Advanced Driver Assistance Systems (ADAS) are crucial for vehicle safety, enhancing driver awareness and reducing the likelihood of accidents. However, for these systems to function properly, they must be precisely calibrated. ADAS calibration ensures that sensors, cameras, and radar systems are aligned correctly to provide accurate data for features like lane departure warning, adaptive cruise control, and automatic emergency braking. But when should you get your ADAS calibrated? Below are the key situations when calibration is necessary.
1. After Windshield Replacement
One of the most common reasons to calibrate ADAS is after a windshield replacement. Many modern vehicles have forward-facing cameras mounted on the windshield that play a critical role in lane-keeping assistance, traffic sign recognition, and collision avoidance.

Even minor misalignment can lead to incorrect readings, increasing the risk of accidents.
-
Dynamic and static calibrations are often required to restore camera accuracy after a windshield change.
2. Following a Collision or Minor Accident
Even a minor accident can affect the alignment of ADAS sensors. A small fender-bender or curb impact may shift the positioning of cameras, radar, or LiDAR sensors.
-
Sensors need to be recalibrated to ensure they accurately detect obstacles and vehicles.
-
Even if no visible damage is present, unseen misalignments could impair ADAS functionality.
3. After Suspension or Wheel Alignment Adjustments
Changes to a vehicle’s suspension, ride height, or wheel alignment can affect the angles at which ADAS sensors and cameras detect their surroundings.
-
Modifications such as lifting or lowering a vehicle may require recalibration to maintain proper system functionality.
-
Even routine wheel alignments can shift sensor positioning, making calibration essential.
4. When ADAS Warning Lights Appear
Many modern vehicles have dashboard indicators that alert drivers when there is a potential ADAS malfunction.
-
If warning lights related to lane departure, collision avoidance, or adaptive cruise control appear, it may signal that calibration is needed.
-
Ignoring these alerts can compromise safety and lead to system failure in critical moments.
5. After Bumper or Body Repairs
Rear-end collisions or any repairs involving the front or rear bumpers can affect radar and sensor alignment.
-
Adaptive cruise control, parking sensors, and blind-spot monitoring rely on precisely positioned radar units.
-
A recalibration ensures these systems function correctly post-repair.
6. Regular Maintenance and System Updates
Some manufacturers recommend periodic ADAS calibration, even if no visible issues exist.
-
Software updates can change how sensors process information, requiring recalibration for optimal performance.
-
Regular inspections can help catch minor misalignments before they become safety risks.
7. When Replacing Tires with Different Sizes
If you upgrade or change tire sizes, it can impact how ADAS systems interpret speed, distance, and road positioning.
-
Larger or smaller tires alter the vehicle’s height and alignment, affecting sensor accuracy.
-
Calibration ensures features like adaptive cruise control and lane-keeping assist function properly.
8. When Experiencing Unusual ADAS Behavior
If your vehicle’s ADAS features start behaving inconsistently—such as false alarms, delayed responses, or failing to engage—it may indicate misalignment.
-
Unusual lane departure warnings or erratic braking could be signs of incorrect sensor readings.
-
A professional calibration check can restore proper system function.
Conclusion
ADAS calibration is a crucial step in maintaining vehicle safety and performance. Any changes to the vehicle’s structure, alignment, or sensor positioning can affect ADAS accuracy. Regular inspections, prompt recalibration after repairs or modifications, and attention to warning signs help ensure that these advanced safety systems continue to function correctly, keeping drivers and passengers safe on the road.
