| Blind Spot Detection | Warns you of vehicles or objects in your blind spot. |
| Automatic Emergency Braking | Applies brakes automatically to avoid a collision. |
| Parking Assistance | Helps you park the car by guiding you or controlling the car itself. |
| Traffic Sign Recognition | Detects and displays traffic signs for the driver. |
Understanding these features can help you recognize when something isn’t working as it should, thus making it easier to determine when calibration might be necessary.
What’s Calibration, Anyway?
Calibration in the context of ADAS involves realigning sensors, cameras, and radars to ensure they function accurately. Each component of your vehicle’s ADAS needs to be perfectly aligned and set to the manufacturer’s specifications. This is crucial for these systems to interpret data correctly and provide accurate assistance.
Types of Calibration
There are generally two types of ADAS calibration:
| Calibration Type | Description |
|---|---|
| Static Calibration | Performed in a controlled environment, usually involves special equipment and targets. |
| Dynamic Calibration | Done while the vehicle is in motion, requiring driving at specific speeds on certain types of roads. |
Both types of calibration have their own pros and cons and are often dictated by the vehicle manufacturer.
Why is Calibration Important?
You might be wondering, “Why go through the trouble of calibrating ADAS?” Well, the importance cannot be overstated:

The Signs Your ADAS Might Need Calibration
Understanding the signs indicating the need for ADAS calibration can save you a lot of trouble down the road. Here are some common indicators:
Warning Lights
Modern vehicles come equipped with dashboard lights specifically for ADAS. If one or more of these lights are illuminated, it’s a clear indicator something is wrong. Here’s a rough guide:
| Light Indicator | Possible Issue |
|---|---|
| Lane Departure Warning Light | The lane-keeping assist system may be malfunctioning. |
| Blind Spot Detection Light | Sensors in the rear-view mirrors might be misaligned or damaged. |
| Adaptive Cruise Control Light | The radar may need calibration or repair. |
Performance Issues
Unusual behavior in ADAS features can also serve as a red flag:
- Lane Keeping Assist: If the vehicle starts giving lane departure alerts when you are clearly within your lane, calibration might be needed.
- Adaptive Cruise Control: Sudden changes in acceleration or braking without reason can be a sign.
- Parking Sensors: Inconsistent beeps or failure to detect objects accurately might require attention.
Recent Repairs or Modifications
Even seemingly minor incidents can knock your ADAS out of alignment, here are some scenarios:
- Windshield Replacement: Most ADAS cameras are mounted on or near the windshield. A replacement often necessitates calibration.
- Collision Repairs: Any work involving the front, rear, or sides of the vehicle can misalign sensors.
- Suspension Work: Changes in the vehicle’s height can affect sensor alignment.
When to Get Your ADAS Calibrated
