How to Reset the Maintenance Light on a Mercedes Benz C300

by 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.

Step 1

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.

Step 2

Press the "menu" button on your instrument panel, until the current mileage appears on the display.

Step 3

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.
