Additional Notes
- Both the Astra L HYBRID configurations, the 133 kW DGX and the 165 kW DGY, share the same brake fluid specification approach: the reservoir level is maintained between the minimum and maximum marks rather than a fixed fill volume being stated.
- A "between min and max" specification is typical for brake fluid reservoir top-up guidance, meaning no discrete capacity figure in liters is assigned, as the system is serviced by visual level inspection rather than a measured quantity.
- The hydraulic brake system note present in both rows indicates that, despite the hybrid drivetrain, conventional hydraulic actuation is retained for the braking circuit, which is why a standard reservoir-level specification applies.
- The 133 kW DGX and 165 kW DGY variants carry identical brake fluid service specifications under normal use conditions, meaning the difference in power output between the two hybrid configurations does not produce a variation in brake fluid capacity or fill guidance.
