When you follow the reset procedure, make sure you turn the key all the way to the on (run) position, not just the accessory power position. It's easy to just turn it to that first stopping point, but that will not reset the FSS.

1. Turn key to the ON/RUN position.
2. Within one second press the ****/button twice.
3. The present status for days or distance is displayed.
Within 10 seconds turn the key to OFF/
LOCK.
4. Press and hold the ****/button, while turning
the key to ON/RUN again. The present status for
days or distance is displayed once more. Continue
to hold the ****/button.
After approximately 10 seconds, a signal sounds and
the display shows 7,000 miles (Canada: 11,000 km) for
approximately 10 seconds.
5. Release the ****/button.
