Additional Notes
- The rear electric drive differential fluid capacity across all listed Lexus UX (EU) configurations is 1.2 liters, which is consistent with a service fill volume rather than a full overhaul drain-and-refill of a larger conventional differential assembly.
- Under normal use conditions, the UX 250h (2019-2020) rear electric drive differential specifies only a fluid check at 45,000 km or 36 months, with no fluid change interval listed for that use condition.
- Under severe use conditions, the UX 250h (2019-2020) rear electric drive differential carries both a check interval of 45,000 km or 36 months and a change interval of 90,000 km or 72 months, meaning severe operation introduces a mandatory fluid replacement that normal use does not.
- The same check and change intervals that apply to the UX 250h (2019-2020) under both normal and severe use are also specified identically for the UX 250h AWD (2019-2020), indicating no interval differentiation between the non-AWD and AWD variants for the rear electric drive differential.
- The UX 250h AWD variant carrying the MZAH15 engine code, with a starting year of 2020, shares the same 1.2-liter capacity and the same 45,000 km or 36-month check interval under normal use as the earlier AWD configuration.
- For the MZAH15-coded UX 250h AWD under severe use, the fluid change interval remains at 90,000 km or 72 months, matching the severe-use specification of the non-engine-coded AWD entries from 2019-2020.
