There is a seperate maintenance booklet that came with the car. This is a pamphlet for keeping track of all service and details every procedure that is carried out at each maintenance interval. This is why none of it is detailed in the owner's manual. They produced a seperate manual for maintenance which from the looks of it, you did not get from the previous owner when you puchased the vehicle. You can probably obtain one from the dealer or by calling 1-800-FOR-MERC.

Oil change interval is every 7,500 miles. Personally, I change my oil twice as often, every 3,750 miles.
