What is the "C" service?

The manual only mentions the A and B but when I check the on board computer it says C service in XXXXX miles.

I ask the salesman but he doesn't know.

Any ideas?

Actually, the owner's manual (p. 371) says the service indications range from A (about 1 hour labor) to H (about 8 hours).

However, the Maintenance Booklet (p. 49 - 63) contains complete service listings. The services are numbered 1 - 20, although #6, 7, 9, 10 & 14 - 19 are listed as "not applicable." This is a summary (the manual has more detail) --

Once at 1,000 - 3,000 miles:
First visit - Diagnostic test

First at 13k / 1 year , then every 26k / 2 years:
Service 1 - General check
Service 3 - Replace oil & filter

First at 26k / 2 years, then every 26k / 2 years:
Service 2 - General check
Service 3 - Oil & filter change
Service 4 - Body check & replace brake fluid
Service 5 - Replace HVAC filter

Every 52k / 4 years:
Service 8 - Replace engine air filter

Every 65k / 5 years:
Service 11 - Replace fuel filter

Every 91k (V6) or 78k (V8) / 5 years:
Service 12 - Replace spark plugs

Every 143k / 15 years:
Service 13 - Replace coolant
Additional high-mileage checks

Once at 39k:
Service 20 - Replace transmission fluid

So, I guess C will be three hours. I still have a few more months.

How does this list convert to service B ?

I am currently at around 38k, and indicator says Service B due soon,
so I think it's either Service 1 or 3 ? Any idea what Service B includes ?

Thx!
