Thanks to people who have posted this procedure earlier.

FSS Reset

1. turn the key to the on/run position.
2. within 1 second press the **** to the left of the display twice.
3. present status for days remaining or distance traveled is displayed. within 10 seconds turn key to off.
4. press and hold **** on left side of display while turning key to on/run again. present status is displayed once more. continue to hold button. after approx. 10 seconds a tone sounds and the display shows 6,000 miles for approx. 10 seconds.
5. release the ****

You should be able to do this. It takes a few attempts to get it right. One pointer ...the 10 seconds in step 3 refers to 10 seconds after the key is turned to the ON position. You have to turn it off before that expires. Let me know how it turned out.
