| Type | Specifications |
|---|---|

Additional Notes
- The 1.2 PureTech 130 with HNS gearbox (2018-2022) covers only the hydraulic brake system, while the same engine paired with the HNY gearbox (2015-2019) covers a combined hydraulic brake and clutch system, reflecting a fundamental difference in how fluid is shared across systems depending on transmission type.
- Both configurations specify a fill level between the minimum and maximum reservoir marks rather than a fixed volume, which is characteristic of a top-up or inspection service rather than a full system overhaul requiring a measured quantity.
- The Citroën C4 Cactus 1.2 PureTech 130 with HNY gearbox shares brake fluid between the brake and clutch circuits, meaning a single reservoir services both hydraulic functions simultaneously.
- Both rows carry a normal use condition, meaning the stated fill specification applies under standard operating circumstances rather than a severe or first-change-only scenario.
