How to Reset the Maintenance Light on a Mercedes Benz C300by Tara Kimball
The Mercedes C300 Series includes a monitoring system that triggers an alert when your car is due for an oil change or other service. Service technicians at a Mercedes dealership typically clear the alert and reset the service. Resetting the service and clearing the alert at home requires just a few minutes.
Sit in the driver's seat of the car, and place the key in the ignition. Turn the key until it reaches the first position.
Press the "menu" button on your instrument panel, until the current mileage appears on the display.
Press and hold the "Reset" button on the instrument panel for three seconds. Press "Reset" again to confirm when the service-interval-reset prompt appears.
Turn the key to "OFF," and remove it from the ignition.
