Solution

1. Preparation

Ensure the vehicle is parked on a level surface and is in "Park."
Confirm that the battery is charged to at least 20% to avoid shutdown during calibration.

2. Update Software

Navigate to the "Software" tab on the touchscreen.
If an update is available, initiate the update process by following on-screen prompts.
Wait for the update to complete, which may take some time.

3. Reset the Autopilot System

Press and hold both scroll wheels on the steering wheel until the touchscreen resets (about 10 seconds).
Wait for the Tesla logo to appear and then release the scroll wheels.

4. Calibrate Cameras

Drive the vehicle in an area with clear lane markings, ideally at a speed of 25 mph or higher for at least 10 minutes.
Allow the vehicle to automatically recalibrate its cameras; this process may take several minutes and requires straight, clear roads.

5. Adjust Autopilot Settings

Access the "Autopilot" menu in the settings.
Ensure all desired features (e.g., Auto Lane Change, Traffic-Aware Cruise Control) are toggled on.
Make any necessary adjustments to the following settings based on user preference.

6. Final Verification

Perform a test drive on a highway or open road to confirm that autopilot features are functioning correctly.
Monitor the responsiveness of the steering and lane-keeping assistance.
