On Mercedes A-Class and B-Class models produced until 2012, the battery is located under the driver's footwell. Accessing it is extremely simple: first, remove the mat, then unscrew the retaining clip of the footwell with any flat tool, such as a flathead screwdriver.

Once the footwell is removed, there you have it! The battery is in an unusual location, which is why many people struggle to locate it. When replacing the old battery, always disconnect the negative terminal first, followed by the positive. Remove the old battery, insert the new one, and proceed in reverse for reassembly.

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.
