ADAS Systems & Why They Need Recalibration During Windshield Replacement in Bloomington & Terre Haute, IN

📍 Serving Bloomington, Terre Haute & the Wabash Valley

Modern vehicles are equipped with Advanced Driver Assistance Systems (ADAS) — safety features designed to help you stay in your lane, maintain safe distances, and avoid collisions. Many of these systems rely on cameras and sensors mounted directly to your windshield.

When your windshield is replaced, even a slight change in camera angle or position can disrupt how ADAS systems function. That’s why ADAS recalibration is essential for your safety after a replacement.

Here’s what you need to know about ADAS, how recalibration works, and why it’s required anytime your windshield is changed.

What Is ADAS?

ADAS refers to advanced driving safety technologies found in newer vehicles. These systems support safer driving by monitoring the road and assisting the driver in real time.

Common ADAS features include:

• Lane Departure Warning

• Lane Keeping Assist

• Forward Collision Warning

• Automatic Emergency Braking

• Adaptive Cruise Control

• Traffic Sign Recognition

• Driver Attention Monitoring

Most of these features rely on a forward-facing camera mounted to the windshield.

Why Windshield Replacement Requires ADAS Recalibration

Even if your new windshield is installed perfectly, the camera’s position changes by fractions of a millimeter — enough to cause:

• Incorrect lane detection

• Misread distances

• Delayed or false emergency braking

• Improper functioning of warning systems

• Inaccurate road sign readings

These safety systems must meet manufacturer specifications, and recalibration ensures they function exactly as intended.

How ADAS Recalibration Works

After windshield replacement, trained technicians perform one of two recalibration procedures depending on your vehicle:

1. Static Recalibration

Performed in a controlled environment using specialized equipment, calibration targets, and precise measurements.

2. Dynamic Recalibration

Done on the road by driving at specific speeds while the system relearns correct positioning.

Some vehicles require both procedures to ensure complete system accuracy.

What Happens If You Don’t Recalibrate?

Driving without recalibrating ADAS can lead to serious safety risks, including:

• Incorrect lane departure warnings

• Failure of automatic braking

• Inaccurate object detection

• Increased crash risk

• Warning lights or malfunction indicators

Skipping recalibration may also violate manufacturer requirements and compromise insurance coverage after an accident.

Does Insurance Cover ADAS Recalibration?

Yes, most comprehensive insurance policies cover recalibration costs when associated with a windshield replacement.
