The switch for the central control display screen is located on the central control panel, featuring a circular icon. Below is relevant information about the central control screen: 1. Functions of the central control screen: volume buttons, multimedia menu, audio menu, shortcut keys, back button, automatic parking, parking radar switch, etc. 2. Precautions for operating the central control screen while driving: When there is a passenger in the front seat, let them operate the central control buttons; if there are sound playback and volume control buttons on the steering wheel, use these buttons as much as possible for control; minimize operation of the central control when driving alone. If absolutely necessary, such as when the windshield fogs up, try to slow down, keep your right foot on the brake pedal, and minimize the time your vision is off the road; when visibility through the windows is poor, pull over, complete the operation, and resume driving only when visibility improves.

















I've been driving a GLC, and the location of the infotainment screen's power button isn't always easy to find. Most newer Mercedes models don't have a dedicated physical power button, but you can try these options: The multifunction button area on the right side of the steering wheel has a volume knob - pressing and rotating it can turn the screen on/off; There's a circular touchpad with a return arrow combination button in front of the center console armrest - press and hold the small home icon button in the middle for over 3 seconds; The small square quick-touch buttons above the climate control panel might also hide the shutdown option. The easiest way is to simply use voice command by saying 'Turn off display' and the system will automatically turn off the screen. Actually, for daily use you don't need to manually turn it on/off - it lights up when the vehicle starts and turns off automatically when you shut down the engine, but you can turn it off during long drives if you want to avoid glare.

My husband drives a E-Class and always complains that the screen is too glaring at night. When teaching him how to find the switch, I discovered: in older Mercedes models, there's usually a physical button with a circular arrow icon next to the COMAND knob—just press it to turn off the screen instantly. For newer touchscreen models, simply swipe down from the main menu to find the power icon and tap it to turn off. Holding down the return button in the cruise control area on the left side of the steering wheel can also achieve this. If the car's infotainment system has been modified, the switch might be hidden in the aftermarket module. Actually, the screen turns off automatically when the engine is off, but if you want to save battery while waiting, I personally find voice control the most convenient—just say 'black screen,' and the system responds quite smartly.

My friend just bought a C-Class and noticed how cleverly the screen switch is hidden. Nowadays, Mercedes uses touch controls, and the on/off function is rarely a standalone button. After starting the car, simply swipe up from the bottom of the central control screen to bring up the quick menu, then tap the moon icon to turn off the screen. Holding down the menu button with three horizontal lines in the multifunction area on the left side of the steering wheel achieves the same effect. There's also a hidden key combination in the physical button area below the air vents—press and hold the volume knob and navigation button simultaneously for three seconds. However, Mercedes designers probably think there's no need to frequently turn off the screen, as maps and warning messages need to be displayed at all times. If you really want to shut it down completely, you'll have to turn off the engine; other operations just dim the screen to save power.

During the test drive of the S-Class, I specifically studied the center console switches. The salesperson mentioned that with the introduction of the MBUX system in high-end models, traditional switches have been phased out. There are five common operations: voice command by saying 'Turn off the screen'; swiping down from the top edge of the screen to access the control center and tapping the power button; long-pressing the back button in the touchpad area on the right side of the steering wheel; double-clicking the home button on the air conditioning panel; pressing down the round knob in front of the armrest. The most straightforward method is recommended to be voice operation, which also allows setting an automatic shutdown time, such as turning off the screen when the car is parked for more than 20 minutes.

Last week, I helped my dad set up his old ML350, and it took some time to find the screen power button. The physical button is hidden next to the handwriting pad—a round button with a power symbol. Pressing it turns the screen black. In newer models, there's a 'Display Off' option in the settings menu at the bottom right of the screen. You can also turn it off by pressing the volume roller on the steering wheel. However, Mercedes has a design logic where the screen turns on/off with the engine start-stop, so many people never manually toggle it. It's worth noting that turning off the screen doesn’t affect the rearview camera—it automatically lights up when shifting into reverse, which is a very user-friendly design.
