Hello, I am a new member. I own a 2016 prius 2. It is a great car. I now have 60k miles on it and the service manager at the dealership says I should have the coolant changed, the trans diff fluid changed, the hybrid motor inverter fluid changed and the throttle body induction serviced, all to the tune of about $500. I looked in the owners manual under scheduled maintenance and it states for schedules refer to the "Scheduled maintenance Guide" or "owners manual supplement" neither of which I have. Am I missing something? Shouldn't the maintenance schedule be in the owners manual? Are these actions really necessary at this time?
