press and hold the power button for approximately 3-5 seconds until the system shuts down completely.

断电重启（最后手段）：

If the previous methods don't work, you can try cutting the power to the system.
Locate the negative terminal of the car battery, usually found under the hood or in the engine bay.
Disconnect the negative terminal carefully, using insulated tools to prevent electrical shock.
Wait for about 10 seconds to ensure all electrical components are fully discharged.
Reconnect the negative terminal and start the car. The infotainment system should restart automatically.

寻求专业帮助：

If the system still doesn't function properly after trying all the above steps, it's best to consult a professional. Contact your local Volkswagen dealership or a certified technician to have the system diagnosed and repaired.

Important Notes：

Always prioritize safety when performing these operations. Avoid damaging electronic components, especially when handling the battery.
Never attempt to restart the infotainment system while the vehicle is running, as this could interfere with driving performance and safety features.
Ensure the vehicle is parked in a safe location before performing any maintenance or repairs.
