I recall reading somewhere that the Hybrid drive required maintenance every 2 years, yet I cannot seem to figure out what specific maintenance is required.
My car is 8000 miles past its major service interval and I cannot find anything directly related to the hybrid drive maintenance other than these items:
Clutch: Change brake fluid; perform test and adaptation (Cayenne S Hybrid only)
Transfer gear (Cayenne Diesel, S Hybrid, V6): Change oil
What am I missing?
Those don't seem directly related to the Hybrid drive other than the transfer gear fluid.
