I have an 2003 ML500 that displays the negative(-) mileage to oil change message.

I change the oil myself and I can't find my manual so I don't know how to reset this.

Any advice would be much appreciated! THANK YOU!

Resetting FSS + Cabin Air in 04 ML350

Here are the steps that I got from the link you've given me, but what/where can I locate button 1:
----------------------------

1. Turn key to position 2.

2. Within 4 seconds press button 1 twice.

3. The present status for days or distance is displayed. Within 10 seconds turn key in steering lock to position 0.

4. Press and hold button 1, while turning key in steering lock to position 2 again. The present status for days or distance is displayed once more. Continue to hold button 1. After aproxtamely10 seconds a signal sounds, and the display shows 10,000 miles for approximately 10 seconds.

5. Release button 1.

After numerous attempts and frustration, am I required to purchase the FSS reset key?

1) shut door, wait until the dome lamp goes off.

2)button #1 is the trip reset button.
