Hello! I need some tips, because our i20 is driven by the daughter, who studies far away in Greifswald. Supposedly the climate does not go or only insufficient. The car has only 53,000km on it. My questions go in the direction of operation before a Hyundai representative is visited, which is unfortunately not available at the study site, which significantly increases the effort. 1. The climate is switched on when the lights are on? 2. The effect is independent of the adjustment function. g the air currents? 3. Can you read the refrigerant level yourself? 4. How long does the climate take now at 25 degrees and more until it reaches noticeably? 5. What can I pass on to information? Thank you for information!
