Mercedes-Benz oil life light reset
To reset the oil life light on a Mercedes-Benz (Non-COMAND/older models with an R (reset) button): Turn the key to position 2 (ignition on, engine off). Press and release the R button on the instrument cluster to cycle to the relevant service-due display. Turn the ignition off, then press and hold the same R button while turning back to position 2 until the service light resets.
Key takeaways
- Change the oil first - the light is only a reminder.
- 2 procedures listed for Mercedes-Benz, by model year or family.
- No special tool needed for the procedures below.
- If it does not work, confirm your exact year in the owner's manual.

COMAND/steering-wheel-menu models (roughly 2015+)
- Turn the ignition on without starting the engine.
- Use the steering-wheel controls to navigate the instrument cluster to the Service or Assyst Plus menu.
- Select Reset (or the specific A/B service item) and confirm.
Many current Mercedes models (Assyst Plus with COMAND/MBUX) will not let the owner fully clear the counter and require a dealer or independent shop with STAR diagnostics; the on-screen reset only works for a subset of models/services.
