To clean the injection system, disconnect the four rubber hoses that lead from the filter to the injectors. Connect the rubber hoses in pairs to create a 'bridge' so that the fuel remains recycled in the filter during cleaning.

Using silicone tubes, connect one end to the rigid pipe that connects to the injector and insert the other end into a perfectly clean container where the appropriate cleaning additive will be poured. Start the engine and check that the level of the additive in the container remains constant.

Run the engine until almost all the additive is absorbed. Now that the injectors are clean, refit the filter hoses.

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.
