I've been driving a Mercedes-Benz E300 for several years, and the maintenance reset requires careful attention. First, sit in the car without starting the engine, just turn the ignition to the second position where the dashboard lights up. Then, press the return button on the left side of the steering wheel with your left hand, while simultaneously pressing the phone hang-up button and the OK button with your right hand. Wait a few seconds for the menu to appear. Locate the maintenance option, select confirm reset, and you're done once it shows success. Remember, the menu for the 2018 E300 might be hidden in the vehicle settings. If you can't find it, check the owner's manual for detailed diagrams on the relevant page. Doing it yourself saves a few hundred bucks from the dealership visit, but be careful not to press other settings randomly, as it might mess up the mileage or tire pressure data. Regular resets ensure the system accurately reminds you of the next maintenance schedule, protecting the engine's lifespan. I check it monthly, and the car runs smoother.
Last time I reset the maintenance reminder for my 2018 E300, and the process was actually quite simple. You sit in the driver's seat, turn the key to the ON position without starting the engine, press and hold the multifunction button on the left side of the steering wheel for about three seconds, and the instrument cluster will display the menu. Use the directional buttons to scroll to the maintenance information, select it, and then choose reset confirmation. The whole process takes less than a minute, but make sure the car is parked with the handbrake engaged. The first time I tried, I forgot to turn off the engine, so the menu didn't appear, which wasted some time. After resetting, the system automatically calculates the next maintenance mileage, saving you from having to remember the date. I recommend doing it immediately after each maintenance to avoid missing reminders. Mercedes-Benz's design is quite user-friendly—doing it yourself saves worry and money, and you also get to understand the details of your car's condition.
