How to Adjust the Brightness of the Mercedes-Benz GLC Infotainment Screen?
2 Answers
Hold down the adjustment button on the instrument panel, and the LCD screen will respond. When the LCD screen displays TRIPB, release the adjustment button. Turn on the small light or headlight switch of the combination switch. At this point, hold down the adjustment button without releasing it, and the backlight brightness will start to adjust. It can be adjusted among three states: brightest, normal, and darkest. Release the button once the desired brightness is achieved. After adjustment, press the adjustment button again to switch the odometer display from TRIPB to ODO.
When I first started driving the Mercedes GLC, I also explored this issue. From the bottom of the main screen, find the little house icon and tap into it, then swipe to the settings option and select the display menu. There you'll find the brightness adjustment slider. I recommend turning on the automatic mode, so when entering or exiting tunnels or driving at dusk, the screen will automatically brighten or dim, which is much more convenient than manual adjustment. If you have applied a dark window film, the automatic sensor might not be as accurate, so it's advisable to manually adjust to around 70% during the day. At night, the system will link with the headlights to switch to night mode, with brightness defaulting to a lower level to avoid glare from reflections. There's no need to specifically save the settings after each adjustment—they take effect automatically upon exiting. The key is to experiment several times under different lighting conditions to find the brightness level that feels most comfortable for your eyes.
