Additional Notes
- The Lexus UX 250h AWD carries a rear electric drive differential fluid capacity of 1.2 liters across all listed configurations for both the USA and Canadian markets.
- A capacity figure of 1.2 liters is consistent with a service fill specification, reflecting the amount of fluid required during a routine fluid check or top-up rather than a full overhaul drain-and-fill procedure.
- The rear differential in the UX 250h AWD is associated with the electric drive unit, which is the mechanism delivering power to the rear axle in the hybrid all-wheel-drive system without a mechanical connection to the front-mounted engine.
- Canadian market specifications list the rear electric drive differential fluid check interval at 48,000 km or 36 months under normal use conditions, applying to the 2019-2021 configuration.
- USA market specifications list the same service interval as 30,000 miles or 36 months under normal use conditions for the 2019-2021 configuration, with the time-based component remaining identical to the Canadian figure.
- The 36-month time interval is shared across both the USA and Canadian market rows, meaning the calendar-based trigger for a fluid check is consistent regardless of the distance-based unit used in each market.
- Configurations starting from 2021 in both the USA and Canadian markets carry the same 1.2-liter capacity and identical interval specifications as the 2019-2021 rows for their respective markets, indicating no change in fluid service requirements at that model year boundary.
