How to Care for Automotive Leather?

First, apply a layer of polish to genuine leather seats. This not only enhances the shine but also adds a protective coating to the seats. This method is relatively simple and can be done by car owners at home (manual scrubbing): For semi-aniline leather jackets, use quick brushing and wiping (mix half a bowl of water with 8 drops of LV cleaner for color protection, then add 20 drops of high-end leather surface cleaner). When cleaning full-aniline leather jackets, start by dampening with water, then brush and wipe simultaneously. The cleaning process for the inner lining of the jacket is the same as for glossy leather jackets.

What is the reason for the Mercedes GLK300 eyebrow light not working?

Mercedes GLK300 eyebrow light not working may be caused by a power supply failure leading to the entire light not functioning, or external power supply issues (such as poor contact, open circuit, insufficient voltage, etc.). Power supply failure causing the entire light not to work: However, generally LED light beads are connected in series and parallel, so under normal power supply conditions, the entire light usually does not go out completely—only part of it may not light up. External power supply issues: If the light itself is not working, it is generally caused by a power supply failure or an open circuit or damage to the light source. Troubleshooting procedure: Check external factors first, then internal; start with simple checks before moving to complex ones.
