Scion iQ (USA / CAN)

Brake fluid capacity & service interval

Scion iQ (USA / CAN) uses brake fluid with a capacity range between min and max. Service intervals include checks at 8000 km or 5000 miles/ 6 months, and changes at 48000 km or 64000 km. The data covers 5 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • All configurations across both the USA and CAN markets specify a "between min and max" fill level rather than a fixed volume, which is standard for brake fluid reservoir servicing where the level is verified visually against reservoir markings rather than measured by quantity.
  • The Scion iQ 1.3 (CAN), NGJ10 for the 2012 model year carries a change interval of 64000 km, while the same engine and chassis code for 2013-2015 carries a shorter change interval of 48000 km, representing a reduction of 16000 km between the two Canadian specification periods.
  • The Canadian market iQ 1.3 specifies a check interval of 8000 km across both the 2012 and 2013-2015 specification periods, meaning the inspection frequency remained consistent even as the fluid change interval was revised downward.
  • USA market specifications for the iQ 1.3 (NGJ10) across both 2012 and 2013-2015 state a check interval of 5000 miles or 6 months, whichever comes first, without listing a separate fluid change interval in the provided specifications.
  • The iQ EV (USA), KPJ10 for 2013 also specifies a hydraulic brake system check at 5000 miles or 6 months under normal use conditions, aligning with the interval structure used for the USA-market 1.3-liter configurations despite the EV powertrain being a distinct platform.
  • The dual-condition check interval of 5000 miles or 6 months applied to USA configurations reflects a time-based threshold alongside a distance-based one, which accounts for vehicles that accumulate low mileage over extended periods, since brake fluid absorbs moisture over time regardless of distance driven.
