Additional Notes
- The GMC Acadia C1XX-2 brake fluid fill level for both the 2.5 and 2.5 AWD configurations starting in 2024 is specified as between the minimum and maximum marks on the reservoir, rather than as a fixed volume. A between-min-and-max specification is standard for brake fluid reservoirs, where the level naturally fluctuates as brake pads wear and the caliper pistons extend further.
- The 60-month change interval applies under normal use conditions for both the front-wheel-drive 2.5 and the AWD 2.5 variants. A 60-month interval is on the longer end of typical brake fluid service schedules, reflecting a moisture absorption threshold rather than a mileage-based wear criterion.
- Brake fluid is hygroscopic, meaning it absorbs moisture from the atmosphere over time. The 60-month normal-use interval for the 2024 Acadia 2.5 and 2.5 AWD is tied to this property, as accumulated moisture lowers the fluid's boiling point and can lead to vapor lock under heavy braking.
- The hydraulic brake system note applies identically to both the 2.5 and 2.5 AWD configurations, indicating no differentiation in brake fluid service requirements between the two drivetrain variants for the 2024 model year.
