After I change oil + filter how do I reset the FSS warning which apears in the dashboard? This is for a 1999 E300 TD.
Thank you in advance!!!

FSS reset procedure
 

It should be in your owner's manual. On my 1998 E 430 the process is clearly explained on page-93.

Make sure your doors are closed.

1) Insert key into ignition and turn to position 2.

2) Within 4 seconds push button "0" and release.(this is the odometer reset button)

3) Within 10 seconds turn key to position 0.

4) Press and hold button "0" while turning the key back to position 2. Continue to hold button "0".

5) After approx 10 seconds a signal sounds and the display will show 10000 miles or 15000 km. Release the button.

This is correct, except step 2, you have to push the 0 button twice within 4 seconds or so to get the FSS to display......Gilly
