Mercedes-Benz E-Class: How to Reset Your Service Indicator
Often times, the service indicator will stay on after you've changed the oil in your E-Class w212. This article provides the steps to reset the indicator yourself.
This article applies to the Mercedes-Benz E-Class w212 (2009-Present).
The service indicator in your w212 always comes on to remind you of an upcoming oil change. While this is a great maintenance feature, it can also be frustrating if the light stays on after your oil has been changed. Instead of taking the car to the dealership, which can be quite costly, the following steps will help you reset the light on your own.
Step 1 – Turn ignition to position "1"
Make sure all the doors are closed, then press the ignition button once to place it in position "1."
Step 2 – Scroll to the "Trip" option
Press the left or right system selection button until the menu choice "Trip" is highlighted in the multi-function display.
Step 3 – "Accept" a phone call
Hold the "Accept Phone Call" button located on the right side of the steering wheel. While holding the button down and within five seconds, press and hold the "OK" button on the left side of the steering wheel.
Step 4 – Press the scroll forward button
Repeatedly press the scroll forward button until "ASSYST PLUS" is highlighted and stored, then confirm selection by pressing the "OK" button.
Step 5 – Restore to "Full Service"
Press the scroll forward button until "Full Service" is highlighted. Confirm the selection by pressing the "OK" button.
Step 6 – Reset the service indicator
Press the scroll forward button until "Conf. Full Serv." is highlighted. Confirm the selection, and reset the service indicator by pressing the "OK" button. Once the service indicator is reset, place the ignition back to position "0."
