Hold the O button for a couple of seconds to reset the trip odometer.

The R button is the Multi-function Reset button. If you get an error message (Lamp Defective, etc) you can clear it to return to a normal display but it will return the next time the key is turned on.

Oil level check - Turn the key to position #2 and wait. When the 'Check oil level message appears' press O button twice quickly. If the car has been running you will get a message to wait. Wait 5 min for the oil to drain back into the pan.

There's enough electronics on the W210 that a manual is almost a must. The best place to get a manual is at the dealer. They are cheaper than eBay and you'll end up with the correct one for your model.
