1) Turn key to position 1
2) With the display in the "default" normal driving position, (this should be speed or temperature) press the reset button three times.
3) The display will now read the battery voltage
4) Press down arrow once to get to service menu
5) Press "-" (minus) three times until you highlight "confirmation"
6) Page Down (key next to arrow down) to advance to the next menu
7) You should see Confirm Full, Cancel Full, Cancel Items.
8) Turn ignition key to position 2 (I think you could do this anytime after step 4 above)
9) Press Page Down while Confirm Full Service is highlighted
10) You should get a message confirming success
11) Repeat Page Up (key next to up arrow) until you reach the standard display
12) Start the engine
13) Page up to the screen that normally says Service "X" in "NNNN" miles. It should read "Reading Data Please Wait".
14) After 30 seconds or so it will read "Service "X" in 13000 miles.

You can also get to the service menu by holding the reset button down while the "Service "X" in "NNNN" miles" is displayed. But this seems to be a reduced function menu.

If you decide to change the date of the next "General Inspection" make sure you choose a date in the future. I thought the years and month were relative to the current date. So when I set the counter to year:0 and month:6 it thought I meant either 2000 or 1900 since it reported that I was 16020 days (43 years) past due for the inspection. I reset the date to year:5 month 10 (October,2005) and it is now happy with no error messages. It should start complaining in November.

I am happy to report that TeleAid did not call me to tell me that someone was tampering with the FSS reset menu. []This works on a 2006 SLK 280, but you have to press the reset button 3 times really fast while the airbag warning light is still on. After that just follow the above directions. The key presses are counter-intuitive since they don't work like the other menus but it does reset the FSS indicator.
