Honda uses a maintenance minder system that determine what services are required, and when they need to occur. You should have some info in the dash, like an "A" or "B" followed by the number 1-6 Do you have any of these on in the dash?
Thanks for the info, but I am referring to a Ridgeline, I do understand the dash indicator display. It's the same or nearly for service intervals. What I really want to know is what is the service required at 40,000 miles. Exactly what is inspected and serviced at 40k.
