Oil change , rotate tires (if needed) , engine air filter , cabin air filter , Automatic trans. fluid (drain & fill only- Honda fluid only), Brake fluid flush.Inspection of drivetrain. The dealership I'm at , we don't usually do coolant (drain & fill only) until 45K. Don't be surprised if your rear brake pads are getting low - they wear a lot faster than the fronts on those.
It depends on the vehicle,but for the most part a coolant flush,trans service,rotate tires,inspect brakes,fuel filter,air filter,top all fluids,and an overall vehicle inspection.
