Calibrate cameras
Model 3 must maneuver with precision when using Autopilot features. Therefore, before certain features can be used for the first time or after certain types of service repairs, the cameras must complete a self-calibration process. For your convenience, the touchscreen displays progress indicators.
Once calibration is complete, the Autopilot features are available for use. Calibration is completed after approximately 20-25 miles (32-40 km) of driving but this may vary depending on the environment and road conditions. If you are driving on straight, multi-lane roads (such as a highway) with clear road markings (in both your own and adjacent lanes), calibration may complete faster. Contact Tesla if your Model 3 has not completed the calibration process after 100 miles (160 km) of driving.
If a camera has been removed from the location it was calibrated in (for example, if the camera or windshield has been replaced), the calibration must be removed. To do so, press Controls > Service > Camera calibration > Delete calibration. Once the calibration is removed, Model 3 performs the calibration again. Delete calibration is often helpful when recalibrating the cameras but it does not solve all camera and sensor problems.
Note: The cameras need clear road markings in both your own and adjacent lanes (at least two lanes on either side of the vehicle) to be calibrated. For best results, drive in the center lane of a low-traffic highway (preferably with at least five lanes) that has clear road markings.
Note: If you try to use a function that is not available before the calibration process is completed, the function will be disabled and a message will be displayed on the touch screen.
Note: Model 3 Will need to repeat the calibration process if the cameras are serviced by Tesla and in some cases after a software update.
