Steps to Reset a Mercedes-Benz Check Engine Light
If everything checks out and you still want to reset the light, follow these steps:
- Turn the Key (But Don’t Start the Engine)
Insert your key into the ignition and turn it to the “On” position without starting the engine. Check the display between your speedometer and tachometer. - Access the Diagnostic Display
On the left side of the steering wheel, locate the four control buttons. Press the lower left button to navigate the display. This should show the reason behind the check engine light—often a routine service reminder. - Scroll Through the Information
Press the lower left button again to view your vehicle’s mileage. Then, press the lower right button to display the reason for the warning light again. - Find the Reset Button
Locate the reset button on the left side of the instrument cluster. Press and hold it until the screen reads:
“To reset: Press reset button for 3 seconds.” - Complete the Reset
Press and hold the reset button once more for three seconds. The system should confirm the reset and display your next scheduled service based on mileage.
