DS DS 5, K

Automatic transmission fluid capacity & service interval

The DS DS 5, K uses automatic transmission fluid with capacities varying by configuration, including 7 liters (dry fill), 3-4 liters (service fill), 2.2 liters (dry fill), and 2.1 liters (service fill). The data covers 5 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The DS 5 K automatic transaxle configurations for the 1.6 BlueHDi 115 (BHX), 1.6 BlueHDi 120 (BHZ), 1.6 THP 165 (5GZ), and 2.0 BlueHDi 180 (AHW) engines all share an identical fluid capacity profile across the 2015-2018 model years.
  • A dry fill capacity of 7 liters applies to the four automatic transaxle variants listed above, representing the total system volume filled from a fully drained or rebuilt state, such as after a complete overhaul or new unit installation.
  • The service fill capacity for those same four variants is listed as 3-4 liters, reflecting the partial volume exchanged during a routine fluid change where residual fluid remains in the torque converter and passages.
  • The gap between the 7-liter dry fill and the 3-4 liter service fill on the automatic transaxle variants indicates that roughly half or more of the total fluid volume is retained in the system during a standard drain-and-fill procedure.
  • The DS 5 2.0 HDi HYbrid4 (RHC) uses a semi-automatic transaxle rather than a conventional automatic unit, and carries a notably smaller dry fill capacity of 2.2 liters for the 2015-2018 period.
  • The service fill capacity for the semi-automatic transaxle in the 2.0 HDi HYbrid4 is 2.1 liters, which is nearly equal to the 2.2-liter dry fill figure, suggesting very little fluid is retained in the system during a routine service drain.
  • All five configurations across the 2015-2018 range are specified under normal use conditions, meaning the listed capacities and intervals apply to standard operating environments rather than severe or extended-duty cycles.
