Safety Warning: Ensure the vehicle is in park and not in motion.

2. Soft Reset the Touchscreen

Locate the scroll wheels on the steering wheel.
Simultaneously press and hold both scroll wheels for approximately 10 seconds.
Release the scroll wheels once the Tesla logo appears on the screen.
Wait for the system to reboot and check if the screen functions correctly.
