Additional Notes

  • The Scion iQ EV (USA), KPJ10, carries a 2.9-liter automatic transmission fluid capacity, which applies to a hybrid transmission system rather than a conventional automatic gearbox.
  • Under normal use conditions, the service specification for the KPJ10 calls for a fluid check at 30,000 miles or 36 months, with no fluid change interval listed for that condition.
  • Under severe use conditions, the same 2.9-liter capacity applies, and the service schedule adds a fluid change interval of 60,000 miles or 72 months on top of the 30,000-mile or 36-month check interval.
  • The presence of both a check interval and a separate change interval under severe use reflects a two-stage service approach, where the fluid level and condition are assessed well before a full replacement is due.
  • The 2013 Scion iQ EV KPJ10 is the sole configuration represented in the automatic transmission fluid specifications for the iQ model in the USA and Canada.
