Mercedes has no service required at 100,000 miles.
Do you have the maintenance booklet? If not, I recommend buying one at the dealer.
Just know that all the maintenance on MB's is carried out in mileage, except for two items, which are carried out in time:
1. Brake Fluid - Flush and refill brake fluid every two years.
2. Radiator Fluid - Flush and refill radiator fluid every three years. Also MB fluid is a yellow-ish color, not green. It has a different chemical make-up than regular green "prestone-style" fluid, which you shouldn't use. It is only slightly more expensive that regular fluid anyway.
