I have a 68 plate Yaris, which I bought new earlier this year. It has auto high beam, but it doesnt seem to work at slower speeds, maybe under 30mph or so. Doing a lot of driving on very small and uneven country roads/tracks, I am often driving below that speed. Is there a way to turn off the auto high beam and manually activate it? At the moment, I am having to drive holding the stick pulled towards me, like you do when you're just flashing your lights, which is absolutely not ideal.
