What is the method to reset the maintenance light on a Mercedes-Benz E260L?

Power on the car while keeping the engine off; press the reset button once, and the display will show the reset system. Each press of the reset button will switch to the next reset system; select the maintenance reset system and hold the reset button for about 3 seconds.

Last time I reset the maintenance light for my Mercedes-Benz E260L, it was quite simple. Turn off the car, rotate the key to the ON position (dashboard lights up but don't start the engine). Use the control button on the left side of the steering wheel to scroll through the menu and find the 'Maintenance' or 'Service' option, then select it. The screen will display remaining mileage and time information—follow the prompts to choose the reset function, then hold the OK button for a few seconds until the light turns off or you see a confirmation message. The whole process takes less than a minute, and I saved money by doing it myself instead of going to the dealership. Remember to do this immediately after maintenance to avoid misleading the system with false alerts for the next reminder. If the maintenance light stays on before a long trip, it could affect safety judgment. I do this after every service—it's hassle-free and helps maintain regular upkeep habits.
