Solution

1. Preparation

Ensure the vehicle is parked and turned on.
Verify that the battery level is sufficient (above 20%).
Have your Tesla account credentials ready in case a software recovery is needed.

2. Perform a Soft Reset

Sit inside the vehicle and close all doors.
Hold down both scroll wheels on the steering wheel until you see the Tesla logo appearing on the touchscreen.
Release the scroll wheels and wait for the system to reboot, which may take a minute.

3. Perform a Hard Reset (if necessary)

If the soft reset does not resolve the issue, proceed to a hard reset.
Press and hold the brake pedal while simultaneously performing the soft reset (holding both scroll wheels).
Continue holding the brake until the Tesla logo appears, then release both the scroll wheels and the brake.

4. Check for Software Updates

Once the system has rebooted, access the "Software" tab on the touchscreen.
Check for any available updates and ensure the vehicle is connected to Wi-Fi.
If an update is available, follow the prompts to download and install it.

5. Restore Settings (if needed)

If the system is still unresponsive or if settings were lost, log into your Tesla account via the mobile app or website.
Use the app to reset any specific settings or configurations that need to be restored.
