Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked safely with the ignition off.
Tools Required:
- Torx screwdriver set
- Multimeter (for battery checks)

2. Software Update

Access the vehicle's settings and navigate to "Software."
Check for updates and install if available.
Restart the infotainment system after the update.

3. Soft Reset

Hold down the two scroll wheels on the steering wheel.
Wait for the screen to turn black and then release the wheels.
Allow the system to reboot fully.

4. Battery Inspection

Open the front trunk (frunk) and locate the 12V battery.
Use a multimeter to check the battery voltage; it should be around 12.5V or higher.
If voltage is low, consider charging or replacing the battery.

5. Main Battery Disconnect (if necessary)

Ensure vehicle is off and parked safely.
Remove the frunk cover to access the main battery terminals.
Disconnect the negative terminal first, followed by the positive terminal.
Wait for 5-10 minutes, then reconnect the terminals in reverse order (positive first, then negative).
Replace the frunk cover securely.
