Drive to Calibrate Cameras On Tesla Model 3 

Model 3 must maneuver with a great deal of precision when Autopilot features are being used. Therefore, before some features (for example, Traffic-Aware Cruise Control or Autosteer) can be used for the first time or after certain Service repairs, the cameras must complete a self-calibration process. For your convenience, a progress indicator is displayed on the touchscreen.

Calibration typically completes after driving 20-25 miles (32-40 km), but the distance varies depending on road and environmental conditions. Driving on a straight road with highly-visible lane lines allows Model 3 to calibrate quicker. When calibration is complete, the Autopilot features are available for use. Contact Tesla only if your Model 3 has not completed the calibration process after driving 100 miles (160 km).

Note: If you attempt to use a feature that is not available until the calibration process is complete, the feature will not be enabled and the touchscreen displays a message.
Note: Model 3 must repeat the calibration process if the cameras are serviced by Tesla, and in some cases, after a software update.
