Additional Notes

  • The transfer case fluid capacity for the Mercedes-Benz SL-Class R232 (EU) is expressed as a range of 0.65-0.68 liter across the SL 55 AMG 4MATIC+ (232.480) and SL 63 AMG 4MATIC+ (232.481), reflecting the typical variation seen in service fills where the final accepted level falls within a tolerance band rather than at a single fixed volume.
  • The SL 63 AMG S E Performance 4MATIC+ (232.482) carries a fixed capacity of 0.68 liter with no lower bound, meaning the fill target is a single precise value rather than a range.
  • All three configurations share an identical service interval of 80,000 km or 36 months under normal use conditions, whichever comes first, placing the time-based limit at three years regardless of mileage accumulation.
  • The 80,000 km distance interval is consistent across the SL 55 AMG 4MATIC+ (232.480), SL 63 AMG 4MATIC+ (232.481), and SL 63 AMG S E Performance 4MATIC+ (232.482), indicating no differentiation in transfer case service frequency between the standard AMG variants and the hybrid performance variant.
  • All three configurations are designated for normal use conditions, meaning the stated intervals apply to standard operating environments rather than severe-duty cycles such as frequent towing, extreme temperatures, or off-road use.
  • The transfer case unit is identified as a transferbox across all three configurations, which in the context of an all-wheel-drive system refers to the mechanical unit responsible for distributing torque between the front and rear axles.
