How to reset the oil change reminder on the 2020–2023 Hyundai Sonata
See also: Oil life reset by brand.
Hyundai handles the oil reminder through the Service Interval menu in the instrument cluster’s User Settings (on some models, in the infotainment Settings). The newer manuals list three items there: turn Service Interval on or off, Adjust Interval to set the time and distance, and Reset after an oil change. Older manuals (for example the 2018 Sonata) say to consult a Hyundai dealer to use the menu.
Oil change tips
- 2.5L: buy 6 quarts and check the dipstick.
- 1.6T: one 5-quart jug.
- Hyundai lists a “drain and refill” volume. After refilling, run the engine for a minute, turn it off, wait a few minutes and check that the level is between the F and L marks on the dipstick before adding more.
