The perfect efficiency of the spark plugs is very important for the regular operation of the engine as they determine the ignition of the mixture: it is advisable to replace them regularly. Before installing the new spark plugs, first check the electrode gap with a feeler gauge and remove the socket screwed in at the location of the connector.

Then unclip the connector and unscrew the old spark plug (it is recommended to perform this operation with the engine cold and one spark plug at a time); insert the new one by screwing it in manually first and then tightening it with the spanner without exceeding the torque.

How to reset the tyre pressure warning light on the Kia Niro EV?

To reset the tyre pressure warning light on the Kia Niro EV, inflate the tyres until they reach the correct pressure value. This value is indicated on the sticker attached to the driver's door pillar. Once the tyres are inflated, turn on the instrument cluster to check that the warning light has completely disappeared from the display. If it is still present, you may need to drive for a few miles to ensure it disappears completely from the screen.
