Additional Notes

  • The rear differential fluid capacity across all listed GLA-Class X156 configurations is 0.74 liter, a figure consistent with a compact rear differential unit rather than a larger axle assembly requiring a higher service fill volume.
  • The Mercedes-Benz GLA 250 4MATIC (156.946) covering 2014-2020 carries only a capacity specification for the rear differential, with no change interval listed in the row data.
  • The GLA 45 AMG 4MATIC (156.952) entries specify a rear differential fluid change interval of 10,000 miles or 12 months under normal use conditions, whichever comes first.
  • The 10,000-mile or 12-month interval on the GLA 45 AMG 4MATIC reflects a time-based ceiling alongside the mileage threshold, meaning calendar time alone can trigger a fluid change even when mileage accumulation is low.
  • The GLA 45 AMG 4MATIC data appears across two overlapping year ranges, 2014-2015 and 2015-2020, both sharing identical capacity and interval specifications of 0.74 liter and 10,000 miles or 12 months.
  • The rear differential capacity of 0.74 liter applies uniformly to both the GLA 250 4MATIC and the GLA 45 AMG 4MATIC despite the performance difference between the two engine variants, indicating a shared rear differential housing across the X156 4MATIC lineup.
