Additional Notes

  • Across all Mercury Mariner configurations from 2005-2011, the transfer case fluid capacity is uniformly 0.35 liter, a figure consistent with the compact transfer box units found in small SUV platforms of that era.
  • The 2.3 16V (2005-2008) and 3.0 V6 (2005-2008) configurations, both automatic and manual gearbox variants, share an identical check interval of 15,000 km or 12 months under normal use conditions.
  • The Mercury Mariner 3.0 V6 (2005-2008) is specified with two distinct transfer case entries, one for automatic gearbox 4x4 applications and one for manual gearbox 4x4 applications, yet both carry the same 0.35 liter capacity and 15,000 km / 12-month check interval under normal use.
  • The 2.5 16V AWD (2009-2011) and 3.0 V6 AWD (2009-2011) non-hybrid configurations list only a 0.35 liter capacity under normal use, with no check or change interval specified in the row data.
  • The Mariner Hybrid 2.5 16V AWD (2009-2011) is the only configuration in the dataset to carry a fluid change interval, and under normal use conditions, a change is specified at 150,000 miles, with a check interval set at 15,000 miles.
  • Under severe use conditions, the Mariner Hybrid 2.5 16V AWD (2009-2011) transfer case fluid change interval drops substantially to 60,000 miles, reflecting the more demanding operating environment that a severe classification represents.
  • The Hybrid 2.5 16V AWD (2009-2011) is the only variant in the lineup with a severe-use row, meaning a dedicated shortened change interval of 60,000 miles applies exclusively to that powertrain configuration.
