Battery down!

Hello dear Land Rover fans, I have only been driving my first Range Rover Evogue since August and was so far more than satisfied. But yesterday I was very disappointed by this High-Tec vehicle…because if it could still cook, I would move in, it or get married. I wanted to go to dinner with my wife yesterday. Castle the garage open and I noticed that I had left the light on my range. What was my mistake, of course, I would like to go ahead. of course I tried to start my range again, but of course I didn’t, because he was standing there for almost 24 hours. Now, however, I remembered that the saleswoman told me that there was such a miracle switch in my range, which is called the undervoltage switch. It would cause the range itself to go down when he notices that the battery is going to the end. But unfortunately, he couldn’t do that. I didn’t push my range out of the garage because my automatic switch didn’t move up any more and I couldn’t put it on neutral. And the hand brake didn’t loosen up there either. However, because I’m well equipped, I had a charger that I could then connect to the battery, and so I could still drive with my wife Essen a little bit later. My questions, which I would have: Do you have to use this undervoltage switch somewhere in the Bordco My second question, how can I turn on/turn on the neutral switch when my car doesn’t concern me anymore? My regards Tanja
