Additional Notes

  • Transfer case fluid capacity across all W203/S203/CL203 4MATIC variants holds at 0.59 liter, a figure consistent with the compact transfer box units found in passenger car-based all-wheel-drive systems rather than the larger units used in dedicated off-road platforms.
  • Every row carries a "first change only" designation, meaning the specified interval applies solely to the initial fluid drain and refill after the vehicle enters service, not to a recurring maintenance schedule.
  • The Mercedes-Benz C 240 4MATIC (203.081/281) and C 320 4MATIC (203.084/284), both covering model years 2000-2005 and 2000-2004 respectively, share a first-change interval of 39,000 miles.
  • The C 280 4MATIC and C 350 4MATIC variants from 2005-2007 carry a slightly higher first-change interval of 40,000 miles, a 1,000-mile increase over the earlier 39,000-mile figure seen on the C 240 and C 320.
  • The 0.59-liter capacity is a service fill figure, representing the amount of fluid needed during a standard drain-and-refill procedure rather than a complete overhaul or dry-fill quantity, which would typically be higher.
  • The C 280 4MATIC and C 350 4MATIC each appear under two separate year entries both spanning 2007, with identical capacity and interval values of 0.59 liter and 40,000 miles across all entries.
