How to Reset the Maintenance Reminder Light on a Mercedes-Benz?

[LeWyatt]

Switch the dashboard to the odometer interface, press the phone button on the right side of the steering wheel, then immediately press the OK button on the left side of the steering wheel, and follow the prompts to press the corresponding buttons. Hold down both the OK and phone buttons on the steering wheel simultaneously, use the up and down buttons to switch to the maintenance line, select the appropriate option with the directional buttons, and press OK to confirm. Then select the bottom row in English, press the OK button, choose the full set of maintenance, and then select confirm. Once the reset is complete, turn off the key and wait for 30 seconds before turning it back on. You will see that the maintenance reminder light has been reset in the dashboard.

I just bought a Mercedes-Benz C-Class last year, and the first time that maintenance reminder light came on, it gave me quite a scare. Here's how to reset it: After getting in the car, don't start the engine—just turn the key to the accessory position to power up the dashboard. Use the buttons on the right side of the steering wheel to navigate—press and scroll left or right to find the 'Settings' menu, then go into 'Vehicle Data' or a similar option, select 'Service,' and there should be a reset button. Just confirm, and you're done. My car is a 2022 model, and this whole process took less than two minutes. But be careful not to mess it up—different Mercedes models have different reset procedures. For example, the S-Class might require a few extra menu presses. My friend's older E-Class actually needed him to hold down both the OK button and the phone button for a few seconds before powering on. Once reset, the light turns off immediately, which is a huge relief. That light is actually a friendly reminder that it's time for an oil change or inspection—ignoring it for too long could affect your warranty or increase the risk of issues, so don't procrastinate. Regular maintenance is key—I go to the dealership every six months, and along the way, I picked up this little trick, which saves both money and hassle.

I've been driving a Mercedes for over a decade and have dealt with this maintenance light several times. Simply put: Sit in the car with the key turned to the ignition-on position (don't start the engine). There's a control wheel button on the steering wheel - use it to navigate the instrument cluster menu, find the wrench icon, enter and select 'Reset Service Indicator' then confirm. My GLC model does it with one click, but procedures vary across model years. Post-2020 Mercedes may require accessing the vehicle settings menu for reset. Best to check your owner's manual for that specific section. Avoid random button presses to prevent system errors. The light disappearing confirms you've addressed the maintenance - maintaining this habit extends vehicle lifespan. I've seen cases where neglect led to engine knocking, costing thousands in repairs. After resetting, drive a short distance and recheck the light to confirm success for added assurance.

I remember when I first got the keys to my Mercedes last year, the maintenance light came on and I didn't know what to do. Here's how I handled it: After turning off the engine, rotate the key to the second position to power on the electronics without starting the car. Use the steering wheel buttons to navigate the dashboard menu to the settings, select the maintenance item, and confirm the reset. That's how I fixed it on my old A-Class. Newbies should be careful; if the light doesn't go off after resetting, it might mean the reset wasn't successful or professional diagnosis is needed—don't force it, just drive to the 4S shop and ask a technician. This light is a reminder for basic maintenance like oil and filter changes; neglecting timely service can lead to increased fuel consumption and faster tire wear over time. Always take a quick glance at the dashboard before driving to prevent issues.
