Additional Notes

  • The Mercedes-Benz SLR McLaren C199 / R199 rear differential carries two listed capacity values rather than one, with 1.8 liters and 2.2 liters both appearing under a flexible (max) use condition for each configuration.
  • A flexible (max) use condition means the interval or fill quantity represents the upper boundary within a variable servicing schedule, rather than a fixed mandatory point.
  • The coupe variant, chassis code 199.376, spans two separate year groupings in the specifications: 2003-2007 and 2007-2009, each carrying the same dual capacity figures of 1.8 and 2.2 liters for the rear differential.
  • The Roadster variant, chassis code 199.476, covers the 2007-2009 period and mirrors the coupe's rear differential capacity range exactly, with the same 1.8-liter and 2.2-liter values listed under the flexible (max) condition.
  • The presence of both a lower figure of 1.8 liters and a higher figure of 2.2 liters for the same rear differential suggests a distinction between a standard service refill quantity and a full overhaul or drain-and-fill capacity.
  • Across all six specification rows covering both the coupe and Roadster body styles, the use condition remains consistently listed as flexible (max), indicating no configuration in the data carries a fixed or severe-duty interval designation for the rear differential.
