Release the scroll wheels once the logo is visible.
Wait for the system to reboot, which may take a minute or two.

Ensure the vehicle is in "Park."
Disconnect the 12V battery to perform a complete power cycle:
- Open the front trunk (frunk) and locate the 12V battery.
- Use a socket wrench to disconnect the negative terminal first, followed by the positive terminal.
