This is a screenshot of the owner manual.Pretty sure you have a TPMS button as opposed to the touchscreen method on the EX and above.
(2017 LX)Note the 2nd paragraph regarding the 30 mins of drive time. If you don't do this, the light will come back and then you have to recalibrate again. I bought a new 2017 civic hatchback and the dealership never calibrated the TPMS. Light came on half hour later indicating low tire pressure. Once recalibrated, the problem went away.
