Replacing the auxiliary belts is fairly simple since they are positioned at the front of the engine and there is enough maneuvering space to work; there are actually two belts, one dedicated to the air conditioning compressor and the other driving the alternator, water pump, and power steering pump.

Before removing the belts, it is advisable to take note of their routing around the various pulleys; start with the air conditioning compressor belt, loosen the tensioner, and slide the belt off the pulleys; repeat the same process on the other belt.

How to Reset the Tyre Pressure Warning Light on a Kia Rio?

The tyre pressure warning light displayed on the instrument cluster of the Kia Rio can be reset by inflating the tyres until they reach the recommended pressure value: this value is indicated on the sticker affixed to the driver's door pillar. Once all tyres have been inflated to the recommended pressure, turn on the ignition to check that the light has disappeared: if it is still present, it may be necessary to drive for a few miles, allowing the sensors to work and thus turning off the light.
