The first service would normally be an oil service only.
This should be accomplished (per the owners manual) either based on the
lights (mileage) or annually, whichever comes first. At the time that a
"time based" oil service occurs the service indicator should be reset and
you start both clocks over again (mileage lights and time).

Check to see if they accomplished all of the items on the oil service
checklist. They may not have. The clock icon indicates a bi-annual service
is due. That is the one where they just flush the cooling system and brake
lines. If you have not changed your oil in 2 years you are due (or
overdue). Just have them perform the oil service and you will be back in
sync now.
