Being doing a fair bit of night driving lately and have a question, when set on Auto and travelling on a busy 2 way road, high beam activates and the matrix works very well, shutting off part of the beam when oncoming lights detected. However, when travelling down very dark, unlit lanes, of which there are many where I live, the lights stay on dipped beam and I have to manually select high beam using the stalk. Is this normal or is there a problem?
