Modern vehicles are packed with safety technology that most drivers use without thinking about it, automatic emergency braking, lane departure warning, adaptive cruise control, blind spot monitoring. Collectively, these systems are called ADAS: Advanced Driver Assistance Systems.
What most people don’t realize is that these systems require periodic calibration to function correctly, and certain events can knock them out of calibration without you even knowing it.
How ADAS Works
ADAS systems rely on a network of cameras, radar sensors, ultrasonic sensors, and LiDAR to understand the vehicle’s surroundings. These sensors are calibrated to work at precise angles and distances. When the system is calibrated correctly, it knows exactly where the lane lines are, how far away the car in front is, and what’s in your blind spot.
When calibration is off, even slightly, the system can give false warnings, fail to warn when needed, or engage incorrectly. That turns a safety system into an unreliable one.
When Is ADAS Calibration Required?
After Windshield Replacement
This is the most common trigger. Most forward-facing cameras (the ones that power lane keeping assist, automatic emergency braking, and traffic sign recognition) are mounted directly to the windshield. When the glass is replaced, the camera’s position relative to the vehicle shifts, even slightly, requiring recalibration.
After a Collision
Any collision significant enough to require body work can shift sensors and cameras, even if they look undamaged. Bumper-mounted radar sensors and grille-mounted cameras are especially vulnerable.
After Wheel Alignment or Suspension Work
Some ADAS systems use the vehicle’s wheel alignment data as a reference. After alignment or major suspension changes, some systems need recalibration to account for the updated geometry.
After Replacing a Bumper
Forward and rear radar sensors are often built into the bumper assembly. Any bumper replacement requires sensor inspection and likely recalibration.
Static vs. Dynamic Calibration
Static calibration is done in the shop. Specialized targets are placed at specific distances and angles in front of (or around) the vehicle, and the system is calibrated against these targets. This requires a level surface, proper lighting, and precise measurement, not something that can be done in a parking lot.
Dynamic calibration requires driving the vehicle at specific speeds on roads with clear lane markings while the system calibrates itself. Some vehicles need both static and dynamic calibration.
Does Insurance Cover It?
Increasingly, yes. Many insurance companies now recognize ADAS calibration as a required part of windshield replacement and include it in claims. If your insurer is replacing your windshield, ask specifically about camera calibration coverage.
JR Car Care Does ADAS Calibration Right
We have the equipment and training to perform both static and dynamic ADAS calibration on most makes and models. If you’ve recently had your windshield replaced or been in a collision and aren’t sure whether calibration is needed, call us at (508) 820-0779. We’ll help you figure it out.
