Back to the owner's manual. I haven't had the need to try this and from what I read on this forum,
the FSS reset may not be as simple as this appears.
Section 4 page 107...

The counter can also be reset by any individual after the
indicated service has been performed. To do so:

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.
If the FSS counter was inadvertently reset, have an
authorized dealer correct it.

The message is displayed for approximately 10 seconds
when turning the key to the ON/RUN position,
or while driving when reaching the service warning
threshold. It can be canceled manually by pressing the
****/button.

Once the suggested term has passed, the message plus
either the symbol for Service A or the symbol for
Service B preceded by a – (minus symbol) blinks for
approximately 30 seconds and a signal sounds every
time when turning the key to the ON/RUN position.

The FSS display can also be called up for approximately
10 seconds with the display illuminated by
pressing the ****/button twice within one second.
