Additional Notes

  • All three R172 configurations — the SLK 250, SLK 350, and SLK 55 AMG — share an identical brake fluid capacity of 0.5 liter for the hydraulic brake system.
  • A 0.5 liter capacity figure for a brake fluid reservoir is consistent with a service fill volume, representing the amount needed to replenish or replace fluid in the system rather than a full hydraulic overhaul quantity.
  • The Mercedes-Benz SLK-Class R172 specifies a 24-month change interval for brake fluid across all listed configurations, applied under normal use conditions.
  • The 24-month interval is a time-based service schedule, meaning the change is due after two years regardless of mileage accumulated during that period.
  • The SLK 55 AMG, chassis code 172.475, carries the same 0.5 liter capacity and 24-month interval as the lower-displacement SLK 250 and SLK 350, indicating no differentiation in brake fluid service specs between the AMG variant and the standard models.
  • The SLK 55 AMG coverage begins in 2012, while the SLK 250 and SLK 350 coverage begins in 2011, reflecting a one-year offset in the AMG model's introduction within the R172 generation.
