Screen luminance control and cabin glare reduction on the 2023 Mercedes S-Class are managed by ambient light sensors, MBUX brightness sliders, and automatic day/night display modes.
How to Fix It:
-
Open System Settings: Tap the settings icon on the central OLED touchscreen and select the "System" or "Display" menu.
-
Adjust Brightness Level: Use the on-screen slider to manually increase or decrease screen illumination to match your lighting preference.
-
Enable Auto Mode: Leave the brightness set to automatic so the vehicle's ambient light sensors dynamically adjust screen glare between daytime and nighttime driving conditions.
