Suzuki Swift, RZ, AZ

Additional Notes

• The Suzuki Swift 1.2 4WD (2017-2020) transfer case carries a fluid capacity of 0.38-0.44 liter, a range that reflects the tolerance between a drain-and-refill service fill and the unit's total internal volume.
• The Swift 1.2 Hybrid 4WD covering the 2017-2020 period shares the same 0.38-0.44 liter transfer case capacity as the non-hybrid 1.2 4WD of the same years, indicating a common transfer case unit across both powertrains in that generation.
• For the 2020-2024 Swift 1.2 Hybrid 4WD, the transfer case capacity range widens to 0.38-0.48 liter, with the upper bound 0.04 liter higher than in the preceding generation, pointing to a revised or updated transfer case assembly.
• Under normal and preferred use conditions, the 2017-2020 Swift 1.2 4WD and 1.2 Hybrid 4WD transfer cases are subject to a fluid level check at 30,000 km or 24 months, with a full fluid change not required until 150,000 km or 120 months.
• The 2020-2024 Swift 1.2 Hybrid 4WD retains the same normal-use service intervals as the earlier generation: a check at 30,000 km or 24 months and a change at 150,000 km or 120 months.
• Under severe use conditions, the change interval for the 2017-2020 Swift 1.2 4WD transfer case drops sharply to 30,000 km or 24 months, which is the same interval used only for a fluid level check under preferred conditions, illustrating how operating environment significantly compresses the service schedule.
• The severe-use change interval of 30,000 km or 24 months applies equally to the 2020-2024 Swift 1.2 Hybrid 4WD transfer case, aligning with the pattern established across the earlier configurations.
• Both preferred and alternative (acceptable) fluid designations for the 2017-2020 Swift 1.2 4WD and 1.2 Hybrid 4WD transfer cases share identical capacity figures and service intervals, meaning the choice between fluid types carries no difference in scheduled maintenance timing.
