To replace the serpentine belt on a Mercedes A-Class, access the lower part of the vehicle: here you will find the serpentine belt on the side of the engine compartment near the right front wheel. By loosening the central nut on the tensioner pulley, you can completely remove the serpentine belt from its position, allowing you to install the new replacement part.

After the replacement, re-tension the belt by reinstalling the pulley and then check that everything functions correctly.

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.
