  • Transmission: P810 CVT transmission, 4.1 qt (3.9 L) total fill, WS fluid.

  • Brake fluid grade: read it off the reservoir cap.
  • The fluid specification is named by the source - buy a fluid that lists it.

Source: AMSOIL Auto & Light Truck lookup. Capacities are total system fills; a drain-and-refill takes less. Where no fluid specification is shown, the source lists only a catalog code, so use the specification printed in your owner's manual - the wrong transmission fluid damages a transmission.

Gear counts (for example "10-speed automatic") are from the U.S. EPA / DOE fuel economy listing for the same engine.
