Additional Notes

  • The Subaru Tribeca (B9) power steering system carries a capacity of 0.8-0.9 liter for the 2006-2008 B9 Tribeca, representing the total fluid volume held within the reservoir and system lines during a service fill.
  • From the 2008-2009 generation onward, the power steering capacity settles at a fixed 0.9 liter across all remaining model year ranges, compared to the variable 0.8-0.9 liter range specified for the earlier 2006-2008 B9 Tribeca.
  • Under normal use conditions, the power steering fluid check interval is 15,000 miles or 15 months across all model year ranges covered in the specifications, from 2006 through 2014.
  • Under severe use conditions, the check interval is halved to 7,500 miles or 8 months, applying consistently across all model year ranges from 2006 through 2014.
  • The severe use check interval of 7,500 miles or 8 months paired with the 0.8-0.9 liter capacity applies specifically to the 2006-2008 B9 Tribeca, making that generation the only one in the specifications where both a variable capacity range and a shortened interval appear together.
  • The fixed 0.9 liter capacity combined with the 7,500-mile or 8-month severe use interval applies identically across the 2008-2009, 2009-2011, and 2011-2014 model year ranges, indicating no capacity or interval differentiation among those three generations under severe conditions.
