INFINITI Q40, V36 (USA)

Brake fluid capacity & service interval

INFINITI Q40, V36 (USA) models utilize brake fluid with a capacity range between min and max. Service intervals occur every 20000 miles or 24 months. The data covers 2 configurations.

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

TypeSpecifications
Q40 (2015-2015)
  • Use: Normal
  • Between min and max.
  • Change 20000 miles/ 24 months
Q40 AWD (2015-2015)
  • Use: Normal
  • Between min and max.
  • Change 20000 miles/ 24 months

Additional Notes

  • The INFINITI Q40 brake fluid fill level is defined by the reservoir's minimum and maximum markers rather than a fixed volume, which is standard for hydraulic brake systems where the fluid level reflects pad wear rather than a measurable drain-and-fill quantity.
  • Both the standard Q40 and the Q40 AWD share an identical service interval of 20,000 miles or 24 months, whichever comes first, under normal use conditions.
  • The 24-month time limit on the brake fluid change interval reflects the hygroscopic nature of brake fluid, meaning the fluid absorbs moisture from the atmosphere over time and degrades regardless of mileage accumulated.
  • The AWD configuration carries no deviation in brake fluid service specifications relative to the rear-wheel-drive Q40, with both variants specifying the same fill guidance and the same change interval for the 2015 model year.
