Additional Notes

  • The Buick Rendezvous (USA / CAN) rear differential fluid capacity is 1.9 liters across all four AWD configurations covered in the specifications, spanning the 3.4 V6, 3.5 V6, and 3.6 V6 24V engine variants.
  • A 1.9-liter capacity for a rear differential is a relatively modest volume, consistent with compact-to-midsize crossover rear drive units rather than larger truck-based differentials, which commonly hold 2.5 liters or more.
  • All four configurations carry a normal use condition tied to a 12-month check interval, meaning the interval applies to standard operating conditions rather than severe-duty cycles such as towing or off-road use.
  • A 12-month check interval for differential fluid is a condition-monitoring schedule rather than a mandatory drain-and-fill interval, indicating the fluid level and condition are to be inspected annually rather than replaced on a fixed mileage basis.
  • The 3.4 V6 AWD configuration appears across two overlapping row entries covering 2001-2003 and 2003-2005, both specifying identical 1.9-liter capacity and 12-month check intervals, with 2003 representing a shared model year between the two entries.
  • The 3.6 V6 24V AWD variant, covering 2003-2006, carries the same 1.9-liter rear differential capacity as the 3.4 and 3.5 V6 configurations, indicating no capacity difference despite the larger and more advanced 24-valve engine architecture.
  • The 3.5 V6 AWD configuration, introduced for 2005-2007, maintains the same rear differential fluid capacity and check interval as the earlier 3.4 V6 entries, reflecting continuity in the rear drive unit specification across the engine transition.
