Modern vehicles are equipped with increasingly advanced safety systems, many of which fall under the umbrella of Advanced Driver Assistance Systems (ADAS). These systems, designed to improve driver safety, include features like lane departure warning, adaptive cruise control, automatic emergency braking, and blind-spot detection. ADAS relies on sensors, cameras, and radar to function correctly, but what many drivers don’t realize is that these systems need regular calibration to work accurately. Top Notch Body Shop & Mechanic would like to dive into the importance of ADAS calibration, when it’s needed, and what you should know to keep your vehicle’s safety features in top shape.
What is ADAS Calibration?
ADAS calibration is the process of adjusting and fine-tuning the cameras, sensors, and radar systems that support advanced safety features in modern vehicles. Proper calibration ensures these systems work as intended, accurately detecting road signs, other vehicles, lane markings, and pedestrians. Over time, or after certain repairs, these sensors and cameras may become misaligned, which can lead to incorrect readings or faulty safety responses. Calibration repositions them to meet the original manufacturer’s specifications, so they perform with precision.
When is ADAS Calibration Needed?
There are several scenarios where ADAS calibration becomes necessary. Here are the most common:
• Windshield Replacement: Many ADAS features rely on a forward-facing camera mounted on or near the windshield. If the windshield is replaced or repaired, the camera may be slightly misaligned, necessitating recalibration to ensure accuracy.
• Collision Repair: A minor fender bender or more severe accident can shift the position of your ADAS sensors or cameras. Even a small misalignment can disrupt the system’s ability to function properly.
• Suspension or Alignment Work: Changes in your car’s suspension, alignment, or even tire replacement can affect the angles at which sensors and cameras capture information. Any change to the vehicle’s height or alignment should prompt an ADAS calibration.
• Bumper Replacement or Repair: Radar sensors are often mounted in the front and rear bumpers, and any work done on the bumper, whether it’s replacement or repair, can interfere with these sensors’ calibration.
• Battery Replacement or Disconnection: In some vehicles, disconnecting the battery or replacing it may interfere with the ADAS calibration settings. Always check your manufacturer’s recommendations after such replacements.
Why is ADAS Calibration Important?
ADAS calibration is essential for your vehicle’s safety features to function as designed. Here’s why it matters:
• Accuracy in Safety Features: Misaligned sensors and cameras can lead to inaccuracies in ADAS responses. For example, a miscalibrated forward collision warning might not alert you in time or, worse, could initiate emergency braking without cause.
• Driver & Passenger Safety: ADAS is designed to protect you and other road users. When these systems are accurately calibrated, they significantly reduce the risk of accidents by providing timely alerts and assistance.
• Avoiding False Alarms: A miscalibrated ADAS system may generate false alarms, leading to unnecessary warnings or incorrect adjustments while driving. This can be frustrating and may reduce your trust in the system, potentially affecting safe driving habits.
How Often Should You Have ADAS Calibrated?
ADAS calibration is typically required only after repairs, replacements, or modifications that could affect sensor alignment. There isn’t a set interval for regular ADAS calibration like an oil change, but it’s wise to check your vehicle’s owner manual or consult with a professional if you’re unsure. If you experience strange ADAS behavior, such as unexpected alerts or safety features not responding as they should, it’s a good idea to have the system checked and calibrated as necessary.
