While I was in my car, I noticed that the Master's reset mileage did not decrease correctly, although I kept pressing the button and turned the contact back to 10 to reset it again, counted back from 10 and stopped at zero. As far as I know, when he descended from 0 A, he had to write 20 thousand km. After trying various key combinations to see 20 thousand texts there, I held down two keys at the same time. And this has led to something very beautiful. As long as I hold down, the brightness of the incremental displays has decreased. With the same process again, the brightness came gradually. I never knew this feature and never expected it. I like it very much and there may be situations where it really is necessary. I think it will be useful for those who do not know, but I do not think there are many who know this :)) Meanwhile, when he took the key from the contact and put it back again, he wrote it there as 20 thousand km.
