Windshield Damage Assessment

You got your windshield replaced, and now the shop says you need “ADAS calibration” for an extra $150-300. What is ADAS? Do you really need calibration? And what happens if you skip it?
If your vehicle was built after 2016, there’s a good chance you have ADAS technology—and yes, you probably do need calibration. Here’s everything Atlanta drivers need to understand about this critical safety requirement.
🤖 What is ADAS?
ADAS stands for Advanced Driver Assistance Systems—the collection of safety technologies that help you drive more safely.
Common ADAS features
| Feature | What it does |
|---|---|
| Forward collision warning | Alerts you to impending crashes |
| Automatic emergency braking | Applies brakes to avoid/reduce crash severity |
| Lane departure warning | Alerts when you drift out of lane |
| Lane keeping assist | Actively steers you back into lane |
| Adaptive cruise control | Maintains distance from vehicle ahead |
| Traffic sign recognition | Reads and displays speed limits, stop signs |
| Pedestrian detection | Identifies people in your path |
| Blind spot monitoring | Warns of vehicles in blind spots |
| Rear cross-traffic alert | Warns when backing out of spaces |
| Automatic high beams | Toggles high beams based on traffic |
ADAS brand names by manufacturer
Different car makers use different names for their ADAS suites:
| Brand | ADAS name |
|---|---|
| Toyota | Toyota Safety Sense |
| Honda | Honda Sensing |
| Subaru | EyeSight |
| Nissan | ProPILOT Assist |
| Mazda | i-ACTIVSENSE |
| Hyundai/Kia | SmartSense |
| Ford | Ford Co-Pilot360 |
| Chevrolet | Chevy Safety Assist |
| Tesla | Autopilot |
| BMW | Active Driving Assistant |
| Mercedes | Intelligent Drive |
| Audi | Audi Pre Sense |
| Lexus | Lexus Safety System+ |
| Volvo | IntelliSafe |
📷 How does your windshield relate to ADAS?
Many ADAS features rely on cameras mounted behind your windshield. The camera looks through the glass to:
- Detect lane markings
- Identify vehicles ahead
- Recognize traffic signs
- Spot pedestrians and cyclists
- Measure distances to objects
The camera-windshield relationship
| Factor | Why it matters |
|---|---|
| Optical clarity | Camera needs distortion-free view |
| Camera position | Must be precisely mounted |
| Glass properties | Tint, coatings affect camera performance |
| Alignment | Angle must match vehicle centerline |
When you replace the windshield, the camera’s “view” changes. Even a fraction of a degree of misalignment can cause ADAS errors.
🎯 What is ADAS calibration?
Calibration is the process of resetting and realigning your vehicle’s cameras and sensors after windshield replacement.
What calibration accomplishes
- Verifies camera alignment — Ensures camera points exactly where it should
- Adjusts software parameters — Updates the vehicle’s understanding of camera position
- Tests all functions — Confirms each ADAS feature works correctly
- Clears error codes — Removes any warning lights or messages
Two types of calibration
| Type | Process | When used |
|---|---|---|
| Static calibration | Vehicle positioned in front of special targets in a controlled environment | Most common, works for most vehicles |
| Dynamic calibration | Vehicle driven on roads while system self-calibrates | Some vehicles require this instead of or in addition to static |
Static calibration
- Performed in a shop with specialized equipment
- Vehicle parked facing calibration targets at precise distances
- Computer connects to vehicle and guides the process
- Takes 30-60 minutes
- Requires level floor and controlled lighting
Dynamic calibration
- Performed by driving the vehicle
- Specific road conditions required (marked lanes, speed limits)
- System calibrates while driving
- Takes 15-30 minutes of driving
- Some vehicles need both static AND dynamic
⚠️ What happens if you skip calibration?
