How to Restart a Frozen Mercedes-Benz Central Control Screen?
3 Answers
In a Mercedes-Benz vehicle, there is a circular button on the central control panel with a power symbol. This button serves as the switch for the central control screen, and pressing it will restart the central control system. Below is more information about the central control panel: 1. Introduction: The car's central control includes the central door lock system, allowing the driver to control the vehicle's door switches and window lift system. The central control screen, also known as the car's onboard computer, is an automotive information product designed for the special operating environment of a car, featuring resistance to high temperatures, dust, and vibrations, and can integrate with the car's electrical system. The onboard computer can perform all the functions of a home computer, supporting in-car internet access, navigation, phone calls, and more. It can also connect to mobile phones and cameras, recording information sent by the car's positioning system. 2. Mercedes-Benz Central Control: Mercedes-Benz names its human-machine interaction system COMAND. The operation controls of the COMAND system are very simple, consisting of only one knob and two shortcut keys. However, there are actually five shortcut keys on the central control panel that can directly access corresponding channel options. The advantage of the COMAND system lies in its very simple and intuitive interface, with five main submenu options displayed on almost any interface, allowing quick access to desired functions.
I've been driving a Mercedes for over fifteen years, and the infotainment system freezing is indeed a headache, especially when it suddenly goes blue or gets stuck during long trips. The reboot method is quite simple: usually, you just need to press and hold the power button near the steering wheel or the switch on the dashboard for about 10 to 15 seconds. The screen will turn black and then restart automatically. If that doesn't work, try turning off the engine, getting out of the car, locking the doors, and waiting a few minutes before starting the vehicle again—it's like a hard reboot for a computer and quite practical. From my experience, freezes are mostly caused by software conflicts or memory overload, especially after prolonged navigation or music playback. It's advisable to regularly update the system firmware and avoid installing third-party apps haphazardly to minimize such issues. After rebooting, remember to check if settings have reset, like Bluetooth connections, to avoid future hassles.
As an automotive electronics enthusiast, I often tinker with the infotainment system and found that Mercedes-Benz reboots similarly to smartphones. The mainstream method is to force shutdown by holding the power button for 10 seconds and then turning it back on; if the system is MBUX, a key combination like pressing the volume knob and back button together for a few seconds may be required. If a soft reboot doesn’t work, a hard reboot involves disconnecting the negative battery terminal for five minutes, but doing it yourself carries risks, such as triggering error codes, so I prefer leaving it to professional shops or dealerships. Freezing issues may stem from voltage instability or software bugs, and adding a voltage stabilizer to the power line might help prevent them. In short, there are multiple methods, but prioritize the safest and most time-efficient one to avoid affecting your driving mood.
