibration services also presents opportunities for the aftermarket sector to cater to the unique needs of an aging vehicle fleet.

Ensuring Proper ADAS Calibration

To help ensure proper ADAS calibration, have a professional perform regular checks and maintenance, and seek professional calibration services. This will help to maintain the optimal functionality of safety systems and enhance vehicle performance.

Regular checks and maintenance

Regular checks and maintenance of ADAS systems are crucial for ensuring their optimal functionality, vehicle performance, and occupant safety. The following practices can help professionals ensure the proper calibration of your vehicle’s Advanced Driver Assistance Systems:

  1. Conduct routine inspections of sensors, radars, cameras, and other ADAS components to ensure they are functioning correctly.
  2. Regularly check and maintain tire pressure and tread depth as these factors can impact the accuracy of ADAS features such as lane departure warning systems.
  3. Keep the vehicle’s front bumper, grille, and windshield free from debris or damage that could obstruct or impair the function of ADAS sensors.
  4. Ensure that the vehicle’s windshield is well-maintained to prevent any distortion that could affect ADAS sensors.
  5. Seek professional calibration services through your local glass shop periodically to ensure that all ADAS features are aligned with manufacturer specifications and operating at their best.


Proper ADAS calibration is crucial for maintaining vehicle performance, safety, and compliance with manufacturer specifications. As advanced driver assistance systems become more prevalent, understanding the importance of calibration and addressing the challenges it presents will be essential for ensuring optimal functionality and helping to reduce the risk of accidents. By staying informed and seeking professional services when necessary, vehicle owners can harness the full potential of their ADAS-equipped vehicles, contributing to enhanced safety on the roads.


1. What is ADAS calibration, and why is it important for my car?

ADAS calibration adjusts the sensors and cameras in your car’s advanced driver assistance systems (ADAS) such as lane departure warning (LDW) and automatic parallel parking. It’s crucial because it helps these systems work correctly, helping to make your car safer to drive.

2. How does ADAS improve vehicle safety?

By using features such as blind spot monitoring, lane-keep assist, and backup cameras, ADAS helps prevent accidents. For example, if you’re drifting out of your lane without signaling, the lane departure system can alert you or even steer you back to safety. Note that not all vehicles are equipped with this feature and not all features function the same.

3. Can calibrating my car’s ADAS affect its performance?

Yes! Properly calibrated ADAS ensures that systems work as intended by the original equipment manufacturer (OEM), which can enhance both performance and safety.

4. Do all cars have ADAS features?

Not all cars come with advanced driver assistance systems. Typically, newer models especially premium or luxury vehicles, are more likely to have them. Features vary across different brands and might include options from simple tire maintenance reminders to complex semi-self-driving capabilities. To ensure safety, be familiar with what features your vehicle has.

5. Will recalibrating my vehicle’s ADAS change how it drives on highways or during parking?

Recalibration fine-tunes your vehicle’s systems according to specific standards set by the original equipment manufacturer (OEM) for optimal performance—this could mean better handling during highway-speed drives with accurate speed limit sign recognition and, at low speed, smoother automatic parking experiences.
