Additional Notes
- The Hyundai Bayon BC3 (EU) automatic transmission fluid specifications cover a semi-automatic transaxle unit across all listed 1.0 T-GDI configurations, including standard, 74 kW 48V-Hybrid, and 88 kW 48V-Hybrid variants.
- A semi-automatic transaxle combines elements of manual and automatic transmission design, and the 1.6-1.7 liter capacity range listed across all configurations reflects a service fill volume rather than a full overhaul or dry fill, which would typically be higher.
- Under normal use conditions, the service interval for the semi-automatic transaxle is a fluid check at 48 months or 60,000 km, with no fluid change interval specified for normal use across any of the listed variants.
- Under severe use conditions, the same 1.6-1.7 liter capacity applies, but the service schedule adds a mandatory fluid change at 120,000 km alongside the check interval of 60,000 km or 48 months.
- The severe use change interval of 120,000 km applies identically to the standard 1.0 T-GDI, the 74 kW 48V-Hybrid, and the 88 kW 48V-Hybrid, indicating no differentiation in fluid change frequency between the mild-hybrid and non-hybrid drivetrains under demanding operating conditions.
- The 74 kW and 88 kW 48V-Hybrid variants share the same 1.6-1.7 liter transaxle fluid capacity, meaning the addition of the 48V mild-hybrid system does not alter the transmission fluid volume requirement relative to the standard engine variant.
- The capacity is expressed as a range of 1.6-1.7 liters rather than a fixed value, which is common for semi-automatic transaxles where the precise fill level is confirmed by a level check procedure rather than a fixed pour quantity.
