Additional Notes
- The brake fluid capacity for the Mercedes-Benz GLC-Class / Coupé X254 / C254 is expressed as a fill range rather than a fixed volume, with the reservoir to be maintained between the minimum and maximum marks on the reservoir.
- A 24-month change interval applies to the GLC 300 (254.146/346/646) under normal use conditions, meaning the fluid is replaced on a calendar basis regardless of mileage accumulated within that period.
- The GLC 300 4MATIC (254.147/347/647) carries the same 24-month change interval under normal use, with the fill level likewise governed by the min-to-max reservoir range.
- The GLC 43 AMG 4MATIC (254.187/387/687), introduced for the 2023 model year, shares the identical 24-month brake fluid change interval and min-to-max fill specification as the GLC 300 variants, despite the AMG model's higher-performance braking demands.
- All three configurations specify the hydraulic system as a combined brake and clutch circuit, indicating the brake fluid reservoir serves both functions within a shared hydraulic architecture.
- The 24-month interval is tied specifically to normal use conditions across all listed variants, which in Mercedes-Benz service terminology refers to standard on-road driving as opposed to track or severe-duty operation.
