From lane-keeping assist to forward collision warning, your car’s Advanced Driver Assistance Systems (ADAS) are designed to help prevent accidents. But here’s the catch: these systems don’t “self-correct” when something goes wrong.
Every ADAS feature depends on precise calibration of cameras, radars, and sensors. If any of them shift even slightly, your safety net is compromised. The question is—how do you know when your car needs ADAS calibration?
This blog will walk you through the most common situations and warning signs so you’ll know when it’s time to schedule a professional calibration.
When ADAS Calibration is Necessary
Calibration is not a one-time procedure. There are several scenarios where recalibration is required:
1. Windshield Replacement
If your vehicle has a forward-facing camera mounted behind the windshield, replacing the glass automatically requires recalibration. Even the smallest variation in angle can affect the system’s accuracy.
2. After an Accident
Even if the collision is minor, sensors and radars can shift. Cosmetic repairs alone aren’t enough—your ADAS must also be checked.
3. Suspension or Wheel Alignment Work
Any work that changes your vehicle’s geometry (alignment, ride height, suspension replacement) can impact calibration.
4. Module Replacement
If any ADAS component is replaced—such as a camera, radar, or control unit—it must be synced with the rest of the system through recalibration.
5. Bumper or Grille Replacement
Since many sensors are mounted in bumpers and grilles, any repair or replacement in these areas can disturb their alignment.
6. Roof or Side Mirror Repairs
Blind spot monitoring and 360° cameras often rely on sensors in mirrors or the roof area, requiring recalibration after repairs.
7. Daily Wear and Tear
Even without major work, everyday driving can gradually shift sensors due to potholes, vibration, or harsh conditions.
Warning Signs That Your ADAS May Be Misaligned
Not all issues are obvious. Watch for these common red flags:
- Dashboard warning lights related to ADAS.
- Lane departure alerts that trigger incorrectly.
- Blind spot monitoring failing to detect vehicles or giving false warnings.
- Adaptive cruise control not maintaining proper distance.
- Parking sensors beeping randomly or missing obstacles.
- Forward collision system activating late—or not at all.
- A “drift” feeling when lane-keeping assist is active.
If you experience even one of these issues, it’s time for calibration.
Why Ignoring Calibration is Dangerous
Many drivers think of ADAS as “extra help” rather than a critical safety system. But misalignment can create real hazards:
- False sense of security – You assume the system will respond, but it may fail.
- Increased accident risk – Late or incorrect warnings reduce reaction time.
- Insurance complications – Claims may be denied if calibration was neglected after repairs.
- Vehicle value impact – Buyers and dealerships expect properly functioning ADAS systems.
Ignoring calibration isn’t just risky—it can be costly.
Static vs. Dynamic Calibration
ADAS calibration is performed in two main ways:
Static Calibration
- Done in a workshop or lab using targets and specialized equipment.
- Precise and controlled environment.
- Often required after windshield or bumper replacement.
Dynamic Calibration
- Performed while driving under specific conditions (speed, distance, weather).
- The system “learns” by interacting with real-world road conditions.
- Often required for lane departure and adaptive cruise systems.
Some vehicles require both methods depending on the manufacturer.
How Often Should Calibration Be Done?
While there isn’t a universal mileage-based rule, most experts recommend:
- Every time one of the above scenarios occurs (repairs, replacements, collisions, alignments).
- Regular checks during routine maintenance—especially if your car frequently drives on rough roads.
- Whenever performance feels “off.”
Think of calibration like an eye exam for your car—it ensures your ADAS sees the road clearly.
Benefits of Regular Calibration
- Peace of Mind – Confidence that your systems will respond correctly.
- Accident Prevention – Properly calibrated ADAS has been proven to reduce accidents significantly.
- Cost Savings – Avoid unnecessary repairs, accidents, and insurance issues.
- Resale Value – Well-maintained ADAS systems increase your vehicle’s value.
Conclusion
Your ADAS systems are only as good as their calibration. Windshield replacement, accidents, suspension work, or even daily wear can throw sensors off—and you may not even realize it.
If you notice warning signs or have had recent repairs, don’t wait. Schedule a professional calibration to ensure your vehicle’s safety systems are functioning exactly as intended.
At Majster ADAS Calibrations, we use the latest tools, certified technicians, and manufacturer-approved processes to keep your ADAS working with pinpoint accuracy.
Because when it comes to road safety, “almost accurate” isn’t good enough.
