Additional Notes

  • All three Hyundai IONIQ 6 CE EV (EU) configurations share an identical brake fluid service interval of 30,000 km or 24 months, whichever comes first, under normal use conditions.
  • The 24-month time limit means the fluid is due for replacement after two years regardless of whether the distance threshold has been reached, reflecting the hygroscopic nature of brake fluid, which absorbs moisture over time and lowers its boiling point.
  • Across the 53 kWh RWD, 77 kWh RWD, and 77 kWh AWD variants, the specified fill level is between the reservoir minimum and maximum marks rather than a fixed volume, which is the standard approach for hydraulic brake system top-ups during routine service.
  • The AWD configuration, producing 239 kW across two motors, follows the same 30,000 km / 24-month brake fluid interval as the single-motor RWD variants, despite the added complexity of a front axle motor unit.
  • The 77 kWh battery is paired with two distinct power outputs, 168 kW in the RWD variant and 239 kW in the AWD variant, yet both share the same brake fluid service schedule as the lower-capacity 53 kWh model.
  • All three configurations are noted specifically as hydraulic brake systems, which is relevant for an electric vehicle platform where regenerative braking handles a significant portion of deceleration, yet a conventional hydraulic circuit remains present and requires periodic fluid maintenance.
