How to Reset a Mercedes Service Reminder After an Oil Change

How to Reset the Mercedes-Benz Instrument Cluster Service Reminder

This guide shows how to reset the instrument cluster message that says “Service A B Exceeded by XXXXX Miles.”
There are two ways to reset the service reminder interval.

Use the steering wheel buttons to open the instrument cluster service menu. Instructions on how to do that on several different models are shown below.
The second method uses an OBD II scanner that can reset the service intervals on most Mercedes-Benz models. A full system scanner such as the UCAN-II Pro can also scan the other systems in your car, including the airbag system and the engine.

The two most common services are Service A and Service B. For what each one involves, see Mercedes Service A explained and the Mercedes Service B FAQ.

The Service A maintenance appointment will include the following tasks:

Change engine oil and filter,
Check the warning and indicator lamps and horn for functionality,
Check the windshield/headlamp wiper and washer systems for functionality and fluid levels,
Ensure that seat belts are functioning correctly,
Inspect tires and check tire pressure (including spare),
Inspect brake pad thickness and disc condition,
Check and correct all fluid levels, and
Reset your vehicle’s FSS counter.

The Service B maintenance appointment will include the following tasks:

Change engine oil and filter,
Replace windshield wiper inserts,
Inspect all tires for pressure and wear (including spare),
Rotate tires,
Lubricate and inspect throttle linkage,
Check the parking brake for functionality and inspect brake pad thickness and disc conditions,
Check steering play for proper functionality,
Examine headlamps and exterior lamps, warning and indicator lamps, and horn for proper functionality,
Check windshield/headlamp wiper and washer systems for functionality and fluid levels,
Check seat belts and backrest lock (S-Class only) for proper functionality,
Inspect front axle ball joints, rubber boots, and Poly-V-belt,
Check major components for leakage,
Check for chafe marks, line routing, components,
Check and correct all fluid levels, and
Reset your vehicle’s FSS counter.

You will also need to replace the dust filter in all SLK, CLK, C-Class, and E-Class models.

Press buttons repeatedly until the mileage is displayed within the multifunction display.
Press the cluster illumination button (1) 3 times in short succession. The battery voltage will be displayed, and an audible signal will sound. The cluster illumination button is on the left side of the cluster, not on the steering wheel.
Turn the key in the ignition to position “2.”
Press the up/down buttons on the left side of the steering wheel until the service menu appears.
Press the cluster illumination button (1) once. The Oil Type menu is displayed.
Use the buttons to select the oil used for the service.
Press the up or down button to confirm. The display will show: “Reset Oil Confirmation. Push R-Button for 3 seconds”.
Press and hold the cluster illumination button (1) for 3 seconds. The message “Service confirmed” is displayed.

Within 4 seconds, press the “0” button twice. The present status for days or distance displays, and within 10 seconds, turn the electronic key in the steering lock to position 0.
Press and hold the “0” button while turning the electronic key in the steering lock to position two again.
The present status for days or distance displays once more.
Hold the “0” button for approximately 10 seconds until a signal sounds, and the display shows 10,000 mi (15,000 km) for approximately 10 seconds. Release the “0” buttons; the status is reset.

W210 E-Class, 2001 to 2002

Turn the key in the steering lock to position 2.
To call up the trip and main odometer, press either of the lower two buttons on the left-hand side of the steering wheel (system select looks like a file folder) until the display appears.
Press either of the top buttons on the steering wheel (arrows) until the FSS indicator appears.
Press the R button on the instrument cluster for 2 to 4 seconds.
The display reads DO YOU WANT TO RESET SERVICE INTERVAL? CONFIRM BY PRESSING R. Press the R button on the instrument cluster again and hold until the signal sounds.
The message SERVICE INTERVAL HAS BEEN RESET appears on the multifunction display.

When the Menu Reset Does Not Work

On later models the menu sequence changes with each cluster generation, and some cars will not take a reset through the buttons at all. If the procedure above does not work on your car, use the UCAN-II Pro to reset the service reminder through the instrument cluster or the maintenance system from the OBD port. Other models have their own guides: SLK R170 oil service reset and Sprinter service reminder reset.
