Additional Notes
- The CLS 450 (257.358) and CLS 53 AMG 4MATIC+ (257.361) both carry a brake fluid capacity of 0.5 liter for the hydraulic brake system, representing the total reservoir volume used during a normal service fill.
- The Mercedes-Benz CLS 450 4MATIC (257.359) does not specify a fixed volume figure, instead referencing a fill level between the minimum and maximum marks on the reservoir, which is a level-check approach rather than a measured quantity fill.
- All three configurations apply their brake fluid specifications under normal use conditions, meaning the intervals and fill levels listed are not adjusted for severe driving cycles or extended service programs.
- The CLS 450 4MATIC (257.359) covers model years 2018-2023, while the CLS 450 (257.358) and CLS 53 AMG 4MATIC+ (257.361) are each listed for 2018-2022, representing a difference in the span of years covered across the three variants.
- A 0.5 liter brake fluid capacity is a relatively modest reservoir volume, consistent with passenger car hydraulic brake systems where the reservoir primarily compensates for fluid displacement as brake pads wear rather than storing large working volumes.
