Oil Change Interval:
Typically every 10,000 miles or 12 months, whichever comes first, using synthetic oil.
Transmission Fluid Change Interval:
Recommended at 60,000 miles or 5 years, especially for the ZF 6HP26 automatic transmission, though sealed for life is also an interpretation by some.
Coolant Replacement:
Initial fill for 5 years/100,000 miles, then every 2-3 years or as specified by coolant type.