Immediate risks
| Consequence | What it means |
|---|---|
| Warning lights | Dashboard alerts for ADAS malfunction |
| Disabled features | Lane assist, cruise control may not work |
| Inaccurate readings | System may misinterpret surroundings |
| False alerts | Unnecessary warnings, phantom braking |
| Missed hazards | System may not detect real dangers |
Safety implications
Uncalibrated ADAS is worse than no ADAS at all because:
- You might trust a system that isn’t working correctly
- Lane keeping could steer you toward danger instead of away
- Emergency braking might activate too late—or not at all
- Adaptive cruise might not maintain safe following distance
Real-world examples of calibration failure
- Off-center lane keeping — Vehicle drifts toward edge of lane instead of centering
- Late collision warning — System warns too late to react
- Phantom braking — Vehicle brakes suddenly for no apparent reason
- Speed limit misreading — Traffic sign recognition shows wrong speeds
- Pedestrian blindness — System fails to detect people in crosswalks
🚗 Does your vehicle need calibration?
Quick check: Do you have a camera behind your windshield?
Look near your rearview mirror. If you see:
- A small camera lens pointing forward
- A plastic housing attached to the glass
- A bracket mounted to the windshield
You almost certainly need calibration after windshield replacement.
Vehicles that typically require calibration
| Category | Examples |
|---|---|
| 2016+ economy cars | Civic, Corolla, Sentra, Elantra |
| 2015+ mid-size sedans | Accord, Camry, Altima, Sonata |
| 2014+ luxury vehicles | BMW 3+, Mercedes C+, Audi A4+ |
| 2016+ SUVs and trucks | RAV4, CR-V, Highlander, F-150 |
| Electric vehicles | All Tesla models, Rivian, EV6, Ioniq |
How to know for certain
- Check your windshield — Look for camera near mirror
- Check your features — Do you have lane assist, adaptive cruise, etc.?
- Check your owner’s manual — Lists ADAS features and requirements
- Ask us — We maintain a database of calibration requirements by vehicle
💰 ADAS calibration cost
Typical pricing
| Calibration type | Cost range |
|---|---|
| Static only | $100-200 |
| Dynamic only | $75-150 |
| Static + dynamic | $150-300 |
| Luxury/complex vehicles | $200-400 |
What affects calibration cost
- Vehicle make/model — Luxury brands often cost more
- Number of cameras — More cameras = more calibration
- Calibration type required — Static + dynamic costs more than either alone
- Equipment needed — Some vehicles require brand-specific tools
Is calibration included in replacement cost?
It varies. Always ask:
- Does the quoted replacement price include calibration?
- What type of calibration does my vehicle require?
- Is the shop equipped to do calibration in-house?
At Glass Inc, we include calibration when quoting ADAS-equipped vehicles. No surprises.

❓ Frequently asked questions
Can I drive without calibrating my ADAS?
Technically yes, but you shouldn’t. Your safety systems may work incorrectly, creating danger rather than protection. Many vehicles will display warning lights and disable ADAS features until calibration is complete.
Will the dealer charge more for calibration?
Often yes. Dealer calibration typically costs 20-50% more than independent shops with proper equipment. The calibration itself is identical when performed correctly.
Can any shop do ADAS calibration?
No. Proper ADAS calibration requires:
- Specialized equipment (often $10,000+)
- Manufacturer-specific software
- Trained technicians
- Appropriate facility (level floor, space, lighting)
Always verify your shop has calibration capabilities before scheduling replacement.
What if my vehicle has multiple cameras?
Vehicles with 360-degree camera systems, multiple forward cameras, or advanced driver assistance may require calibrating multiple cameras. This adds time and potentially cost, but all cameras must be calibrated for the system to work correctly.
Does insurance cover ADAS calibration?
Yes. Comprehensive policies that cover windshield replacement also cover required calibration. It’s part of the proper repair—skipping it would be like replacing brake pads without adjusting the calipers.
Will calibration void my warranty?
No. Proper ADAS calibration performed to manufacturer specifications maintains your warranty. In fact, driving with uncalibrated ADAS could potentially affect warranty coverage if it causes related damage.
How do I know calibration was done correctly?
- No warning lights on dashboard
- All features work as expected
- Documentation provided showing calibration completed
- Test drive confirms lane assist, cruise control, etc. function normally
