How do I care for and clean the seat cover, and can the cup holders go in the dishwasher?

Cup holders are removable and are top rack dishwasher safe. To remove them, tilt the cup holder slightly forward at the base and pull up to release from the seat (remove the screw first if one was used for Canadian models). Instructions for removing and reattaching the seat cover are covered on pages 70–75 of the manual. (Page 22)
