Additional Notes

  • Across all listed configurations of the INFINITI EX, J50 (EU), the power steering system holds a capacity of 1 liter, which is a typical figure for a passenger car rack-and-pinion or recirculating ball power steering reservoir fill.
  • The EX30D J50 covering 2010-2011 carries a check interval of 15,000 km or 12 months under normal use conditions, whichever comes first.
  • For the EX30D J50 in the 2011-2013 period, the check interval increases to 20,000 km while the 12-month time limit remains unchanged, resulting in a longer distance-based service window compared to the earlier 2010-2011 specification for the same engine variant.
  • The EX37 J50 spanning 2008-2010 shares the 15,000 km or 12-month check interval with the early EX30D specification, despite being a different engine variant.
  • The EX37 J50 covering 2010-2013 retains the same 15,000 km or 12-month check interval as the 2008-2010 EX37 specification, meaning no interval revision was applied to the petrol variant across that model year span.
  • All four rows are designated for normal use conditions, meaning the stated intervals apply to standard operating environments rather than severe or demanding duty cycles.
  • The 1-liter capacity figure is consistent across both the diesel EX30D and petrol EX37 variants, indicating no difference in reservoir size between the two engine families within the J50 platform.
