Additional Notes
- The Citroën C4 X brake fluid specification applies to the hydraulic brake/clutch system, meaning a single shared fluid reservoir serves both the braking and clutch hydraulic circuits in these configurations.
- Both the 1.2 PureTech 100 (HNE) and the 1.2 PureTech 130 (HNS) variants share the same fill guidance, with the correct fluid level sitting between the minimum and maximum marks on the reservoir.
- The specifications are listed under normal use conditions for both engine variants, which in fluid servicing contexts refers to standard operating environments as opposed to more demanding or severe duty cycles.
- No numeric capacity figure is given for either variant, as brake fluid reservoir servicing is governed by the min-to-max range rather than a fixed volume fill.
