The Kia Niro Mk1 (DE) 2016-2022 was built from the ground up as a dedicated hybrid, offered as a full hybrid, plug-in hybrid and the all-electric e-Niro on a single body. After servicing, its modules expect the maintenance data to be cleared. An oil service reset through the cluster removes the change-oil prompt on the petrol-hybrid versions, and a service reminder reset clears the maintenance light. Owners often also need a TPMS reset after a wheel change, a steering angle reset following alignment, and a brake pad wear reset where fitted. The 12V auxiliary battery, mounted in the boot on hybrids, may require registration after renewal. Select the reset procedure for your Niro below for tailored guidance.

The 12 V auxiliary battery is in the boot/luggage area, not the engine bay. Disconnect the negative terminal there; never touch the orange high-voltage cabling.
With the ignition on, use the EPB service procedure before changing rear pads — see the guide below; it retracts the calipers safely.
