Additional Notes

  • The rear differential fluid capacity across all listed Cadillac XT4 E2XX (EU) configurations is 0.9 liter, a figure consistent with a compact rear drive module rather than a traditional axle housing, where service fill and total capacity are effectively the same value.
  • The XT4 350D AWD, introduced from 2021, carries a normal-use rear differential fluid change interval of 240,000 km, which is notably longer than the intervals specified for the petrol-engined variants in the same lineup.
  • Under severe-use conditions, the XT4 350D AWD rear differential fluid change interval is halved to 120,000 km, while the fluid capacity remains unchanged at 0.9 liter regardless of use condition.
  • The XT4 350T AWD in the 2020-2022 model years specifies a rear differential fluid change interval of 120,000 km under normal use, placing it at the same interval as the 350D AWD under severe-use conditions.
  • The XT4 350T AWD from 2023 onward retains the same 0.9 liter rear differential capacity and 120,000 km normal-use change interval as the 2020-2022 350T AWD specification, indicating no revision to the rear differential service schedule between those production periods.
